The risk assessment of antimicrobial resistance is very important to determine the risk of decreasing antimicrobial efficacy can be used as a basis for policymakers in allowing or prohibiting the use of an antimicrobial. This study aims to assess the risk of using colistin against E. coli resistance in the broiler flock. Risk assessment is carried out qualitatively using primary data, interviews, and secondary data. To obtain primary data various studies were carried out including monitoring the prevalence of colistin-resistant E. coli and mcr-1 also mcr-2 genes in broiler flocks, mcr-1 gene transfer from E. coli to Salmonella Enteritidis, mcr-1 gene sequencing, mutant selection windows of colistin against E. coli, and also multiresistant of E. coli colistin-resistant. Assessment of the risk of E. coli colistin-resistant in the broiler flocks through direct contact with live broiler flock environment with the resulting assessment is a medium risk with low uncertainty. Since colistin sulfate is very critically important for humans, the reduced use of colistin sulfate in animal production is necessary to reduce the risk of resistance. Reducing the use of colistin sulfate requires the collaboration of various sectors such as the government, veterinary drugs industries, farmers, and consumers.

Subclinical mastitis has a higher prevalence than clinical mastitis in many small farmers in Bogor city, and it could reach more than 80 percent. However, the application of teat-dipping could help small farms to control subclinical mastitis prevalence. The objective of this study was to measure the cost of teat-dipping application as subclinical mastitis control in small dairy farms. The partial budget was employed based on the experimental data collected in small dairy farms in Bogor. A number of cows were the basis of simulation for the mean of milk value and the application cost. The findings show an incentive for farmers to apply teat dipping in their farms. The incentive of teat dipping application could be improved to prevent sub-clinical mastitis infection and increase milk production.

Cryptosporidial infection is one of the most common causes of diarrhea in humans and livestock worldwide. This study was conducted to estimate the prevalence of Cryptosporidium infection and to identify potential risk factors associated with shedding of oocysts in Bogor. A total of 308 faecal samples were collected from 136 calves less than 6 months, 44 from those 6-12 months and 128 from those than 12 months. Data of factors potentially associated with the likelihood of Cryptosporidium spp. infection were recorded (i.e., enviromental status, size of herd, and herd management). Cryptosporidium spp. oocyst was identified by using modified acid fast (Ziehl Neelsen) staining technique and microscopically examined under 400x magnifition. Results showed that the prevalence of cryptosporidiosis in Bogor was 21.1% (CI 95%; 16.5%-25.6%). The highest prevalence was 29% (CI 95%; 26.8%-31.7%) in cattle aged less than 6 months. The oocysts abundance were around

The Aceh cattle are local Indonesian beef cattle that are farmed in Aceh Province. This type of cattle is one of the sources of meat for the Aceh people. This study aims to analyze the quality of two primal cuts (longissimus lumborum and semitendinosus muscle) from Aceh cattle based on the muscle microstructure characteristics and MSTN gene expression. This study used a sample of longissimus lumborum and semitendinosus muscles from 18 adult male Aceh cattle with the age of 2–2.5 years and a BCS of 3.24. Muscle samples were obtained shortly after the cattle were slaughtered in slaughterhouses in Banda Aceh and Aceh Besar districts. Muscle microstructure analysis was performed using the HE, Masson’s trichrome, and immunohistochemistry staining methods, while the MSTN gene expression analysis was performed using the qPCR method. The analysis of the physical quality of meat includes pH, meat color, fat color, cooking loss, water holding capacity, and WBSF value. The results showed that the area of LL muscle fibers was smaller than that of ST with relatively the same diameter. Both muscles were dominated by fast fibers with a percentage of 82.37% (LL muscle) and 91.80% (ST muscle). The area and composition of the type of muscle fibers are the main factors that influence the tenderness of Aceh beef. A higher distribution of collagen was found in ST muscles than in LL muscles. MSTN gene expression in both muscle types was relatively the same. Aceh cattle have large muscle fibers and are dominated by fast fibers with a high percentage, resulting in a low level of the tenderness of Aceh beef. However, the level of tenderness of Aceh beef is still in accordance with the cooking preparation of original and favorite cuisine of Aceh people.

