background and objectives: patients at intensive-care-unit (icu) are at risk of acquiring nosocomial infections which contributes to higher rates. approximately 25% of all hospital infections and 90% of outbreaks occur in icus. multi-resistant gram-negative rods are important pathogens in icus, causing high rate of mortality. the purpose of this study was to investigate the antimicrobial resist...

The evolution of the plant immune response has resulted in a highly effective defense system that is able to resist potential attack by microbial pathogens. The primary immune response is referred to as pathogen associated molecular pattern (PAMP) triggered immunity and has evolved to recognize common features of microbial pathogens. In response to the delivery of pathogen effector proteins, pl...

Background : Since recogntion of probable reservoirs of nosocomial infections is important for determining the kinds and antibiogram pattern of hospital pathogens in Shohadaye-Ashayer hospital environment, this descriptive cross- sectional study was done. Materials and methods: Totally, 1020 gowns were sampled in an interval of one month and three times of sampling. Samples were carried to lab...

wild cage birds can be carriers of some human pathogens and some of these can be transmitted to people. campylobacter bacteria are the most common bacteria that cause gastroenteritis worldwide. considering people's interests to keep wild cage birds and the potential ability of wild cage birds to transmit campylobacter to humans, the present study was conducted to evaluate campylobacter inf...

The gut mucosa acts as a barrier against microbial invaders, whereas resident commensal and foreign invading bacteria interact intimately with the gut epithelium and influence the host cellular and immune systems. The epithelial barrier serves as an infectious foothold for many bacterial pathogens and as an entry port for pathogens to disseminate into deeper tissues. Enteric bacterial pathogens...

While the interactions between Gram-positive bacteria and platelets have been well characterized, there is a paucity of data on the interaction between other pathogens and platelets. However, thrombocytopenia is a common feature with many infections especially viral hemorrhagic fever. The little available data on these interactions indicate a similarity with bacteria-platelet interactions with ...

Background: Consumption of raw cheese may be associated with different diseases. This study aimed to evaluate behavior of four pathogenic bacteria during manufacture and ripening of Protected Designation of Origin (PDO) Pecorino Siciliano cheese. Methods: The experimental cheese groups were inoculated with pathogenic bacteria, including Escherichia coli O157, Listeria monocytogenes, Salmonella...
