INTRODUCTION Acinetobacter baumannii and Brucella species are Gram-negative organisms that are vulnerable to misinterpretation as Gram-positive or Gram-variable in blood cultures. OBJECTIVE We assess the random errors in gram stain interpretation to reduce the likelihood of such errors and therefore patient harm. METHODOLOGY Aerobic and anaerobic blood cultures from two patients in an acute...

background : this study aimed to compare three staining methods including: calcofluor white, chromotrope and quick hot gram chromotrope used in diagnosis of intestinal microsporidial spores . methods : one hundred and seventy five stool specimens were collected from patients referred to laboratory of intestinal protozoology at the school of public health, tehran university of medical sciences d...

Yogurt and kefir are well-known fermented dairy products that provide many benefits to human health. Microorganisms contained in yogurt play an important role produce bioactive metabolites, including eradicating pathogens. This study presents the antimicrobial activity of 12 strains isolated from samples obtained Malang, Indonesia. Strain K3 shows highest with diameter inhibitory zone was 8.11±...