This study aims to evaluate the economic potential of Aceh cattle from the perspective of stock farmers, traders, and consumers as the three main players in the business. This study was conducted from June to August 2018 in Banda Aceh City and Aceh Besar District, Aceh Province, Indonesia. It used related literature and a survey method that involved interviews, observations, and questionnaires from 9 stock farmers, 23 traders, and 22 consumers to obtain data. The data presented descriptively and analyzed using SWOT (strengths, weaknesses, opportunities, and threats) analysis. The results show that the strength factors of the Aceh beef business are high selling prices, easy maintenance, the good taste of meat, and that do not shrink quickly when cooked. Meanwhile, the weakness factors are the limitation of the availability of seeds, traditional methods of assessing carcass weight during the buying and selling process, and the low productivity of the cattle compared with other breeds. The factors that become opportunities include the high demand for the beef, on both weekdays and religious holidays, the selling price tends to increase each year, and the government's commitment to increase local cattle productivity through various programs. However, there are certain threats to the development of these cattle, and they include the high price of calves, competition with other more productive breeds, the existence of other cheaper sources of animal protein, and a decrease in consumer purchasing power. The difference between the value of the strength and weakness factors was 0.12, which signified a positive result, while that between the opportunity and threat factors was −0.29, which signified a negative result. Furthermore, the coordinate value from the Cartesian field shows that the development of these cattle is in quadrant IV, which means that the prospect for development is still quite high, regardless of the threat. In conclusion, Aceh cattle have a high economic potential to be developed, which needs to be strengthened through the rebranding program while at the same time maintaining the sustainability of the Aceh cattle breed in Indonesia. Meanwhile, the government is expected to supervise and regulate the trade of these cattle to provide beef at an affordable price for consumers.

Flying foxes have been considered to be involved in the transmission of serious infectious diseases to humans. Using questionnaires, we aimed to determine the direct and/or indirect contacts of flying foxes in an Indonesian nature conservation area with domestic animals and humans living in the surrounding area. We surveyed 150 residents of 10 villages in West Java. Villages were classified into 3 groups: inside and/or within 1 km from the outer border of the conservation area and 1-5 km or 5-10 km away from the reserve's outer border. Data were collected by direct interview using a structured questionnaire consisting of the respondent characteristics (age, sex and occupation); histories of contacts between flying foxes and humans, dogs and other domestic animals; and knowledge about infectious diseases, mainly rabies, in flying foxes. We found that flying foxes from the nature conservation area often enter residential areas at night to look for food, especially during the fruit season. In these residential areas, flying foxes had direct contacts with humans and a few contacts with domestic animals, especially dogs. People who encounter flying foxes seldom used personal protective equipment, such as leather gloves, goggles and caps. The residents living around the conservation area mostly had poor knowledge about flying foxes and disease transmission. This situation shows that the population in this region is at a quite high risk for contracting infectious diseases from flying foxes.

