Pulsed-field gel electrophoresis fingerprints of 98 Campylobacter jejuni isolates from patients (85) and chicken carcasses (13) in Hong Kong in 2002 demonstrated high genetic diversity. The prevalence of quinolone resistance among the isolates was 85.9%, and replacement of the threonine-86 residue in the gyrase subunit A was the major resistance mechanism.
AIMS The aim of this study was to characterise clinical and microbiological features of isolates obtained from both invasive and non-invasive Streptococcus pyogenes infections in Hong Kong, between October 2005 and April 2008. METHOD Clinical data of invasive isolates were collected retrospectively. Altogether 281 isolates were emm sequence typed and(More)
symptom onset, increased during the symptomatic period (as shown by higher titers on day 10), peaked by day 30 (2 weeks after recovery), then declined slowly over several years. Zaire ebolavirus IgG remained detectable, often at high levels, >11 years after the infection. These long-lasting IgG antibody responses found in 20 survivors of 3 different Zaire(More)
