[Bacteremia and endarteritis cases secondary to Campylobacter spp. in a metropolitan hospital: our experience along a quarter of a century].

Six cases of bacteremia and one of endarteritis were identified between 1986 and 2010 in a general hospital in Chile. Five of these cases occurred during the second half of this timeframe, Campylobacter fetus predominated (5 out of 7) and the majority of the infections presented during warmer months. The mean age was 32.

[Respiratory infections caused by metapneumovirus in elderly patients].

Human metapneumovirus infections are increasingly recognized among adult patients and the aim of this report is to present a series of 4 cases admitted during the winter of 2010. All were detected by direct fluorescence anti-bodies assay of respiratory samples and all were female patients with an age range of 79 to 95 years, including two bedridden cases, one with dementia and three with chronic obstructive pulmonary disease. One patient presented with parainfluenza 3 virus coinfection.

[Risk factors associated to vancomycin-resistant enterococccus colonization in the Army Hospital in Santiago].

Since the appearance of Vancomicin-resistant enterococci (VRE) in our country, the Chilean Ministry of Health recommended the surveillance of intestinal colonization in patients in critical wards. We report the results of surveillance in ICU and onco-hematological wards from 2002 to 2008, with analysis of possible risk factors: demographical data, use and type of antibiotic, days of hospitalization prior to sampling, and year of hospitalization. Colonization rate increased from 0.

[Vibrio parahaemolyticus bacteremia: case report and literature review].

Vibrio parahaemolyticus is a facultative anaerobic gram negative rod responsible of sea food-associated diarrhoea. Although less common, it also causes wound infections and bacteraemia. We present a case of bacteraemia by this agent and a review of the literature.

[Multicenter study on the monitoring of in vitro susceptibility to tigeeyeline in Santiago, Chile].

The objective of this multicenter study was to determine tigecycline susceptibility rates, measured by agar diffusion, in nine hospitals in Santiago and to compare these rates with other antimicrobials. Each center studied 20 strains per month. All intermediate and fully resistant strains as well as 10% of susceptibile strains were also studied by the broth microdilution method.

[Presence of metallo beta-lactamases in imipenem-resistant Pseudomonas aeruginosa].

Background: Metallo-beta-lactamases (MBL) confer high resistance to carbapenems in Pseudomonas aeruginosa (Psae). They are encoded in mobile elements of different genes (VIM, IMP, SMP, GIM), along with other resistance genes.

Aim: To detect the presence of MBL in imipenem resistant Psae strains.

[Neonatal meningitis caused by atypical Streptococcus pneumoniae: case report and review].

Streptococcus pneumoniae is a rarely recognized cause of neonatal sepsis and/or meningitis, but it is associated with substantial morbidity and mortality. Traditionally, S. pneumoniae is identified in the laboratory by demonstrating susceptibility to optochin.

[In vitro activity of telithromycin against community acquired respiratory pathogens].

Background: Telithromycin is a new ketolide antimicrobial, that can be useful for the treatment of respiratory infections.

Aim: To compare in vitro activity of telithromycin against respiratory pathogens, isolated in outpatient clinics.

Material And Methods: Two hundred eighty strains isolated from patients with respiratory infections, were studied.
