OBJECTIVES This study was designed to determine the role of flushing dental water lines for the removal of heterotrophic plate count bacteria, Legionella spp., and free-living protozoa. METHODS Forty dental offices were surveyed in the study. An initial sample and a sample taken after three minutes of flushing were obtained from the air/water syringe at each location. All samples were quantit...

Total microbial count was highly affected (up to 61% at 1000 micrograms level) in presence of hexaconazole and persisted up to 21 days. Bacteria were more susceptible than actinomycetes. Carbofuran and ethion were moderately toxic to soil microflora. Inhibitory effects of all the three pesticides gradually decreased after 21 days as was evident by increase in total microbial count except in car...

A cotton textile dried with various hygroscopic salts then contaminated with Staphylococcus epidermidis and dried again, showed remarkable reduction in viable bacterial cells. Of the salts investigated, sodium acetate was found to have the greatest antibacterial effect. Calcium chloride, magnesium chloride and magnesium sulfate, also showed some antibacterial effect. For sodium acetate, drying ...

The objective of present work was to determine and compare the components of bioaerosol in several sectors of plant processing industries. The study was conducted in 10 facilities engaged in herb and grain processing, flax threshing, grain storing, baking, and cereals production. The air samples were taken on glass fibre filters with an AS-50 sampler. We determined the concentrations of airborn...

Chicory plant (Dorema aucheri) belongs to Asteraceae family and contains flavonoids. Milk is a mixture of protein, fat, lactose, minerals. This research carried out in order to evaluate the effect of chicory plant on the activities of bifidobacterium bifidum and lactobacillus acidophilus. Four containers containing a liter of 1.5 % sterilized skim milk were s...

To survive in natural waters, bacteria must respond to variety of environmental factors. Flexibacter survival in the aquatic environment is influenced by number of parameters, such as temperature, heavy metal concentration and oxidation. Here we investigate the influence of these factors on the survival of Flexibacter chinensis in starvation medium. Our data shows that different concentrations ...

STUDY DESIGN Prospective experimental study. PURPOSE To evaluate bacterial contamination during surgery. OVERVIEW OF LITERATURE The participants of surgery and ventilation system have been known as the most significant sources of contamination. METHODS Two pairs of air culture blood agar plate for G(+) bacteria and MacConkey agar plate for G(-) bacteria were placed at 3 different location...

The effects of whey protein (12%) and sodium alginate (0.5%) on chemical, microbial and sensory changes and shelf life in kilka during frozen storage are investigated for up to 6 months. Total bacteria count and Staphylococcus bacteria counts(2 / 51 and 1 / 44 log CFU/g) in coated samples showed decrease in comparison with control samples(3.21- 2.28 log CFU/g). Moisture of coated samples had s...

 Cypermethrin is a potential toxic pollutant that directly threatens the aquatic ecosystems and environment. Propolis, a natural product collected from plants by honey bees has many functions, such as antimicrobial, antioxidant, and anti-inflammatory. This study attempted to detrmine some biochemical and microbiological parameters of rainbow trout fillets after exposure to propolis an...

1251 urincs were examined and iii each case the three following criteria were studied 1_ presence of pus cells in wet mount (4 or more hpf). 2_ isolation of pathogenic bacteria  :j_ presence of 10,000 or more bacteria per c.c. of urine 801 specimens were obtained from patients referred to the diagnastic iaboratorv of institute of public health research. and 450 specimens were collected from hea...
