A sensitivity of up to 100% (9/9 cats) has already been reported for this technique (PALUMBO et al., 1974), and it has been observed to have a greater capacity for detecting feline platynosomiasis in comparison to a direct smear, centrifugation in zinc sulfate, or modified detergent and sugar flotations (PALUMBO et al., 1976; KRECEK et al., 2010).

    ABSTRACT: Platynosomiasis is a parasitic infection reported in non-human primates, including marmosets, and is frequently difficult to diagnose. In this study, the Kato-Katz method and the spontaneous sedimentation method were evaluated for their usefulness in identifying "Platynosomum" eggs in fecal samples from "Callithrix penicillata" that naturally harbor "Platynosomum illiciens". Spontaneous sedimentation allowed the diagnosis of 41.7% (5/12) and 66.7% (8/12) of infected marmosets from one and three slides, respectively, prepared from the same fecal sample. The examination of a single Kato‑Katz thick smear detected 83.3 (10/12) of infection cases. The analysis of feces on three different days increased the rate of diagnosis, since 75% (9/12) and 100% (12/12) of the primates with platynosomiasis were identified using serial spontaneous sedimentation (3 slides/day) and the Kato-Katz method, respectively. The mean number of "Platynosomum" eggs per gram of feces determined via the Kato-Katz method was 71.7 (8-240). The spontaneous sedimentation method when performed in series is acceptable for the diagnosis of platynosomiasis. However, the Kato-Katz method, which was here used for the first time to detect this infection, has a higher diagnostic sensitivity and the advantage that a quantitative analysis of the eggs released in the host feces is possible.

    ABSTRACT: The purpose of this paper is to present a review about the most important features of Platynosomiasis in domestic and some wildlife animals regarding to the etiological agent, clinical signs, diagnosis, immunity, treatment and prevention; as well as some imaging diagnostic techniques and its importance to make an accurate diagnosis.

    ABSTRACT: A survey designed to determine the prevalence of Platynosomum concinnum was conducted. A total of 110 cats from different regions of the State of Rio de Janeiro (Brazil) were necropsied. Their livers and gallbladders were examined to observe macro and microscopic alterations and to detect the presence of adult flukes. When found, the flukes were collected, preserved and identified. The prevalence of infected cats in the State of Rio de Janeiro was 37.27% (41/110). There were cats harboring as few as four parasites and cats harboring as many as 2,553 parasites. The adult parasites found had a wide variety in size (2.8 to 6.8 mm in length and 0.85 to 2.6 mm in breadth). The majority of cats (85.36%) had only one size of adult parasites and 14.63% had two sizes of adult parasites. The liver's, macroscopic findings varied from no lesion up to hepatomegaly and dilatation of the biliary ducts. The most frequent histopathological findings were congestion, inflammatory infiltrate of polymorphonuclear and mononuclear cells around the ducts, hyperplasia and increase in the number of biliary ducts and proliferation of the connective tissues. The study concluded that liver fluke infection (P. concinnum is an important health problem in cats of Rio de Janeiro, Brazil.
