Of the patients with concurrent infection, 44 were infected with more than one organism. influenzae, 37 with Staphylococcus aureus, 25 with meticillin-resistant Staphylococcus aureus (MRSA), 20 with Pseudomonas aeruginosa and some with other pathogens, who were diagnosed with concurrent infectious diseases by serological tests and clinical findings. catarrhalis pulmonary infection who had undergone pulmonary thin-section CT scans between January 2004 and March 2009 at four institutions.

We retrospectively identified 292 patients with acute M. Our institutional review board approved this retrospective study and waived informed consent.

Therefore, this study aimed to assess the clinical and pulmonary thin-section CT findings in acute M. catarrhalis pulmonary infection have been published. However, to the best of our knowledge, no other English-language studies of pulmonary CT findings in patients with acute M. catarrhalis in a haematopoietic stem cell transplant patient. The main aetiology for the majority of episodes is infection.Īl-Anazi et al reported a CT image of pneumonia associated with M. Acute exacerbation is a frequent event during the prolonged chronic course of COPD, which entails significant morbidity and mortality. catarrhalis infection has received increasing attention because it is an important factor in the acute exacerbation of chronic obstructive pulmonary disease (COPD). catarrhalis involve the respiratory tract and outbreaks have been reported in respiratory units and paediatric intensive care units. catarrhalis infection were infected in a hospital and that the infection was associated with the proximity of the patient to other patients. McLeod et al reported that 43 of 81 patients (53%) with M. catarrhalis was suggested to occur within the hospital environment. On the basis of epidemiological evidence, the spread of M. catarrhalis has also gained attention as a nosocomial respiratory pathogen and as a community-acquired pathogen. catarrhalis was identified in 13.5% of bacterial isolates. In the Alexander project in Europe and the US between 19, M. catarrhalis is considered to be the third most common and most important cause of bronchopulmonary infections after Streptococcus pneumoniae and Haemophilus influenzae. The pathogen, also known as Micrococcus catarrhalis, Neisseria catarrhalis and Brahamella catarrhalis, is a clinically important pathogen and is a common cause of respiratory infections, particularly otitis media in children and lower respiratory tract infection in elderly patients. Moraxella catarrhalis is a Gram-negative, aerobic, oxidase-positive diplococcus that was first described in 1896.
