Unlabelled: Pulmonary abscess is an uncommon complication of pneumonia in children. Pyogenes, in particular Staphylococcus aureus or Streptococcus pneumoniae are the principal responsible bacteria. Mycoplasma pneumoniae is rarely the cause.
Case Report: A 14-year-old child was hospitalized with right thoracic pain. The patient was non-febrile and had a recent history of moderate infection. He was receiving antibiotic (macrolide) and non-steroidal anti-inflammatory therapy. CT scan confirmed a mid-lobe abscess in the right lung. Interruption of therapy resulted in fever and increase in C-reactive level with hyperleucocytosis, suggesting that the abscess was caused by a bacterial infection. The child's general condition and the radiographic picture improved with combined antibiotic therapy with amoxycillin and clavulanic acid, aminoglycosides and macrolides. The suspected diagnostic of M. pneumoniae was confirmed by increased IgM antibodies for M. pneumoniae. Recovery was complete two months later without sequelae.
Comment: Pulmonary abscess is a rare complication of M. pneumoniae infection in children. This complication should be considered when the general condition does not improve despite appropriate early treatment of a pneumonia, as in the case of our patient.

Preterm infants are at high risk of developing respiratory distress syndrome (RDS). Mutations in the genes encoding for surfactant proteins B and C or the ATP-binding cassette transporter A3 (ABCA3) are rare but known to be associated with severe RDS and interstitial lung diseases. The exact prevalence of these mutations in the general population is difficult to determine, as they are usually studied in connection with clinical symptoms.

Background: Avian mycoplasmas are small bacteria associated with several pathogenic conditions in many wild and poultry bird species. Extensive genomic data are available for many avian mycoplasmas, yet no comparative studies focusing on this group of mycoplasmas have been undertaken so far.
Results: Here, based on the comparison of forty avian mycoplasma genomes belonging to ten different species, we provide insightful information on the phylogeny, pan/core genome, energetic metabolism, and virulence of these avian pathogens.

Background: Severe fever with thrombocytopenia syndrome (SFTS) is an emerging infectious disease caused by Dabie bandavirus (DBV). We report a case of DBV and Mycoplasma pneumoniae (MP) co-infection.
Case Presentation: Here we reported a 57-year-old healthy male who was admitted with the presentations of fever, cough, hemoptysis, and hypotension.
Epidemiological Characteristics of Pathogens in Bronchoalveolar Lavage Fluid in Children With Lower Respiratory Tract Infections: A Retrospective Analysis.

Department of Pediatrics, Fu Yang People's Hospital, Fuyang, China.
Background: The COVID-19 pandemic has significantly altered the etiological spectrum and epidemiological characteristics of pediatric respiratory diseases, and a profound understanding of these changes is crucial for guiding clinical treatment. The purpose of this study is to analyze the etiological patterns and epidemiological features of pathogens in bronchoalveolar lavage fluid (BALF) from children with pediatric lower respiratory tract infections (LRTIs) after the COVID-19 pandemic, with the aim of providing effective therapeutic evidence for clinical practice.
Methods: This study enrolled pediatric patients diagnosed with LRTIs who were treated and underwent BALF pathogen detection at our hospital from June 1, 2023, to June 1, 2024.
