This report describes 28 genome sequences from a new clade within subtype 1 of , formerly known as porcine reproductive and respiratory syndrome virus 1. All share a potential recombinant pattern, with a highly pathogenic Italian strain as the putative major parental sequence and three other possible parents.

View Article and Find Full Text PDFAvian influenza is not a new disease, but the emergence of high pathogenicity avian influenza (HPAI) viruses of the A/Goose/Guangdong/1/96 lineage (Gs/GD) has necessitated fundamental changes to prevention and control strategies for this disease. No longer just an avian disease, avian influenza is capable of causing severe disease in humans and is considered a potential human pandemic threat requiring One Health approaches. In addition, Gs/GD HPAI viruses have developed the capacity to be carried across and between continents by migratory birds.

Introduction: In low-and-middle-income-countries (LMIC), viral suppression is defined as plasma viral load (PVL) below 1000 copies/mL (low-level viremia [LLV]) and threshold for HIV drug resistance (HIVDR) testing. However, there is evidence that drug resistance mutations (DRMs) may emerge at LLV, thus compromising antiretroviral treatment (ART) response We evaluated sequencing success rates (SSR) at LLV, described HIVDR profiles and adequacy with potential efficacy of tenofovir-lamivudine-dolutegravir (TLD).
Methods: A cross-sectional study was conducted among individuals with LLV at the Chantal BIYA International Reference Centre, Yaoundé, Cameroon from January 2020 through August 2021.

We constructed a simple genotyping method combining multiplex allele-specific PCR and DNA chromatography for Salmonella enterica subsp. enterica serovar Typhimurium and its monophasic variant. The developed method can be used to estimate the genetic background of isolates, and it facilitates easy identification of several epidemic clades among these serotypes.

The global spread of the highly pathogenic avian influenza (HPAI) A(H5N1) virus poses a serious pandemic threat, necessitating the swift development of effective vaccines. The success of messenger RNA (mRNA) vaccine technology in the COVID-19 pandemic, marked by its rapid development and scalability, demonstrates its potential for addressing other infectious threats, such as HPAI A(H5N1). We therefore evaluated mRNA vaccine candidates targeting panzootic influenza A(H5) clade 2.
