A total of 129 clinical isolates of Mycobacterium tuberculosis representing 91 patients were typed by a combination of direct-repeat (DR)-based spoligotyping and an inter-IS6110-PGRS (polymorphic GC-rich region)-PCR, also designated double-repetitive-element PCR (DRE-PCR). During the first phase of this investigation, 72 clinical strains representing 52 patients were initially typed by IS6110-r...

Moraxella (Branhamella) catarrhalis, a causative agent of otitis media, sinusitis, and exacerbation of bronchitis, has acquired widespread ability to produce beta-lactamase and can be nosocomially transmitted. The typing methods used in epidemiological analyses of M. catarrhalis are not optimal for genetic analyses. Two methods, a multiple-locus Southern blot (SB) method and a single-locus PCR-...

Background: Candida albicans is the predominant yeast reported from human infection. Non-albicans species have been recently developed as medically vital fungi. Therefore, it essential to detect and identify pathogens at level prescribe appropriate treatment. Methods: This study assessed two complementary methods, including real-time polymerase chain reaction-high resolution melt (PCR-HRM) reac...

Objective: The objective of this study was to investigate the group/subgroup phytoplasma agent in peppers showing symptoms. Material and Methods: In study, plants collected from Iğdır province 2020 were analyzed using direct nested PCR tests, BLASTn, iphyClassifier, Mega 7, pDRAW32 programs used. Results: tests performed, approximately 1.2 kb DNA fragments specific obtained. 16S rRNA nucleotide...

In order to detect several new HLA-A class I alleles that have been described since 1998, the original PCR-RFLP method developed to identify the 78 alleles recognized at that time at high resolution level was adapted by us for low and medium resolution levels using a nested PCR-RFLP approach. The results obtained from blood samples of 23 subjects using both the PCR-RFLP method and a commercial ...

A study was conducted to develop a Trypanosoma vivax (T. vivax) specific PCR based on the T. vivax proline racemase (TvPRAC) gene. Forward and reverse primers were designed that bind at 764-783 bp and 983-1002 bp of the gene. To assess its specificity, TvPRAC PCR was conducted on DNA extracted from different haemotropic pathogens: T. vivax from Nigeria, Ethiopia and Venezuela, T. congolense Sav...

Aim: Chital and sambar are the common wild small herbivores, which are vulnerable to poaching for their meat. Many times poachers claim the wild meat to be that of goat or sheep. Hence, authentic evidences are required to stop such wildlife crime. The present investigation was carried out to study the species specific PCR-RFLP patterns for meat identification of chital and sambar and then diffe...

A PCR-restriction fragment length polymorphism (RFLP) method was developed in order to screen a large number of strains for impaired adhesion to epithelial cells due to expression of truncated InlA. inlA polymorphism was analyzed by PCR-RFLP in order to correlate inlA PCR-RFLP profiles and production of truncated InlA. Thirty-seven Listeria monocytogenes strains isolated from various sources, i...

Abstract. The purpose of the research Was to study genetic diversity bovine leukemia virus isolates obtained in Belgorod Region using restriction fragment length polymorphism method (RFLP). Scientific novelty. Bovine leukosis is one most common chronic infectious diseases cattle many countries world, which causes significant economic losses livestock industry. typing (BLV), its structure, evalu...

To shed light on the epidemiology of ascariasis in Ecuador and Zanzibar, 177 adult worms retrieved by chemo-expulsion from either people or pigs were collected, measured and subjected to polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) analysis of the ribosomal internal transcribed spacer (ITS) region. Upon double digestion with RsaI and HaeIII, PCR-RFLP analysis re...
