“…Animal age was estimated by dental evaluations, as described by Costa (2015) and the clinical signs observed were the presence of jaundice, hepatomegaly, abdominal distension, and weight loss, which are clinical signs observed in platynosomiasis. The livers were collected during necropsy and analyzed through a section of the bile ducts to verify the presence of trematodes.…”

Platynosomiasis is a hepatopathy caused by Platynosomum illiciens(= P. fastosum) (Trematoda: Dicrocoelidae), which occurs mainly in domestic and wild cats in tropical and subtropical areas. The objective of this study was to verify the occurrence of P. illiciens infection in domestic cats in the city of Araguaína, Tocantins, Brazil, using necropsy and coproparasitological tests. Additionally, we aimed to evaluate the use of two different techniques to diagnose P. illiciens infection in domestic cats and verify whether this parasitism was associated with individual feline characteristics. For this, 54 cats of different ages were analyzed. The percentage of infection was 33.3% (CI = 21.1-47.5%), parasite load was 9-509, mean intensity was 151.7, and mean abundance was 50.5 trematodes per animal. The risk of infection was higher for females than for males (OR = 5.00; P = 0.017). The spontaneous sedimentation coproparasitological test demonstrated the greatest sensitivity and specificity in diagnosing P. illiciens. This study is the first to report the occurrence of P. illiciens in cats in the state of Tocantins, northern Brazil.

“…A contributing factor is that many owners allow their cats to roam freely in the streets, where the animals can ingest prey contaminated with T. gondii. Not only domiciled cats but also stray cats, which are considered more susceptible to contact with this parasite, can shed oocysts in the environment after they become infected (Dabritz & Conrad, 2010;Costa, 2015).…”

Molecular methods such as Copro-PCR stand out in the diagnosis of T. gondii, because they are highly sensitive and specific, and can distinguish T. gondii from other morphologically similar coccids. The purpose was the detection of Toxoplasma gondii copro-prevalence by polymerase chain reaction in 149 fecal samples from stray and domiciled cats, using three distinct markers (B5-B6, 18S and 529bp RE). Oocysts of T. gondii/H. hammondi were detected in 15.4% by parasitology fecal tests (PFT), and 4% of these oocysts were positively identified as T. gondii by Copro-PCR. The presence of T. gondii genetic material was detected in 16.1%, but 12% of the samples that tested positive by Copro-PCR were negative in PFT. Samples with discordant results were subjected to a new Copro-PCR with 18S marker and a 529, and of the 17 samples, 9 contained T. gondii genetic material. A comparison of the PFT and the molecular methods showed the latter was more sensitive, since it detected 22.1% while the PFT detected 15.4%. Demonstrating the high sensitivity and specificity of the Copro-PCR, particularly with the association of primers (k=0.809), but also confirms the importance of using molecular techniques in laboratories, since Copro-PCR was able to detect samples considered negative by PFT.
