“…Thus, taking into account the growth of the dog and cat population in Thailand (OIE, 2019), the particularly close contact between these species and humans in the study area (Savvides, 2013;Toukhsati et al, 2015) and the seroprevalence detected in this study, outdoor cats and dogs in Bangkok should be considered as hosts with a possibly significant epidemiological role in the maintenance of T. gondii. Regarding other Asian countries, a study carried out in China showed higher seroprevalences (8.2-30.9%) in dogs using the same technique (MAT) on a similar sample size (Dubey et al, 2020b); in cats, slightly higher seroprevalences have also been described using MAT on a similar sample size in China (19.3-24.4%) and much higher seroprevalence has been reported in Qatar (82%) (Dubey et al, 2020a).…”

“…In fact, eating raw or undercooked meat have, respectively, 1.2-1.3 times the risk and 1.7-3.0 times the odds of T. gondii infection compared to those who thoroughly cook meat [22]. The geographical distribution map of epidemiology of toxoplasmosis in humans in China is illustrated in Fig.…”

Background: Toxoplasma gondii (T. gondii) is an important foodborne zoonotic parasite with respect to abortion, intracranial calcifications, congenital hydrocephalus, retinochoroiditis, and toxoplasmic encephalitis in severely immunosuppressed individuals. Undercooked/raw meat containing cyst-stage bradyzoites and contaminated pets are presumed to constitute a major source of human infection. Although many seroprevalence studies have been performed in humans and different animal species in China, data on the geospatial distribution of toxoplasmosis prevalence are extremely scarce. The aim of the present study was to investigate the prevalence and geospatial distribution of toxoplasmosis among livestock, pets and humans in China using geographic information system (GIS) for the prevention and control of toxoplasmosis.Methods: This article is based on the data from PubMed, China National Knowledge Infrastructure (CNKI) and Baidu Scholar databases from 1984 up to 2020 regarding prevalence data of toxoplasmosis among livestock (sheep and goats, swines, cattle and yaks), pets (cats, dogs) and humans in China. Geospatial distribution of the prevalence of toxoplasmosis in these hosts was performed using the GIS visualization techniques.Results: Analysis revealed wide geospatial variation of toxoplasmosis in China. The estimated pooled seroprevalence of T. gondii was ranged from 3.98% to 43.02% among sheep and goats in China, 0.75% to 30.34% in cattle and yaks, 10.45% to 66.47% in swines, 2.50% to 60.00% in cats, 0.56% to 27.65% in dogs, and 0.72% to 23.41% in humans. The higher seroprevalences of T. gondii were observed in districts Chongqing, Zhejiang and Beijing in sheep and goats. The infection rates of T. gondii in cattle and yaks were higher in districts Guizhou, Zhejiang and Chongqing. Moreover, the swines from districts Chongqing and Guizhou were also most severely infected with T. gondii. In cats, districts Shanxi, Hebei and Yunnan had higher seroprevalences of T. gondii and, the infections among dogs were higher in districts Yunnan and Hebei as well. Furthermore, higher infection pressure of T. gondii exists in districts Taiwan and Tibet in humans.Conclusion: The present study indicated that the infection with T. gondii was widely spread in China, with a wide range of variation. The investigation of T. gondii infection in livestock, pets and humans can be useful for assessing T. gondii environmental contamination and the risk for public health. Certain measures can be taken to prevent the prevalence of T. gondii infection in China, such as strengthening the management of livestock farms, keeping the barn clean, preventing feline excreta from polluting environment, using filtered water or water boiling, wearing gloves when handling raw meat and improving the practice of good hand hygiene.

“…Domestic dogs, as well as other mammals, including humans, and birds, are T. gondii intermediate hosts. The diet is an important factor for infection by T. gondii in domestic dogs and cats [25,29]. The supply of leftovers, homemade food, and offal for these animals, especially dogs, may indicate possible sources of infection shared with humans.…”

Toxoplasma gondii in domiciled dogs and cats in urban areas of Brazil: risk factors and spatial distribution

et al. 2021

View full text Add to dashboard Cite

Toxoplasma gondii is a highly prevalent zoonotic parasite in Brazil capable of infecting mammals and birds. The increase in the urban populations of pets and the narrowing of the human–animal relationship can facilitate the transmission of important public health zoonoses, such as toxoplasmosis. This study aimed to evaluate the frequency and spatial distribution of T. gondii infection and its risk factors in domiciled dogs and cats attended at the Jorge Vaitsman Institute, Rio de Janeiro. Serum samples from 400 dogs and 272 cats were evaluated by an indirect fluorescent antibody test (IFAT) for IgG anti-T. gondii antibodies. Epidemiological questionnaires were used to interview the animals’ owners to identify risk factors for infection. Of the total, 34% (136/400) of dogs and 8.1% (22/272) of cats had anti-T. gondii antibodies. Breed (OR: 2.10–95%, CI 1.27–3.46) was a risk factor for dogs, while sex (OR: 3.40–95%, CI 1.10–10.52) and homemade food consumption (OR: 8.49–95%, CI 2.48–29.05) were risk factors for cats. Offal consumption was considered a risk factor for both species evaluated (OR: 2.74–95%, CI 1.38–5.43 for dogs; OR: 7.66–95%, CI 1.24–47.29 for cats). The spatial analysis showed that T. gondii seropositive animals were widely distributed in the metropolitan region of Rio de Janeiro state, with a concentration observed mainly in the west and north zones of Rio de Janeiro city. The results emphasize the importance of adopting prophylactic measures to control T. gondii transmission in domiciled dogs and cats in Rio de Janeiro, contributing positively to public health.
