Objective: To investigate the distribution of HPV 16 variants in Han women patients without Cervical intraepithelial neoplasia in the diagnosis and treatment center for cervical disease, department of Obstetrics and Gynecology in China-Japan friendship hospital with HPV 16 E5 sequence phylogenetic analysis.
Methods: PCR amplification of HPV 16 E5 sequences and sequenced. The association between variations types and different cervical lesions was analyzed.
Results: In this research, We first found that variant classification based on HPV 16 E5 DNA sequence (236 bp) alone had high rate of accuracy. In addition, for the first time, our research revealed that single-4075T can distinguished the As variant from all other variants.
Conclusion: If E5 sequence was used for phylogenetic analysis, it will greatly reduce the experimental costs and improve efficiency and cost-effectiveness. For the first time, our research revealed that single 4075T can distinguished the As variant from all other variants.

The Mycobacterium avium complex (MAC) is a group of closely related nontuberculous mycobacteria that can cause various diseases in humans. In this study, genome sequencing, comprehensive genomic analysis, and antimicrobial susceptibility testing of 66 MAC clinical isolates from King Chulalongkorn Memorial Hospital, Bangkok, Thailand were carried out. Whole-genome average nucleotide identity (ANI) revealed the MAC species distribution, comprising 54 (81.

The relative contributions of mutation rate variation, selection, and recombination in shaping genomic variation in bacterial populations remain poorly understood. Here we analyze 3318 Yersinia pestis genomes, spanning nearly a century and including 2336 newly sequenced strains, to shed light on the patterns of genetic diversity and variation distribution at the population level. We identify 45 genomic regions ("hot regions", HRs) that, although comprising a minor fraction of the genome, are hotbeds of genetic variation.

Black-goggled tanagers Trichothraupis melanops (Vieillot, 1818) are passerine birds commonly observed in the Brazilian Atlantic Forest, Argentina and Paraguay. Tanagers are among the passerines with the highest prevalence and density of coccidian parasites, mainly due to their frugivorous feeding habits that favor fecal-oral transmission. In this context, the current study identifies a new species of Isospora Schneider, 1881 parasitizing black-goggled tanagers captured in the Itatiaia National Park, a protected area with a high degree of vulnerability in Southeastern Brazil.

Uridine diphosphate-glycosyltransferases (UGTs) are responsible for glycosylation by combining various small lipophilic molecules with sugars to produce water-soluble glycosides, which are crucial for the metabolism of plant secondary metabolites and detoxification in insects. This study presents a genome-wide analysis of the UGT gene family in the brown planthopper, Nilaparvata lugens, a destructive insect pest of rice in Asia. Based on the similarity to UGT homologs from other organisms, 20 putative NlUGT genes were identified in N.
