Objective(s): Listeria monocytogens, Bacillus cereus and Campylobacter jejuni are three toxin producing bacteria over the world, especially in Iran, and it is essential to find a certain, rapid procedure to identify these microorganisms. In this research, these bacteria were simultaneously detected by multiplex PCR technique in foods. Materials and Methods: The primary approval of bacterial str...

Free-living nano-sized flagellates are important bacterivores in aquatic habitats. However, some slightly larger forms can also be omnivorous, i.e., forage upon both bacterial and eukaryotic resources. This hitherto largely ignored feeding mode may have pronounced implications for the interpretation of experiments about protistan bacterivory. We followed the response of an uncultured group of o...

BACKGROUND: Staphylococcal foodborne intoxication is the most common cause of foodborne illnesses by Staphylococcus aureus strains and most are caused by the enterotoxins of S. aureus. Staphylococcal enterotoxin A (SEA) is the most frequently responsible for staphylococcal food poisoning outbreaks. From a food safety and human health point of view, lactic acid bacteria (LAB) may provide a promi...

A problem arises when a plant, animal, or person becomes infected with a disease-causing bacterium that harbors antibiotic resistance to the drug that would be the most suitable treatment for that infection. In many cases, other drugs, to which the bacteria is not resistant, can be used to combat the infection. However, in cases where our choices of effective drugs are limited, or the bacterium...

Lactic acid bacteria (LAB) are gram positive and non- spore forming bacteria that can produce some special substances for growth inhibition of pathogenic, non-pathogenic and food spoilage bacteria. The aim of this study was to determine the inhibitory effects of Lactobacillus acidophilus PTCC1643 (DSM 20079) and Lactobacillus plantarum PTCC 1058 (ATCC 8014) cultural supernatants against urinary...

Abstract In this study the wastewater treatment of a gas refinery was investigated by using an aerobic trickle bed filter bioreactor. Using a methanothrophic bacterium was the only difference of this experiment from the common aerobic wastewater treatment processes. In addition to reach the standards of wastewater treatments the other goal of using this special bacterium was the productio...

In addition, the effectiveness of a 2-g single dose of metronidazole was benefits of partner treatment were noted in the initial cure rate by Gramstained smear . In bacterial vaginosis (BV), the balance gets upset, and one type of bacteria in the vagina (called anaerobic bacteria) multiplies, whilst another type (called . Metronidazole 400mg For Trichomonas 2g Single Dose 5 Tablets is a one tim...

Bacteriophages are viruses that infect and lyse bacteria. Interest in the ability of phages to control bacterial populations has extended from medical applications into the fields of agriculture, aquaculture and the food industry. Here, the potential application of phage techniques in wastewater treatment systems to improve effluent and sludge emissions into the environment is discussed. Phage-...
