BACKGROUND In comparison to restriction fragment length polymorphism (RFLP) typing, variable number of tandem repeat (VNTR) typing is easier to perform, faster and yields results in a simple, numerical format. Therefore, this technique has gained recognition as the new international gold standard in typing of Mycobacterium tuberculosis. However, some reports indicated that VNTR typing may be le...

Purpose The objectives of the present study were to characterize the clinical isolates prevailing in the northeast of Jiangsu and to investigate the mode of transmission. The study also aimed to explore the extent to which Mycobacterium tuberculosis strains contributed to drug resistance and the possible factors related to the recent transmission. Patients and methods We consecutively enrolle...

Background. Considering that Hormozgan province in Iran (southern part of Iran on the Persian Gulf) is among the areas with high prevalence of MDR-MTB and attracts so many sailors and tourists, genetic diversity of MTB isolates circulating in this part of Iran was evaluated. Pattern of TB transmission was also examined. Methods and Material. A total of 38 isolates of MTB were cultured from TB p...

In this study we report on the development of a multilocus variable-number tandem-repeat (VNTR) analysis (MLVA) method for the molecular typing of Mycoplasma pneumoniae. The genomic content of M. pneumoniae M129 was analyzed for VNTRs, and 5 of the 17 VNTRs identified were selected for use in an MLVA assay. The method was based on a GeneScan analysis of VNTR loci labeled with fluorescent dyes b...

Background Brucella canis is a pathogenic bacterium that causes brucellosis in dogs, and its zoonotic potential has been increasing in recent years. B. canis is a rare source of human brucellosis in China, where Brucella melitensis has been the major pathogen associated with human brucellosis outbreaks. In late 2011, a case of a B. canis infection was detected in a human patient in Zhejiang Pro...

BACKGROUND We aimed to characterize the genetic diversity of drug-resistant Mycobacterium tuberculosis (MTb) clinical isolates and investigate the molecular epidemiology of multidrug-resistant (MDR) tuberculosis from Minas Gerais State, Brazil. METHODS One hundred and four MTb clinical isolates were assessed by IS6110-RFLP, 24-locus mycobacterial interspersed repetitive units variable-number ...

چکیده زمینه و هدف: امروزه پیدایش سویه‌های MDR به عنوان یک مشکل جدی در برابر برنامه کنترل بیماری سل در اغلب کشورها و در سطح جهانی مطرح است. از سال 1990 تاکنون موارد متعددی از گسترش سل MDR در مناطق مختلف جهان گزارش شده است، که عمدتاً به دلیل استفاده نابجا و نادرست از داروهای سل است. از علل اصلی بروز مقاومت داروئی به عنوان یک عارضه ساخت دست بشر می‌توان به اشتباه در طبقه‌بندی، عدم پایش حین درمان بی...

BACKGROUND The Philippines is designated as one of the high tuberculosis (TB) burden countries by WHO. We conducted a molecular epidemiologic analysis of Mycobacterium tuberculosis isolates collected from patients consulting at the health clinics in the city of Santa Rosa, Laguna, a suburban community in the Philippines. METHODS A total of 116 M. tuberculosis isolates were characterized and g...

The Vologda Region is characterized by a relatively calm epidemic situation for tuberculosis in Russia: the incidence rate 2010—2018 decreased from 45.2 to 15.8 per 100 thousand of population (44.4 Russia). However, proportion patients with multiple drug resistance (MDR) pathogen increased 12.1% 2016 23.7% 2018. aim study was characterize genetic structure M. and identify main genotypes associa...

The intra-herd and intra-host genetic variability of 123 Cryptosporidium parvum isolates was investigated using a multilocus fragment typing approach with eleven variable-number tandem-repeat (VNTR) loci and the GP60 gene. Isolates were collected from intensively farmed diarrheic pre-weaned calves originating from 31 dairy farms in three adjoining regions in northern Spain (País Vasco, Cantabri...
