In this study 130 bulk tank milk samples which were delivered to the Pegah Pasturisation Factory inMashhad were collected randomly during the summer months. Samples were firstly enriched in modifiedtrypticase soy broth containing novobiocin, followed by plating onto sorbitol MacConkey agar supplementedwith cefixime and potassium tellurite for isolation of Escherichia coli O157:H7. Consequently ...
Today, it is nearly 25 years past from investigation of Shiga toxigenic Escherichia coli (STEC) which is able to produce Shiga toxins and cause different gastroenteritis. Since incidence of gastroenteritis due to STEC is increasing, it's necessary to develop rapid, specific and accurate procedures like PCR. In this study, we used PCR method to detect and identify STEC in cultures of 55 Escher...
Troxerutin, a derivative of the natural bioflavonoid rutin, has important biological effects, including immunostimulatory activity. This study aimed to evaluate the effects of dietary troxerutin supplement on histology and mRNA expression of the genes encoding lysozyme and tumor necrosis factor-α in goldfish, Carassius auratus skin. Fish fingerlings with mean initial weights of 2.74 ± 0.08 g we...
Background: The aim of this study was compared the efficacy of the designed primers and already published primers for detection of the exoA, oprL and algD genes by PCR assay for finding a rapid, accurate and highly sensitive and specific procedure to detect the Pseudomonas aeruginosa in the serious and fatal infections such as cystic fibrosis disease, burned individual.Methods: A total of 150...

Background and Aim: Pseudomonas aeruginosa is one of the most important factors in hospital infections, especially in patients with immune deficiency and Childhood diseases. The Virulence of bacteria are due to the presence of the Pyoverdine gene, which has many effects on the wild type of bacteria during the pathogenic pathway. Identification of different classes of PVD gene is necessary for t...
streptococcus agalactiae is acommensalorganism, but it may cause infection in susceptible hosts. the aim of this study was to evaluate pcr assay compared with conventional culture method for direct detection of streptococcus agalactiae . total of 203 paired low vaginal swabs were collected from women at 35-37 weeks of pregnancy from june 2013 through february 2014 for detection of streptococcus...
The present study was aimed to identify the frequency of coagulase (Coa) and thermonuclease (Nuc) genes and Staphylococcal enterotoxin A (Sea) production among Staphylococcus aureus isolated from various sources in Shiraz. Moreover, the correlation between the Sea gene and coagulase and thermonuclease enzymes is also considered. A total of 100 S. aureus were isolated from various sources includ...
