This systematic review and meta-analysis evaluate human papillomavirus (HPV) prevalence, genotype distribution, and associations with cervicovaginal microbiota and cytokine profiles among South African women, where cervical cancer ranks as the second most common cancer. PubMed, SCOPUS, and Web of Science were searched for studies on HPV infection up to 21 September 2024. The pooled prevalence was estimated using a random-effects model, with subgroup analyses by province, sample type, and HIV status.

Background/objective: This study aimed to investigate the efficacy of oral probiotic supplementation in preventing vulvovaginal infections (VVIs) in pregnant women, specifically focusing on abnormal vaginal flora (AVF), bacterial vaginosis (BV), and vulvovaginal candidiasis (VVC).
Methods: A multicenter-prospective-randomized, double-blind, placebo-controlled trial was conducted during 2016-2019. Women with normal vaginal flora (Nugent score < 4 and no candida) were divided into a research group, receiving 2 capsules/day of oral probiotic formula containing , , , , , and , or a control group, receiving a placebo until delivery.

Human papillomaviruses (HPVs) are responsible for the majority of sexually transmitted infections (STIs), some of which are oncogenic and can cause oropharyngeal or genital cancers. The HPV prevalence at the genital level varies according to the population studied but is higher in the seminal fluid of men suffering from idiopathic infertility than in the general population. The involvement of HPV in male infertility is supported by several studies suggesting that this virus can affect sperm quality by altering sperm DNA integrity, motility, number, viability, and morphology, and by inducing the production of anti-sperm antibodies (ASAs).

is a blood-sucking parasite that causes heavy infestations on cattle and is a vector for severe tick-borne diseases, such as anaplasmosis and babesiosis, and poses a significant threat to the cattle industry. Cattle ticks show increasing acaricide resistance, which creates an additional problem concerning the inefficient chemical control of tick populations in cattle-grazing areas, necessitating the exploration of alternative tick biocontrol methods. Our study aimed to demonstrate the acaropathogenic efficacy of two bacterial species during experimental infections on .

Pierid species of the group are among the largest Sino-Himalayan members of genus , with four conventionally recognised species, namely , , , and . Recent publications indicated that some of these species may contain more than one species despite their similar morphological characters. The present research analysed this group of butterflies using mitogenomic data, and proved that , , , and should be recognised as distinct species, while , and should be subspecies of .
