Staphylococcus aureus is a major pathogen in the transmission of diseases from animals to humans and vice-versa.Various infections, such as mastitis in cattle, sheep and goats, as well as gastroenteritis due to food poisoning in humans are the most frequent problems caused by S. aureus. The bacteria also lead to severe economic losses in dairy industry. A major virulence facto...

Infectious bronchitis (IB) virus genome codes for four structural proteins, among which the S1 subunit of spike glycoprotein comprises the major epitopes to induce neutralizing antibodies. This study involved the comparison of the full S1 sequences of five IB viruses, namely two Massachusetts and three 793/B serotypes, isolated from IB outbreaks during 2001-2002, with all other Iranian an...

P48 protein of Mycoplasma agalactiae is used to diagnose infection and was identified as potential vaccine candidate. According to the genetic nature of mycoplasma and variable sensitivity in P48-based serological diagnosis tests, intra species variation of P48 nucleotide sequence investigated in 13 field isolates of difference province of Iran along with three vaccine strains. Samples were col...

The present investigation aims to the isolation of Streptomycetes from saline soil. The isolates were varied in color to aerial vegetative mycelia, morphology of conidospore surface, melanin production, utilization of carbon; nitrogen source and fatty acid analysis, as well as physical and chemical characters for their habitat soil. Streptomycetes isolates exhibiting wide range of variability. ...

objective: fusarium diseases that cause grain mold and stalk rot of millet are the most important diseases, of these crops in iran. fusarium can cause stalk rots, ear rots, and grain mold, resulting in serious production losses in millet, and produce mycotoxins that are harmful to both humans and domesticated animals.  methods: a total of 23 fusarium isolates were recovered from foxtail millet ...

Background: There is a growing concern on the impact of the presence of extended-spectrum β-lactamase (ESBL) producing Escherichia coli isolated from animals on public health. OBJECTIVES: The aim of this study was to investigate the presence of three classes of ESBL genes in E. coli isolates from sheep and broilers at a slaughter in Urmia region, Iran. METHODS: A total of 111 E. coli isolates w...

Background and Aims: The rate of urinary tract infection caused by the extended-spectrum-β-lactamase- (ESBL) producing Escherichia coli (E. coli) is increasing worldwide. This study aimed to assess the frequency of blaCTX-M genes in the E. coli isolated from urinary tract infection (UTI) in outpatients. Methods: 240 E. coli bacteria were isolated from the outpatients’ urine samples in the Kerma...
