Abstract:

A breach of the skin barrier, due to a burn wound, facilitates colonization by various microorganisms. Burn wounds can become colonized from the patients’ own skin flora, respiratory tract, or with exogenous bacteria from the environment. Strategies to treat burn wound infections are multipronged: removal of the infected necrotic tissue, wound dressing to protect the damaged area, and treatment with specific antimicrobials to prevent reinfection. The development of chronic infections, which could potentially lead to sepsis, depends largely on how well the microorganisms form biofilms within th

Abstract:

Rapid and reliable antimicrobial susceptibility testing plays a vital role in deciding the appropriate antibiotic therapy prescribed. Current techniques employed by clinical laboratories include breakpoint tests and microdilution assays which typically provide susceptibility data after 18 to 24 hours. The primary aim of this study was to develop a reliable antimicrobial susceptibility test, using a tetrazolium-based salt as a colorimetric indicator ofbacterial metabolism, which could provide accurate susceptibility data within 4 to 5 hours.

Abstract:

Infectious diseases resulting from bacterial pathogens are the most common causes of patient morbidity and mortality worldwide. The rapid identification of the pathogens and their antibiotic resistances is crucial for proper clinical management. However, the standard culture-based diagnostic approach requires a minimum of two days from the initial specimen collection to result reporting. As a consequence, broad-spectrum antibiotics are often prescribed under the worst-case assumption without knowledge of the pathogens or their resistances. The current clinical practice results in improper trea

Abstract:

The prevention of healthcare‐associated infections (HCAIs) is a major challenge currently being faced by hospitals in both the UK and worldwide. The hospital environment acts as a reservoir for nosocomial organisms contributing towards the transmission of bacteria and thus the colonisation and infection rates of the patient population. Therefore, it is desirable to implement measures to decrease the microbial load within the hospital environment as a whole and particularly on frequently touched surfaces. Antimicrobial coatings could be applied to these surfaces, and used as an adjunct to other

For fast-growing organisms, plates are ready for counting 1-2 days post plating, while several weeks may be needed for slower growing organisms. Spirochetes, like B. burgdorferi are di

Abstract:

The seed germination process during sprout production provides suitable environmental conditions for the growth of pathogenic bacteria, such as Listeria monocytogenes.

Therefore, the objective of this study was to evaluate the antimicrobial susceptibility of L. monocytogenes to bacteriophage on alfalfa sprouts during seed germination and subsequent refrigerated st

Abstract:

Staphylococcus aureus is one of the leading causes of hospital acquired infections. The ability of S. aureus to acquire resistance to a diverse range of antimicrobial compounds, results in limited treatment options, particularly in methicillin-resistant S. aureus. A mechanism by which S. aureus develops reduced susceptibility to antimicrobials is through the formation of small colony variants (SCVs). Reduced antimicrobial susceptibility in S. aureus SCVs is not related to ‘classical’ mechanisms of resistance, but occurs as a direct result of the development of the SCV phenotype. S. aureus SCVs

Abstract:

O trato intestinal dos mamíferos constitui um reservatório natural de Enterococcus, bactérias oportunistas, ubiquitárias, frequentemente associadas a infeções nosocomiais multirresistentes em humanos, sendo Enterococcus faecium e Enterococcus faecalis as espécies mais importantes. Neste estudo foram identificadas as espécies de Enterococcus predominantes no conteúdo cecal de bovinos e suínos através de técnicas moleculares, tendo sido avaliados os perfis de suscetibilidade antimicrobiana das estirpes de E. faecium e E. faecalis pelos métodos de agar difusão e microdiluição, e identificados det

Abstract:

Se determinó la susceptibilidad antimicrobiana de 95 cepas de Salmonella sp aisladas a partir de muestras remitidas al laboratorio de microbiología pertenecientes al Laboratorio Bioservice, ante 18 antimicrobianos durante el periodo de diciembre 2012 a noviembre del 2014. La prueba de susceptibilidad antimicrobiana determinó que el 93.7% mostraron resistencia a Sulfametoxazol, el 82.1% a Eritromicina, el 71.6% a Sulfametoxazol/Trimetropim, el 50.5% a Ácido Nalidíxico y Furazolidona, el 37.9% a Ampicilina y Tetraciclina, 31.6% a Kanamicina, el 28.4%% a Gentamicina, 25.3% a Cloranfenicol, 20% a

Abstract:

O Brasil é líder mundial em exportação de carne bovina. A qualidade e a segurança dos produtos cárneos são essenciais para permanecer como exportador no competitivo mercado internacional. Atualmente, critérios microbiológicos são usados para avaliar produtos cárneos, e Salmonella tem sido usada como um importante indicador da segurança dos alimentos por diversos países. No presente estudo, um total de 120 carcaças foram analisadas em três diferentes pontos do processo de abate em um abatedouro-frigorífico exportador localizado no sul do Brasil. Os resultados demonstraram que quatro carcaças (3

Streptococcus dysgalactiae subsp. equisimilis (SDE), which can express any of these two Lancefield group antigens, is the GCGS species most commonly reported in human infection worldwide and may cause a number of p
