We examined 70 breed, between 4 months 8 years age. Complete blood count parameters measured, renal was performed....

Abstract Although the incidence of neoplasms increases with age, some tumors occur more commonly in younger dogs. Still, little information is available on occurrence dogs up to age 24 months. This study a retrospective review histopathological diagnoses neoplasia at our laboratory during last seven years (2017–2023) two groups dogs: group 12 months and from 13 In total 3704 found different dog tissues, 74 (2.00%) were identified 135 (3.64%) aged Canine cutaneous histiocytoma was most...

Abstract Although Mycobacterium avium subspecies are generally not considered food pathogens, the infections caused by these particular nontuberculous mycobacteria (NTM) can represent a serious threat to immunocompromised population. Additionally, with member of Avium Compex (MAC) affect efficiency BCG vaccines used for humans. In infected animals, M. may be present in different tissues without apparent clinical symptoms and macroscopic lesions. Veterinary meat inspection would then fail...

The lymphatic organs of 50 pigs from a total eight farms located at different sites in the epizootiological region North Bačka County were studied to obtain data on prevalence circoviral infections Serbia. All examined had clinical signs suggestive postweaning multisystemic wasting syndrome (PMWS). underwent necropsy and tissue samples taken for histopathological, immunohistochemical (IHC) PCR analysis. presence porcine circovirus 2 (PCV2) was established by analysis tested. most frequent...

Abstract Swine respiratory diseases represent one of the most frequent health issues in pig production worldwide. Despite great progress that has been made field diagnostics, control and prophylaxis, still remain challenging problem modern commercial production. The list infectious agents cause swine is extensive includes both, bacterial viral pathogens. In Serbia, more than fifteen years after introduction vaccines, pathogens related to infections include Mycoplasma hyopneumoniae ,...

African swine fever (ASF) has been detected in many European countries since its introduction Georgia 2007. Serbia suffered first case of ASF the domestic pig population 2019. At beginning 2020, was wild boars open hunting grounds southeastern region country districts along country's borders with Romania and Bulgaria. Since then, all outbreaks boar were clustered located same bordering areas. Despite newly implemented biosecurity protocols for hunters 2019, time June 2021 an enclosed ground...

Out of the total number canine tumors examined at Department pathology based on biopsy and section materials over last five years skin mammary gland were proved to be two largest groups diagnosed in 33.4% 36% cases, respectively. Cutaneous 211 i.e., 123 (58.3%) male dogs 88 (41.7%) bitches, different breeds, average 7 old. Among tumors, 32 types cutaneous neoplasms diagnosed, with epithelial melanocytic being most predominant, followed by hematopoietic mesenchymal soft tissues. In our...

In this work, 36 canine livers with fibrosis were examined. Based on the degree of fibrosis, classified into three groups: 1- mild portal fibrosis; 2- moderate periportal and septal 3- severe marked or cirrhosis. Normal liver sections obtained from five dogs no evidence infectious, neoplastic, cardiovascular diseases used as controls. The was evaluated stained according to Masson's trichrome method. It proved using an immunohistochemical method that HSC periductal myofibroblasts are...

Abstract Canine distemper virus (CDV) is a worldwide distributed RNA that can cause severe disease in carnivore and non-carnivore species. Red foxes are highly susceptible may act as reservoir of the virus. As other wild species, red manifest acute, systemic chronic nervous form. In present study, we detected antibodies against CDV among Western Serbia, analyzed histopathologically immunohistochemically for nuclear protein antigen (CDV-NP) brain samples derived from seropositive animals....
