A longitudinal malaria survey was undertaken in children under five in 5 villages of Katana Rural Health Zone in Kivu, East Zaire. During the year 1983, seasonal fluctuations ranging from 25 to 44% were observed in the parasitological index as well as concomitant variations from 5 to 18% in the splenic index. More malaria transmission seems to occur during(More)
A very reliable and productive technique for cloning of Plasmodium falciparum in vitro is proposed, as demonstrated by successive limiting dilution of suspensions of asexual erythrocytic forms of the NF 54 strain. The introduction and the study of reliable clones is of extreme importance for a better understanding of the behaviour of the parasite, also in(More)
Tropical bartonellosis is a highly fatal epidemic and endemic infectious disease that occurs throughout the communities of the Andes Mountains in South America. The disease is caused by the facultative intracellular bacteria, Bartonella bacilliformis. The emergence of bartonellosis in new geographic areas and an increase in the number of reported cases(More)
Plasmodium falciparum sensitivity to quinine in São Tomé was determined by in vivo and in vitro tests in 56 children with mild or cerebral malaria. Chloroquine sensitivity was assessed by in vitro tests in 105 parasitaemic asymptomatic children from the same community as the cases. The WHO standard methodology was used. No resistance to quinine was found by(More)
INTRODUCTION Since its first description in 1994, tubularized incised plate (TIP) technique has become the most commonly performed hypospadias procedure and involves incision of the urethral plate with subsequent tubularization. Glans wings are then developed to cover the neourethra, thereby creating a cosmetically appealing repair. In some distal(More)
