Leishmania spp. diagnosis and therapeutic management in a cat from urban area in Ibagué (Colombia).

BACKGROUND

Leishmania spp., a protozoan transmitted by sandflies, widely affects humans and dogs in Colombia, nevertheless feline leishmaniasis (FeL) remains understudied.

OBJECTIVE

This study reports a case of feline leishmaniasis in Colombia and its therapeutic management.

METHODS

Complete blood count, renal and hepatic serum biochemistry, nodular lesion cytology, FeLV/FIV snap test, abdominal ultrasound, and molecular diagnosis of Leishmania spp. 16 s rRNA gene amplification by real-time-PCR (qPCR), ITS-1 and hsp70 gene by endpoint-PCR and Sanger sequencing were performed.

RESULTS

The patient was negative for FIV/FeLV and showed leukocytosis, lymphocytosis, thrombocytopenia, neutrophilia, monocytosis, hypergammaglobulinemia, increased gamma-glutamyl-transferase, cortical nephrocalcinosis, diffuse heterogeneous splenic parenchyma, and cholangitis. Nodular lesion cytology, qPCR and Sanger sequencing confirmed the diagnosis of Leishmania spp. The patient was treated with allopurinol and miltefosine. After treatment, clinical signs disappeared.

CONCLUSION

Clinical examination, cytology, and molecular tests allowed a rapid and sensitive FeL diagnosis. Allopurinol and miltefosine improved the clinical condition of the cat.
