Caprine Arthritis-Encephalitis Virus Infection was presented with clinical, pathological, and molecular findings in dairy goats from a breeding unit in Turkey. According to history, 50 of 700 goats and kids showed the clinical signs including anorexia, mastitis, swelling of the joints, lameness, dyspnea and head pressing in the past 2 months. Fifteen and 6 animals were examined clinically and pathologically, respectively. Clinical examination revealed depression, weakness, pneumonia, ataxia and paresis in 15 goats. Histological lesions were composed by a varying degree of interstitial pneumonia, nonsuppurative leukoencephalomyelitis, interstitial nephritis and interstitial myocarditis. Immunohistochemical examinations showed the presence of viral antigen in tubular epithelium, in glial cells and macrophages.

This study describes a concurrent occurrence of lower respiratory aspergillosis and pneumoconiosis in a turkey flock. From one flock of 1000 turkeys, 4 clinically affected turkeys were examined pathologically and microbiologically. Clinically affected turkeys showed anorexia, lethargy, drooping of the wing, vomiting, dyspnea and open-beak breathing, or sudden dead. Gross lesions were observed in the air sacs and lungs which presented white to yellowish granulomas of varying size. Microscopic there was multifocal granulomatous airsacculitis and pneumonia. At the center of the granulomas, fungal hyphae were clearly highlighted in the lungs and air sacs by Gomori methenamie silver (GMS) staining. In the microbiological cultivation of the affected lungs and air sacs, Aspergillus fumigatus was isolated on Sabouraud dextrose agar. Furthermore, dark black dust accumulations were present in the cytoplasm of macrophages or interstitial tissue in the lungs and air sacs. There were also fibrosis and lymphohistiocytic cell infiltrations around the particles. Overall, this study could implicated that pneumoconiosis might be a predisposing factor in the development of respiratory aspergillosis in turkeys.

In this study, the effects of Aloe vera gel and coconut oil on wound healing were investigated and compared in rats. Forty-two Wistar albino rats were used during the experiment, in which they were operated on under general anaesthesia to create two full-thickness open skin wounds (created with a 0.5 cm diameter punch biopsy apparatus) on both back sides of the median line. A total of 42 rats were divided into three groups of 14 animals each to receive the topical application of Aloe vera gel (AV group – n = 14), coconut oil (CO group – n = 14) and cold cream (CONT group – n = 14). The medical applications were performed twice a day in all the groups. The wound borders were marked on a transparent sheet every day. Afterwards, this sheet was transferred to the millimetre graph paper. On days 0, 7, and 14, the unhealed wound area was measured in all the groups. On days 7 and 14, seven rats in each group were euthanised. Then, skin samples including the intact skin were taken from the wound sites for histopathological and biochemical evaluations. The topical application of Aloe vera gel showed a significant increase in the healing process of the open wounds in terms of the clinical evaluation, histopathological and biochemical data averages when compared with the coconut oil and cold cream groups of rats (P < 0.05). The results obtained in the present study demonstrate that Aloe vera gel may provide a good alternative for the treatment of open wounds. [ABSTRACT FROM AUTHOR]

A four-year-old Akkaraman ewe was presented to the Firat University Veterinary Teaching Hospital for circling, dullness, weakness and sternal recumbency. On physical examination, opisthotonus, mydriasis in the right eye and myosis in the left eye, absence of the pupillary reflex, ruminal tympany were detected. Serum pituitary hormone analyses indicated the hypopituitarism characterized by thyroid stimulating hormone (TSH) < 0.05 IU/L, follicle stimulating hormone (FSH) < 0.13 IU/L, luteinizing hormone (LH) < 0.10 IU/L and prolactin (PRL) < 0.50 ng/ml. On the basis of clinical presentation and hypopituitarism, tentative diagnosis of pituitary abscess was made. The animal was euthanized due to the poor prognosis. Morphological examination revealed coexistence of hypophyseal-carotid rete abscess and hyaline thrombosis in carotid rete, heteropic ossification in carotid rete and tuberal muscles. Microbiologically;Arcanobacterium pyogeneswas isolated in blood agar culture from the hypophysis. Decreased serum pituitary hormone levels including TSH, FSH, LH and PRL in conjunction with the clinical findings were a useful diagnostic tool for antemortem diagnosis of pituitary abscess in the sheep.

The article presents a study which examines the pathological changes in experimentally induced Astragalus cephalotes toxicity in mice. For the study, an experimental toxicity was induced in Swiss white mice (SWR) through the feeding of standard pellets which contain Astragalus cephalotes. Researchers found clinically, lethargy, tremors, sudden jerks in response to stimuli loss of weight and declined birth rate. They also found vacuolations in the parenchyma cells of the liver, kidneys and pancreas, along with congestion and haemorrhages in the lungs and heart.

This study looked at how spermatogenesis, lipid peroxidation, antioxidant defense mechanisms, and histological changes in testicular, hepatic, and renal tissues were affected by boric acid (H3BO3) added to mixed feed and drinking water at different concentrations for 14 weeks. For this purpose, 60 male Japanese quails (Coturnix japonica f. domestica) were used. From the age of 35 days, the birds were given boric acid added to regular soybean meal maize mixed feed as well as drinking water. Experimental groups: Control (no additive), F100: 100 mg/kg boric acid into feed, F300: 300 mg/kg boric acid into feed, W100: 100 mg/l boric acid into drinking water, and W300: 300 mg/l boric acid into drinking water. Both primordial (P < 0.001) and mature (P < 0.05) sperm counts increased in F300 and W300 groups. Supplemented boric acid in drinking water (300 mg/l) increased the tubule diameters of the testicle (P < 0.05). Because of the rising levels of boric acid in the feed and water groups, lipid peroxidation levels increased in testicular (P < 0.001), hepatic, and renal tissues (P < 0.01). Glutathione (GSH) levels rose in high boric acid groups in testicular and hepatic tissues (P < 0.001). Different tissues responded differentially to high amounts of boric acid in terms of antioxidant enzyme activity (P < 0.001). As a result, boric acid at high doses showed beneficial effects on spermatological activity; however, continued use caused lipid peroxidation in tissues and some pathological problems in liver tissue.

The aim of this study is the detection of prevalence of bovine viral diarrhea virus-1 (BVDV-1) in sheep abortion samples in Turkey. For this purpose, initially, the detection of pestiviruses, bluetongue virus (BTV) and akabane virus (AKAV) was performed by reverse transcription-polymerase chain reaction (RT-PCR) from the aborted sheep fetus specimens. Then, for differentiation of pestiviruses, further investigations were carried out from the pestivirus positive samples. Pestiviruses RNAs were detected from 98 (24.74%) of 396 aborted fetus samples collected from 13 provinces in Turkey. By using border disease virus (BDV) and bovine viral diarrhea virus (BVDV) specific primers, 58 (59.18%) of pestivirus positive 98 samples were detected as BDV and the remaining 40 (40.81%) were found as BVDV with RT-PCR. According to the results, BVDV RNAs were detected from 10.10% (40/396) of aborted fetus specimens. By sequencing and phylogenetic analysis of BVDV positive four samples, BVDV-1 was identified as the genotype of BVDV. The BTV and AKAV genome were not detected from the 396 aborted samples tested in this study. In conclusion, there's a high ratio of BVDV-1 among sheep abortions in Turkey. According to this study results, we think that the high prevalence of BVDV in sheep abortion cases may be important for the control programme against persistent BVDV infections. [ABSTRACT FROM AUTHOR]
