RESUMO
Feline sporotrichosis is a zoonotic mycosis caused by fungi belonging to the Sporothrix schenckii complex. In the state of Ceará, there are no reports of isolation of this fungus in cats. This study presents the first report of feline sporotrichosis caused by the species Sporothrix brasiliensis in the state of Ceará - Brazil. The diagnosis was made through cytopathological examination, mycological culture and PCR. The findings were compatible with feline sporotrichosis caused by Sporothrix brasiliensis.
RESUMO
The objective of this study was to detect the presence of anti-Leptospira spp. in samples of humans and domestic animals of forest fragmentation areas in the Brazilian Amazon. A total of 208 samples from dogs, cats, and humans were collected during two expeditions within the same fragment. Detection of anti-Leptospira spp. antibodies was performed by the Microscopic Agglutination Test (MAT) using live antigens from 19 Leptospira spp. serogroups and DNA detection of Leptospira 16S rRNA gene was done using Polymerase Chain Reaction. After the analysis, we observed 24.03% (50/208) of reactive serum samples, where the most prevalent serogroups circulating in the human and animal population were Canicola, Djasiman, Cynopteri, and Serjoe. Leptospira DNA was detected only in the samples of 13 dogs, which demonstrated 100% identity with L. interrogans DNA deposited in the GenBank. We concluded that there is a circulation of Leptospira spp. in the studied fragment.
RESUMO
Hemoparasitoses have become increasingly important in the medical practice of small animals. Among the causative agents we find the genera Ehrlichia spp, Anaplasma spp. and Mycoplasma spp., and it becomes of great importance to know the epidemiology in domestic cats. This research aimed to make a retrospective survey of records of cats that underwent polymerase chain reaction (PCR) examination in the molecular biology laboratory at the Federal Rural University of the Amazon in 2018 and 2019. A total of 72 feline samples were processed, being 33 males and 39 females, 70 SRD animals and 2 Siamese, all with thrombocytopenia, in addition to other clinical signs that led them to need veterinary care, the months of entry and processing of samples, neighborhoods of the animals, categorized by age groups, street access, presence of ectoparasites and contactors were categorized. Higher occurrence of Ehrlichia spp. was described in adult females, while Anaplasma platys, Mycoplasma spp. and concomitant infections were more reported in adult males. We conclude that the cats seen at HOVET had parasitism by different infectious agents.
Hemoparasitoses vêm se tornando cada vez mais importantes na clínica médica de pequenos animais. Dentre os agentes causadores encontramos os gêneros Ehrlichia spp, Anaplasma spp. e Mycoplasma spp., e torna- se de grande importância conhecer a epidemiologia nos gatos domésticos. Objetivou-se com esta pesquisa fazer um levantamento retrospectivo de fichas de felinos que realizaram exame de Reação de Cadeia da polimerase (PCR) no laboratório de biologia molecular, na Universidade Federal Rural da Amazônia, no ano de 2018 e 2019. No total foram 72 amostras de felinos processadas, sendo 33 machos e 39 fêmeas, 70 animais SRD e 2 Siameses, todos com trombocitopenia, além de outros sinais clínicos que os levaram a precisar de atendimento veterinário, foram categorizados os meses de entrada e processamento das amostras, bairros dos animais, categorizados por grupos etários, acesso à rua, presença de ectoparasitas e contactantes. Foi descrita maior ocorrência de Ehrlichia spp. em fêmeas adultas, enquanto Anaplasma platys, Mycoplasma spp. e infecções concomitantes foram mais relatadas em machos adultos. Concluímos que os felinos atendidos no HOVET possuíam parasitismo por diferentes agentes infecciosos.
