The algorithm for a new identification system was designed on the basis of colony color and morphology on CHROMagar Orientation medium in conjunction with simple biochemical tests such as indole (IND), lysine decarboxylase (LDC), and ornithine decarboxylase (ODC) utilization tests with gram-negative bacilli isolated from urine samples as well as pus, stool, and other clinical specimens by the f...

Background Inflamed epidermal cysts are common clinical conditions, and they frequently form abscesses. We designed a study to delineate the bacteriology of inflamed epidermal cysts. Methods We enrolled 61 adult patients with inflamed epidermal cysts characterized by surface erythema, with or without tenderness, or localized abscess formation within the cyst cavity. Incision and drainage of the...

The discharge of untreated detergent-bearing waste introduces linear alklcylbenzene sulfonates (LAS) to the aquatic environment. The surfactant persists in some streams and rivers in Nigeria, some is adsorbed to suspended materials and end in the sediment of the receiving water bodies. In this study, bacteria isolated from sediments of some tropical detergent-effluent-polluted streams were test...

SIR—We read with great interest the report by Raguin et al. [1] on Shigella boydii as a possible causative agent of colonic malacoplakia in an HIV-infected patient. In the absence of positive cultures, S. boydii was identified by means of universal bacterial 16S rDNA–based amplification and sequencing. Since malacoplakia is usually caused by Escherichia coli, a close relative of shigellae and g...

Due to cholestasis or adverse drug effects, the excretion of bilirubin conjugates can decrease; therefore, the level of bilirubin (B) and bilirubin glucuronides (BGs) increases in the serum with the concomitant shift of bilirubin diversus monoglucuronide (BDG/BMG) equilibrium. The aim of this study was to utilize the collagen-sandwich culture of hepatocytes as an in vitro model for studying B c...

| This study was undertaken to estimate the prevalence and antimicrobial susceptibility of gram negative bacteria (GNB) recovered from dairy cows with subclinical mastitis (SCM) with detection of β-lactamase encoding genes, sulphonamide encoding gene and intergron classes by polymerase chain reaction (PCR). In total, 180 cow’s milk samples were collected from three different dairy farms. Milk s...

OBJECTIVE To study the bacterial pathogens causing neonatal sepsis and their sensitivity pattern so that guidelines can be prepared for empirical antibiotic therapy. SETTING The study was conducted in the neonatal intensive care unit (NICU) at PNS Shifa (Naval Hospital), Karachi during January 1997 to June 1999. METHODS Blood specimens for culture were drawn from 520 newborns admitted in a ...

Vi khuẩn và nấm phân giải cellulose càng trở nên quan trọng hơn do có nhiều ứng dụng trong đời sống, đặc biệt hủy chất thải giàu sản xuất hữu cơ. Từ 6 tổ mối thu nhận ở huyện Bình Tân, tỉnh Vĩnh Long đã lập được 28 chủng vi 7 đều khả năng CMC (carboxymethyl cellulose), đó các đạt hiệu quả cao gồm 1BTL6 (61,7%), 3BTT6 (65,8%), 2BTNT5 (61,5%) 1BTNT3 (60,4%). Thêm vào đó, từ rơm tạo đường glucose ...

background and objectives : resistance among bacterial isolates is the leading cause of increased mortality and morbidity worldwide. carbapenems once thought to be effective are becoming ineffective mostly due to the emergence of carbapenemase. this study was designed to determine in vitro efficacy of modified hodge test for detection of carbapenemase production in gram negative rods. material ...
