Streptococcus agalactiae , S. dysgalactiae and S. uberis are Gram-positive bacterial pathogens that affect cows in dairy herds. These are considered as the major causes of economic losses of dairy producers without a control program. To reveal the role of these agents in inducing subclinical mastitis in dairy cattle in Ahvaz, 100 CMT-positive milk samples and 20 CMT-negative milk samples were c...
Abstract Background and Objective: Nowadays, nosocomial infection is one of the greatest problems in hospitals. Normal flora of staff’s hands and the bacterial agents on the surface of medical equipment can become progressively colonized with potential pathogens during patient care. This study was carried out to determine the bacterial agents existed on staff’s hands and in the wards of ho...
Background and Objectives: Traditionally, diagnosis of the agents of infectious diseases is based on conventional or phenotypic methods. Due to the lack of growth of some infectious agents, these methods are very difficult or impossible for diagnosis of some bacteria. The advent of molecular techniques has more or less influences on the detection of microbial infections. This article addresses ...
Background and Objective: Lactobacilli are known for their probiotic activities and potential to combat pathogens. This study aimed to investigate the antimicrobial activity of Lactobacillus strains isolated from various sources against pathogenic bacteria, with the objective of identifying potential bacteriocin producers. Methods: A total of 140 samples were collected from different sources. ...
Seven species of bacterial select agents were tested for susceptibility to monochloramine. Under test conditions, the monochloramine routinely maintained in potable water would reduce six of the species by 2 orders of magnitude within 4.2 h. Bacillus anthracis spores would require up to 3.5 days for the same inactivation with monochloramine.
BACKGROUND:The bacterial contamination of fertile eggs isthe most common cause of embryonic death in ostrich hatcheryunits leading to financial loss in ostrich industry. OBJECTIVES:The aim of this research was to investigate the bacterialcontamination status, with emphasis on Escherichia coli, ofostrich hatcheries and the antimicrobial resistance profile ofisolated Escherichia coli. METHODS:Ato...
Antibiotics can cure diseases caused by bacterial infections, but their widespread use have some side effects, such as probiotic reduction. There is an urgent need for agents that...
