Professionals who are in constant contact with animals and their residues, in water supply, rice mill, slaughtering houses, hospital sanitary places, strawberry picking, construction works, agriculture working, forest working and food industry are at highest risk. Factors related to occupational, environmental, and recreational aspects and the presence of wild reservoirs of leptospirosis will be discussed in this concise review. Noticeably, lack of early identification, international travelling, skin wounds, sanitary and washing habitations after contact with animals, delay in treatment, and unhealthy behaviors of adolescents contribute to the disease. Hence, public education for people's awareness is essential. For instance, farmers, students, forest keepers, veterinary surgeons or veterinarians, and abattoir workers should take care by wearing cloth, such as long trousers and a long-sleeved shirt, and simple gloves to hinder the infection acquisition through skin. For people engaged in water sports, covering skin abrasions with waterproof dressings and wearing protective clothing can prevent disease transmission. However, there is no same control strategy applicable to all epidemiological wards universally. Furthermore, ecoepidemiological and cultural characteristics should be well recognized.

This study aimed to use nanoparticles and UVC radiation, which were considered in some previous laboratory studies. The contaminated water was entered into a photocatalytic reactor, and microbial removal efficiency of TiO2 alone and in the presence of UV was evaluated under different retention times (0–90 min) and concentrations of TiO2 nanoparticles (0.1, 0.2, 0.4, 0.8, 1 and 2 mg/ml). Efficiency of the reactor increased with increase in the retention time in the presence of UV. Simultaneous treatment of the contaminated water with both UV and TiO2 nanoparticles had a similar outcome. However, only a slight reduction in the concentration of microbes was noted in the presence of TiO2 in high concentrations. Considering the significant antimicrobial effects of nanoparticles, it is suggested to conduct similar studies on the effect of these compounds using animal models. By obtaining further information on other antimicrobial properties of such compounds, they could be utilized for removal of microbial surface contamination, especially in clinical settings.

This survey was performed using the following keywords ‘Vibrio cholerae’ and ‘Iran’ in the international databases including ISI Web of Science, PubMed, Scopus, and Google Scholar from January 1979 to December 2019. The statistical analysis was performed using SPSS software version 18.0 (IBM, New York, USA). In addition, P less than 0.05 was regarded as statistically significant. According to our results, the highest rate of incidence of cholera occurs in Sistan and Baluchestan (925/1636 cases), and after that Alborz (595/1636 cases) and Tehran (587/1636 cases) have shown high distribution. Among all provinces, Alborz province has demonstrated higher percentage of drug resistance than other ones (ampicillin 58.1%, co-trimoxazole 87%, erythromycin 87.5%, and furazolidone 74%). Moreover, lower antibiotic resistance has been shown in Golestan and Kermanshah, respectively. In spite of the fact that Iran has some big challenges in managing and controlling cholera incidence and antibiotic resistance, we believe that Iran has good perspective in future, as follows: special attention of the Iran government to cholera's free treatment, diagnosis and monitoring and eradication of it with coordination of WHO; Improving the level of food safety and quality; and finally, a ‘national action plan of Islamic Republic of Iran to combating antimicrobial resistance’ that were published to stop and reverse the trend of drug resistance in Iran.","PeriodicalId":49625,"journal":{"name":"Reviews in Medical Microbiology","volume":"42 1","pages":"183 - 190"},"PeriodicalIF":0.0,"publicationDate":"2020-03-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85879658","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}

S. agalactiae run into multiple niches through an infection, suggesting that regulatory mechanisms control the expression of specific virulence factors in this bacterium. Like other Gram-positive bacteria, Group B streptococcus (GBS) can create three-dimensional structures, such as biofilms that can increase their ability to colonize and maintain in the host. Biofilm formation has been investigated by GBS under laboratory conditions and is clearly controlled under environmental conditions. Significantly, antibodies that act against the proteins of the pili can prevent the creation of biofilms. The consequences of biofilm formation in the field of asymptomatic colonization and its dissemination remain invasive and its details are examined. The complex pathway leading to biofilm development in different species of microorganisms involves the contribution of both environmental conditions and genetic factors. Numerous genes or factors have been identified as being essential or required for biofilm formation. Such genes include those that regulate surface-exposed proteins, appendages, such as pili or fimbriae, and extracellular polymeric substance (EPS) matrix materials. Pilus seems to play a key role in adhesion and attachment to host cells both in Gram-negative and Gram-positive pathogens. Their involvement in the transition from planktonic growth to a surface-attached multicellular community has also been demonstrated in many studies. Three different types of pili have been characterized in GBS as potential virulence factors. For example, type 2a pili are involved in biofilm formation. Copyright 2019 Wolters Kluwer Health, Inc.

This study aimed to analyze the in-vitro activity of eravacycline against Gram-negative bacteria in published literature, to contribute to the international data on the antimicrobial stewardship programs. A systematic literature review was performed through the electronic databases from January of 2000 to December 2017 to cover all published articles relevant to our scope. Finally, nine studies met our inclusion criteria that were subjected to data extraction and review. The highest activity of eravacycline was against Escherichia coli isolates since in all reports eravacycline at a concentration of 0.5 mg/ml or less inhibited 90% of isolates. In contrast, the lowest activity was seen against Proteeae isolates since except for one report eravacycline at a concentration of at least 2 mg/ml inhibited 90% of isolates. The antibacterial activity of eravacycline against 13 collections of carbapenem-resistant bacteria consists of 1057 isolates was showed that eravacycline at a concentration of 2 mg/ml or less inhibited 90% of isolates. The only exception was for carbapenemresistant Proteeae which 90% of isolates were inhibited at a concentration of at least 4 mg/ml. In summary, eravacycline has a promising in-vitro antibacterial property against several nosocomial pathogens. This was an encouraging result that provides an option for treatment of infections caused by Gram-negative bacteria, regardless of resistance phenotype. However, further clinical studies are necessitate to provide clinical evidence to support these observations. Copyright 2019 Wolters Kluwer Health, Inc.
