We describe three cases of acute uncomplicated bacterial pneumonia due to viridans streptococci in previously healthy adults, which were indistinguishable from those caused by other well-known respiratory pathogens. On arrival, all of these patients were treated with IV aqueous penicillin based on Gram stain of sputum which showed predominant Gram-positive cocci in pairs and chains. These speci...

Streptococcus pneumoniaeis the leading cause of community-acquired pneumonia. Levofloxacin is a fluoroquinolone used for treatment of severe community-acquired pneumonia. Here, we describe the draft genome sequences ofS. pneumoniaewith emerging resistance to levofloxacin, resulting in failure of treatment of pneumococcal pneumonia.

Legionellosis refers to the two clinical syndromes caused by Legionella : Pontiac fever, a benign febrile illness and Legionnaires'disease (or pneumonia). Clinically and radiologically, Legionnaires'disease presents itself as a « typical » pneumonia caused by Streptococcus pneumonia. Diagnosis is usually made by using urinary antigen testing. Culture and PCR are also helpful. Legionella is resi...

Streptococcus pneumoniae (pneumococcus) is a Gram-positive diplococcus responsible for a spectrum of clinical syndrome including non-invasive infections such as paranasal sinusitis, otitis media and lobar pneumonia as well as invasive diseases, such as bacteremic pneumonia and meningitis. Pneumococcus is the most common cause of community-acquired pneumonia (CAP) in both ambulatory and hospital...

Organizing pneumonia is a rare complication of influenza infection that has substantial morbidity. We report the first case of organizing pneumonia associated with influenza B and Streptococcus pneumoniae coinfection that had significant improvement with corticosteroid treatment. The clinical and radiological features of organizing pneumonia associated with this coinfection are similar to those...

BACKGROUND There are few data on paediatric community acquired pneumonia (PCAP) in the UK. AIMS To investigate the aetiology and most useful diagnostic tests for PCAP in the north east of England. METHODS A prospective study of hospital admissions with a diagnosis of PCAP. RESULTS A pathogen was isolated from 60% (81/136) of cases, and considered a definite or probable cause of their pneu...

OBJECTIVE Streptococcus pneumoniae is an important and common pathogen of acute pneumonia. The urinary pneumococcal antigen test has been increasingly used for the diagnosis of pneumococcal pneumonia, but there have been few studies on pneumococcal pneumonia after this test became prevalent. The present study was conducted to characterize the clinical features of pneumococcal pneumonia after th...

Objective: To analyze the causes of childhood pneumonia Streptococcus pneumoniae resistance and clinical characteristics, provide a basis for better timely therapy, medication to reduce blindness. Methods: MIC method in our hospital 114 under 2020 pediatric pneumococcal respiratory infection children with lower tract specimens were isolated antimicrobial susceptibility testing, analyzed retrosp...
