Two groups of Trypanosoma congolense isolates collected from cattle in 1996 (n=39) and 2003 (n=38) in the Eastern Province of Zambia were analyzed by BclI-PCR-RFLP to assess the evolution of diminazene aceturate (DA) resistance over a period of seven years. The results show a significant increase of DA resistance in this relatively short period of time. In 1996, among the 39 isolates, 61.5% wer...

Increased frequency of methicillin-resistant Staphylococcus aureus (MRSA) in hospitalized patients requires rapid and reliable characterization of isolates for control of MRSA spread in hospitals. This study evaluated polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) as a molecular typing technique for MRSA strains on the basis of protein A (spa) and coagulase (coa) ...

BACKGROUND/AIMS The development of effective, accurate, and rapid diagnostic methods for Mycobacterium infection and mycobacterial species identification is required. Polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) is an easy, rapid and inexpensive technique for identifying Mycobacterium spp. METHODS We performed PCR-RFLP to detect and identify Mycobacterium spp....

Fast and inexpensive identification of epidemiological links between limited number of Mycobacterium tuberculosis strains is required to initially evaluate hospital outbreaks, laboratory crosscontaminations, and family or small community transmissions. The ligation-mediated PCR methods (LM-PCR) appear sufficiently discriminative and reproducible to be considered as a good candidate for such ini...

We present here the first comparative analysis at the population level between Restriction Fragment Length Polymorphism (RFLP) and control region sequence polymorphism in a large and homogeneous Senegalese Mandenka sample. Eleven RFLP haplotypes and 60 different sequences are found in 119 individuals, revealing that a very high level of mtDNA diversity can be maintained in a small population. A...

OBJECTIVES The aim of the present study was to develop a simple, quick and cheap method to process whole-blood samples for the molecular techniques polymerase chain reaction (PCR) and restriction fragment length polymorphism (RFLP) without the use of expensive reagents or sophisticated machines. MATERIALS AND METHODS Venous whole-blood samples were collected from 40 individuals. The samples w...

OBJECTIVES Rapid and accurate detection of Brucella abortus and Brucella melitensis from clinical samples is so important because antibiotic treatment has major side effects. This study reveals a new method in detection of clinical samples of brucellosis using real-time PCR and high-resolution melt (HRM) curve analysis. MATERIALS AND METHODS 160 brucellosis suspicious samples with more than 1...

BACKGROUND & OBJECTIVES The difficulties in diagnosis of neonatal sepsis are due to varied clinical presentation, low sensitivity of blood culture which is considered the gold standard and empirical antibiotic usage affecting the outcome of results. Though polymerase chain reaction (PCR) based detection of bacterial 16S rRNA gene has been reported earlier, this does not provide identification o...

BACKGROUND/AIM To develop a novel polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) protocol using a new genomic marker sequence and a novel set of restriction enzymes in order to detect and discriminate 2 Echinococcus species, E. granulosus and E. multilocularis, found in formalin-fixed paraffin-embedded (FFPE) human tissues. MATERIALS AND METHODS DNA was isolated...

Endophytic persistence of inoculated plant growth promoting bacteria (PGPB) involves interaction with the host and host’s indigenous endophytic bacterial communities. This study investigated Methylobacterium oryzae CBMB20 into rice endosphere together impact inoculation on diversity community structure root shoot endophytes in Oryza sativa L. spp. indica cv. IR29. Terminal Restriction Fragment ...
