ABSTRACT From 2002 to 2008, there was a significant increase in extended-spectrum beta-lactamase (ESBL)-positive Escherichia coli isolates in European intra-abdominal infections, from 4.3% in 2002 to 11.8% in 2008 (P < 0.001), but not for ESBL-positive Klebsiella pneumoniae isolates (16.4% to 17.9% [P > 0.05]). Hospital-associated isolates were more common than community-associated isolates, at 14.0% versus 6.5%, respectively, for E. coli (P < 0.001) and 20.9% versus 5.3%, respectively, for K. pneumoniae (P < 0.01). Carbapenems were consistently the most active drugs tested.

O conhecimento das enterobactérias presentes em Gavião-carijó pode trazer uma compreensão sobre as doenças infecciosas que podem acometer essa ave, como também outros animais e/ou humanos, além de trazer mais informações sobre essa espécie de grande importância ecológica. Desta forma, o objetivo do estudo foi determinar as enterobactérias presentes na cloaca de Gaviões-carijós cativos e seu perfil de susceptibilidade a antimicrobianos. Inicialmente, foram coletadas amostras cloacais de nove espécimes com o auxílio de swabs. As amostras foram plaqueadas em ágar MacConkey, ágar Hektoen, ágar EMB e ágar SS e incubadas por 24 h a 35°C. Após incubação, as colônias foram submetidas às provas bioquímicas para confirmação da presença de enterobactérias. Posteriormente, o perfil de susceptibilidade das bactérias frente a agentes antimicrobianos foi avaliado através do teste da difusão em disco de acordo com o Clinical and Laboratory Standards Institute (CLSI). Escherichia coli (77,8%), Klebsiella oxytoca (11,1%), Klebsiella pneumoniae (11,1%) e Salmonella spp. (55,6%) foram isoladas das amostras coletadas. Dentre as cepas isoladas, algumas apresentaram resistência a até três antimicrobianos. O presente estudo trouxe um maior conhecimento sobre as enterobactérias presentes no Gavião-carijó (Rupornis magnirostris), mostrando um percentual significativo de enterobactérias de importância na saúde pública, evidenciando também a ocorrência de cepas com perfil de resistência a agentes antimicrobianos.

Abstract Objectives To assess the impact of ESBL production on mortality and length of hospital stay (LOS) of community-onset infections due to Escherichia coli or Klebsiella pneumoniae. Methods A population-based cohort study including all adult patients hospitalized with a first-time community-onset E. coli or K. pneumoniae bacteraemia or urinary tract infection in the North Denmark Region between 2007 and 2017. For each bacterial agent, we computed 1 year Kaplan–Meier survival curves and cumulative incidence functions of LOS, and by use of Cox proportional hazard regression we computed HRs as estimates of 30 day and 1 year mortality rate ratios (MRRs) and LOS among patients with and without ESBL-producing infections. Results We included 24 518 cases (among 22350 unique patients), of whom 1018 (4.2%) were infected by an ESBL-producing bacterium. The 30 day cumulative mortality and adjusted MRR (aMRR) in patients with and without ESBL-producing isolates was as follows: E. coli bacteraemia (n = 3831), 15.8% versus 14.0%, aMRR = 1.01 (95% CI = 0.70–1.45); E. coli urinary tract infection (n = 17151), 9.5% versus 8.7%, aMRR = 0.97 (95% CI = 0.75–1.26); K. pneumoniae bacteraemia (n = 734), 0% versus 17.2%, aMRR = not applicable; and K. pneumoniae urinary tract infection (n = 2802), 13.8% versus 10.7%, aMRR = 1.13 (95% CI = 0.73–1.75). The 1 year aMRR remained roughly unchanged. ESBL-producing E. coli bacteraemia was associated with an increased LOS compared with non-ESBL production. Conclusions ESBL production was not associated with an increased short- or long-term mortality in community-onset infections due to E. coli or K. pneumoniae, yet ESBL-producing E. coli bacteraemia was associated with an increased LOS.

Aims: The objective of the study was to ascertain the antimicrobial susceptibility pattern and ESBL prevalence of bacteria isolated from snacks. Place and Duration of Study: Department of Microbiology (Laboratory Unit) Michael Okpara University of Agriculture Umudike. Methodology: The snacks were mashed aseptically, serially diluted and inoculated onto nutrient agar and MacConkey agar. Isolates were identified using standard microbiological procedures. Antimicrobial susceptibility of the isolates and ESBL detection was done using disk diffusion method. ESBL production was confirmed using Double Disc Synergy Test (DDST) method following CLSI recommendations. Results: Escherichia coli, Salmonella Typhi, Staphylococcus aureus and Klebsiella pneumoniae were the bacteria isolated with Escherichia coli as the most prevalent isolate with 42% occurrence in the samples screened. There was significant difference in the sensitivity of the bacteria isolates to the different antibiotics used at P=0.05. Salmonella Typhi isolates exhibited highest resistance to an antibiotic with 86% resistance to ciprofloxacin while Klebsiella pneumoniae isolates exhibited the lowest resistance to an antibiotic with 10% resistance to cefotaxime. Among the Gram-negative bacteria, 36% of suspected ESBL producing E. coli isolates were confirmed as ESBL producers indicating the highest occurrence. Conclusion: The study confirmed the presence of bacteria in street vended snacks which exhibited high resistance to antibiotics that could be attributed to the presence of ESBL producers among the isolates.
