The results of a rapid, direct blood culture disk susceptibility test indicated that antimicrobial chemotherapy should be changed in 48 of 173 patients with bacteremia. In 32 patients (66.6%), the indicated change was made approximately 24 h sooner than if conventional, nonrapid susceptibility tests had been used to guide therapy.
Determining the susceptibility of pathogens to antibacterial substances is one key steps in bacteriological diagnostics that affects success both therapeutic therapy and appropriate selection cosmetic products. Antibiotic chemotherapeutic sensitivity tests determine ability an antimicrobial agent inhibit growth a microorganism vitro.
OBJECTIVE To compare in-vitro antimicrobial susceptibility of nitrofurantoin against commonly used antimicrobials for the treatment of urinary tract infection caused by enterococci. METHODS A total of 144 enterococci (Enterococcus faecalis, n=130, Enterococcus faecium, n=14) isolated and confirmed by biochemical tests at the department of Microbiology, Armed Forces Institute of Pathology, Raw...
PURPOSE A significant barrier to efficient antibiotic management of infection is that the standard diagnostic methodologies do not provide results at the point of care. The delays between sample collection and bacterial culture and antibiotic susceptibility reporting have led to empirical use of antibiotics, contributing to the emergence of drug resistant pathogens. As a key step toward the dev...
Broth dilution antimicrobial susceptibility tests and biochemical identification of Bacteroides fragilis subspecies were performed by micromethods, yielding results within 48 to 72 h of isolation. The subspecies had similar minimal inhibitory concentration end points.
abstract background and objective: due to the continuous increase of multidrug-resistant acinetobacter baumannii strains around the world, decision making for an effective treatment of infections caused by this organism depends on the results of antimicrobial susceptibility tests. in this study, the validity of disk diffusion and e-test methods was assessed by their comparison with the re...
Abstract Introduction: Klebsiella pneumoniae is an opportunistic pathogen that causes urinary tract Infection (UTI), intra-abdominal infection and pneumonia in patients with weakened immune systems or underlying diseases. Several studies have shown that the indiscriminate and irregular use of antibiotics can cause antibiotic resistance. Antimicrobial resistance has been introduced as one of ...
Actinomadura madurae is an aerobic actinomycete which is best known worldwide as the cause of actinomycotic mycetomas. It has not previously been reported to have caused invasive pulmonary or disseminated infection in humans. We describe an AIDS patient with opportunistic A. madurae-induced pneumonia and bacteremia. The isolate from the patient's blood was subjected to dilutional antimicrobial ...
Background: The antibiotic resistance is considered as one of the biggest public health concerns in most countries. The aim of this study was to determine antibiotic resistance pattern of Escherichia coli isolated from chickens with colibacillosis in Yazd, Iran. Methods: A total of 200 carcasses of Ross chickens with colibacillosis were collected from farms located around Yazd, central Iran. A...
Standard antimicrobial susceptibility tests used to determine bacterial susceptibility to antibiotics are growth dependent and time consuming. The long incubation time required for standard tests may render susceptibility results irrelevant, particularly for patients infected with lethal bacteria that are slow growing on agar but progress rapidly in vivo, such as Yersinia pestis. Here, we prese...
