Babesia and Hepatozoon infections of dogs in a village of eastern Sudan were analyzed by using a single PCR and sequencing. Among 78 dogs, 5 were infected with Babesia canis rossi and 2 others were infected with B. canis vogeli. Thirty-three dogs were positive for Hepatozoon. Hepatozoon canis was detected by sequence analysis.
Thirty-three isolates of Bartonella spp., including 11 isolates not belonging to previously known species, were isolated from 66 Rattus norvegicus subjects trapped in the city of Marseille, France. Based on seven different gene sequences, the 11 isolates were assigned to Bartonella rattimassiliensis sp. nov. and Bartonella phoceensis sp. nov.
In 1996, an epidemic outbreak of visceral leishmaniasis (VL) started in Barbar el Fugara, a village in Gedarif State (eastern Sudan). From 1997 to 2000, regular epidemiological studies were carried out in the human population, as well as in mammals and sand flies. In symptomatic patients, 46/69 lymph node, 6/20 post kala-azar dermal leishmaniasis (PKDL) and(More)
The infection rates of Ehrlichia canis and related species in dogs in eastern Sudan were examined using molecular methods. Among 78 dogs examined, 63 (80.8%), 19 (24.4%), and 26 (33.3%) were positive for E. canis, Anaplasma platys, Mycoplasma haemocanis, and "Candidatus Mycoplasma haemoparvum," respectively. Among these, 30 dogs were single-positive: 25 for(More)
A cross sectional survey was carried out on a population of 82 rats (Rattus norvegicus and Rattus rattus alexandrinus) trapped in Marseille. The main histopathological finding was the presence of adults or eggs of Capillaria hepatica in 44% of the animals. 21% were found with fleas (Xenopsylla cheopis). There was no evidence of trichinosis in any of the(More)
OBJECTIVE To correlate the presence of different Bartonella species in the blood of a stray cat population trapped on a French military base with specific antibodies and species detected in cat fleas. METHODS The prevalence of Bartonella bacteremia was investigated in 61 cats by plating frozen whole blood on blood agar plates. Identification of isolates(More)
Visceral leishmaniasis (VL) is an acute public-health problem in Sudan. Between 1997 and 2000, four, brief entomological surveys were carried out in Barbar El Fugarra, a village in the state of Gedaref, in the Atbara-River area of eastern Sudan. Between 1996 and 1999, 658 cases of VL occurred among the village's population of about 4000. CDC miniature(More)
Our objective was to evaluate the efficacy of fipronil for the prevention of Ehrlichia canis transmission to dogs by Rhipicephalus sanguineus in two endemic areas situated in Africa (Dakar and Djibouti). We carried out controlled trials in kennels for 1 year on 248 dogs, mainly police dogs and military working dogs. Eight groups were studied in a(More)
A serological survey was carried out on 429 dogs belonging to the French military in France, French Guyana, Martinique, Senegal and the Ivory Coast. Serology against phase I and II antigens of Coxiella burnetii, the intracellular zoonotic bacterium was performed using indirect immunofluorescence techniques. Specific antibodies were found in dogs from France(More)
