Introduction: causes pythiosis in humans and animals in tropical and subtropical climates. The clinical manifestations in humans are mostly systemic, vascular or ocular forms, in contrast to animals, which are cutaneous, subcutaneous and gastrointestinal forms. The highest incidence of human cases is reported in Thailand, however, no canine pythiosis has been documented yet.
Case Presentation: A female, mixed-breed, stray dog showed severe extensive ulcerative haemorrhagic dermatitis at the perineum involving the anus and tail. On cytology, there were sparse branching septate fungal hyphae. The tissue samples were subjected to polymerase chain reaction and gene sequencing for fungal identification.
Conclusion: The results of the internal transcribed spacer 1 and 2 (ITS1 and ITS2) gene had 99 % homology to (accession no. FJ17396) and the gene (accession no. GQ451572). The phylogenetic tree of both genes was classified in clade A This is the first fully documented diagnosis of canine cutaneous pythiosis in Thailand.

Introduction: Ensuring accuracy in the diagnosis of leishmaniasis is crucial due to the myriad of potential differential diagnoses. Given the inherent limitations of serological techniques, real-time polymerase chain reaction (qPCR) emerges as a superior alternative. Furthermore, parasitological methods, conventionally regarded as the gold standard owing to their high specificity, encounter challenges concerning sensitivity and invasiveness for patients.

Background: We standardized two recombinase polymerase amplification (RPA) assays coupled with lateral flow (LF) strips for the detection of Leishmania braziliensis and Leishmania infantum kinetoplast DNA (kDNA).
Methods: The RPA-LF assays were tested at different temperatures and reaction times, using DNA from cultured L. braziliensis and L.

Mast cell tumors (MCTs) are common skin neoplasms in dogs. Prognostic indicators include histologic grade, clinical stage, high Ki-67 index, elevated argyrophilic nucleolus organizer regions (AgNOR) index, mutations, and recurrence after surgery. Blood serum redox status has been shown to correlate with prognostic factors in canine lymphoma and mammary tumors.

Cardiovascular involvement in Leishmania sp. infections still requires further elucidation, with cutaneous and organic changes being more frequently observed. The aim of this study was to conduct a systematic review of cardiovascular involvement in dogs with canine visceral leishmaniasis, considering a publication span of over 80 years.

Worldwide, a variety of mycobacterial species have been associated with skin lesions in dogs and cats. Lesions may result from systemic dissemination or local cutaneous inoculation. Only infections with Mycobacterium tuberculosis complex organisms have the potential to be transmitted from companion animals to humans, but even then, zoonotic risk is considered low.
