The estimated incidence of UTI in our country is currently unknown. However, it is believed that this phenomenon is repeated in other developing countries.1 UTIs represent more than 100,000 hospitalizations per year in countries such as the United States, most of them due to complicated UTIs. Likewise, they represent approximately 40% of all nosocomial infections, which in most cases, are associated with placement of bladder catheters.1,2","PeriodicalId":91326,"journal":{"name":"Journal of microbiology & experimentation","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-04-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47041817","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}

More than 1.5 million cases of Leishmaniasis occur annually, of which 0.7–1.2 million are CL.1 Since CL was First described in Saudi Arabia (1976) by Morsy and Shoura and until (1996) Saudi Arabia was among the top 10 endemic countries globally.3 Currently Saudi Arabia is considered the fourth most endemic area in western Asia.4 The total number of reported incidence of CL in Saudi Arabia from 2006-2015 was 24,970 of which 2100 were recorded from Hail, which was the most consistent endemic region throughout the study with high incidence (>10 cases/100,000 population).

Through the interruption of this habitat by construction sites and emerging closer neighborhoods or villages, the transmission through sand fly bites increases among human inhabitants of these regions.5","PeriodicalId":91326,"journal":{"name":"Journal of microbiology & experimentation","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-03-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41557352","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}

Out of 40 samples obtained from the nasal cavity of the female students, a total of 9 isolates of Staphylococcus aureus were confirmed. Based on the biochemical tests, they were all Gram-positive cocci in clusters, catalase positive, coagulase positive and DNase positive.

Pickup et al.,9 also found Map in biofilm on Nantgaredig Bridge spanning the River Tywi in Wales and on an abstraction site grating. These reports demonstrate the possibility that Map being a Mycobacterium, could also form biofilm since previous work has shown its occurrence and persistence in water treatment operations.10‒13 Furthermore, the presence of organic sediment, with which mycobacterial species are associated as part of biofilm microflora, is an important feature in their persistence in lakes and rivers.14,15 However, in the case of water treatment systems, the schmutzdecke which is a meshwork of biologically active matter atop a slow sand filter bed, may either promote or suppress the growth of mycobacteria. Even though to the authors knowledge, biofilm formation by Map in the water environment has not been reported, it does have a lipid cell wall16 which contains on the cell envelope glycopeptidolipids (GPLs) which convey hydrophobic properties.17 This makes Map potentially capable of attaching to a suitable surface as GPLs are directly or indirectly required for colonisation of some surfaces.18 In this study, biofilm formation by 2 environmental and 1 human isolates of Map was investigated under laboratory conditions, to establish their ability to form biofilm, in particular, in the water environment where schmutzdecke may provide proliferative support to environmentally persistent microorganisms for their consequential access to domestic water outlets.","PeriodicalId":91326,"journal":{"name":"Journal of microbiology & experimentation","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-03-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48436870","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}
