abstract introduction: septicemia is an important and common cause of neonatal mortality and morbidity. several factors such as genetic, social, hygienic and nutritional factors are effective on the frequency of bacterial pathogens in neonatal septicemia, several studies have performed to determine common pathogens in the different parts of the world. objective: comparison of neonatal bacterial...

OBJECTIVE Bacterial sepsis continues to be a major cause of morbidity and mortality in newborns. Bacterial pathogens of neonatal septicemia may vary from one country to another and within a country from one hospital or region to another. Both gram-negative and gram-positive bacteria are responsible in neonatal sepsis. This study was undertaken to determine the prevalent bacterial agents of neon...

Oil contamination in Iran due to high application of oil compounds, is one of the most dangerous pollution factors. Bioremediation is one of principal strategies for remediation, where in the pollutants can be removed by use of microorganism or any biological process that uses microorganisms or their enzymes to return the environment altered by contaminants to its original condition. With regar...

Objective: The potential of marine crabs as a source of bioactive products is largely unexplored. Methods: Portunussegnis crabs were collected from the northern coast of Persian Gulf. Antimicrobial activities of hepatopancreas, hemolymph and proteins of hemplymph from P. segnis crabs against a range of 11 different bacterial and 6 fungal pathogen strains were examined. Two positive controls Amo...

IIce nucleation active (INA) bacteria are common epiphytic inhabitants that cause frost damage in many plants in the near-zero temperatures. Yet, no studies were found in ice nucleation bacteria associated with pistachio trees. In our earlier study some INA strains were identified and reported. These were assigned as Pseudomonas fragi, P. putida, P. moraviensis and<em...

Marine ornamental fishes are remarkably valuable due to their high demand in domestic and international markets. It is a growing global interest to maintain these fishes in captivity. The bacterial and fungal infection is the major drawbacks in captive condition. In the present study, in-vitro screening of organic solvent extracts (methanol and acetone) of green algae Halimeda micronesia were t...

INTRODUCTION American cockroaches, Periplaneta americana, are the most important pests in hospitals and dwelling environments. They are mechanical vectors of some bacterial pathogens. GOAL The present investigation was carried out in Ghods hospital and 5 dwelling localities of Paveh city to evaluate bacterial infestations of American cockroaches in this region of Iran. METHODS The samples w...
