OBJECTIVE To determine the efficacy of 2.5% and 1.25% Povidone-Iodine solution for Ophthalmia neonatorum prophylaxis. STUDY DESIGN Interventional study. PLACE AND DURATION OF STUDY Eye Department, Combined Military Hospital, Sargodha, from May to November 2014. METHODOLOGY Atotal of 200 eyes of 100 newborn babies were enrolled and divided into two groups of 100 right eyes and 100 left eye...

Sinorhizobium meliloti growing on soft agar can exhibit an unusual surface spreading behaviour that differs from other bacterial surface motilities. Bacteria in the colony secrete an exopolysaccharide-rich mucoid fluid that expands outward on the surface, carrying within it a suspension of actively dividing cells. The moving slime disperses the cells in complex and dynamic patterns indicative o...

Aim The study evaluated the antibacterial effects of dental restorations such as nano-hybrid composite (Empress), a glass ionomer cement (GIC Gold label Type 9) and silver amalgam against Streptococcus mutans. Materials and Methods A modified bacterial suspension within the material assay was used to study the antibacterial effects. A volume of 20 μl of bacterial suspensions were placed in a ...

The effect of a series of redox indicators and systems has been tested with a suspension of luminous bacteria (B. fischeri) in M/4 phosphate buffer of P(H) = 7.6. The indicators behave as expected from their position in the redox series, the most positive being reduced rapidly even in presence of air and before luminescence of the bacteria disappears, those of intermediate position at the time ...

A major risk for astronauts during prolonged space flight is infection as a result of the combined effects of microgravity, situational and confinement stress, alterations in food intake, altered circadian rhythm, and radiation that can significantly impair the immune system and the body's defense systems. We previously reported a massive increase in morbidity with a decrease in the ability to ...

bacterial endocarditis is a serious disease that could occur after invasive dental procedures. despite a large number of papers written about the knowledge of prevention of bacterial endocarditis among health care workers in western countries, little is known about awareness of this subject among practitioners and students in other countries. the purpose of the present study was to assess the k...

Methods 1. Light microscopy of smears of organs and tissues of animals, bacterial suspension (Gram staining) the study of morphological and tinctorial properties of the pathogen. 2. Immunofluorescence method for detection of antibody (IFA) detection of tularemia bacterial cells using specific fluorescent immunoglobulin. 3. Biological method subcutaneous infection of laboratory animals (white mi...

Automated methods for measuring enzyme activities of bacterial suspensions in saline are described. The methods were applied to bacteria cultured from urine specimens, and specific enzyme profiles characteristic for Escherichia coli, Klebsiella sp, Proteus sp, and Pseudomonas sp were established. Identification of 294 freshly isolated strains by automated and conventional methods were compared....

To survive in harsh conditions, motile bacteria swim in complex environments and respond to the surrounding flow. Here, we develop a mathematical model describing how flagella bending affects macroscopic properties of bacterial suspensions. First, we show how the flagella bending contributes to the decrease in the effective viscosity observed in dilute suspension. Our results do not impose tumb...

Bacterial genes responsible for poly(3-hydroxybutyrate) (PHB) biosynthesis were targeted to plant peroxisomes by adding a carboxy-terminal targeting sequence. The enzymes evidently were transported into peroxisomes, retained their catalytic activity, and reacted with peroxisomally available precursors because PHB synthesis in transgenic plant cells was localized to peroxisomes. Up to 2 mg/g fre...
