71 samples of milk and dairy products were collected from 18 cities throughout Iran. 93 strains of lactic acid bacteria (LAB) were isolated and assayed against four opportunistic patho gens including E. coli, proteus and klebsiella as gram-negative and S. aureus as a gram-positive organism. All indicators (organisms) were hospital strains. Among isolated bacteria, lactobacilli (37 isolates)...

Ten new azo Schiff bases 5a-h and 7a-b were prepared in excellent yields via the condensation of different aromatic amines and a new azoaldehyde, 2-hydroxy-3- methoxy-5-(4-methoxyphenylazo)benzaldehyde (4) by two different methods. All new compounds were tested against five microorganisms: Staphylococcus aureus (Gram positive and methicillin resistant), Bacillus subtilis (Gram positive), Kelebs...

This study was designed to investigate the antimicrobial activity of Cinnamomum iners standardized leave methanolic extract (CSLE), its fractions and isolated compounds. CSLE and fractions were subjected to disc diffusion, minimum inhibitory concentration (MIC) and minimum bactericidal concentration (MBC) tests using different Gram positive and Gram negative bacteria and yeast. Within the serie...

OBJECTIVES To evaluate the conjunctival bacterial flora in diabetic patients and nondiabetic subjects. MATERIALS AND METHODS Fifty-three diabetic patients and 43 nondiabetic healthy individuals were included in the study. A specimen was taken from each participant for the study by rubbing a sterile cotton-tipped swab on the inferior palpebral conjunctiva of the right eye. Samples were incubat...

introduction: aloe vera compounds have inhibitory activity on fungi, bacteria, and viruses. this study examines the antibacterial activity of a. vera purified extracts including gel, boiled skin, boiled gel, and distilled extract against pathogenic bacteria, staphylococcus aureus, methicillin-resistant s. aureus (mrsa), klebsiella pneumonia and pseudomonas aeruginosa were elucidated. method: th...

Introduction: Mastitis is an inflammatory condition of the breast and since it is usually associated with lactation , it is usually called lactational mastitis. Two major causes of mastitis are milk stasis and infection. The aim of this study was to evaluate bacterial mastitis in lactating women and to determine the sensitivity pattern of the involved bacteria. Method: A total of 203 milk sampl...

Endophthalmitis is a rare, but serious, postoperative complication of cataract surgery. It can have a devastating consequence on a patient’s vision: some patients may lose all light perception. The incidence of endophthalmitis has been reported to be between 0.13% and 0.7%.1 The primary source of this intraocular infection is considered to be bacteria from the patient’s ocular surface (cornea, ...

Introduction: A great interest regarding 2% chlorhexidine solution is over its efficiency on gram-negative bacteria, but chlorhexidine sensitive microorganisms include gram-positive bacteria, gram-negative bacteria and fungi. The aim of the study was to analyze the antimicrobial and antifungal action of 2% chlorhexidine solution against the microorganisms isolated from infected root canals befo...
