Fast identification of C. krusei as an infectious agent will decrease the risk of choice of not correct therapy. The aim of the present work was to study the epidemiology of Candida krusei infections during 10 years. We also attempt to study the phylogeny of these isolates by PCR- RFLP. Methods: Two hundred five cases of C. krusei candidiasis were referred to laboratory of parasitology mycology, UH Habib Bourguiba of Sfax-Tunisia during 10 years (2006 to 2016). Identification of our strains was performed by conventional methods and by PCR-ITS amplification followed by a digestion with three restriction enzymes MspI, HinfI and HincII. Result: The mean frequency of cases of C. krusei candidiasis was 17.08 per year. Invasive infection represented 10.24%. The superficial infections with C. krusei represented 89.76% of cases. Analysis of the phylogeny tree allowed us to deduce that there is a great diversity in C. krusei strains. No particular genotype has been associated with the sampling site, or department or year of infection. We noted that patient P4 was hosted by three strains with the same genotype. Conclusion: The modification in epidemiology of candidiasis emphasizes the necessity to monitor local incidence, species distribution and susceptibility in order to optimize therapy and outcome. Molecular methods are essential for correct identification of the Candida species in order to obtain clues regarding the source of infection and to apply the correct therapy for the infected individual.","PeriodicalId":91631,"journal":{"name":"Virology & mycology : infectious diseases","volume":"07 1","pages":"1-6"},"PeriodicalIF":0.0,"publicationDate":"2018-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"70457471","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}

Because the use of an antimicrobial inevitably leads to the emergence of resistance, a constant search for new molecules is required with which to deal with outbreaks and decrease the infection rate [2]. This indiscriminate use of anti-infectives both in humans and in agriculture makes possible the appearance of multidrug-resistant strains (MDR). Between them the most reported MDR microorganisms are methicillin-resistant Staphylococcus aureus (MRSA), vancomycin-resistant enterococci (VRE), Escherichia coli and Pseudomonas aeruginosa resistant to fluoroquinolones, Klebsiella pneumonia resistant to ceftazidime, Acinetobacter baumannii, and isoniazid-rifampicin resistant Mycobacterium tuberculosis [3]. Additionally, this very serious public health problem is complicated by the lack of availability and research into new active medicines against MDR microorganisms [4]. So several initiatives have been proposed as 10 × 20 initiative from Infectious Disease Society of America that propose the global union of several leading institutions in order to develop 10 new antimicrobial drugs by 2020 [5,6]. In this order of ideas, to assume this great challenge makes it necessary to overcome the mechanisms of microbial defense that induce resistance as biofilms that allows the survival of microorganisms in their interior through chemically induced environmental changes that favor their adaptation [7-9]. Also, research into new antibiotics has decreased because they have a lower rate of return than drugs used to treat chronic diseases [10,11].","PeriodicalId":91631,"journal":{"name":"Virology & mycology : infectious diseases","volume":"7 1","pages":"1-3"},"PeriodicalIF":0.0,"publicationDate":"2018-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"70457003","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}

Available literature from the years 1900 to 2018 were assessed and compiled. Previous analyses on the partial structural envelope as well as the non-structural proteins gene sequences suggests the occurrence of ZIKV strains ancestor erstwhile in the beginning of 1900s in Uganda. Infection with the virus was also first reported in Uganda since 1947. It gradually distributed to different countries in the world until the present 2018. It was found that ZIKV has multifactorial health challenges from several corners. Its epidemiology has wide reservoirs, susceptible and vector hosts, and different mode of transmission. The potential mechanisms of epidemic occurrences are viral evolution changes in mosquito, presence of human viremia and immunity in endemic exposures, and stochastic introduction to new areas. Moreover, climate change which disrupts health security and sociology-economy favors vector mosquito make ZIKV adaptation and causes global emerging epidemics. Presence of global travel with possibility of human-to-human transmission, urban area preference of the vector mosquito, and climate change adaptation of both the virus and the vector are core current risk for the epidemic. Presence of crossreactors, absence of both therapeutic drug and vaccine (the only promising future vaccine being ZIKV sub-unit recombinant biotechnology) were exacerbating the risk of Zika infections. The present sole preventive strategy is vector control. Therefore, defined and prioritized research on the epidemiology, diagnostic techniques, therapeutic drug and preventive vaccine development are recommended. Burst feed transmission should be checked. Capacity building on diagnostic laboratories and risk communication are relevant for developing countries.","PeriodicalId":91631,"journal":{"name":"Virology & mycology : infectious diseases","volume":"7 1","pages":"1-12"},"PeriodicalIF":0.0,"publicationDate":"2018-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.4172/2161-0517.1000179","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"70457032","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}

Determining how and when TMV first emerged in China, its current evolutionary rate, diffusion pathways, spatial and plant host distributions, can help minimize the risk associated with mosaic disease (MD). Here, 110 TMV Coat Protein (CP) gene sequences sampled from 12 distinct plant hosts between 1997 and 2015 from 18 geographical locations within China (14 Provinces, two Municipalities and two Autonomous regions) were used in a probabilistic Bayesian inferential framework implemented in BEAST v1.8.1 to reconstruct TMV's evolutionary history from emergence to spatiotemporal diffusion. This entailed estimating and inferring; (a) the time when and location where TMV's most recent common ancestor (MRCA) emerged, (b) the evolutionary rate, (c) diffusion pathways, (d) levels of genetic diversity and, (e) phylogenetic relationships amongst viruses. This study infers that TMV emerged around 1924 (95% HPD; 1860 to 1971) in Henan province. Its mean nucleotide substitution rate of 1.09 × 10-3 is marginally higher than previous TMV and Tobamovirus species rates. TMV's current wide spatial and plant host distribution across China is due largely to (i) utilization of 15 Bayes factor supported diffusion pathways, 60% of which were outward bound viral movements from Yunnan province to proximal and distant sampling locations and (ii) a growing shift toward cost-efficient tobacco crop substitution alternatives and adoption of a mixed-crop farming system. These analyses also suggest that Yunnan province is most probably both a source rather than a sink of TMV dispersal throughout China and a major thoroughfare of trans-China TMV movements. Finally, results also indicate that TMV populations exhibited both low effective population sizes and levels of genetic diversity, while individuals from distinct hosts were phylogenetically similar probably due to strong bottlenecks and purifying selection.","PeriodicalId":91631,"journal":{"name":"Virology & mycology : infectious diseases","volume":"6 1","pages":"1-10"},"PeriodicalIF":0.0,"publicationDate":"2017-12-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.4172/2161-0517.1000171","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45778659","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}
