conclusions methicillin-resistant staphylococcus aureus is an increasingly common cause of nosocomial infections. our results are in agreement with those of other studies reporting that a few specialized clones are responsible for most cases of mrsa nasal carriage. in this study, mrsa strains isolated from different wards of hospital were closely related when analyzed by coagulase gene typing. ...

conclusions using the pcr-rflp method, three distinctive h. pylori caga genotypes were detected in antral biopsies. genotype i, which was predominant among the isolates, was significantly associated with gastritis. however, the data showed that caga genotype iii may play a role in duodenitis and duodenal ulcers in patients infected with h. pylori. patients and methods a total of 161 gastric bio...

Comparison of the frequency of occurrence of restriction fragment length polymorphisms in control human DNAs and DNAs from infants dying from sudden infant death syndrome has indicated no significant difference in the case of restriction fragment length polymorphisms associated with the heat shock protein genes hsp70 and hsp90. A highly significant difference was detected, however, in the case ...

Growth hormone gene plays a critical role in regulating growth and metabolism which leads to potential correlations between the polymorphisms of this gene and economic trait. A 776 bp fragment within the intron 1 region of the growth hormone gene from 346 individuals of an F2 population of Japanese quail was amplified. The polymerase chain reaction (PCR) product was digested using MspI restrict...

We describe a new basis for the construction of a genetic linkage map of the human genome. The basic principle of the mapping scheme is to develop, by recombinant DNA techniques, random single-copy DNA probes capable of detecting DNA sequence polymorphisms, when hybridized to restriction digests of an individual's DNA. Each of these probes will define a locus. Loci can be expanded or contracted...

conclusions the results revealed that the strains under study could be epidemically related. it seems that an alternative subtyping method is needed to study the relationship among clinical s. sonnei strains and their transmission. here, we reported for the first time, two strains of s. sonnei with a different pcr-rflp pattern for ipah gene. results all shigella isolates were positive for both ...

Objective-To characterise Neisseria gonorrhoeae isolates by restriction fragment length polymorphisms (RFLPs) in ribosomal RNA genes. Design-Generation of RFLP patterns by HincII restriction of rRNA genes followed by hybridisation with a nonradioactive labelled broad spectrum 16 + 23S rRNA gene probe. This typing method was developed and compared with MAb based serotyping. Specimens-Forty three...