This study is aimed to estimate the prevalence of resistant Salmonella spp., determine the spread of bacterial resistance and investigate the serotypes of bacteria in the chicken’s digestion tract in the broiler farms in Subang District. As many as 74 farms were chosen, five poled caeca samples were taken from each farm and tested for isolation and identification of Salmonella spp. Salmonella isolates obtained were tested antimicrobial susceptibility against 8 antibiotics using the agar dilution method. The antibiotics were gentamycin, tetracycline, ciprofloxacin, nalidixic acid, ampicillin, chloramphenicol, trimethoprim, and sulfamethoxazole. The result showed that 8 out of 74 samples were positive for Salmonella . The prevalence of Salmonella spp. in the digestion tract was 10.8%; 95% confidence interval 3.7%-17.9%. Based on the serological test eight serotypes obtained were Salmonella enteritidis, Salmonella oslo, Salmonella narashino, Salmonella nakuru, and Salmonella nordufer. The result of antibiotic resistance test showed that from 8 Salmonella isolates obtained, 12.5% were found to be sensitive, 75% isolates were resistant to one or two antibiotics, and the remaining 12.5% isolates were resistant to more than two antibiotics; 95% confidence interval (0%-35.4%). The prevalence of resistant Salmonella spp. bacteria in chicken digestion tract in broiler farms in Subang District was high, so integrated control program to reduce antimicrobial resistance problem in broiler farm are greatly needed.

Colistin is the last drug choice for dealing with the carbapenem-resistant Enterobacteriaceae bacteria; hence, this drug is very crucial to human health. The discovery of a plasmid-mediated colistin-resistant gene, the mobilized colistin resistance-1 ( mcr-1 ), signals a significant global health threat. Colistin sulfate is an antimicrobial agent which has been approved for use in broilers in Indonesia. Thus, this study aimed to measure the prevalence of colistin-resistant E. coli and to detect the mcr-1 colistin-resistant gene in E. coli, and E. coli O157:H7 in the entire supply chain of broilers in Bogor Regency, West Java Province, Indonesia. Samples were taken from 47 flocks that used colistin sulfate (47 samples of cloacal swabs, 47 samples of drinking water, and 47 samples of litters), seventy fresh meat samples and seven samples plucker swabs from seven small-scale poultry slaughterhouses, seventy fresh meat samples from seven traditional markets, and seventy cooked meat samples from seven small restaurants. The isolation of E. coli was done on each of the 358 samples, and 493 isolates were obtained. All the E. coli isolates were then tested for their susceptibility to colistin sulfate by using the agar dilution method. The detection of the mcr -1 gene from the colistin-resistant isolates (minimum inhibitory concentration > 2 µg/mL) was conducted using the polymerase chain reaction (PCR). The prevalence value of colistin-resistant E. coli in all the isolates was at 11.76% (CI 95%; CL 9.21–14.91%), and the prevalence of mcr -1 gene was at 10.55% CI 95%; CL 8.13–13.57%). A very good agreement correlation existed between the colistin-resistant phenotype and the mcr-1 gene (ĸ = 0.939). The mcr-1 gene was found in 89.66% colistin-resistant E. coli isolates. The two colistin-resistant and mcr - 1 carrying gene isolates were identified as E. coli O157:H7 serotype. This research was the first study attempt on the mcr -1 gene in Indonesia, covering the entire supply chain of broiler meat from farms to consumers. The results indicated the necessity to reduce the use of colistin sulfate in broiler management and to improve biosecurity measures, not only in farms but also in the entire supply chain of broiler meat production.

African Swine Fever (ASF) is a highly contagious hemorrhagic viral disease that attacks pigs and wild pigs causing economic losses for farms small and large scale. ASF outbreaks that occurred in several regions in the world have caused unrest for the livestock sector. The rapid spread of the ASF virus has resulted in very high pig mortality. ASF virus transmission can occur through direct or indirect contact. Urine and faecal excretion of pigs is an important route of ASF transmission. The ASF virus has three transmission cycles, namely the silvatic, domestic and wild boar cycles. Outbreaks that occur in several countries encourage the strategy of controlling and overcoming the disease through surveillance. ASF disease control that has been carried out includes improving farm biosecurity management systems and limiting the movement of animals and animal products before the ASF vaccine is found.

