Arcobacter cryaerophilus group 1B, a gram-negative, curved or helical bacillus primarily known as a bovine and porcine pathogen, was isolated from the blood of a uremic patient with hematogenous pneumonia. The patient was treated successfully with ceftizoxime and tobramycin.

Capnocytophaga organisms are capnophilic, gram-negative bacilli that have been associated with infections deriving from the flora of the oropharynx. We report a case of inguinal adenitis caused by Capnocytophaga species that probably represents sexual transmission of the pathogen.

Dendritic cells (DCs) are critical in host defense against infection. DC depletion is an early event the course of sepsis that may impair mechanisms. Here, we addressed whether and dysfunction pathogen-independent, mediated via pattern recognition receptors, due to impaired development upon systemic infection with Gram-negative bacterium Escherichia coli Gram-positive pathogen Staphylococcus au...

BACKGROUND Gram negative infection is a major determinant of morbidity and survival. Traditional teaching suggests that burn wound infections in different centres are caused by differing sets of causative organisms. This study established whether Gram-negative burn wound isolates associated to clinical wound infection differ between burn centres. METHODS Studies investigating adult hospitalis...

During the last two decades, various medicinal plants have been studied for their possible antimicrobial activity to discover new antimicrobial agents capable of resolving problems such as the development of drug resistance in pathogenic microorganisms as well as the side effects of some present antibiotics. In this study, the antibacterial activity of methanolic extract of T. pubescens (rich i...

Current pathogen detection systems lack the stability, sensitivity, and time-independent functionality required for real-time biosensing in the field. Antibodies exhibit specificity for pathogenic bacteria but lack the sensitivity to detect reduced pathogen levels and the stability needed for detection in harsh environments. We are investigating naturally occurring antimicrobial peptides (AMPs)...

the nosocomial infections, caused by multi-drug resistant bacteria, are the most important cause of mortality throughout the world. one important mechanism against beta-lactam antibiotics is the production of beta-lactamases. enterobacteriaceae and non-fermentative bacteria, like pseudomonas aeruginosa and acinetobacter baumannnii may produce these enzymes. currently, there is no vaccine to pre...

conclusions with regards to the continuous changing in causative microorganisms isolated from patients with uti and antibiotic sensitivity patterns, it is recommended that bacterial sensitivity patterns in populations are determined in any region annually. . objectives this study aimed to detect and also compare the frequency and drug resistance pattern of gram negative bacteria isolated from p...

antibiotic resistance of intensive care unit (icu) born aerobic gram-negative bacteria was evaluated during a six months period at a teaching hospital in tehran, and determination of the validity of the results obtained from disc diffusion tests, using discs manufactured in iran. disc susceptibility tests using iranian and standard discs (diffusion discs available in international markets) were...
