ABSTRACT
The objectives of this work were to investigate the occurrence of parasites in feces of cats, compare different coproparasitological techniques for their diagnosis and determine associations with parasitism. The samples were processed using three different coproparasitological techniques: centrifugal flotation in sucrose, centrifugal flotation in ZnSO4 and simple sedimentation. The parasitic association between parasitism and variables such as age, sex and fecal consistency was performed using the chi-square test or the G test with a significance level of 5%. A total of 237 samples were analyzed, of which 93 (39.2%) were positive, being Ancylostoma spp. (17.3%), Giardia intestinalis (12.2%), Platynosomum illiciens (8.0%), Cystoisospora spp. (6.3%), Toxoplasma gondii/ Hammondia hammondi (3.4%), Diphyllobothriidae (2.1%), Toxocara spp. (1.7%), Dipylidium caninum (1.3%) and Mesocestoides spp. (0.8%). In the parasitism association analysis, it was possible to verify a statistical difference in the age category for Cystoisospora spp. (p=0.001) observing a strong relationship between parasitism and young animals, the association with sex proved to be important for P. illiciens (p<0.001) with a higher frequency of parasitized females and fecal consistency revealed to be related to the parasites G. intestinalis (p=0.007) and P. illiciens (p=0.033) showing a higher number of positive animals for these parasites with normal fecal consistency. In conclusion, we observed a higher occurrence of Ancylostoma spp. and G. intestinalis in fecal samples from domestic cats received in routine diagnoses and the presence of other parasites with zoonotic potential, as well as the relationship of these diagnosed parasites with the categories sex, age and fecal consistency.

Amblyomma rotundatum is a tick species commonly found on reptiles and amphibians. In Brazil, investigations of this ectoparasite have indicated its distribution across all Brazilian biomes, although it is concentrated in certain locations. In this context, the objective of the present study was to describe a case of parasitism by A. rotundatum in a red-footed tortoise (Chelonoidis carbonarius) in the state of Rio de Janeiro. A female red-footed tortoise (C. carbonarius), seized by the environmental police, was parasitized by a tick in the left periocular region. The tick was manually removed, preserved in 70º GL ethanol, and sent for identification at the Federal Rural University of Rio de Janeiro (UFRRJ). Based on the morphological evaluation Dantas-Torres et al. (2019), Barros-Battesti et al. (2006) and Lampo et al. (1997), a diagnosis of a female specimen of A. rotundatum was made. In conclusion, this study reports the first case of A. rotundatum parasitizing C. carbonarius in the state of Rio de Janeiro, highlighting the presence of periocular blepharitis associated with this parasitism.
Amblyomma rotundatum é uma espécie de carrapato comumente encontrada em répteis e anfíbios. No Brasil, as investigações desse ectoparasito indicam sua distribuição em todos os biomas brasileiros, embora concentrado em algumas localidades. Nesse contexto, o objetivo do presente estudo foi descrever um caso de parasitismo por A. rotundatum em jabuti-piranga (Chelonoidis carbonarius) no estado do Rio de Janeiro. Uma fêmea de jabuti-piranga (C. carbonarius), apreendida pela Polícia Ambiental, estava parasitada por carrapato na região periocular esquerda. O carrapato foi removido manualmente, preservado em etanol 70º GL e encaminhado para identificação na Universidade Federal Rural do Rio de Janeiro (UFRRJ). Com base na avaliação morfológica Dantas-Torres et al. (2019), Barros-Battesti et al. (2006) e Lampo et al. (1997), foi feito o diagnóstico de um espécime fêmea de A. rotundatum. Em conclusão, este estudo relata o primeiro caso de A. rotundatum parasitando C. carbonarius no estado do Rio de Janeiro, destacando a presença de blefarite periocular associada a este parasitismo.
