In this study, we conducted post-mortem examinations of golden jackals (Canis aureus) and red foxes (Vulpes vulpes) from the northern region of the Republic of Srpska (Bosnia and Herzegovina) to detect the presence of Angiostrongylus vasorum. An epidemiological survey was conducted in the densest golden jackal population in the country. Over two time intervals, we examined a total of 30 jackals and 16 foxes.

Article Synopsis
  • Ovine anaplasmosis, caused by the tick-borne Anaplasma ovis, is a blood disease affecting sheep, leading to symptoms like mild anemia and fever, with potential severity in non-endemic regions.
  • In a study of blood samples from 81 sheep in Bosnia and Herzegovina, 46.9% tested positive for A. ovis, with a notable co-infection rate of 63.3% alongside Babesia ovis and a higher prevalence in the Herzegovina area.
  • The genetic analysis of A. ovis shows diverse genotypes and significant variability, suggesting that local environmental factors influence the emergence of these new genotypes in the region.

Article Synopsis
  • The study assessed the prevalence of Staphylococcus aureus subclinical mastitis in lactating cows, finding it to be 5.4%, with higher risks on small and medium-sized farms.
  • The research identified 44 S. aureus genotypes, including 15 new ones, and noted differences in gene frequency related to adherence and enterotoxin production between new and known genotypes.
  • Methicillin-resistant S. aureus (MRSA) strains were more common on larger farms, highlighting the effectiveness of molecular techniques for understanding and managing staphylococcal infections in dairy cattle.

Nocardia cyriacigeorgica is a well-known agent of human nocardiosis and is considered an emerging pathogen, however, its identification to the species level is complex for many clinical laboratories. Available data on the clinical significance of N. cyriacigeorgica in veterinary medicine are sparse and mainly concern isolated reports of pyogranulomatous lesions in domestic animals.

Malignant ovine babesiosis or ovine babesiosis caused by Babesia ovis is an important hemoprotozoan tick-borne disease of sheep. After 70 years, a study was conducted in Bosnia and Herzegovina, in the geographical areas of Podrinje and Eastern Herzegovina, aiming to molecularly identify and determine the presence of B. ovis infection in the sheep population.

Nasal swabs originating from 112 apparently clinically healthy and unvaccinated horses of different age, breed and from diverse rearing conditions from Serbia and Bosnia and Herzegovina were examined for the presence of equine herpesviruses 1, 4 and 5 using multiplex nested PCR (Mn‑PCR) and virus isolation. The detected viruses were subsequently characterised by gB gene nucleotide sequencing and their phylogenetic analysis was performed. The infections with EHV‑1, EHV‑4, and EHV‑5 in the examined horse populations are apparently chronic, subclinical and persistent, whilst the shedding of EHV‑1 and EHV‑5 was confirmed by their successful isolation.

This case study describes the presence of a deer ked (, Linnaeus, 1758) in the Balkan chamois () from the area of the National Park "Sutjeska", Bosnia and Herzegovina (B&H). This is the first finding of this ectoparasite in this animal species in B&H, which indicates that deer ked has significant adaptive abilities to different animal hosts.

We report two cases of bovine babesiosis caused by Babesia divergens in a region of central Bosnia and Herzegovina. The cases were detected in June 2017 and July 2018 from two small backyard farms. Routine clinical assessments, including physical examination and haematology, revealed lethargy, fever, anaemia, leukopenia and haemoglobinuria in the affected animals.

Objective: To evaluate the etiology of skeletal changes noted in equid vertebrae from a 19- century context near Belgrade, Serbia.

Materials: A vertebral column consisting of 15 fused thoracic vertebrae (T2-T16), with right ribs fused to T4 and T5 and small remnants of ribs articulating with T4, T5 and T6 on the left side were accidentally recovered during industrial exploitation of sand.

Methods: The specimen was subjected to morphological analysis and collagen fingerprinting by mass spectrometry for species identification.

Article Synopsis
  • This case report discusses a rare mixed infection in a European wildcat caused by two parasitic species: Aelurostrongylus abstrusus and Angiostrongylus chabaudi, marking the first documented instance of this in Bosnia and Herzegovina.
  • The wildcat experienced severe health issues, including bronchopneumonia and infections from additional gastrointestinal parasites like Toxocara cati, highlighting the serious effects of these parasites in wildlife.
  • The study provides a thorough examination of the bronchopneumonia's pathology, details the morphology of the parasites, and employs molecular techniques like triplex PCR to confirm the diagnosis, expanding understanding of these neglected parasites' impact on European wildcats.

Aims: This case report describes a clinical case of patent and natural infection with trichuroid Eucoleus aerophilus in a 5-month-old, mixed-breed female dog in Bosnia and Herzegovina.

Methods: A detailed history was taken from the owner. Physical exam and thoracic radiography were performed.

This paper represents the first description of advanced aelurostrongylosis in the Eurasian badger (Меles meles, L. 1758) from Bosnia and Herzegovina, which is an autochthonous species of the country. An adult female badger was found dead on a road; the cause of death was trauma but the emphasis in the paper is on severe verminous pneumonia caused by metastrongylids from genus Aelurostrongylus spp.

From 1929 to 1941, the Vrbas Banate was one of nine provinces of the Kingdom Yugoslavia, and according to historical data, the poorest one, without well-organized and sustainable agriculture production. Naturalistic production and poor animal health control in the Vrbas Banate were the most important risk factors for infectious disease spreading. Anthrax was very prevalent infectious disease in domestic animals and humans in that period, but some data on this disease remain scarce.

Article Synopsis
  • Pathological changes are uncommon in archaeological remains of wild animals, but a case of spavin was identified in a red deer from the Early Neolithic site of Blagotin, Serbia.
  • The analysis revealed new bone formation in the left tarsal joint through macroscopic observations, X-ray, and CT imaging, suggesting aging and environmental factors may have influenced the condition.
  • The presence of spavin in the deer likely caused joint stiffness and lameness, potentially aiding Neolithic hunters in capturing the animal, highlighting that spavin isn't just caused by riding or labor.

The Balkans is endemic for nematodes of the genus Trichinella in both domestic and wild animals. The high prevalence of these zoonotic pathogens in animals linked with the food habits to consume raw meat and meat derived products resulted in a very high prevalence of trichinellosis in humans living in this European region. In spite of numerous epidemiological investigations carried out in this region, very few information is available on the Trichinella species circulating in Bosnia and Herzegovina.

Ethnoveterinary medicine (EVM) considers implementation of folk knowledge and skills in animal health care, production and breeding. Also it means understanding of diagnostic, preventive, therapeutic skills and treatments in order to improve public health. EVM has a wide importance in the organic farming and environmental protection.
