Terminal restriction fragment length polymorphism (T-RFLP) analysis has the potential to be useful for comparisons of complex bacterial communities, especially to detect changes in community structure in response to different variables. To do this successfully, systematic variations have to be detected above method-associated noise, by standardizing data sets and assigning confidence estimates ...

Seventy families with Duchenne muscular dystrophy (DMD) known to the Institute of Child Health fall into three categories with respect to potential linkage analysis with the X chromosome DNA markers RC8 and L1.28 that bridge the DMD gene. Families in which there is at least one obligatory female heterozygote (n = 13). Here 'prediction' and 'exclusion' of DMD gene transmission may be possible, t...

A total of 20 skin lesion samples collected from patients with cutaneous leishmaniasis (CL) attended AL-Karamah Teaching Hospital at Wasit province. Dermal scrapings were analysed by examination of Giemsa-stained smears, by Conventional PCR and RFLP-PCR methods. The incidence rate with CL was 80% by using Giemsa-stained and 100% for both PCR and RFLP-PCR. Twelve (60%) of isolates were typed as ...

New primer-enzyme combinations for terminal restriction fragment length polymorphism (T-RFLP) targeting of the 16S rRNA gene were constructed by using the T-RFLP analysis program (designated TAP T-RFLP) located at the Ribosomal Database Project website, and their performance was examined empirically. By using the fluorescently labeled 516f primer (Escherichia coli positions 516 to 532) and 1510...

Urine samples from 19 nursing home patients with long-term urinary catheters were cultured every 3 months for 18 months. Providencia stuartii, present in 74% of the elderly and in 59% of urine specimens, was the most frequently isolated bacteria. The persistence of P. stuartii was significantly higher among females than among males. In order to study the epidemiology of bacteriuria in this nurs...

BACKGROUND The present study was carried out to investigate the accurate status of ovine Theileria infection in sheep from Ahvaz and surrounding region, a tropical area southwest Iran. METHODS A PCR-RFLP method based on 18S ribosomal RNA gene was designed which could detect and differentiate Theileria and Babesia spp. and also differentiate main Theileria species in sheep at the same time. 11...

The M-protein genes (emm genes) of 103 separate impetiginous Streptococcus pyogenes isolates were sequenced and the sequence types were compared to the types obtained by Vir typing. Vir typing is based on restriction fragment length polymorphism (RFLP) analysis of a 4- to 7-kb pathogenicity island encoding emm and other virulence genes. By using both HaeIII and HinfI to generate RFLP profiles, ...

Aim: Identification of wild pig and domestic pig is essential to prevent illegal poaching of wild pig and to implement Wildlife (Protection) Act, 1972. PCR-RFLP was used to differentiate Wild pig (Sus scrofa cristatus) from Domestic pig (Sus scrofa domestica) meat. Materials and Methods: DNA was isolated from meat samples of both the sub species and a fragment of Cytochrome b gene was amplified...

The study aims to investigate fungal community structures and dynamic changes in forest soil lignocellulose-degrading process. rRNA gene clone libraries for the samples collected in different stages of lignocellulose degradation process were constructed and analyzed. A total of 26 representative RFLP types were obtained from original soil clone library, including Mucoromycotina (29.5%), unclass...

BACKGROUND It is clinically important to detect and type human papillomavirus (HPV) in a sensitive and specific manner. OBJECTIVES Development of a nested-polymerase chain reaction-restriction fragment length polymorphism (nested-PCR-RFLP) assay to detect and type HPV based on the analysis of L1 gene. METHODS Analysis of published DNA sequence of mucosal HPV types to select sequences of new...
