BACKGROUND Dogs are the most common pet animals worldwide. They may harbour a wide range of parasites with zoonotic potential, thus causing a health risk to humans. In Nigeria, epidemiological knowledge on these parasites is limited. METHODS In a community-based study, we examined 396 dogs in urban and rural areas of Ilorin (Kwara State, Central Nigeria)(More)
Epidermal parasitic skin diseases (EPSD) are a heterogeneous category of infectious diseases in which parasite-host interactions are confined to the upper layer of the skin. The six major EPSD are scabies, pediculosis (capitis, corporis and pubis), tungiasis and hookworm-related cutaneous larva migrans. We summarize the current knowledge on EPSD and show(More)
Because topical compounds based on insecticidal chemicals are the mainstay of head lice treatment, but resistance is increasing, alternatives, such as herbs and oils are being sold to treat head lice. To test a commercial shampoo based on seed extract of Azadirachta indica (neem tree) for its in vitro effect, head lice (n=17) were collected from school(More)
Tungiasis is caused by infestation with the sand flea (Tunga penetrans). This ectoparasitosis is endemic in economically depressed communities in South American and African countries. Tungiasis is usually considered an entomologic nuisance and does not receive much attention from healthcare professionals. During a study on tungiasis-related disease in an(More)
BACKGROUND Brazil reports almost 80% of all leprosy cases in the Americas. This study aimed to identify socioeconomic, environmental, and behavioural factors associated with risk of leprosy occurrence in the endemic North-eastern region. METHODS A case-control study in four municipalities. CASES cases of leprosy diagnosed in the previous 2 years, with(More)
Chagas disease is a major public health problem in Brazil and Latin America. During the last years, it has become an emerging problem in North America and Europe due to increasing international migration. Here we describe the prevalence of Chagas disease in Brazil through a systematic review. We searched national and international electronic databases, grey(More)
Pediculosis capitis is a common disease in industrialized countries, but there are also areas in sub-Saharan Africa where head lice infestations are highly endemic. However, there are no data available from the African continent on the accuracy of head lice diagnosis made by affected individuals. We performed a door-to-door survey in Skanko village (Kwara(More)
Two waterborne outbreaks of toxoplasmosis have been described recently in southern Brazil. We present data from a community-based study of pregnant women in northeastern Brazil. Consumption of homemade ice was the only variable associated with seropositivity (adjusted odds ratio, 3.1, 95% confidence interval, 1.53-6.24). Our results suggest that water is a(More)
In this study we describe the dental status and oral hygiene practices in institutionalized older people and identify factors associated with poor dental status. A cross-sectional study was performed in a nursing home in Fortaleza, the capital of Ceará State (northeast Brazil). The number of decayed, missing, and filled teeth (DMFT) was assessed in the(More)
BACKGROUND Infestation with the human head louse (Pediculus humanus capitis) occurs worldwide. Existing treatment options are limited, and reports of resistance to commonly used pediculicides have been increasing. In this trial we assessed the efficacy of a product containing a high (92%) concentration of the silicone oil dimeticone (identical in(More)
