Cellular localization of oestrogen receptor alpha (ERalpha) and beta (ERbeta) proteins were studied in human testis samples using immunohistochemistry, and the expression of the corresponding mRNA was examined with reverse transcription-polymerase chain reaction (RT-PCR). Seven men, aged 28-48 years, who underwent diagnostic testicular biopsy because of azoospermia or to give spermatozoa for in...

background : haemonchosis has a negative effect on the farming industry throughout the world, especially in the tropic and sub-tropic countries. the present study was carried out to differentiate haemonchus species from its main hosts in iran, including sheep, goat and camel.   methods: the identification took place based on the morphometrics of the spic-ules and molecular characters. two hundr...

Backgrounds: Neospora caninum is an Apicomplexan parasite. It causes paralysis and neuromuscular disorders in dogs and abortion in cattle. Although contamination with N. caninum is common in stray dogs, most of the dogs are infected with subclinical neosporosis. Objectives: The objective of this study was to evaluate the presence of N. caninum in multiple tissues and cerebrospinal fluid (CSF) u...

Although the hindgut of some insects represents a rich source of intestinal trichomonads, their diversity is only poorly understood. The aim of the present study was to investigate the presence and abundance of intestinal trichomonads in true bugs (Heteroptera). We microscopically examined intestinal contents of more than 780 specimens belonging to 28 families of true bugs from localities in Ch...

Conventional culture methods were compared to a multiplex polymerase chain reaction (PCR) assay for simultaneous detection of Salmonella spp., Listeria monocytogenes, and Escherichia coli O157:H7 from enrichment cultures of various types of artificially inoculated and naturally contaminated foods. The multiplex PCR assay was evaluated in 44 types of spiked food samples, including meat, produce,...

campylobacter jejuni is a major cause of food-borne diarrhea in many countries. poultry and poultry products are known as important sources of human campylobacteriosis. in this study, conventional culture and multiplex pcr methods were compared for the detection of c. jejuni isolated from poultry carcasses. a total of 100 samples, representing 20 broiler flocks, were collected from poultry carc...

Anaplasma bovis is a leukocytotropic agent of bovine anaplasmosis and there is no available information about molecular study on this agent in cattle of Iran. In this study a total 150 cattle blood samples were collected from central part of Iran. The presence of A. bovis examined using light microscopic detection and species-specific nested polymerase chain reaction (nested-PCR) based on 16S r...

We examined 26 atherosclerotic lesions and 14 nondiseased aorta specimens to detect the periodontopathogenic part of the bacterial 16S rRNA locus by PCR. Treponema denticola sequence of the 16S rRNA locus was found in 6 out of 26 DNA samples (23.1%) from the formalin-fixed, paraffin-embeded atherosclerotic lesions obtained during surgery but not in any of the 14 nondiseased aorta samples from d...

Methods We collected data for all 398 confirmed or probable cases of CDI admitted during 15 November 2013-28 February 2014 in 11 hospitals: 5 from Bucharest, and 7 from Cluj, Iaşi, Timişoara, Târgu Mureş and Braşov. PCR ribotyping was performed at Cantacuzino Institute and E-test (for moxifloxacin and metronidazole) and binary toxin gene identification (PCR) were performed at Matei Balş Institu...

Application of the polymerase chain reaction (PCR) to disease diagnosis is limited in part by the presence of PCR inhibitors. Inhibition can be overcome and sensitivity increased by culturing bacteria on agar media prior to PCR (termed BIO-PCR). However, Xylella fastidiosa grows slowly, requiring 10–14 days for visible colonies to appear. In this study an agarabsorption BIO-PCR method for detec...
