Two clinical strains, NF 296 and NF 931, present in our collection, were identified biochemically as members of CDC group II-i. Determination of the 16S rRNA gene sequence revealed highest similarity with strains of Sphingobacterium mizutaii. Because these strains produced indole, whereas S. mizutaii has been described as indole-negative, we also investigated the type strain and a reference strain of S. mizutaii, LMG 8340(T) (=CCUG 15907(T)) and LMG 8341 (=CCUG 15908), and found both strains also to be positive for indole production. These data warrant inclusion of some of the CDC group II-i strains into S. mizutaii and emended descriptions of Sphingobacterium mizutaii as indole-production-positive and of the genus Sphingobacterium as variable for indole production.

The southern house mosquito Culex quinquefasciatus in Abu Dhabi, UAE, is developing resistance to deltamethrin insecticide.

Culex quinquefasciatus is a widely spread mosquito species that poses a significant public health threat in many countries. This insect vector is present in the United Arab Emirates (UAE), yet no studies have been conducted on its resistance to any insecticide group. Research shows that controlling mosquitoes is crucial to eliminating mosquito-borne diseases, but when these vectors develop insecticide resistance, the situation can escalate dangerously out of control.

This study examines the impact of HIV post-exposure prophylaxis (PEP) on sexual behavior changes in men who have sex with men (MSM), aiming to assess a comprehensive HIV prevention strategy integrating biomedical and behavioral interventions to maximize PEP service effectiveness. From a Guangzhou MSM cohort, participants without prior PEP experience were included. The exposed group received PEP services during follow-up (June 2019-April 2022), while controls did not.

Purpose: Intrahepatic cholangiocarcinoma (ICC) arises from the epithelial cells of the bile ducts present inside the liver parenchyma and is associated with an overall poor prognosis due to advanced disease stage at the time of diagnosis. We used the Centers for Disease Control and Prevention Wide-Ranging Online Data for Epidemiologic Research (CDC WONDER) database to determine ICC-related mortality patterns in the United States from 1999 till 2020.
Methods: Age-adjusted mortality rates (AAMR) and crude mortality rates (CMR) were extracted from the CDC WONDER database.

Introduction: The establishment of a high-throughput quantification approach for waterborne pathogenic protozoa and helminths is crucial for rapid screening and health risk assessment.
Methods: We developed a high-throughput quantitative polymerase chain reaction (HT-qPCR) assay targeting 19 waterborne protozoa and 3 waterborne helminths and validated its sensitivity, specificity, and repeatability. The assay was then applied to test various environmental media samples.
The generation time, representing the interval between infections in primary and secondary cases, is essential for understanding and predicting the transmission dynamics of seasonal influenza, including the real-time effective reproduction number (Rt). However, comprehensive generation time estimates for seasonal influenza, especially since the 2009 influenza pandemic, are lacking. We estimated the generation time utilizing data from a 7-site case-ascertained household study in the United States over two influenza seasons, 2021/2022 and 2022/2023.
