Lymphatic filariasis is a mosquito-borne disease that poses a serious public health concern. The disease has spread to 28 Indonesian provinces, with NTT province being one of the 10 provinces with the highest incidence. Aside from being a major supporter of the annual mass drug administration program, the mosquito control initiative is also critical to the disease's eradication. However, today's mosquito control approaches depend primarily on synthetic moieties, which, unfortunately, have resulted in environmental problems and also resistance in important mosquito species. Consequently, developing alternative mosquito control strategies based on herbal components that are environmentally friendly, safe, and long-lasting is necessary. This one-health program aims to educate and raise public awareness of the importance of mosquito control and to inspire the community to utilize local plants as alternative mosquito repellents. This program is targeted high school students from the Timor Tengah Selatan regency. This regency is one of the NTT regencies with the highest risk of lymphatic filariasis. The approach method employed in this program was a series of presentations, discussions, and a demonstration of lymphatic filariasis and the selection of local plants that can be used as herbal repellents. Based on discussions with the students, it was discovered that after engaging in this activity, the participants had learned and recognized the dual function of various indigenous plants in their area as effective and cost-effective mosquito repellents. Furthermore, the students became more excited to learn and develop knowledge about the function of other local plants as efficient mosquito repellents.

African Swine Fever (ASF) is an important infectious disease in pigs caused by African Swine Fever Virus (ASFV). Despite not being zoonotic, this disease has the potential to severely affect the socioeconomic conditions in the impacted regions. The majority of pig farmers in Indonesia, particularly those in Kupang City, that raise pigs in backyards or on a small scale, experience the impact of ASF's effects. Early in 2020, the ASF cases were confirmed in Timor Island, including the Kupang City area in Nusa Tenggara Timur (NTT) Province. The molecular information on ASFV in this area is still limited. In order to determine the homology and nucleotide analysis using BLAST NCBI, the ASFV p72 (B646L) gene fragment sequence from Kupang City was compared to ASFV p72 (B646L) gene segments from other parts of Indonesia and several other Asian countries. The results of nucleotide analysis and sequence homology of the original ASFV p72 (B646L) gene fragment from Kupang City showed a high level of homology to the ASFV p72 (B646L) gene fragment from West Java, North Sumatra, and several Asian countries. The findings from this study indicate that the source of ASF viral transmission across different regions may be comparable. Therefore, to prevent the dissemination of ASF, strict biosecurity measures must be implemented along with monitoring of animal and product transportation.

African swine fever (ASF) is a destructive re-emerging swine disease that has posed a serious economic threat to the global pig farming sector. In past years, ASF has rapidly spread over Europe, Asia, and Oceania, and begin to enter Indonesia in the middle of 2019. The clinical and pathological symptoms of ASF are influenced by the strain's virulence, the transmission pathway, and the pig's immunological and health status. ASF’s clinical manifestations are known to evolve, from after an invasion enters a new free region to after the disease has been established in the territory for a longer period. Identifying ASF clinical signs and pathological changes is crucial for a comprehensive and reliable early detection system. The objective of this research is to observe and identify gross pathology in ASF suspect pigs in order to obtain a better understanding of the cause of death. Two dead pigs from a farm in Oebelo village, Kupang regency, Indonesia with a recent history of massive deaths had been examined in this study. The post-mortem results showed that hemorrhagic splenomegaly and hemorrhagic lymphadenitis were the main lesions observed at the examinations. Furthermore, hemorrhages were also found in various internal organs such as the kidneys, liver, and heart. To determine the exact cause of the pigs' deaths, a molecular diagnostic test should be conducted.