This study aimed to determine the prevalence and associated risk factors of coccidiosis. Samples were obtained from 400 dairy cattle (196 calves aged 12 months). Feces samples were collected, examined and counted for prevalence and number of oocyst per gram faeces (OPG) by McMaster technique. A questionnaire was design to record information about animal health and husbandry, individually. Risk factors associated with the prevalence of Eimeria in cattle were analyzed by logistic regression model. The overall prevalence and the average of OPG of Eimeria in cattle was 179 (44.75%) and 286.75, while highest prevalence of Eimeria was observed in calves aged less than 6 months. Cattle aged more than 12 months showed significantly different relationship (P

The aims of this research were to estimate the prevalence and to determine the risk factors related to Toxocara cati (T. cati) infection in pet cats in Bogor. This study was cross sectional study using two types of data; laboratory examination results of feces samples and interview results of the cat owner using a structured questionnaires including characteristics of pet owner and pet care management. The data obtained from this study was analyzed using chi-square test. The results showed that 85 of 243 cats were positively infected by T. cati with 35% prevalence. The significant risk factor associated with the T. cati infection were: sex, sand provided, deworming and type of feed. Pet care management in Kota Bogor were well managed, however the prevalence of T. cati infection was still high. Therefore it can be a potential public health problem especially on cat owners.

Aceh cattle serves as the first choice in providing beef in Aceh Province, Indonesia. This study was aimed to measure the area of muscle fibers in Aceh cattle and its correlation with the meat tenderness. The study used semitendinosus muscle samples from four Aceh bulls aged 18-30 months with an average body weight of 320.75±71.41 kg. The paraffin sections were stained with hematoxylin-eosin (HE) staining, while muscle samples were processed for meat tenderness measurement. The measurement of the area of muscle fibers was carried out under a light microscope and by using IMAGE J software, while the analysis of meat tenderness was done using the Warner-Bratzler Shear Force (WBSF). The results were compared with reference values in Bali cattle and Ongole grade cattle. The average area (μm2) of muscle fibers in Aceh cattle was 2 752.17 (95% CI: 1 334.34-4 170.00). This value is not different from those of Bali cattle and Ongole grade cattle. WBSF value (kg cm−2) in Aceh cattle was 9.35 (95% CI: 4.21-14.49). The average of WBSF value in Aceh cattle was higher but not significantly different from those of Bali cattle and Ongole grade cattle. The study concluded that beef of Aceh cattle is as tender as the beef of Bali and Ongole grade cattle.

Coccidiosis is one of the most widely distributed parasitic diseases of cattle throughout the world. Coccidiosis infection in ruminants was caused by Eimeria spp. The objective of this study was to determine Eimeria species composition and various factors influencing Eimeria oocysts shedding in dairy farm. This study was conducted with a cross-sectional study design in dairy farm in South Bandung District from July 2014 to January 2015. Samples were obtained from 400 dairy cattle (196 cattle at age 12 months). Fecal samples were collected, examined and counted for Eimeria species composition and numbers of oocysts per gram of feces (OPG) using McMaster technique. A questionnaire was completed for individual dairy cattle farmer to record information about cattle’s health and husbandry. The effect of cattle’s sex, age and type of pen flooring to OPG values were analyzed using Mann-Whitney and Kruskal-Wallis tests. The Kruskal-Wallis test was performed followed by Dunn test as a multiple comparison test. Ten species of Eimeria were identified in all infected cattle. Among the Eimeria identified species, Eimeria bovis was found to have the highest prevalence (42.5%), followed subsequently by Eimeria wyomingensis (39.1%), Eimeria bukidnonensis (32.4%), Eimeria pellita (26.3%), Eimeria auburnensis (19.6%), Eimeria zuernii (17.3%), Eimeria cylindrica (3.9%), Eimeria canadensis (3.9%), Eimeria brasiliensis (3.4%) and Eimeria alabamensis (1.1%). The numbers of oocysts shed was correlated significantly ( p < 0.05) with cattle’s sex and age as well type of pen flooring which influenced the infection pressure. Younger calves aged less than 6 months shed the highest amount of Eimeria oocysts than older cattle. Many factors may cause the increasing number of OPG in fecal samples. Therefore, it is important to keep good sanitation and control of Eimeria among dairy cattle in the KPBS Pangalengan dairy farm.

