Seropositivity for Toxoplasma gondii in cats with clinical signs and living in households with women of childbearing age
Toxoplasmosis caused by Toxoplasma gondii is a protozoal zoonosis with high sanitary risk for pregnant women and immunocompromised people. Felids, including domestic cats, are the only definitive hosts of T. gondii. They shed oocysts which, in the environment, become infectious for a wide range of animals, including humans, acting as intermediate hosts. This study evaluated the frequency of acute toxoplasmosis in domestic cats with compatible clinical signs and living in households with women of childbearing age. Individual serum samples were collected from 150 cats and analyzed for IgM and IgG against T. gondii. Statistical analyses were performed to evaluate associations between seropositivity and potential risk factors. Overall, 31 cats (20.7 %) were seropositive for anti-T. gondii antibodies, i.e. 9 (6.0 %) for IgM, 17 (11.3 %) for IgG and 5 (3.3 %) for both. The cats showed different combinations of clinical pictures. The following statistically significant associations were found: male sex and positivity for IgM and/or IgG (p=0.0248; OR= 0.3537; 95 % CI= 0.1528–0.8675), presence of 2 or more clinical signs and positivity to IgM only (p=0.0003; OR= +infinity; 95 % CI= 3.924 to +infinity), presence of either neurological signs (p=0.0025; OR= 13.30; 95 % CI= 3.409–61.39) or ocular signs (p=0.0228; OR= 5.835; 95 % CI= 1.631–22.37) and positivity to IgM only, presence of gastrointestinal signs and positivity to IgG only (p=0.0083; OR= 5.508; 95 % CI= 1.503–18.54). Male sex also resulted a possible risk factor in the binomial logistic regression (p= 0.011; OR= 3.336; 95 % CI= 1.131–8.44). These results indicate that cats living with women of childbearing age are at risk of infection with T. gondii. The presence of certain clinical signs can be helpful in identifying recent and/or current infections using laboratory analyses. Awareness on toxoplasmosis should be kept high to protect animal and public health.
期刊介绍:
The journal Veterinary Parasitology has an open access mirror journal,Veterinary Parasitology: X, sharing the same aims and scope, editorial team, submission system and rigorous peer review.
This journal is concerned with those aspects of helminthology, protozoology and entomology which are of interest to animal health investigators, veterinary practitioners and others with a special interest in parasitology. Papers of the highest quality dealing with all aspects of disease prevention, pathology, treatment, epidemiology, and control of parasites in all domesticated animals, fall within the scope of the journal. Papers of geographically limited (local) interest which are not of interest to an international audience will not be accepted. Authors who submit papers based on local data will need to indicate why their paper is relevant to a broader readership.
Parasitological studies on laboratory animals fall within the scope of the journal only if they provide a reasonably close model of a disease of domestic animals. Additionally the journal will consider papers relating to wildlife species where they may act as disease reservoirs to domestic animals, or as a zoonotic reservoir. Case studies considered to be unique or of specific interest to the journal, will also be considered on occasions at the Editors'' discretion. Papers dealing exclusively with the taxonomy of parasites do not fall within the scope of the journal.
