Tiques et maladies à tiques : biologie, écologie évolutive, épidémiologie by Albert Agoulon( )

1 edition published in 2017 in French and held by 113 WorldCat member libraries worldwide

Présentes dans tous les écosystèmes, les tiques sont parmi les plus anciens arthropodes apparus sur Terre, exploitant leurs hôtes bien avant l'apparition de l'homme. Hématophages, elles sont responsables chez leurs hôtes d'une grande diversité de maladies, que ce soit par spoliation sanguine ou par transmission vectorielle de virus, de bactéries ou de parasites. Leur présence accrue dans l'environnement est à l'origine de nombreux cas d'encéphalites, de borrélioses de Lyme, de fièvres récurrentes, de babésioses ... Ainsi, les infestations par les tiques et les maladies qu'elles transmettent constituent un véritable problème de santé pour l'homme et pour les animaux domestiques, tant en zone tropicale que tempérée. Pour dresser un état des connaissances complet sur les tiques, cet ouvrage collectif adopte une approche pluridisciplinaire. Il décrit la systématique et l'évolution, la biologie et l'écologie des tiques ainsi que les relations complexes qu'elles entretiennent avec leur hôte. Les agents de maladies infectieuses transmis, les modes de transmission, les méthodes de prévention des risques ainsi qu'un état des lieux sur la lutte contre les tiques sont également présentés. Rédigé dans un langage accessible, ce livre constitue une référence actualisée sur un thème devenu un important enjeu de santé humaine et animale. Il est destiné aux étudiants, aux chercheurs, aux médecins et vétérinaires ainsi qu'aux autorités de santé

Etude des cycles épidémiologiques d'Anaplasma phagocytophilum en France : apport des approches de caractérisation génétique by Amélie Pierrette Chastagner( )

1 edition published in 2014 in French and held by 1 WorldCat member library worldwide

A. phagocytophilum, a tick-borne bacterium, is responsible of the granulocytic anaplasmosis, an emerging disease that infects a large range of mammals including humans. Currently, the description of the epidemiological cycles of this bacterium is incomplete. The objective of this thesis was to characterize the genetic diversity of A. phagocytophilum in different host species to determine those involved in the same epidemiological cycle. First, we characterized the genetic diversity of A. phagocytophilum in sick domestic animals with a MLSA. We identified three groups of genotypes infecting cattle, including one group shared with horses and dogs, and another shared with roe deer. Then, we investigated what species of ticks can transmit the bacteria, and what wild mammals could be reservoirs. In Camargue, a genotype with high zoonotic potential was identified in five species of ticks of the genus Rhipicephalus, Dermacentor and Hyalomma. The prevalence in French rodents suggests that they may be reservoir hosts, but the presence of genotypes infecting cattle in rodents must be checked. Finally, comparing the bacterial genotypes in ticks and roe deer by 454 sequencing, showed that the contribution of the roe deer to tick infection was low in the site of “Vallons de Gascogne”. The absence of infected rodents in this location suggests that other reservoir mammals are present. This study demonstrates the complexity of the A. phagocytophilum cycle and the contribution of molecular tools
Interactions multipartites entre communautés symbiotiques, pathogènes et vecteurs : le système vectoriel bactéries, endosymbiotiques, virus chikungunya, moustiques aedes by Karima Zouache( )

1 edition published in 2010 in French and held by 1 WorldCat member library worldwide

Aedes albopictus et Aedes aegypti sont des moustiques vecteurs d'arbovirus tels que le virus de la dengue et le virus du chikungunya. En plus des virus transmis, les moustiques hébergent également des bactéries dont certaines affectent la biologie des hôtes. Par exemple, la bactérie Wolbachia infecte naturellement Aedes albopictus. Comme chez la plupart des insectes, cette bactérie est un parasite qui manipule la reproduction du moustique et peut également interagir avec certains pathogènes, modifiant ainsi la transmission du pathogène par le moustique hôte. Hors Wolbachia, peu d'études ont été consacrées à l'étude des populations bactériennes hébergées par les moustiques du genre Aedes et aux interactions entre ces populations bactériennes et les arbovirus transmis. Dans ce contexte, le travail de cette thèse a consisté à caractériser la diversité des communautés bactériennes des moustiques du genre Aedes et à explorer l'interférence possible entre le compartiment bactérien et le virus chikungunya. L'utilisation de techniques telles que les isolements bactériens, l'amplification par PCR, la DGGE et l'hybridation in situ ont permis de détecter et localiser certaines bactéries présentes chez des populations naturelles et de laboratoires d'Aedes. Ces populations appartiennent aux Alpha, Beta et Gammaprotéobactéries ainsi qu'aux Firmicutes. L'étude de la dynamique des communautés bactériennes symbiotiques et de l'infection par le virus chikungunya chez Aedes albopictus par PCR quantitative et puces taxonomiques a révélé l'existence d'interactions entre les différents partenaires de ce système vectoriel
Mycobacterium ulcerans infection (Buruli ulcer) in French Guiana, South America, 1969-2013: an epidemiological study( )

1 edition published in 2017 in English and held by 1 WorldCat member library worldwide

Background: Mycobacterium ulcerans infection is the third most common mycobacterial disease in the world after tuberculosis and leprosy. To date, transmission pathways from its environmental reservoir to humans are still unknown. In South America, French Guiana has the highest reported number of M ulcerans infections across the continent. This empirical study aimed to characterise the epidemiology of M ulcerans infection in French Guiana between 1969 and 2013. Methods: Data were collected prospectively mainly by two dermatologists at Cayenne Hospital's dermatology department between Jan 1, 1969, and Dec 31, 2013, for age, date of diagnosis, sex, residence, location of the lesion, type of lesion, associated symptoms, and diagnostic method (smear, culture, PCR, or histology) for all confirmed and suspected cases of M ulcerans . We obtained population data from censuses. We calculated mean M ulcerans infection incidences, presented as the number of cases per 100 000 person-years. Findings: 245 patients with M ulcerans infections were reported at Cayenne Hospital's dermatology department during the study period. M ulcerans infection incidence decreased over time, from 6·07 infections per 100 000 person-years (95% CI 4·46-7·67) in 1969-83 to 4·77 infections per 100 000 person-years (3·75-5·79) in 1984-98 and to 3·49 infections per 100 000 person-years (2·83-4·16) in 1999-2013. The proportion of children with infections also declined with time, from 42 (76%) of 55 patients in 1969-83 to 26 (31%) of 84 in 1984-98 and to 22 (21%) of 106 in 1999-2013. Most cases occurred in coastal areas surrounded by marshy savannah (incidence of 21·08 per 100 000 person-years in Sinnamary and 21·18 per 100 000 person-years in Mana). Lesions mainly affected limbs (lower limbs 161 [66%] patients; upper limbs 60 [24%] patients). We diagnosed no bone infections. Interpretation: The decrease of M ulcerans infection incidence and the proportion of children with infections over a 45 year period in this ultra-peripheral French territory might have been mostly driven by improving living conditions, prophylactic recommendations, and access to health care.
