Practically and ethically attractive as model systems, invertebrate organisms are increasingly recognized as relevant for the study of bacterial pathogenesis. We show here that the nematode Caenorhabditis elegans is susceptible to a surprisingly broad range of bacteria and may constitute a useful model for the study of both pathogens and symbionts.

Background and Objective: Food-borne diseases are among the most important public health problems. Among them, Salmonella is one of the most important food pathogens. Different Salmonella serotypes enter body through food and causes food infections in consumers. One of the most important evaluation criteria for health is to determine the microbial load of food. Materials and Methods: In this s...

Mushroom-forming fungi establish mutual beneficial interactions with plants and degrade organic waste. These also play an important role in human societies to produce mycelium materials, as a source of medicinal compounds, food. Bacteria interact mushroom-forming not only competitors for nutrients pathogens but interactions. This review discusses the positive bacteria during different stages li...

Objectives Periodontal diseases are one of the common oral diseases and microbial oral flora is one major factor responsible for it. Elimination of periodontal pathogens is particularly important in managing the periodontal state. This study aimed to assess the antibacterial effects of Nanosil, chlorhexidine (CHX) and probiotic mouthwashes on periodontal pathogens. Methods In this in-vitro stu...

Fish parasites act as a vector of other pathogenic diseases such bacteria and virus in fish. Although it has been long known that fish can for bacterial pathogens, their role the transmission specific pathogens via particular off-host stage neglected. The aim present study was to disclose if copepod parasite, Lernanthropus kroyeri stage, store up aquatic pathogens: Aeromonas hydrophila, Photoba...

Introduction: Presently, bacteremia is the principal cause of morbidity in patients undergoing hemodialysis. Gram-negative bacteria account for approximately 50 percent of documented infections. Endotoxins released during lysis of gram negative bacteremia result in inflammatory and defense response by the body and if not treated promptly result in septic shock and ultimately death of the patie...

Lactobacilli commonly used as a probiotic and they can be isolated from various sources such as fermented foods and gastrointestinal tracts of humans and animals. The aims of this study were isolation and identification of lactobacilli from honey and investigation of some probiotic properties and antimicrobial effects against foodborne bacterial pathogens. A total of 88 honey samples were colle...
