Abstract:

Conventional antimicrobial susceptibility tests, including phenotypic and genotypic methods, are insufficiently accurate and frequently fail to identify effective antibiotics. These methods predominantly select therapies based on the antibiotic response of only the lead bacterial pathogen within pure bacterial culture. However, this neglects the fact that, in the majority of human infections, the lead bacterial pathogens are present as a part of multispecies communities that modulate the response of these lead pathogens to antibiotics and that multiple pathogens can contribute to the infection

SUMMARY Susceptibility tests were performed on milk samples representing prevalent mastitis infections in certain herds. Susceptibility patterns of the same bacterial species from several mastitis infections in the same herd were consistent. The herd antibiotic susceptibility profiles were used as a basis for selecting antibiotics for treatment of all such mastitis cases in that herd. A high degree of correlation was seen between the susceptibility test results and treatment results. Susceptibility patterns of the same bacterial species from mastitis infections in different herds varied greatl

Abstract:

Excessive and sometimes inappropriate use of antibiotics leads to the emergence of multidrug-resistant (MDR) strains. Antibiotic-resistant pathogens are a major public health problem in routine clinical practice and have severe economic consequences due to increased treatment costs. Timely testing of antimicrobial susceptibility for bacterial infections ensures accurate prescribing, reduces treatment time, and helps minimize the spread of antibiotic-resistant infections. The main problem with antibiotic susceptibility testing is that there are not enough fast diagnostic tests to allow appropri

The rise of antibiotic resistance is an emerging problem of the millennium.

Analyzing antibiotic susceptibility pattern of uropathogens help to overcome the therapeutic difficulties created by the rising antimicrobial resistant bacteria and guides in choosing appropriate antibiotics. Hence, we aimed at evaluating the pathogens causing UTI and study their antibiogram. Midstream urine samples were collected, cultured and appropriate biochemical tests were performed for proper identification of urinary pathogens in BSMMU from January 2013 to December 2013. The most common isolated Gram negative uropathogens were Escherichia coli (63.93%) followed by Klebsiella pneumoniae

Ralstonia pickettii and Ralstonia insidiosa are waterborne bacteria that can survive and grow in various water sources, and that are emerging pathogens in hospital settings. Not much is known about the antibiotic resistance of these bacteria. Previous reports of antimicrobial susceptibility have been largely limited to a few clinical strains with no accounting for genotypic or phenotypic diversity or that these species could vary from the set breakpoints. Etests and disc diffusion tests were carried out to compare the antimicrobial susceptibilities to 12 different antibiotics of 68 different i

The delayed treatment of pediatric periorbital cellulitis may have severe consequences.

All edwardsiellae were naturally sensitive to tetracyclines, aminoglycosides, most β-lactams, quinolones, antifolates, chloramphenicol, nitrofurantoin, and fosfomycin. Edwardsiella species were naturally resistant to macrolides, lincosamides, streptogramins, glycopeptides, rifampin, fusidic acid, and oxac

A bioterror event using an infectious bacterium may lead to catastrophic outcomes involving morbidity and mortality as well as social and psychological stress. Moreover, a bioterror event using an antibiotic resistance engineered bacterial agent may raise additional concerns. Thus, preparedness is essential to preclude and control the dissemination of the bacterial agent as well as to appropriately and promptly treat potentially exposed individuals or patients. Rates of morbidity, death, and social anxiety can be drastically reduced if the rapid delivery of antimicrobial agents for post-exposu

Background: Antibiotic resistance is a global challenge, particularly in urinary tract infections (UTIs) caused by Escherichia coli (E. coli), which is a leading pathogen in both nosocomial and community-acquired infections. Regular monitoring of antibiotic susceptibility profiles is essential due to the rising prevalence of drug-resistant bacteria. This study focused on evaluating the antibiotic susceptibility pattern of E. coli isolated from urine samples of patients attending Civil Hospital Madyan, Swat, to guide effective empirical therapy.
