The characteristics of nine children with community acquired pneumonia with evidence of Streptococcus pneumoniae and Mycoplasma pneumoniae coinfection are described.

1. Pulmonary consolidation may be produced in normal mice by the inhalation of Friedländer's bacillus or Streptococcus haemolylicus. 2. The initial lesion is in both instances interstitial in character and the spread is by way of the interstitial tissue, though the ultimate consolidation may come to resemble in the gross a lobar pneumonia. 3. The lesions grossly and microscopically may be disti...

Streptococcus pneumoniae is a pathogen known to cause pneumonia, sinusitis, meningitis, and otitis media, but is overlooked as a pathogen causing gastrointestinal illness. We report four cases of Streptococcus pneumoniae causing intra-abdominal and pelvic infection. Streptococcus pneumoniae should be considered in the setting of intra-abdominal infection, especially in patients with risk factor...

Hypersensitivity vasculitis (HSV) has been used to describe several forms of vasculitis of small blood vessels, including Henoch-Schönlein purpura (HSP), mixed cryoglobulinemia, and allergic vasculitis, etc. HSP is a disease occasionally seen in childhood, and is characterized by dermatological and abdominal symptoms. Here, we report a rare case of HSV which showed a clinical course similar to ...

Group B Streptococcus commonly colonises healthy adults without symptoms, yet under certain circumstances displays the ability to invade host tissues, evade immune detection and cause serious invasive disease. Consequently, Group B Streptococcus remains a leading cause of neonatal pneumonia, sepsis and meningitis. Here we review recent information on the bacterial factors and mechanisms that di...

This cross sectional study was conducted to identify the common bacterial causes of community acquired pneumonia (CAP) from sputum and blood by culture and polymerase chain reaction (PCR) and to evaluate the effectiveness of these tests. A total of 105 sputum and blood samples were collected from patients with pneumonia on clinical suspicion. Common causative bacterial agents of pneumonia were ...

Streptococcus pneumoniae is the most common bacterial cause of community acquired pneumonia. The current trend in Streptococcus pneumoniae infections has been the rise of multi-drug resistance in the last two decades. We present the case of a pair of 16-month old African-American fraternal twins who presented to the emergency room on the same day for symptoms consistent with pneumonia. Upon fur...

We report the use of FilmArray Blood Culture Identification (BCID) multiplex PCR system for pathogen detection from a child with septic arthritis that Streptococcus pyogenes was identified directly from synovial fluid and a child with complicated pneumonia with pleural effusion that Streptococcus pneumoniae was identified from pleural fluid.

Enzootic pneumonia (EP) is characterized by high morbidity and low mortality, and although pigs of all ages are susceptible to Mycoplasma hyopneumoniae infection, a variety of other respiratory pathogens plays an important role in the development of Porcine Respiratory Disease Complex (PRDC) like Actinobacillus pleuropneumoniae, Bordetella bronchiseptica, Pasteurella multocida, Streptococcus su...

Spherical pneumonia, which is seen more frequently in children than in adults, is usually manifested as a solitary nodule. We report the case of a middle-aged man with small spherical pneumonia, with multiple distribution in the right lung, caused by Streptococcus pneumoniae. This type of pneumonia is very unusual and should be included in the differential diagnosis of multiple nodular densitie...
