conclusions flushing dental unit waterlines are an effective measure in reducing the number of bacterial contaminants. results bacterial contamination was found in all 24 units at the beginning of daily activity with a mean colony count of 17850. the number of colonies decreased to 3250 following 30 seconds of flushing in 16 units and later to 1837 after flushing for two minutes in 13 units. in...

Bacterial invasion of dental unit water lines is a global issue, which if left untreated, leads to formation bacterial biofilm within the lines. The aim this study was determine number colony forming units (CFU) in waterlines Rehman college dentistry. Samples from air-water syringes 44 different various departments hospital were collected. Tip each syringe heated using direct flaming eliminate ...

Introduction & Objective: The aim evaluate the relationship between salivary cortisol and viable count of mutans streptococci. in abuse patient.by using cobass device to determine level of salivary cortisol in two group and count colony of bacteria mutans streptococci (CFU/ml) by identification and culturing method. Methods: This study included a sample of 86 participants  aged 17–30 years old...

Patients with idiopathic, cyclic, and congenital neutropenia have recurrent severe bacterial infections. One hundred twenty-three patients with recurrent infections and severe chronic neutropenia (absolute neutrophil count < 0.5 X 109/L) due to these diseases were enrolled in this multicenter phase 111 trial. They were randomized to either immediately beginning recombinant human granulocyte col...

Urinary and serum colony-stimulating factor (CSF) levels were measured in 11 patients with chronic idiopathic neutropenia without infections and in 10 normal individuals. Urinary CSF output was determined using mouse marrow target cells, and serum CSF activity was assayed with human marrow target cells by the double agar layer technique. Using these methods, there was no significant difference ...

Methods Following a standardized physical exam using sterile gloves and a sterile stethoscope, bacterial contamination of the following regions were assessed using contact plates: stethoscope diaphragm, stethoscope tube, fingertips, thenar region, hypothenar region and back of physician’s dominant hand. Total aerobic colony count (ACC) were determined on digital photographs using a counting tool.

BACKGROUND Pyuria is universally considered as essential for identifying urinary tract infections in noncatheterized patients. The utility of pyuria in the catheterized patient, to identify catheter-associated urinary tract infection (CAUTI), has not been adequately defined. METHODS We prospectively studied 761 newly catheterized patients in a university hospital; 82 (10.8%) developed nosocom...

A survey of 1,228 patients was conducted for the evidence of urinary infection by culture and colony count. Of these patients, 50 percent were from the hospital population while the other half were domiciliary. Sixty percent of the ward patients were found to have significant bacterial count as against 35.2 per cent of the domiciliary patients. The commonest organism isolated from the ward pati...

background: it is estimated that about 50% of causes of recurrent pregnancy loss (rpl) cases remain unknown. sperm factors are suggested to have probable role in cases with rpl. objective: the goal was to determine the possible relationship between semen bacterial contaminations with unexplained rpl. also, the correlation between number of bacterial colony and sperm chromatin condensation was e...
