Serotype distribution, antibiotic resistance, multilocus sequence typing, and virulence factors of invasive and non-invasive Streptococcus pneumoniae in Northeast China from 2000 to 2021.

Streptococcus pneumoniae infection is a major public health concern with high morbidity and mortality rates. This study aimed to evaluate the serotype distribution, antimicrobial resistance changes, clonal composition, and virulence factors of S. pneumoniae isolates causing pneumococcal disease in northeast China from 2000 to 2021.

Prevalence of microorganisms co-infections in human papillomaviruses infected women in Northern China.

Purpose: Due to scarce data on the prevalence of genital microorganism infections among individuals with human papillomavirus (HPV) infections, the present study aimed to evaluate microorganism co-infections and associated risk factors in HPV-infected women in Northern China.

Methods: Cervical samples of 4290 enrolled female patients were collected to detect HPV, bacterial and yeast infections in gynecologic outpatients. Serum samples collected were analyzed for the presence of serological markers for human immunodeficiency virus (HIV), hepatitis B (HBV) and hepatitis C (HCV) and Treponema pallidum infections.

[High-throughput genotyping multiplex ligation-dependent probe amplification for assisting diagnosis in a case of anti-Di(a)-induced severe hemolytic disease of the newborn].

Objective: To report a rare case of hemolytic disease of the newborn (HDN) with kernicterus caused by anti-Di(a) diagnosed using high-throughput genotyping multiplex ligation-dependent probe amplification (MLPA).

Methods: Conventional serological methods were used to detect the antibodies related with HDN. The genotypes of more than 40 red blood cell antigens for the newborn and her parents were obtained using the high-throughput MLPA assay.

[Analysis on the characteristics of blood serum Ab-IgG detective result of severe acute respiratory syndrome patients in Guangzhou, China].

Objective: To probe blood serum Ab-IgG characteristics of severe acute respiratory syndrome (SARS) patients in Guangzhou and investigate the related factors.

Methods: The serum of such population diagnosed as SARS convalescent patients, non-SARS patients, family consanguineous contraction persons, wild animal and vegetable salesman and community common people was collected. The lab detective method of ELISA was adopted for these serum samples.

[Discoveries of avian influenza A(H9N2) virus in chickens and men infected by H9N2 virus in Guangzhou area].

Objective: To understand the epidemic status of avian influenza A virus in chickens and men in Guangzhou area and to prevent men suffering from avian influenza A (H5N1) virus.

Methods: Etiologic and serological surveys were conducted in chickens and men who were working in the poultry farms and slaughter house. Viruses were isolated with both MDCK cells and embryonated chicken eggs.
