Abstract
Recent studies of Echinococcus granulosus molecular strain typing have enabled a better understanding of the transmission cycle of cystic echinococcosis. There have been many publications in this area but there is a need for the evaluation of these tools. We have attempted to respond to this need in our study, which assessed 8 DNA fragments of 40 E. granulosus cysts from North Africa. Parasitological material was collected from 5 types of intermediate hosts, in 5 different countries. The primers chosen to amplify DNA targets were defined either in nuclear DNA, or in mitochondrial DNA. After amplification, PCR products were sequenced. The sequences obtained were aligned and comparisons were made within the group and with GenBank sequences. Whether the target was nuclear or mitochondrial, the same 2 main groups of genotypes were found. The first one, the 'sheep' strain, was found in the human, sheep and cattle samples collected in North Africa. The second one, the 'camel' strain, was found in the camel cysts and cattle and human cysts from Mauritania. These findings further confirm the congruence of the data given by the nuclear and the mitochondrial genome.

Abstract
BACKGROUND Recent studies in France have shown that Absidia corymbifera and, to a lesser degree Eurotium amstelodami and Wallemia sebi, play a role in farmer's lung disease (FLD), but that Saccharopolyspora rectivirgula, classically incriminated, does not. Little is known about farmers' reactions to these fungi or the circumstances which lead to exposure. AIMS To investigate the conditions which favour the development of these microorganisms in hay and to analyse the relation between their concentration and the risk of occurrence of FLD. METHODS Sequential microbiological analyses of each batch of hay stored in 10 farms at risk for FLD and a serological survey of 10 farmers (five with a past history of FLD). RESULTS Exposure to microorganisms varied widely according to farms and periods. These microorganisms usually reached a peak in January and proliferated when harvesting conditions favoured excessive humidity in hay (rain during harvest, soil in the hay). Three of the five FLD patients presented with FLD respiratory recurrence and positive serology for A corymbifera during the winter (2000-01), after exposure to a significantly higher amount of A corymbifera than other farmers. Similar, but less significant, results were found for E amstelodami exposure, but not with W sebi. CONCLUSIONS Results contribute to confirming A corymbifera as a major aetiological agent of FLD in Doubs, and encourage further studies with a view to implementing preventive measures.

Abstract
In Algeria, cystic echinococcosis (CE) is a serious economic and public health problem. The common sheep/dog cycle is usually considered as the major source of human contamination. But to date the main strain of Echinococcus granulosus involved in the human contamination and the role of other hosts are still unknown. This paper reports an original work performed in northern Algeria combining field observations and molecular analysis. In a first step, examination of 6237 carcasses in slaughterhouses showed high infection and fertility rates in cattle and dromedaries. Then, in a second step, we used a molecular biology approach to identify the E. granulosus strain(s) involved. Forty-six samples from various origins were collected. They were analysed using comparison of PCR-amplified DNA sequences with one genomic (BG 1/3) and two mitochondrial (COI and NDI) targets. Results show the presence of a "sheep" strain of E. granulosus in North Algeria circulating between cattle and ovines and infectious to humans, whereas in South Algeria, a "camel" strain and a "sheep" strain were found to circulate in camels and in sheep, respectively. This study also reports an ambiguous genotype which resembled the "sheep" strain genotype (Gl) on the basis of the partial COI gene sequence, whereas on the basis of the partial NDI gene sequence, it was similar either to the "sheep" strain (Gl) or to the "camel" strain (G6). Besides its basic interest, our study confirms the role of other hosts (mainly cattle) in leading to transmission to humans and suggests that control measures should not only target sheep.

Abstract
Mauritania lies between West-Central Africa where human cystic echinococcosis (CE) is considered extremely rare and West Maghreb where CE accounts for a real public health problem. Until 1992, Mauritania was considered as human CE-free even through CE seemed well known in livestock. In 1992, the introduction of ultrasonography led to the diagnosis of the first human CE cases. In 1997, a veterinary study revealed that dogs living around Nouakchott were commonly infected by Echinococcus granulosus. To assess E. granulosus transmission and to identify the most relevant animal reservoir responsible for human CE emerging in Mauritania, a simultaneous eco-epidemiological and molecular biology approach was performed. The fieldwork included sample collection and investigation of relationship between intermediate hosts, definitive hosts and humans. Typing of E. granulosus strains was performed using comparison of polymerase chain reaction (PCR)-amplified DNA sequences with one nuclear (BG 1/3) and 2 mitochondrial (COI, NDI) targets. Results show that the 'camel' strain is actually infectious to humans and circulates between intermediate hosts including camels and cattle. It is suggested that preventive measures at slaughtering places could reduce human contamination.

Abstract
Leishmanioses are a group of infections caused by the protozoa Leishmania. Humans are infected by female sandfly bites. Leishmaniosis is found in Mediterranean Europe, America, Africa and Asia. Various clinical expressions are possible: visceral (kala-azar) or cutaneous (Old world cutaneous leishmaniosis). In Mediterranean Europe, visceral leishmaniosis with the classical triad, splenomegaly, pallor, fever, was traditionally a childhood disease whereas today the disease with atypical clinical expressions strikes immunocompromised patients. In these atypical forms of visceral leishmaniosis, diagnosis and treatment are particularly difficult. Leishmania-DNA research using polymerase chain reaction is often necessary to perform the diagnosis, and lipid-associated formulations of amphotericin B, rapidly effective and well-tolerated in patients without immunodeficiency, do not prevent recurrences in immunocompromised patients.

Abstract
Farmer's lung disease (FLD) is common in the east of France. In the absence of the primary recognized FLD agent, Saccharopolyspora rectivirgula, its etiology remains unknown. A prospective case-control study was performed to find the etiology of FLD in this area. Eleven patients were matched with 11 healthy control farmers. Twenty-two urban subjects constituted the nonexposed control group. Microorganisms from cowshed air and fodder were identified and counted. The antigens of the microorganisms most frequently isolated at the 22 farms were used for serological tests. Farms of patients with FLD contained more Absidia corymbifera than those of healthy farmers (p < 0.05 in air, p < 0.01 in fodder). Electrosyneresis, performed with A. corymbifera somatic antigen, differentiated 9 of 11 patients with FLD from control subjects (p < 0.01). Other significant results were obtained with Eurotium amstelodami (p < 0.01) and Wallemia sebi (p < 0.05). In contrast, no significant results were obtained with the other seven antigens tested, including S. rectivirgula. Absidia corymbifera and, to a lesser degree, W. sebi or E. amstelodami are likely to be the main causes of FLD in this area. Modifications in working conditions over time could explain the emergence of these new contributing etiologies.
