Dogs and cats play an important role in modern society, enhancing the psychological and physiological well-being of many people. However, there are well-documented health risks associated with human animal interactions. More specifically, enteric pathogens of zoonotic risk which are transmitted by feces of dogs and cats can be grouped as follows: (a) Parasites such as Toxocara canis, T. cati, Ancylostoma sp, Uncinaria sp, Strongyloides stercoralis, Echinococcus granulosus, E. multilocularis and Dipylidium caninum (b) Protozoa including Toxoplasma gondii, Giardia duodenalis and Cryptosporidium spp. (c) Bacteria of the genera Clostridium, Campylobacter, Salmonella, Escherichia, Yersinia and Helicobacter and (d) Viruses mainly Rotaviruses and Coronaviruses. Among them, Salmonella, Campylobacter, Rotaviruses, Toxoplasma gondii, Echinococcus have been reported to be of considerable importance for many countries including Greece. Even though official records of the cases in humans and livestock in Greece continuously decline, cystic echinococcosis is considered to be a serious problem for public health and livestock economy. Regarding other parasites, the overall prevalence of parasitism was 26% in owned shepherd and hunting dogs examined in Serres. Furthermore, seroepidemiological studies revealed the presence of antibodies against T. gondii in a considerable percentage of hospitalized children. Rotaviruses were confirmed as a major cause of acute gastroenteritis in children. Finally, bacterial zoonotic enteropathogens were identified in a notable number of pediatric cases. Most of these zoonoses are associated with the exposure of immunodeficient people or children to pets and/or conditions of poor hygiene. Studies on the presence of all these pathogens in animals are required to identify the extent of problem, to define control strategies and evaluate their effectiveness.

Introduction:To determine the prevalence of immunoglobulin G (IgG) and immunoglobulin M (IgM) anti-Toxoplasma gondii antibodies among pregnant and postpartum women attended within the public healthcare system in Niterói, State of Rio de Janeiro, and to detect possible exposure factors associated with T. gondii infection in this population. Methods: IgM and IgG anti-T. gondii antibodies were investigated in 276 pregnant and 124 postpartum women by using the indirect immunofluorescence (IFAT) and immunoenzymatic assay (ELISA) techniques. The participants were selected by convenience sampling. All these 400 patients filled out a free and informed consent statement, answered an epidemiological questionnaire and were informed about the disease. Results: Among the 400 samples analyzed, 234 (58.5%) were reactive to IgG anti-T. gondii antibodies, according to the IFAT and/or ELISA assay. One pregnant woman was found to be reactive to IgM anti-T. gondii antibodies, with an intermediate IgG avidity test. Risk factor analysis showed that seropositivity was significantly associated (p<0.05) with age, contact with cats and presence of rodents at home. Through a logistic regression model, these associations were confirmed for age and contact with cats, while education at least of the high school level was found to be a protective factor. Conclusions: The prevalence rate of IgG anti-T. gondii antibodies in the City of Niterói was high and the risk factors for infection detected after multivariate analysis were: age over 30 years, contact with cats and education levels lower than university graduate level.

“…Additionally, Kodjikian et al, in France attributed the development of strabismus to the macular location of lesions in 86% of cases [19]. A number of studies have reported similar observations, with the development of strabismus in pediatric patients ranging from 36% to 70% [20,21].…”
