SETTING An urban sexual health centre. PARTICIPANTS 3973 women aged ≥ 16 years requesting testing for sexually transmitted infections. INTERVENTIONS Participants took a vulvovaginal swab before routine examination,...
BACKGROUND Indigenous Australian children living in remote communities experience high rates of acute otitis media with tympanic membrane perforation (AOMwiP). Otitis media in this population is associated with dense nasopharyngeal colonization of three primary otopathogens; Haemophilus influenzae, Streptococcus pneumoniae and Moraxella catarrhalis. Little is known about the relative abundance ...
The recovery of upper respiratory tract bacteria on laboratory media from a variety of swabs and swab-transport media kits was examined. Organisms studied included strains of Streptococcus pyogenes, Streptococcus pneumoniae, Staphylococcus aureus, Neisseria meningitidis and Haemophilus influenzae. Although a wide range of results was obtained with regard to variables such as the type of swab or...
This survey study was undertaken to find out the prevalence and distribution of fungi occupying residential surfaces in Azadi Teaching Hospital Hevi Paediatric Duhok province, Iraq. Three hundred samples were collected from randomly selected areas laboratories, wards, consultation rooms, operating theatres hospital kitchen by swabs. These cultured on two selective fungal media (PDA SDA) also ai...
Some microfungi are known to be opportunistic human pathogens, and there is a body of scientific opinion that one of their routes of infection may be water aerosols. Others have been implicated as causative agents of odours and off-tastes in drinking water. This study was undertaken to investigate three potential sources of microfungi in a treated, oligotrophic municipal water supply system in ...
This paper analyses the results of diagnostic swabs taken from children seen at a pertussis contact clinic between December, 1950, and April, 1952. Two new diagnostic techniques entailing contaminating swabs by cough, which were developed during this period, yielded a high percentage of positive cultures. A preliminary communication on one of these new techniques was published when the initial ...
Detection of influenza virus in oropharyngeal swabs collected during wild bird surveillance is assumed to represent respiratory infection, although intestine is the main site of infection. We tested this assumption by histological examination of the respiratory tract of wild Mallards with virus-positive oropharyngeal swabs. Thirty-two of 125 Mallards tested had viral-RNA positive oropharyngeal ...
Salmonella enterica serotype 4,[5],12:i:- (STM) has become an increasing problem for food safety and been often detected in pork products. For this study, weanling pigs were exposed to STM-contaminated feed, water, or air determine possible STM transmission routes. An uninoculated control group of was included. The monitored daily feces rectal nasal swabs. colonization most prevalent tissues fr...
Background & Objective: A simple approach to prevent close contact in healthcare settings during the COVID-19 outbreak is to train patients to collect their own nasopharyngeal and oropharyngeal swabs and deliver them to medical laboratories to have them processed. The aim of our study was to c...
