Abstract Background and Objective: Highly Active Antiretroviral Therapy (HAART) can effectively prevent the progression of HIV-1 replication and increase life expectancy. There are numerous causes of treatment failure and the leading one is drug resistance. Thus, we aimed to determine the HIV RT gene drug resistance mutations in patients treated with antiretroviral medications. Material...
Aim and Background: Candida Albicans is the most important cause of vulvovaginal candidiasis and resistance to azoles can occur via various mechanisms including, change in the ERG11 gene. This study aim was to identification of ERG11 gene mutations in drug resistant Candida albicans isolated from patients with Candida vaginitis and its association with infertility in Iranian women. Mat...
OBJECTIVES To test whether smeDEF overexpression leads to a predictable multi-drug resistance phenotype in Stenotrophomonas maltophilia and to measure the frequency with which smeDEF overexpression occurs in clinical isolates and in spontaneous drug-resistant mutants. METHODS Overexpression of smeDEF was induced in clinical isolates by the introduction of chromosomal mutations in smeT using a...
background methicillin-resistant staphylococcus aureus (mrsa) is considered a major cause of nosocomial and community infections. its prevalence varies from country to country, even between hospitals of a country. these bacteria often have multi-resistance and can be difficult to treat. objectives the current study evaluated the effect of hydroalcoholic extract of the stem bark of juglans regia...
abstract aims: the increasing usage of antibiotics can cause resistance to the treatment of infections, which can caused by bacteria, e.g. pseudomonas aeruginosa. the aim of this study was to trace the class i, ii and iii integrons in isolates of p. aeruginosa of nosocomial infection and determining the antibiotic resistance pattern of the bacteria. instrument & methods: in this cross-sectional...
tuberculosis is one of the most important infectious diseases and a major cause of morbidity and mortality in developing countries. multi drug resistant tuberculosis is a new threat, which can result in a high case fatality rate. this study was conducted to define the incidence of multidrug resistant tuberculosis in kermanshah. antibiogram was performed on pcr-confirmed isolates of mycobacte...
conclusions the study revealed a high prevalence of multi-drug resistance (mdr), class 1 integron, sccmec type iii, and spa type t030 amongst mrsa associated with burn wounds in an iranian hospital. the existence of sccmec type iii in burn patients emphasizes the nosocomial origin of these strains. objectives the aim of this study was to determine the distribution and molecular types of mrsa in...
بیماری میوه سبز مرکبات توسط باکتری سخت کشت candidatus liberobacter asiaticus ایجاد می شود که اولین بار در چین توصیف شده است و در سال 1919 با نام رسمی huanglongbing معرفی گردید. این بیماری یکی از پرخسارت ترین بیماری های مرکبات درجنوب شرقی آسیا، شبه قاره هند، آفریقای جنوبی و شبه جزیره عربستان است. این بیماری در سال 1386 از جنوب ایران گزارش گردید. برای درک مکانیسم مولکولی برهمکنش میزبان-پاتوژن از ...
background and aims: lamivudine is amongst the antiviral for drug chronic hepatitis b treatment. during therapy with lamivudine, variants may emerge with ymdd mutation in the reverse transcriptase (rt) region of polymerase gene. this mutation might have a role in drug resistant for hbv. materials and methods: hbv dna extraction from serum sample of 88 patients, were subjected to nested pcr for ...
