We evaluated the bactericidal activities of 35 benzaldehydes, 34 benzoic acids, and 1 benzoic acid methyl ester against Campylobacter jejuni, Escherichia coli O157:H7, Listeria monocytogenes, and Salmonella enterica when these compounds were substituted on the benzene ring with 0, 1, 2, or 3 hydroxy (OH) and/or methoxy (OCH3) groups in a pH 7.0 buffer. Dose-response plots were used to determine...

Introduction: Breast milk health is one of the most salient elements in feeding of premature infants. Generally in initial of breast feeding, different methods of disinfecting such as irrigation with usual detergents like water and soap are used to eliminate the probable bacteria.  The necessity  of  the  usage  of  such  items  has  not  been  mentioned  in  some  studies, and  even at the tim...

Abstract Background and Aims Ralstonia (RB) Burkholderia (BB) species are environmental Gram-negative bacilli responsible for several nosocomial infections in immunocompromised or frail patients. RB BB may contaminate medical devices because of their ability to survive a biofilm with low nutrient requests. Reports infection outbreaks due very few only sporadic cases, the source contamination wa...

Objective: The potential for increased risks of infection is an important concern with water births. We performed microbiological analyses on water samples taken from birthing pools before and after water births, and compared the rate of neonatal infection arising after water births with that arising after conventional delivery. Materials and Methods: In this prospective observational study beg...

introduction: indoor swimming pools are the most important recreational centres. swimming pool water is responsible for the transmission of parasitic diseases. this study was performed to determine the rate of parasitic contamination and some physio- chemical parameters of indoor swimming pools in urmia during 2002. materials and methods: this study was a descriptive-cross sectional one in whic...
