“…En relación a la resistencia a antimicrobianos, destaca la ausencia de resistencia a V, hallazgo similar a lo descrito en otros trabajos 15 . Esta situación puede deberse al uso restringido de V y por otro lado, su uso en el Hospital Regional de Antofagasta está orientado al tratamiento de los pacientes con condiciones de gravedad.…”

“…El gen aceI codifica para una adhesina que es capaz de interactuar con el colágeno tipo I y IV y la laminina, favoreciendo la unión de enterococos a las células del hospedero 13 . En estudios anteriores, hemos aislados cepas de E. faecalis de origen clínico y ambiental, las cuales presentaban ausencia de resistencia a vancomicina, pero exhibían resistencia de alto nivel a aminoglucósidos 14,15 . Este trabajo tiene como objetivo estudiar la presencia de genes de virulencia en diferentes fenotipos bioquímicos de E. faecalis susceptibles y resistentes a aminoglucósidos.…”

“…Continuous surveillance is necessary to know if the transmission of these bacteria occurs via the food chain or is generated in the environment. 16 Immunosuppressed patients are those who can develop hospital-acquired infections due to strains of E. gallinarum and E. casseliflavus, causing bacteremia, endocarditis, septicemia, or urinary tract infection. 17 The danger of acquiring an infection from one of the strains isolated in this work is that some are resistant to antibiotics for human clinical use, as is the case with a strain of E. faecalis resistant to erythromycin, tetracycline, chloramphenicol, and rifampicin.…”

“…It is interesting to highlight that, in the literature, they refer to the importance that Enterococcus has acquired in recent times with respect to the high level of resistance to aminoglycosides, since they are intrinsically resistant at a low level. For example, in one study 16 they detected strains of E. faecalis (68%) and E. faecium (88%) resistant to gentamicin and both species 100% resistant to streptomycin, an important finding, since these strains were recovered from sewage, hence the importance of studying environmental bacteria and their resistance profiles.…”

Lettuce is one of the most common crops in the world, with high index of vitamins, minerals and fiber. Raw food consumption is closely related to foodborne illness, of which Escherichia coli O157:H7, seems to be the prime perpetrator leading to undesirable consequences. However, E. coli is not the only microorganism that can be transmitted, as reports validating the involvement of Aeromonas, Yersinia, Listeria, Staphylococcus, Campylobacter, and Salmonella have surfaced. The objective of this work was to detect the contamination of lettuces of different species acquired in several places of Cumaná, with Enterococcus strains. Of 52 lettuces acquired in food retail centers, 38% were contaminated with Enterococcus spp., strains. The best-selling lettuce was Lactuca sativa L. (25/52), but the most contaminated was Lactuca sativa var. capitata (89%). The highest average for Enterococcus was obtained in lettuces from Municipal Market. The dominant species of Enterococcus were E. faecalis (40%), and E. casseliflavus (30%); and to a lesser extent E. faecium (15%), E. gallinarum (10%), and E. avium (5%). The susceptibility profile showed that there are strains resistant to glycopeptides, fluoroquinolones, ansamycins, macrolides, phenols and tetracyclines. The clonal dissemination of two strains of E. faecalis and one strain of E. faecium by antibiotyping was demonstrated in lettuces from the municipal market. These results demonstrate that the food chain is a route of dissemination of multidrug resistant Enterococcus to the human intestinal microbiota, turning the gastrointestinal tract into a reservoir of intractable bacteria with the available antibiotics.

“…Algunos estudios efectuados en el norte del país con cepas de Enterococcus sp de diferentes muestras clínicas, recolectadas hacia el 2002, no señalan detección de aislados resistentes a vancomicina 10 . Sin embargo, este mismo grupo logró demostrar la circulación de aislados de Enterococcus sp, con resistencia intermedia a vancomicina, en aguas servidas de la ciudad de Antofagasta 11 .…”

Emergency of vancomycin-resistant Enterococcus infections in a teaching hospital in Chile An active surveillance of vancomycin-resistant enterococci (VRE) intestinal colonization in selected group of patients has been developed in Chile since year 2000. Nevertheless, no reports of clinical cases have been published. Aim. To describe main clinical and microbiological features of patients infected by VRE in a tertiary-level teaching Hospital. Patients and methods. Intestinal and clinical samples positive to VRE were provided by laboratory, and a retrospective analysis of potential risk factors, clinical features, treatment and outcomes was performed. Study encompassed years 2001 to 2006. Main results. 23 cases of infections were identified, all cases occurring during 2005 and 2006. Incidence rate was 0.07 and 0.09 cases per 1000 occupied bed-days, respectively. The mean age was 62.0 ± 17 years. A significant proportion of patients had cancer (39.1%), recent surgical procedures (54.1%), were on dialysis (26.1%), or were using steroids (26.1%). Most patients had received 2 or more antimicrobial (87%), almost a third represented transfers from other hospitals and an additional 22% readmissions before 30 days of latest discharge. Patients were mainly hospitalized in the ICU (60.9%) but nearly 30% were associated exclusively to nephrological or onco-hematological wards. Clinical manifestations included bacteremia (30.4%), surgical site infections or abscesses (26.1%), urinary tract infections (26.1%) and others.. Three patients (13%) did not have symptoms. After identification was possible, all isolates were identified as E. faecium (82.6% of total), the rest as Enterococcus sp. Most strains showed intermediate susceptibility to vancomycin (66.7%). For 14 strains studied both with vancomycin and teicoplanin, , phenotype Van B was predominant (85.7%), followed by VanA (7.1%) and VanB/VanD type (7.1%). No molecular studies were performed. Fifteen patients (65.4%) received a surgical and/or medical treatment. A favorable response was observed in 80% of these cases. Eight patients were not treated (34.8%), in 2 cases because of a rapidly-fatal infection. The global risk-fatality ratio for VRE infections was 13% and increased to 42.9% in patients with bacteremia. Microbiological eradication was documented in 52.2%.
