BACKGROUND The epidemiology of local viral etiologies is essential for the management of viral respiratory tract infections. Limited data are available in China to describe the epidemiology of viral respiratory infections, especially in small-medium cities and rural areas. OBJECTIVES To determine the viral etiology and seasonality of acute respiratory infections in hospitalized children, a 3-...

BACKGROUND In 2005 northern parts of Pakistan were hit by an earthquake of magnitude 7.6 on rector scale. Fatima Memorial Hospital established a Primary Health care centre in village of Jared in Kaghan valley. The objective of the study was to find the pattern of different diseases presetting to health centre. METHODS All cases between August 2006 and December 2008 were included from the dail...

cryptosporial and bacterial co-infection is reported in a budgerigar with clinical manifestations of septicemia and respiratory tract infection. microscopically large number of round to oval 2-5μm cryptosporidial organisms were found to be lodged on the parabronchial epithelial cells of the respiratory tract. the bacterial colonies were seen around the parabronchial spaces of the lung tissue. i...

Respiratory tract infections (RTIs) are inflammatory diseases caused by pathogenic microorganisms.1 In the early stage of infection, the pathogenic factors are usually viruses, and bacterial infections often occur secondary to viral infection.2,3 Respiratory viral infections continue to attack human populations, as in the severe acute respiratory syndrome (SARS) epidemic in Hong Kong in 1997 an...

Given that COVID-19 is a global public health problem and almost all countries in the world have been severely affected by pandemic, research being actively pursued to better understand effects of virus on human cells. However, it not clear what changes are observed cells main gate infection – mucosa mouth nose at different clinical forms periods disease. Understanding ultra-structural cell SAR...

INTRODUCTION The aetiology of lower respiratory tract infections in young children admitted to the paediatric intensive care unit (PICU) is often difficult to establish. However, most infections are believed to be caused by respiratory viruses. A diagnostic study was performed to compare conventional viral tests with the recently developed real-time PCR technique. METHOD Samples from children...

OBJECTIVE To evaluate retrospectively the relationship between meteorological factors in Shenmu County, Yulin City, Shaanxi Province, China and the incidence of lower respiratory tract infections in children. METHODS Meteorological data (air temperature, atmospheric pressure, rainfall, hours of sunlight, wind speed and relative humidity) for Shenmu County and medical data from hospitalized pa...

Bacterial and viral co-infections of the respiratory tract are life-threatening and present a global burden to the global community. Staphylococcus aureus, Streptococcus pneumoniae, and Streptococcus pyogenes are frequent colonizers of the upper respiratory tract. Imbalances through acquisition of seasonal viruses, e.g., Influenza A virus, can lead to bacterial dissemination to the lower respir...

This study was performed to investigate the etiologic agents, age distribution, clinical manifestations and seasonal occurrence of acute viral lower respiratory tract infections in children. We confirmed viral etiologies using nasopharyngeal aspirates in 237 patients of the ages of 15 years or younger who were hospitalized for acute lower respiratory tract infection (ALRI) from March 1996 to Fe...
