Acquiring knowledge about the biotypology of these mosquitoes is an essential step in any control strategy. Thus, the objective of this study is to draw up an inventory of the culicidian fauna in the Fez region (North-central part of Morocco) and to determine the physicochemical parameters influencing the production of mosquito larvae of aquatic habitats in this area. Mosquito larvae of the extant biotopes were sampled every two months between November 2015 and December 2016, by means of the \"dipping\" method. The physicochemical parameters of the various larval biotopes were collected six times during the year of follow-up. Mosquito species were identified using morphological criteria. The results were analyzed using ecological indices and the generalized linear model (Poisson model) on R software. The identification of the 1,122 mosquito larvae collected from the various studied breeding areas revealed the presence of 11 species belonging to two subfamilies (Culicinae and Anophelinae) and five genera (Anopheles, Culex, Culiseta, Aedes, and Uranotaenia). Anopheles were observed in small numbers in permanent, stagnant, and shallow habitats. The larvae of An. maculipennis s. l. (major vector of malaria in Morocco) were collected. Culex larvae, especially Cx. pipiens (the main vector of WNV in Morocco), were collected in the majority of the larval habitats and on the different types of environments. Two other species of Culex, which plays a significant role in the transmission of WNV, were also collected, particularly, Cx. perexiguus and Cx. theileri. The results found, via this first study of its kind at the regional level, also made it possible to update the list of Culicidae species reported in the Fez region. Four new species have been recorded: Aedes flavescens, Uranotaenia unguiculata, Culiseta longiareolata, and Culex perexiguus. The results of this study will contribute to the provision of information for entomological surveillance and to better plan and guide vector control activities at local and national levels.","PeriodicalId":9353,"journal":{"name":"Bulletin de la Societe de pathologie exotique","volume":"68 1","pages":"105-113"},"PeriodicalIF":0.0,"publicationDate":"2019-02-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84092898","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Samples were collected monthly from 13 stations within the watershed. The direct concentration method and the Ziehl-Neelsen technique were employed in the identification of these parasites. The physicochemical analysis showed that the water samples had a neutral pH (7.46±0.46), lowly mineralized (165.61±110.02μS/cm), moderately oxygenated (60.64 ± 17, 25%), present moderate organic pollution (2.85±2.49mg/l KMnO4). KMnO4) and low levels of orthophosphate (1.8±1.88 mg/l PO43-) and nitrates (2.47±5.06 mg/l NO3-). Biological analysis revealed the presence of Cryptosporidium spp. (143.98±203.35 oocysts/l), Isospora belli (88.47 ± 123.19 oocysts/l), Cyclospora cayetanensis (141.31±143.19 oocysts/l) and Sarcocystis hominis (76 ± 111.04 oocysts/l). The highest densities of these parasites were recorded at the Mufueh stream, situated in the periurban area. Meanwhile, the lowest densities were found in the urban area (Formuki, Mankon, Ayaba and Mezam streams). The dry season showed higher densities of oocysts (471.42±216.32 oocysts /l). Statistical analysis revealed a significant correlation (P ≤ 0.05) between the density of the organisms and the physico-chemical parameters such as pH, oxidability, dissolved oxygen and nitrates. Respecting basic hygienic rules as well as treating water before use would reduce the risk of contamination of the population.","PeriodicalId":9353,"journal":{"name":"Bulletin de la Societe de pathologie exotique","volume":"112 2 1","pages":"61-70"},"PeriodicalIF":0.0,"publicationDate":"2019-02-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"69372722","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the country seems to be experiencing a resurgence of the disease according to recent surveys at certain sentinel sites and data from various surveys. The aim of our study is to take stock of the evolution of the current epidemiological situation of onchocerciasis in Burkina Faso. For data collection, in addition to the scientific articles, we have used data from different epidemiological and entomological surveys conducted by the National Program for the Control of Neglected Tropical Diseases (PNLMTN) through its onchocerciasis elimination unit in Burkina Faso. Prior to implementation of the Onchocerciasis Control Program in West Africa (OCP), Burkina Faso had onchocerciasis prevalence between 60% and 80%. In 2002, the maximum prevalence dropped to 15%. However, in 2010 and 2011, epidemiological surveys indicated that some villages in the Comoé River basin had prevalence rate ranging from 0.7% to 71%. Thirteen (13) villages had prevalence rates above the tolerable threshold of 5%. Despite the implementation of the community-directed treatment with ivermectin (CDTI) since 2011, recent surveys show a tendency for a recrudescence of the disease in some sites, yet covered by the TIDC. This suggests that the elimination of onchocerciasis requires the integration of new control strategies. Thus, an essential condition for the elimination of onchocerciasis is the analysis of the situation in each focus in order to define the most cost-effective strategy for permanently interrupting the transmission of the parasite. National onchocerciasis elimination committees put in place will play a key role in determining the best strategy.</p>","PeriodicalId":9353,"journal":{"name":"Bulletin de la Societe de pathologie exotique","volume":"112 5","pages":"260-274"},"PeriodicalIF":0.0,"publicationDate":"2019-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"38436239","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
