BACKGROUND Many suburban sexual health clinics exist in Australasia. However, sexual health research has hitherto been restricted to populations from major metropolitan centres. OBJECTIVE To describe the demographic, sexual characteristics and presenting diagnoses of 6521 new patients attending a sexual health clinic in the western suburbs of Sydney (New South Wales). DISCUSSION Patients or...

The sera of patients with traveler's diarrhea were assayed for rotavirus-specific immunoglobulins in enzyme-linked immunosorbent and micro-neutralization assays. The antigenically related simian rotavirus SA-11 was used in both assays. Although similar titers of rotavirus-specific binding immunoglobulin G and A were observed in the sera of both symptomatic and asymptomatic subjects, clinical il...

A total of 12 horses of different breeds and ages were infected with West Nile virus (WNV) via the bites of infected Aedes albopictus mosquitoes. Half the horses were infected with a viral isolate from the brain of a horse (BC787), and half were infected with an isolate from crow brain (NY99-6625); both were NY99 isolates. Postinfection, uninfected female Ae. albopictus fed on eight of the infe...

OBJECTIVES To determine the utility of urine-based ligase chain reaction assays for Neisseria gonorrhoeae and Chlamydia trachomatis in (1) the acceptability of such testing to adolescent detainees, (2) the potential use of these tests for identifying asymptomatic infections, and (3) the effectiveness of this approach for ensuring treatment of infected adolescents. DESIGN Cross-sectional scree...

OBJECTIVES HIV 'treatment as prevention' (TasP) describes early treatment of HIV-infected patients intended to reduce viral load and transmission. Crucial assumptions for estimating TasP's effectiveness are the underlying estimates of transmission risk. We aimed to determine transmission risk during primary infection, and describe the relation of HIV transmission risk to viral load. DESIGN A ...

To determine the duration and complexity of naturally acquired Plasmodium falciparum infections in small children, a longitudinal cohort study of 143 newborns was conducted in coastal Ghana. On average, children experienced 2 episodes of infection in their first 2 years of life, the median duration of an asymptomatic infection was <4 weeks, and estimates of the mean number of parasite genotypes...

Cryptococcus gattii, formerly known as Cryptococcus neoformans var gattii, is an encapsulated yeast that causes disease in both immunocompetent and immunosuppressed individuals. The organism enters via the respiratory tract and causes a spectrum of illness ranging from asymptomatic infection to severe illness, including pneumonia and disseminated infection involving multiple sites, including th...

BACKGROUND Despite large-scale vaccination programmes, pertussis has remained endemic in all European countries and has been on the rise in many countries in the last decade. One of the reasons that have been discussed for the failure of vaccination to eliminate the disease is continued circulation of the pathogen Bordetella pertussis by mostly asymptomatic and mild infections in adolescents an...

It is now widely recognized not only that urinary infection in childhood is a common and recurrent condition, but also that symptomatic improvement of the acute episode, whether spontaneous or after a short course of chemotherapy, may be followed by persistent asymptomatic infection (Kass, 1956; Kunin et al., 1964; Dunn et al., 1964). It is also accepted that infection of the urinary tract in c...

background: diabetic patients are more susceptible to urinary tract infections (uti) than non-diabetics .this study was carried out to determine the prevalence and risk factors of urinary tract infections in type 2 diabetic women in tehran. methods: this cross sectional study was designed to examine 511 non-pregnant type 2 diabetic women using consecutive sampling during september and march 200...
