Two species of entomogenous fungi were discovered infecting the invasive paper wasp during an ecological study on Farewell Spit, New Zealand. We sequenced two nuclear ribosomal RDNA genes, the internal transcribed spacer (ITS) and the small ribosomal subunit 18S, and one protein-coding gene, the translation elongation factor 1-alpha (). Combining sequence information with morphological examination, we identified these species as and . We estimated that these fungi produce infection in approximately 3.3% of colonies in our study population. In bioassays, we successfully infected individuals from healthy colonies with , with significant effects on adult mortality. This is the first record of both and from Polistine hosts in New Zealand, and the first investigation into disease causality by these pathogens in . Our findings may contribute to the future development of biological control agents for paper wasps in New Zealand and elsewhere around the world.

Background: Group B streptococcus (GBS) causes neonatal invasive disease, mainly sepsis and meningitis. Understanding the clinical characteristics, laboratory tests, and antibiotic resistance patterns of GBS invasive infections provides reliable epidemiological data for preventing and treating GBS infections.
Methods: Clinical characteristics and laboratory test results from 86 patients with neonatal invasive disease (45 cases of early-onset disease [EOD] and 41 cases of late-onset disease [LOD]) recruited from Fujian Maternity and Child Health Hospital between January 2012 and December 2021 were analyzed.

SUMMARY is a major human pathogen. It can cause many types of infections, in particular bacteremia, which frequently leads to infective endocarditis, osteomyelitis, sepsis, and other debilitating diseases. The development of secondary infections is based on the bacterium's ability to associate with endothelial cells lining blood vessels.

Unlabelled: Although fish possess an effective interferon (IFN) system to defend against viral infection, grass carp reovirus (GCRV) still causes epidemic hemorrhagic disease and tremendous economic loss in grass carp. Therefore, it is necessary to investigate the immune escape strategies employed by GCRV. In this study, we show that the structural protein VP4 of GCRV (encoded by the S6 segment) significantly restricts IFN expression by degrading stimulator of IFN genes (STING) through the autophagy-lysosome-dependent pathway.

Studying the molecular basis of intestinal infections caused by enteric pathogens at the tissue level is challenging, because most human intestinal infection models have limitations, and results obtained from animals may not reflect the human situation. Infections with Salmonella enterica serovar Typhimurium (STm) have different outcomes between organisms. 3D tissue modeling of primary human material provides alternatives to animal experimentation, but epithelial co-culture with immune cells remains difficult.

Due to its relative rarity, clinical data, pathological features, and molecular characteristics of ISMC are still under exploration. This study aims to retrospectively analyze the clinical data and pathological features of ISMC patients, summarizing the clinical and pathological morphological characteristics of ISMC.
