“…Vários estudos descrevem a presença de necrose generalizada do intestino em animais infectados por T. gondii como sendo a principal causa de óbito por toxoplasmose (DUBEY et al, 1988;OKSANEN et al, 1996;GUIMARÃES et al, 1997;EPIPHANIO et al, 1999;LIESENFELD et al, 2004;ANDRADE et al, 2007). Além da avaliação morfométrica da parede, em função da diarréia praticamente constante nos animais do G2 e G3, este estudo também investigou a dinâmica de glicoconjugados (mucinas) secretados pela mucosa intestinal por meio do número de células caliciformes marcadas por PAS (mucinas neutras), Alcian Blue pH 2,5 (mucinas ácidas não sulfatadas: sialomucinas) e Alcian Blue pH 1,0 (mucinas ácidas sulfatadas: sulfomucinas) e observou-se diferença significativa somente no número de células marcadas por PAS (Tabela 2).…”

“…However, several other species of New World primates are highly susceptible to clinical toxoplasmosis experimentally and there are many worldwide reports of clinical toxoplasmosis in these animals in captivity (Dubey and Beattie, 1988;Dubey, 2010a). In Brazil, disseminated toxoplasmosis was diagnosed in 3 squirrel monkeys (Saimiri sciureus), 7 golden-headed lion tamarins (Leontopithecus chrysomelas), 3 emperor marmosets (Saguinus imperator), 1 golden-handed marmoset (Saguinus midus), 1 black marmoset (Saguinus niger), 5 wooly monkeys (Lagothrix lagotricha), 1 black tifted ear marmoset (Callithrix penicillata), 1 night monkey (Aotus triviragatus), 1 black lion tamarin (Leontopithecus chrysopygus), 2 golden lion tamarins (Leontopithecus rosalia), 6 brown howler monkeys (Alouatta fusca), and 2 white ear-tufted marmosets (Callithrix jacchus) that were examined post-mortem during 1991 to 2001 (Epiphanio et al 1999(Epiphanio et al , 2000(Epiphanio et al , 2001(Epiphanio et al , 2003; half of these animals died peracutely without any clinical signs. Pneumonitis and hepatitis were the main lesions (Epiphanio et al 2003).…”

Toxoplasmosis in humans and animals in Brazil: high prevalence, high burden of disease, and epidemiology

et al. 2012

View full text Add to dashboard Cite

SUMMARYInfections by the protozoan parasiteToxoplasma gondiiare widely prevalent in humans and animals in Brazil. The burden of clinical toxoplasmosis in humans is considered to be very high. The high prevalence and encouragement of the Brazilian Government provides a unique opportunity for international groups to study the epidemiology and control of toxoplasmosis in Brazil. Many early papers on toxoplasmosis in Brazil were published in Portuguese and often not available to scientists in English-speaking countries. In the present paper we review prevalence, clinical spectrum, molecular epidemiology, and control ofT. gondiiin humans and animals in Brazil. This knowledge should be useful to biologists, public health workers, veterinarians, and physicians. Brazil has a very high rate ofT. gondiiinfection in humans. Up to 50% of elementary school children and 50–80% of women of child-bearing age have antibodies toT. gondii. The risks for uninfected women to acquire toxoplasmosis during pregnancy and fetal transmission are high because the environment is highly contaminated with oocysts. The burden of toxoplasmosis in congenitally infected children is also very high. From limited data on screening of infants forT. gondiiIgM at birth, 5–23 children are born infected per 10 000 live births in Brazil. Based on an estimate of 1 infected child per 1000 births, 2649 children with congenital toxoplasmosis are likely to be born annually in Brazil. Most of these infected children are likely to develop symptoms or signs of clinical toxoplasmosis. Among the congenitally infected children whose clinical data are described in this review, several died soon after birth, 35% had neurological disease including hydrocephalus, microcephaly and mental retardation, 80% had ocular lesions, and in one report 40% of children had hearing loss. The severity of clinical toxoplasmosis in Brazilian children may be associated with the genetic characteristics ofT. gondiiisolates prevailing in animals and humans in Brazil.

“…Little is known of natural epidemiology of T. gondii infection in New World monkeys in the wild. There are many reports of severe acute toxoplasmosis in these animals in capitivity including those in zoos in Brazil [Andrade et al, ; Antoniassi et al, ; Bouer et al, ; Epiphanio et al, ; Epiphanio et al, ; Garcia et al, ; Leite et al, ; Maluenda et al, ; Muñhoz et al, ; Pimentel et al, ; Silva et al, ; Túry et al, ]. A summary of 33 cases of acute toxoplasmosis in New World monkeys that died in 10 zoos and private breeder in Brazil was published [Epiphanio et al, , , , 2003].…”

The aim of this study was to identify risk factors associated with prevalence of Toxoplasma gondii infection in captive capuchin monkeys at a facility in the northeastern Brazil. Serum samples from 116 bearded capuchin (Sapajus libidinosus), nine blonde capuchin (Sapajus flavius), five black-capped capuchin (Sapajus apella), and four capuchin monkeys (Sapajus spp.) were tested for T. gondii antibodies using the modified agglutination test (MAT, cut-off ≥25); antibodies were found in 85.3% (99/116) of S. libidinosus, 55.6% (5/9) of S. flavius, 80.0% (4/5) of S. apella, and 75.0% (3/4) of S. spp. The risk factors associated with T. gondii seropositivity were ingestion of raw meat [OR = 4.13 (1.26; 13.50)] and old age [OR = 4.90 (1.70; 14.13)]. Results indicate a very high T. gondii seropositivity in these primate populations. To minimize exposure to T. gondii raw meat should not be fed to these animals.
