MOTIVATION Despite more than two decades of research, HIV resistance to drugs remains a serious obstacle in developing efficient AIDS treatments. Several computational methods have been developed to predict resistance level from the sequence of viral proteins such as reverse transcriptase (RT) or protease. These methods, while powerful and accurate, give very little insight into the molecular i...

background: enterococcus spp., belonging to the group of lactic acid bacteria, are gram-positive ubiquitous commensals of the intestines of human beings as well as warm-blooded animals. the main objective of this study was to determine the occurrence and antimicrobial resistance of enterococcus spp. isolated from lettuce and irrigation water in abidjan, côte d'ivoire. methods: a total of 7...

background : republic of azerbaijan is considered as an area with high prevalence of multi-drug resistant tuberculosis. uncontrolled travelling of azerbaijanis people to iran is the issue that needs to be considered as an important issue. methods : this study was conducted on 32 patients with tuberculosis from baku–nakhchivan and 48 patients from iran during 2012 to 2014. colonies of mycobacter...

conclusions: this study highlighted the need to establish antimicrobial resistance surveillance networks for p. aeruginosa to determine the appropriate empirical treatment regimens. the high prevalence of multidrug resistance and production of esbls in p. aeruginosa isolates confirms the necessity of protocols considering these issues in the hospitals. results: the resistance against broad-spect...

background: one of the fundamental issues of infectious disease treatment is drug resistance. the aim of the present study was to investigate the first-line anti-tuberculosis drug resistance rates and determine the risk factors related to multidrug resistant mycobacterium tuberculosis.methods: from march 2011 to september 2012, mycobacterial strains were collected from one hundred fifteen diagn...

background: this study was done to detect multidrug resistant (mdr) and extremely drug resistant (xdr) of pseudomonas aeruginosa among strains isolated from patients in tehran, iran, due to importance of these phenotypes in treatment of human infections. methods: eighty eightp. aeruginosa were isolated from patients in tehran, iran, and identified by routine methods and pcr for oprl gene. their...

results the k. pneumonia isolates were resistant to erythromycin (70%), cefixime (53.3%), tetracycline (50%) and ceftazidime (36.6%). the amplification of teta and tetb genes of k. pneumonia revealed that all of the isolates harbored these genes. conclusions resistance to tetracycline and other antibiotics, and the presence of various resistance genes in k. pneumonia strains are alarming signs ...

biofilm of pseudomonas aeruginosa, an opportunistic pathogen, can cause serious health problems, such as chronic infections, especially in immunocompromised patients. many studies have suggested administration of new generation of antibiotics, as p. aeruginosa biofilms have developed high resistance to antimicrobial drugs. this study reports the inhibitory effect of three medicinal plant extrac...

objective: to investigate microorganisms causing bacteremia in jordanian children and to assess their sensitivity to various groups of antimicrobials. methods: a retrospective study was conducted on positive blood cultures taken from 378 children aged below 15 year, who sought medical attention at princess rahmah hospital between january and december/2008. results: out of 4475 tested blood samp...
