OBJECTIVES Swine have been regarded as intermediate hosts in the spread of influenza from birds to humans but studies of the sialylated glycans that comprise their respiratory tract have not been extensively studied in the past. This study analyzed the sialylated N-glycan and O-glycan profile of swine trachea and lung and correlated this with ex-vivo infection of swine explants with avian influ...

INTRODUCTION Inappropriate use of antibiotics leads to increased levels of bacterial resistance making it difficult to treat upper respiratory tract infections. The appropriate use of these drugs has a fundamental role in controlling resistance and in success of treatment of childhood infections. Therefore, the aim of this study was to assess the prescription and use of antibiotics for Brazilia...

BACKGROUND Maternal obesity is increasingly prevalent in many westernized countries. Many studies report associations between maternal obesity and childhood wheeze or asthma but few have considered maternal obesity in relation to respiratory infections or symptoms other than wheeze during infancy. This study assesses the relationship between maternal BMI and reported wheeze, cough and respirato...

background nosocomial infections are generally occurring 72 hours after admittance and are not present or incubating prior to admittance. the most common nosocomial infection is urinary tract infection (uti). scanty data are available regarding the nosocomial infections in iranian teaching hospitals. the aim of the present study was to determine the frequency of symptomatic nosocomial uti, iden...

human coronaviruses–229E and -OC43 and severe acute respiratory syndrome–CoV were able to survive in suspension at room temperature for several days (8,9). Moreover, severe acute respiratory syndrome–CoV was completely inactivated after heat treatment at 60°C for 30 min (9). Human-to-human transmission of MERS-CoV is inefficient, and the transmission route has not yet been revealed. The predomi...

Lower respiratory tract infection (LRTI) is the leading global cause of death in children between 1 month and 5 years of age [1-4]. Clinical characteristics of RSV infection include upper respiratory infection with rhinorrhea and nasal congestion lasting between 7 and 12 days. Re-infection rates vary between 6% and 83% each year, showing that initial infection does not confer immunity to succee...

ABSTRACT             Background and objectives: Coronaviruses are the main causes of respiratory tract infections in humans. They are also the second leading cause of common cold after rhinoviruses, and can lead to otitis media and asthma. The aim of this study was to investigate the molecular detection of coronaviruses in clinical samples of patients with flu-like symptoms.             Metho...

Respiratory infections are the greatest single contributor to the overall burden of disease worldwide [1]. Polymicrobial infections are becoming increasingly recognized in terms of both prevalence and their effect on disease severity, causing many common diseases such as oral infections, otitis media, chronic wound infections, and implanted medical device infections, as well as chronic pulmonar...