Khairullah AR, Sudjarwo SA, Effendi MH, Ramandininto SC, Gelolodo MA, Widodo A, Riwu KHP, Kurniawati DA, Rehman S. 2022. Profile of Multidrug Resistance and Methicillin-Resistant Staphylococcus aureus (MRSA) on dairy cows and risk factors from farmer. Biodiversitas 23: 2853-2858. Staphylococcus aureus is a facultative anaerobic Gram-positive coccus that causes mastitis and is one of the most widespread pathogenic bacteria in dairy farming. These bacteria can quickly develop into antibiotic-resistant strains due to inappropriate antibiotic administration. Staphylococcus aureus bacteria that have Multidrug-Resistant (MDR) properties can be known as Methicillin-Resistant S. aureus (MRSA) if these bacteria are resistant to beta-lactam antibiotics. The high number of MDR and MRSA contamination in dairy farms as a result of excessive administration of antibiotics in the treatment of dairy cows and the spread of these bacteria cannot be separated from the sanitation management at the time of milking, it can be from milk that is milked from the udder and it can also be from the hands of farmers during the milking process. This study tests antibiotic resistance and detects Methicillin-Resistant S. aureus (MRSA) strains sourced from milk and hand swabs of farmers in Probolinggo, East Java, Indonesia. A total of 109 dairy cow’s milk samples and 41 samples of farmers’ hand swabs were taken from each farm. Samples were cultured and purified using Mannitol Salt Agar (MSA). Staphylococcus aureus resistance profile was performed by disk diffusion test using antibiotic disks such as Oxacillin, Cefoxitin, Tetracycline, Erythromycin, and Gentamicin. Staphylococcus aureus isolates that were resistant to Oxacillin and Cefoxitin antibiotics were then tested for Oxacillin Resistance Screening Agar Base (ORSAB) as a confirmation test for Methicillin-Resistant S. aureus (MRSA). The results of the isolation and identification found 80 (53.33%) S. aureus isolates, then the results of the resistance test found 8 (10%) S. aureus isolates that were Multidrug-Resistant (MDR), and in the Oxacillin Resistance Screening Agar Base (ORSAB) test there were 3 isolates of S. aureus MDR were ORSAB positive. It can be found that there are several S. aureus isolates that are Multidrug-Resistant (MDR) and Methicillin-Resistant S. aureus (MRSA) in dairy farms. The S. aureus that is MDR and MRSA can be spread to the community and will endanger public health. Thus, prevention and control measures are needed to suppress the spread of S. aureus infection on a dairy farm in Probolinggo, East Java, Indonesia.

Classical Swine Fever (CSF) is an important infectious disease caused by the CSF virus, which belongs to the Pestivirus genus from the family Flaviviridae. This disease has a high fatality rate in swine. Stamping out the disease and vaccinations aimed at forming and strengthening antibodies against CSF are proven to be effective ways of disease control and prevention. Several factors, including age, immune status, health status, nutrition, and the environment, are believed to influence the success of the immunization program. Furthermore, it is assumed that different pig breeds may have impacts on vaccination success. This study aimed to compare antibody responses after CSF vaccination in two different pig breeds, Landrace and local Timor pigs. A total of 26 pigs (13 pigs for each group) was occupied in this study. All of the pigs used in this study had never been vaccinated against CSF. Antibody titers were quantified using an ELISA test, then the data were compared using an independent t-test to assess the difference of antibody responses between Landrace and local Timor pigs. Finally, the study found no significant difference in antibody response between Landrace and local Timor pigs, with a significant value of 0.07 (P > 0.05). Therefore, it is feasible to conclude that breed does not influence antibody response following CSF vaccination.

In early 2020 a high mortality of pigs in Malacca Regency, East Nusa Tenggara Province was confirmed as an ASF infection which then spread to all of Timor Island, Flores Island, and Sumba Island. One of the risk factors for the spread of ASF is swill feeding. The purpose of this study was to study the feed management practices of pig farmers during the ASF outbreak and to measure the relationship between feed management practices and the ASF outbreak in Kupang City. The study used a case-control study approach to study feed management practices for pig farmers during the outbreak and their relationship to ASF. A total of 69 farmers who had experienced the incidence of dead and sick pigs were taken as case samples and 21 farmers were randomly selected from around the area as controls. The data in this study were analyzed by descriptive statistics and bivariate analysis was used to measure the relationship between feed management practices and the incidence of ASF. The results of the bivariate analysis showed that swill feeding practice had a significant correlation with the incidence of ASF (P 0.038

African swine fever is a fatal hemorrhagic disease in the Suidae family that has become a significant economic challenge to the global pig farming industry. The continued spread of this disease has threatened global pork production and food security. Recognizing the disease manifestations and pathological changes of ASF is critical for a comprehensive and accurate early warning program. Knowledge of the key characteristics of this disease, such as its pathology anatomy, and histopathology, is also needed for early identification of ASF before establishing a tentative diagnosis. This article aims to discuss the pathologic changes and to update disease understanding in order to improve early detection of ASF in the field. A histopathological study of clinical samples collected during the February to April 2021 outbreak of ASF was performed to determine the characteristic lesions of ASF. Three dead ASFV-suspected pigs from a farm in Kupang regency were examined in this study. The main characteristics at the gross pathology inspection were hemorrhage and enlargement of the spleens and lymph nodes. The histopathologic findings confirmed spleen and lymph nodes hemorrhages, as well as congestion of spleen and follicle necrotic at the lymph nodes. Based on the clinical manifestation, pathological findings, and epidemiology observation, it is suspected that the pigs were infected with ASF. However, a molecular diagnostic test should be taken to confirm the definitive cause of the pig’s deaths.
