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)
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)
Background. We assessed community knowledge, attitudes, and practices on malaria as well as acceptability to indoor residual spraying. Material and Methods. A cross-sectional survey was done in a community in Geita district (northwest Tanzania). Household heads (n = 366) were interviewed Results. Knowledge on malaria transmission, prevention, and treatment(More)
BACKGROUND Chagas' disease is an important neglected public health problem in many Latin American countries, but population-based epidemiological data are scarce. Here we present a nationwide analysis on Chagas-associated mortality, and risk factors for death from this disease. METHODOLOGY/PRINCIPAL FINDINGS We analyzed all death certificates of(More)
BACKGROUND Malaria, schistosomiasis and intestinal helminth infections are causes of high morbidity in most tropical parts of the world. Even though these infections often co-exist, most studies focus on individual diseases. In the present study, we investigated the prevalence of Plasmodium falciparum-malaria, intestinal schistosomiasis, soil-transmitted(More)
In Tanzania, the first cases of schistosomiasis were reported in the early 19th century. Since then, various studies have reported prevalences of up to 100% in some areas. However, for many years, there have been no sustainable control programmes and systematic data from observational and control studies are very limited in the public domain. To cover that(More)
Background: Data on ovicidal activity of pediculicides are essential to determine the efficacy of commercial products, and to define application schemes. We present an adaptation of historical methods for rearing head lice, and describe their development ex vivo. Methods: Adult head lice were collected and fed on volunteers to obtain fertile eggs of known(More)