The finding of P. falciparum chloroquine resistance (pfcrt) and P. falciparum multidrug resistance 1(pfmdr1) gene in P. falciparum has become an obstacle in treating malaria. The polymorphism between the two genes may result in molecular functions, in cellular components, or in biological processes. The objective of this research is to find similarities between the two genes in 3 components; cellular components, molecular functions and biological processes, based on Gene Ontology. the similarity will be counted semantically by path length approach with Wang m ethod. The range of similarity values is 0-1. After the similarity value examined; in Molecular Function the similarity is 1 due to the same drug transmembrane transporter activity, in Cellular Component is 0,714, the similarity only at the same vacuole food cells, and in Biological Processes is 1 due to the same proces in responding to drug. Therefore, this research proves both genes have similarities based on gene ontology.

Mastitis is udder inflammation that can be caused by the entry of pathogenic bacteria through the teat. One of the treatments that can prevent bacteria infection is teat dipping. This research was aimed to identify the effectof teat dipping after milking to the presence of pathogenic bacteria that cause subclinical mastitis (Staphylococcus aureus, Streptococcus agalactiae, and Escherichia coli) and the presence of pathogenic bacteria that cause subclinicalmastitis by quarter of udder. Milk samples were taken from normal lactation period of dairy cows, clinically healthy, and positive subclinical mastitis status when the intervention was applied. Sixty seven samples of quarters from 18dairy cows were identified to the presence of pathogenic bacteria that cause subclinical mastitis before teat dipping and at 1st, 2nd, and 3rd months after teat dipping. Identification of the presence of pathogenic bacteria was done byculturing samples on selective agar media. The presence of common pathogenic bacteria, Staphylococcus aureus, and Escherichia coli decreased significantly after teat dipping, while Streptococcus agalactiae and other pathogenicbacteria did not decrease significantly. The presence of pathogenic bacteria based on the quarter of udder did not show the significance difference. Application of teat dipping after milking was able to decrease the presence ofpathogenic bacteria that cause subclinical mastitis.

Brucellosis is a zoonosis and occupational diseases transmision. The diseases caused by bacterial and attack multiple species of animals. Common species that infects goats as the most pathogenic species (zoonotic) is Brucella melitensis; however, the species B. abortus could also infect goats. The study purposed to find out the brucellosis seropositive in goat in Jakarta slaughterhouse and to detect caused agent of brucellosis. Sampling was done through slaughtered goats that come from brucellosis endemic area. The samples were collected fromslaughtered mature female goats i.e serum, goat milk, vaginal swab, mamary gland, limphoglandula supramamary, limph, and uterus. The detection method was used i.e patological lession, serological, culture and PolymeraseChain Reaction (PCR) technique. The serological detection of brucellosis in goats was done parallelly between Rose Bengal Test (RBT), Complement Fixation Test (CFT) and Enzyme Linked Immunosorbent Assay (ELISA). The results of this study demonstrated that out of the 119 serum samples serologically tested, negative for RBT, one was positive for CFT and none were positive with ELISA. Patological observation in the Brucella predilection organs, there were 5 goat carcases showed pathological lession (vagina discharge, hemoragy at limphand limphoglandula, crumbly limph and there were pus in uterus). The serum samples that had reacted positively and the organs with pathological lesion were confirmed further with PCR, bacterial isolation and identification.The PCR test results and the culture of milk samples, vaginal swabs and organs did not reveal any Brucella spp bacteria (B. abortus, B. melitensis, B. ovis dan B. suis) and also vaccine strains of RB51. Based on these results, it was concluded that brucellosis in goats on Java Island was a 0.84% seropositive (confidence interval 95%; 0.00826 - 0.00854) (1/119), although the species of Brucella that had infected them remains unknown.
