This paper describes the first record of the critically endangered gravid female Spiny butterfly ray, Gymnura altavela (Linnaeus, 1758), in the northern Mediterranean and simultaneously the only record of the species in this century for the Adriatic Sea. The female (173 cm disc width and 43.25 kg total weight) was captured at approximately 200 m, off Vlorë in the southern Adriatic Sea off Albania on 12th of May 2022. Upon necropsy, seven near-term fetuses (mean 328 ± 6.47 mm disc width and mean 355 ± 20.06 g in total weight) were transported for further in-vitro incubation. These results represent the deepest capture for the species, as well as the largest litter size and largest size at birth in the Mediterranean Sea which indicates the need for further research.

Bovine tuberculosis is a chronic disease of a zoonotic character that occurs in cattle and a wide range of domestic and wild animals. In this paper, bovine tuberculosis caused by M. caprae in six small household herds in Bosnia and Herzegovina was described. For the identification of the disease and determination of the causative agent comparative tuberculin skin test (TST), pathomorphology, microbiology and molecular methods were applied. Twenty-eight cows from five households from the Livno region (25/28 animals) and one household from the Vitez region (3/28 animals) were euthanized after being found positive by the comparative TST test. Eleven animals from five households from the Livno region (9/11 animals) and one household from the Vitez region (2/11 animals) were subject to field necropsy, and lesions consistent with tuberculosis were observed on the lymph nodes of the thoracic cavity and lungs in all carcasses. Histopathologic examination by hematoxylin and eosin staining co...

Non-tuberculous Mycobacteria (NTM) are worldwide opportunist pathogens which can infect both humans and animals. Infections with these mycobacteria can have various clinical manifestations and may cause allergic sensitisation of the infected animals. Besides the potential zoonotic risk these infections in cattle can interfere with intradermal tuberculin test and hamper the in vivo diagnosis of bovine tuberculosis resulting in significant economic losses due to unnecessary restrictions and culling of reactor animals. Here we describe a case of Mycobacterium terrae infection in a cow on a small dairy household in Central Bosnia and Herzegovina. For the identification of the disease and causative agent comparative tuberculin skin test (TST), pathomorphology, microbiology and molecular methods were applied. At necropsy of a cow that was positive on annual routine tuberculin skin testing, severe multifocal granulomatous dermatitis and paniculitis were observed. Furthermore, moderate gran...

This paper describes the occurence of listeriosis in silage fed domestic sheep of the Pramenka type. The aim was to investigate causes of death of animals with previously manifested nervous signs. According to the Law on Veterinary Medicine in Bosnia and Herzegovina, the brain of sheep showing nervous signs of illness must be examined with suspicion on Listeria monocytogenes infection. The disesase occured in the region of Eastern Bosnia in February, 2009. The sheep affected were adult, gravid females. All sheep affected by disease shared similar clinical signs: dyspnea, increased heart rate, circling, staggering, torticollis and inappetence. No abortions of gravid sheep were noted. All simptoms were lasting for 3 to 4 days with lethal outcome and mortality of 5%. The administration of procaine benzylpenicillin showed no results. The necropsy of death sheep revealed encephalitis. Histopathologically, multifocal microabscesses containing mainly degenerated and viable neutrophils, pe...

A case of combined hepatocellular and cholangiocelular carcinoma was diagnosed in a 9 year old male Rottweiler. Clinical examination pointed out possible neoplastic changes in the liver. By histopathological examination of liver tissue an extremly rare case of combined primary canine liver carcinoma, histologicaly composed of hepatocellular and cholangiocellular components, was diagnosed. This primary hepatic tumor is extremely rare in dogs. Key words: canine, hepatocellular carcinoma, cholangiocellular carcinoma

We here describe a case of Mycobacterium terrae infection in a cow in a small dairy household. At necropsy of the cow otherwise positive on routine annual tuberculin skin testing, severe multifocal granulomatous dermatitis and panniculitis, and moderate granulomatous (parasitic) colitis were observed. Histopathology revealed granulomatous dermatitis. Bacteria isolated from regional and thoracic lymph nodes, and skin lesions were identified by colony morphology, biochemical testing and molecular methods as M. terrae. Our findings confirm the difficulties that non-tuberculous mycobacteria can cause in vivo diagnosis of mycobacterial infections, especially in conjunction with parasitic infestations. Key words: Cattle, Mycobacterium terrae, Granulomatous dermatitis, Bosnia and Herzegovina

The angular rough shark, Oxynotus centrina (Linnaeus, 1758), is a poorly known and rare bathydemersal shark inhabiting continental shelves and upper slopes with a significant lack of data and rarely published records in the Adriatic Sea in this century. In this paper, we present 20 new occurrences recorded from May 2015 to September 2021, of which 19 are in Croatian and one in Montenegrin territorial waters. Records of juveniles, subadults and adults are reported. Higher number of records off the Kornati archipelago in the central Adriatic Sea suggest that this area is of particular importance for this species. Furthermore, habitats in the Southern Adriatic might have lower density. Due to the nonsystematic research and nonprobabilistic data collection, it is difficult to establish whether the greater number of records in the continental shelf is just an ostensible phenomenon.

The aim of the present study was to investigate the histopathological changes on the kidneys of the brown trout (Salmo trutta m. Fario) inflicted by per os lead poisoning in the 46-week experimental period. The fish were kept in well-oxygenated freshwater basins. Approximately calculated toxic doses of lead-acetate for fish were 550 mg/kg. Following the experimental period, fish organs, in particular kidneys, were examined by light microscopy. Only fish with lesions observed in kidneys were further examined by electron microscopy. An accumulation of proteinaceous material in the glomeruli of the kidneys, and thickening of the basal membrane were observed histopathologically. This proteinaceous material was also observed in the lumina of the kidney tubules. Electron microscopic examination completely supported this finding. Furthermore, to the authors' previous knowledge, undocumented damage of the brush borders of the proximal kidney tubules was also observed.
