Aspergillus fumigatus frequently colonizes the airways of patients with cystic fibrosis (CF) and may cause various severe infections, such as bronchitis. Serological data, sputum dependent markers and longitudinal data of treated cases of Aspergillus bronchitis were evaluated for further description of this infection. This study, which comprises three substudies, aimed to analyze epidemiological data of Aspergillus in CF and the entity of Aspergillus bronchitis. In a first step, data of the German Cystic Fibrosis Registry were used to evaluate the frequency of Aspergillus colonization in patients with CF (n = 2599)...

Urinary antigen test is frequently used as a routine laboratory test for early diagnosis of Legionella infection, which is especially suitable for ordinary Legionella pneumophila serogroup 1, but not for other types of Legionella. We report a case of severe pneumonia caused by Legionella longbeachae, where a method of loop-mediated isothermal amplification (LAMP) assay contributed an important role for the early detection. This case involved an 83-year-old man who developed fever, dyspnea, and productive cough...

Background. In pharmacokinetic/pharmacodynamics models of pulmonary Mycobacterium abscessus complex, the recommended macrolide-containing combination therapy has poor kill rates. However, clinical outcomes are unknown.Methods We searched the literature for studies published between 1990-2017 that reported microbial outcomes in patients treated for pulmonary M. abscessus disease. Good outcome was defined as sustained sputum culture conversion (SSCC) without relapse. Random effects models were used to pool studies and estimate proportions of patients with good outcomes...

Middle East respiratory syndrome (MERS) is an emerging zoonotic viral respiratory disease that was first identified in Saudi Arabia in 2012. In 2015, the largest MERS outbreak outside of the Middle East region occurred in the Republic of Korea. The rapid nosocomial transmission of MERS-coronavirus (MERS-CoV) in Korean healthcare settings highlighted the importance and urgent need for a rapid and reliable on-site diagnostic assay to implement effective control and preventive measures. Here, we describe the evaluation and validation of two newly developed reverse transcription-insulated isothermal PCR (RT-iiPCR) methods targeting the ORF1a and upE genes of MERS-CoV...

New non-sputum biomarker tests for active tuberculosis (TB) diagnostics are of highest priority for global TB control. We performed in-depth proteomic analysis using the 4000-plex SOMAscan assay on 1470 serum samples from seven TB-endemic countries. All samples were from patients with symptoms and signs suggestive of active pulmonary TB that were systematically confirmed or ruled-out for TB by culture and clinical follow-up. HIV-coinfection was present in 34%and 22% were sputum smear-negative. Serum protein biomarkers were identified by stability selection using L1-regularized logistic regression and by Kolmogorov-Smirnov (KS) statistics...
