nosocomial infection and its heavy financial cost is a well recognized problem. a variety of sources of organisms involved in nosocomial infection have been identified in recent years. one potential route of bacterial infection is contamination. in order to assess the importance of food contamination, we carried out a survey of bacterial examination of food and the kitchen environment of 14 hos...

The data presented in this paper emphasize the importance of eliminating bacterial contamination in studies of amino acid incorporation into isolated mitochondria. A correlation between the number of bacteria present and amino acid incorporation into mitochondria was observed when pure cultures of bacteria were added to mitochondria prepared under sterile conditions. Low concentrations of dinit...

EXPERIMENTAL SUBSTANTIATION OF SELECTING THE PRODUCT FOR SANITATION OF ABDOMINAL CAVITY IN ACUTE GENERALIZED PERITONITIS V.V. Boyko, V.K. Logachev, N.A. Remneva, M.E. Tymchenko, V.P. Nevzorov, O.A. Golovina The work has studied morphological and ultrastructural changes in the mesothelium of rat peritoneum and bacterial contamination after sanitation of abdominal cavity by 0.3% solution of H2O2 ...

Many factors have been shown to influence bacterial transfer between surfaces, including surface type, bacterial species, moisture level, pressure, and friction, but the effect of inoculum size on bacterial transfer has not yet been established. Bacterial cross contamination rates during performance of common food service tasks were previously determined in our laboratory using nalidixic acid-r...

Laboratory animal models are an important part of test design. Certain conditions such as microbial contamination in diets of these models could affect the results of experiments. One of the most important routes that predispose to contamination is generated through feeding of laboratory animals. This study aimed to show the effect of gamma irradiation in reducing bacteria concentrations,...

OBJECTIVES To compare three methods of intratubular contamination that simulate endodontic infections using confocal laser scanning microscopy (CLSM). MATERIAL AND METHODS Two pre-existing models of dentinal contamination were used to induce intratubular infection (groups A and B). These methods were modified in an attempt to improve the model (group C). Among the modifications it may be incl...

Bacterial contamination of blood components, particularly of platelet concentrates (PCs), represents the greatest infectious risk in blood transfusion. Although the incidence of platelet bacterial contamination is approximately 1 per 2,000 U, the urgent need for a method for the routine screening of PCs to improve safety for patients had not been considered for a long time. Besides the culturin...

BACKGROUND The use of convective air warming and/or cooling for the prevention of hypothermia or to induce hypothermia is growing rapidly. To date, there is no information available as to the potential risks for infection associated with either the post-surgical reuse or the repositioning of coverlets closer to the wound. We hypothesized that use of coverlets either intra- or postoperatively le...
