Tel: +81-43-266-6723, Fax: +81-43-265-5544, E-mail: [email protected] Tuberculosis is one of the major bacterial diseases in Japan (1). Advances in the molecular epidemiological analysis of this disease have greatly improved t...

The study determined the genetic heterogeneity of Helicobacter pylori isolates from antrum and corpus of the same dyspeptic patients in a Thai population and determined the relationship between the antimicrobial susceptibility (AS) profile (antibiogram) and PCR-restriction fragment length polymorphism (PCR-RFLP) pattern. One hundred and nineteen H. pylori isolates comprising 7 single and 56 pai...

IS6110 fingerprinting of Mycobacterium tuberculosis is the standard identification method in studies on transmission of tuberculosis. However, intensive epidemiological investigation may fail to confirm transmission links between patients clustered by IS6110-restriction fragment length polymorphism (RFLP) typing. We applied typing based on variable numbers of tandem repeats (VNTRs) of mycobacte...

During 2009-2010, 161 tissue samples (142 placentas, 16 brains, and 3 livers) from aborted ovine fetuses on Sardinia Island, Italy, were tested for toxoplasmosis. Organs that showed a positive result by nested polymerase chain reaction (PCR) targeting the ITS1 region for Toxoplasma gondii were also amplified with 11 genetic markers (SAG1, 5'-SAG2, 3'-SAG2, SAG3, BTUB, GRA6, c22-8, c29-2, L358, ...

Isolates of Campylobacter jejuni shipped internationally often arrive in a noncultivable state. We describe a PCR-based methodology whereby phylogenetic information can be recovered from noncultivable C. jejuni stored in Wang's transport medium. The robustness of this methodology was initially tested using 5 previously characterized strains of C. jejuni isolated from various sources associated ...

capsules from a range of pathogenic bacteria are the key determinants of virulency. the capsule hasbeen implicated in virulence of pasteurella multocida. in this study a type-specific polymerase chain reaction(pcr) assay was used for capsular typing of 39 avian p. multocida isolates from iran. the pcr amplified afragment of 1044 bp from all of tested isolates. it was found that all avian p. mul...

Several studies have focused on polymorphisms of major histocompatibility complex (MHC) in sheep, Ovar-MHC. This molecule plays a pivotal role in antigen presentation for eliciting immune responses against invading pathogens. The best-characterized genetic control of disease resistance and immune response in animals is associated with MHC. Numerous molecular genetic investigations have been und...

background cervical cancer is the leading cause of death from cancer in under-developed countries. human papilloma virus (hpv) 16 and 18 are the most prevalent types associated with carcinogenesis in the cervix. conventional polymerase chain reaction (pcr), type-specific and consensus primer-based pcr followed by sequencing, restriction fragment length polymorphism (rflp) or hybridization by sp...

Thermotolerant Campylobacter spp. are a major cause of foodborne gastrointestinal infections worldwide. The linkage of human campylobacteriosis and poultry has been widely described. In this study we aimed to investigate the prevalence, antimicrobial resistance and genetic diversity of C. coli and C. jejuni in broilers from Ecuador. Caecal content from 379 randomly selected broiler batches orig...

Tuberculosis, caused by the bacterium Mycobacterium tuberculosis, remains one of the most serious global health problems. Molecular typing of M. tuberculosis has been used for various epidemiologic purposes as well as for clinical management. Currently, many techniques are available to type M. tuberculosis. Choosing the most appropriate technique in accordance with the existing laboratory condi...
