This study investigated the prevalence of 19 virulence factors and biofilm production in 86 EAEC isolates causing diarrhea in children less than 5 years of age from Ifakara, Tanzania. Virulence factors were detected by PCR, whereas biofilm production was determined using a microtiter plate assay. No virulence factor, with the exception of the aat gene used(More)
Travelers' diarrhea is a major public health problem. From patients in whom diarrhea developed after travel to India, 5 enteroaggregative Escherichia coli strains carrying β-lactamase CTX-M-15 were identified; 3 belonged to clonal complex sequence type 38. This β-lactamase contributes to the multidrug resistance of enteroaggregative E. coli, thereby(More)
Leukotriene receptor antagonists, such as montelukast (MK), are currently used to treat rhinitis and asthma, but their anti-inflammatory role in eosinophil inflammation is not well understood. The aim of this study is to investigate the effect of MK on an in vitro model of upper-airway eosinophil inflammation by reducing pro-inflammatory cytokines from both(More)
Being able to recruit high-risk volunteers who are also willing to consider future participation in vaccine trials are critical features of vaccine preparedness studies. We described data from two cohorts of injection- and non-injection drug users in Barcelona, Spain [Red Cross centre] and in San Francisco, USA, [UFO-VAX study] at high risk of HIV/HCV(More)
The purpose of this study was to assess HIV risk and willingness to participate in HIV vaccine trials in three high risk populations in Spain. Eight hundred and forty-four participants, comprising female sex workers, injection and non-injection drug users (IDUs and NIDUs, respectively), and men who have sex with men were tested for HIV and surveyed for risk(More)
BACKGROUND Although antihistamines and topical corticosteroids are used in combination to treat allergic rhinitis, their additive effect has not been yet demonstrated. The aim was investigate the antiinflammatory additive effect of mometasone and desloratadine on cytokine and sICAM-1 secretion by epithelial cells, and on eosinophil survival stimulated by(More)
The potential for implementation of HIV vaccine trials in hard-to-reach female sex workers in an inner city area of Barcelona, Spain was assessed via a study of HIV risk, willingness to participate and the success of retention strategies. In 130 women, serological HIV status, behavioral risk exposures and willingness to participate in future HIV vaccine(More)
