“…Contact with dogs did not affect T. canis seropositivity, as it was 72.4% in those with contact and 65.5% in those without. Similar figures of 60%, 62%, 66%, and 73.6% have been reported in studies from Brazil and Ghana on T. canis infection and its association with having pet dogs 23 , 25 , 27 . However, a study in rural Turkey found a significant association between having dogs at home and anti- T. canis antibodies 28 .…”

“…The seroprevalence rate for T. canis was 71.8%. Similar rates have been observed in other regions in Brazil (52% and 65.4%) 23 , while seropositivity in other countries has been reported to range from 12% to 86% 10 , 24 , 25 . These differences in seroprevalence are attributable to various reasons, such as location, sample size, and age of the study population, as well as the diagnostic tests used.…”

Due to the growing population of pets, especially homeless dogs and cats, zoonoses still represent a significant public health problem. Toxoplasma gondii and Toxocara spp. are epidemiologically important zoonotic agents as they are etiological factors of human toxoplasmosis and toxocariasis, respectively. These parasites remain neglected even though they are substantially prevalent in rural areas. The aim of this study was to investigate T. gondii and T. canis seroprevalence and risk factors of seropositivity in a rural population in Pelotas municipality, Brazil. The study participants (n=344) were patients of a Basic Healthcare Unit (BHU) located in Cerrito Alegre. Blood samples were collected and tested for T. gondii antibodies by indirect immunofluorescence and T. canis antibodies by an indirect ELISA that targets an excreted-secreted antigen (TES). T. gondii seropositivity was 53.2%, with higher titers (1:256 - 1:1,024) in individuals who habitually eat pork, beef, or chicken, while T. canis seropositivity was 71.8% and concomitant T. gondii and T. canis seropositivity was 38.3%. Among the seropositivity risk factors assessed, only habitual undercooked meat consumption was significant (p = 0.046; OR = 3.7) for T. gondii and none of them were associated with T. canis seropositivity. Both parasites have a high prevalence in rural areas, which reinforces the need to invest in rural community education and health.

“…Epidemiological studies have shown that toxocariasis is 1 of the most common helminthic diseases in the world [ 3 , 10 , 11 ]. The worldwide prevalence of toxocariasis has been reported as 2–5% in urban areas, 15–20% in semi-rural areas and 35–42% in rural areas [ 2 ].…”

ObjectivesThe present study was performed to determine the seroprevalence of Toxocara in children ≤ 10 years old, from rural and urban areas of Ilam.MethodsSerum samples from 383 children ≤ 10 years old, were selected randomly from rural and urban areas of Ilam province and surveyed using enzyme-linked immunosorbent assays.ResultsThe total rate of infection with Toxocara was 22% (31% with a history of contact with dogs and cats, and 14% without a history of contact). Of those infected, 23% were male and 18% were female, 36% lived a rural life and 20% had an urban life. A significant correlation was found between the incidence of disease, and urban and rural life, as well as exposure to dogs and cats. There was no correlation between prevalence and gender or age.ConclusionGiven the high prevalence of infection with Toxocara amongst children in Ilam province, preventive work in the community such as education in risk management and periodic treatment with anti-parasitic drugs and elimination of stray dogs and cats is an appropriate measure.

“…Toxocara canis antibodies have been detected in people across Africa. For instance, two previous studies conducted in preschool children aged between 9 months to 5 years old in Nigeria and in children aged 1-15 years old in Ghana detected Toxocara canis antibodies in 37.3% and 53.5% of the study children, respectively [35,36]. Further, one study conducted in various groups of professionals in Egypt detected anti-T. canis antibodies in 24% of the professionals [37].…”

Background: Canine helminthiases pose a public health risk to humans and livestock; however, the prevalence of canine helminthiases in Rwanda is unknown. This study aimed to determine the prevalence of canine helminthiases and to identify the risk factors of such infections in Kigali, the capital city of Rwanda. A cross-sectional study involved 93 dogs selected across Kigali city. Faecal samples were collected from apparently healthy dogs and helminth eggs were identified and quantified under microscope using McMaster technique. Risk factors for canine helminthiases were analysed by multivariable binary logistic regression analysis.Results: The overall prevalence of intestinal helminthiases in dogs was 39.8% ±5.08 (α=0.05). The most prevalent species was Ancylostoma spp with 32.3% ± 4.85 (30/93). About 38.7% and 3.4% (n= 31) of dogs suffering from ancylostomosis and/or toxocarosis had high egg counts per gram (EPG) of faeces (≥ 550) each. Approximately 97.3% (36/37) of dogs infected with helminths had mono-infection. Logistic regression analysis showed that dog's age (1 to 2. 5 years old and at least 5 years old) and location (Gasabo and Kicukiro) were significantly associated with the prevalence of canine helminthiases. The adjusted odds ratio (AOR) of dogs suffering from helminthiases was more than 61% lower in dogs dewormed once to twice a year compared to those who were never dewormed. In addition, the AOR was more than 5 times higher for dogs fed on raw animal origin supplements, leftovers from family food and restaurants compared to those who ate food prepared for them. The AOR was also more than 8 times higher for dogs that ate leftovers from household food and scavenged compared to those who ate food prepared for them. Conclusions: All the identified helminths including Ancylostoma spp, Toxocara canis, and tapeworms are zoonotic and they pose a public health risk to humans. There is an urgent need of increasing the awareness among pet owners on the role of dogs in the transmission of zoonotic helminthiases to other animals and also to humans. Moreover, it is highly relevant to inform and to take effective control measures in dog populations.
