Japanese encephalitis virus (JEV) infection can cause brain tissue lesions characterized by neuronal death, and apoptosis is involved in JEV-induced neuronopathy. In the present study, mouse microglia were infected with JEV, and pyknosis with dark-staining nuclei of infected cells was detected using Hoechst 33342 staining. TUNEL staining showed that JEV infection promoted the apoptosis of BV2 cells, and the apoptosis rate was significantly increased at 24-60 hours postinfection (hpi) (P < 0.01) and was the highest at 36 h (P < 0...

REVIEW
Robério Amorim de Almeida Pondé
Vertical hepatitis B virus (HBV) transmission is defined as transmission that occurs during pregnancy or postpartum from an HBV-infected mother to her fetus or child. It is an efficient route for the spread of HBV and is responsible for most of the cases of chronic HBV infection in adults. During pregnancy, vertical transmission can occur in the intrauterine phase, by placental infection via peripheral blood mononuclear cells, by placental leakage, or through female germ cells.The detection of HBV DNA in semen and spermatids from HBV-infected men has provided strong evidence that the male genital tract may act as a reservoir of the virus in HBV-infected men, supporting the possibility that vertical HBV transmission from an HBV-infected father to his child may also occur via the germ line at the time of fertilization, as occurs in HBV transmission from mother to child...

Clostridium perfringens is a constituent of the normal gut microbiome in pigs; however, it can potentially cause pre- and post-weaning diarrhea. Nevertheless, the importance of this bacterium as a primary pathogen of diarrhea in piglets needs to be better understood, and the epidemiology of C. perfringens in Korean pig populations is unknown. To study the prevalence and typing of C. perfringens, 203 fecal samples were collected from diarrheal piglets on 61 swine farms during 2021-2022 and examined for the presence of C...

A bovine rotavirus (BRV) isolate from Kirsehir was isolated from feces of a neonatal calf with diarrhea, identified, and sequenced by shotgun sequencing. Its genotype constellation is G10-P[5]-I2-R2-C2-M2-A3-N2-T6-E2-H3. The structural genes and the non-structural genes NSP1, NSP3, and NSP4 of the Kirsehir isolate were similar in sequence to those of BRVs identified in Turkey. However, VP2, NSP2, NSP4, and NSP5/6 showed similarity to those of rotaviruses from different animal hosts. These findings not only expand our current understanding of the diversity of rotaviruses but also contribute to our understanding of the evolution of rotaviruses at both the national and global levels and reinforce the significance of conducting further research on rotaviruses in Turkey...

The currently dominant Omicron variant of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has swiftly diverged into clades. To predict the probable impact of these clades, the consensus insertions/deletions (indels) and amino acid substitutions of the whole genome of clades were compared with the original SARS-CoV-2 strain. The evolutionary history of representatives of clades and lineages was inferred using the maximum-likelihood method and tested using the bootstrap method. The indels and polymorphic amino acids were found to be either clade-specific or shared among clades...

New antiviral agents for the treatment of herpes simplex virus type 1 (HSV-1) infection, which causes a highly prevalent and incurable disease, are needed. Here, we report for the first time the in vitro anti-HSV-1 activity of two dibenzylideneketone compounds: DBK1 and DBK2. DBK1 demonstrated virucidal activity, and high-resolution scanning electron microscopy showed that it caused morphological changes in the HSV-1 envelope. DBK2 was able to reduce HSV-1 plaque size in vitro. The DBKs are promising anti-HSV-1 candidates, as they exhibit low toxicity and exert an antiviral effect by acting at the early stages of HSV-1-host cell interaction...
