OBJECTIVE: In this study, the survival and recovery of Chlamydia pneumoniae (Cp) strains TW-183, AR-39, AR-388 and CWL-029 were measured after inoculation on glass, stainless steel, FormicaR laminate, paper, fabric and human skin. METHODS: Inoculum in throat washes from healthy volunteers was applied to each surface. Samples were taken immediately after inoculum application and at specified intervals thereafter to determine infectivity. RESULTS: Infectious Cp was recovered from glass for up to 4 h, from paper and fabric for up to 3 h, from FormicaR laminate for up to 2 h, from stainless steel for up to 60 min and from human skin for up to 30 min. Drying of the inoculated area had no significant effect on the recovery of infectious Cp. Further experiments demonstrated that infectious Cp could be transferred to hands by touching these contaminated surfaces and could be recovered from these hands for up to 3 min. Addition of albumin, surfactant or phosphatidylcholine had no significant effect on the survival of Cp. CONCLUSIONS: These results suggest that contact with contaminated surfaces may be a potential mode of transmission of Cp.

Correlation Between Inflammatory Markers and Pathogenic Bacteria in Children's Winter Respiratory Infections in Xinjiang.
Int J Gen Med
January 2025
Department of Respiratory and Critical Care Medical Department Infectious Diseases Ward, The Traditional Chinese Medicine Hospital Affiliated to Xinjiang Medical University, Urumqi, Xinjiang, People's Republic of China.
Background: This study examines the distribution characteristics of pathogenic bacteria in respiratory infections and their relationship with inflammatory markers to guide clinical drug use.
Methods: We selected 120 patients with lower respiratory tract infection in the electronic medical record system of Xinjiang Provincial People's Hospital from March 2019 to March 2023 for a case-control study. Using Indirect Immunofluorescence Antibody test(IFA), blood routine, C-reactive Protein (CRP), and High-sensitivity C-reactive Protein(hsCRP), we detected nine respiratory pathogens (Respiratory syncytial virus; Influenza A virus; Influenza B virus; Parainfluenza virus; Adenovirus; Mycoplasma pneumoniae; Chlamydia pneumoniae; Legionella pneumophila type 1; Rickettsia Q) in all patients and analyzed their distribution and correlation.

Background: Primary biliary cholangitis (PBC) is a cholestatic, autoimmune liver disease with the presence of characteristic autoantibodies. The aim of the work was to determine the level of antibodies directed against bacterial antigens: (anti-anti), (anti-), (anti- ) and () in sera of PBC patients. We also performed studies on the impact of the bacterial peptides on the specific antigen-antibody binding.

Background: To explore the effect of non-pharmacological interventions (NPIs) on respiratory pathogen profiles among hospitalized infants aged 0-3 months in Beijing during the coronavirus disease 2019 (COVID-19) pandemic.
Methods: Respiratory specimens were collected from 1,184 infants aged 0-3 months who were hospitalized for acute respiratory infection at the Children's Hospital affiliated with the Capital Institute of Pediatrics from January 2018 to December 2023. The data were divided into three groups-the pre-epidemic (January 2018 to December 2019), epidemic prevention and control (January 2020 to December 2022), and post-epidemic (January 2023 to December 2023) groups-based on the outbreak of COVID-19 and the implementation and termination of NPIs.
