The taxonomic classification within the SIG has evolved with molecular techniques distinguishing five species. Despite their similarities, these species exhibit varied host affinities, with unclear implications for virulence and host interaction.

A reliable diagnosis is crucial because of the zoonotic potential of dermatophytes. The routine mycological diagnostic procedures for dermatophytosis are widely known, but in the case of some isolates, identification based on phenotypic characteristics may be incorrect.

Canine atopic dermatitis (CAD) is a common, chronic, inflammatory skin disease in dogs worldwide. This disease often predisposes for secondary organisms overgrowth and skin infections with pathogens, such as and . Unfortunately, the causes of this disease in both humans and animals are not fully understood; therefore, the only possible option is a lifelong, symptomatic treatment.

Despite the importance of in veterinary and human medicine, studies concerning the AMR of this bacterium are still scarce. A total of 65 strains, isolated from dogs and cats, were assessed to test for susceptibility to six clinically relevant antimicrobials via a microdilution method.

However, the data about the virulence and genetic relationships of strains isolated from these wild ruminants are strongly limited. The aim of this study was to investigate the prevalence of infections in the European bison, and to evaluate the genetic diversity of isolates from these animals.

Caprine arthritis-encephalitis (CAE) is caused by the same pathogen; however, the presence of CIP has been only occasionally reported in SRLV-infected goats. We carried out a cross-sectional study to determine the prevalence of histopathological lesions indicative of CIP in goats with symptomatic CAE, and to investigate whether CIP was associated with a higher prevalence of other types of pneumonia (purulent bronchopneumonia, fibrinous pleuropneumonia) or bacterial infections.

The molecular epidemiology of high-level mupirocin-resistant isolates could be assessed by the determination of their IS257-ileS2 spacer regions conformation. In this study, 188 isolates of methicillin-resistant staphylococci were subjected to the detection of HLMR, and analysis of the conformation of the IS257-ileS2 spacer regions.

In this study, resistance to tetracycline was investigated in 114 isolates from livestock and European bison. Tetracycline minimum inhibitory concentration (MIC) was evaluated by a microdilution method, and tetracycline resistance genes were detected by PCR.
