Geographical differences in the prevalence of Helicobacter pylori genes and their association with disease severity have been identified. This study analyzes the prevalences of the cagA gene and alleles of the vacA gene in H. pylori-associated gastroduodenal diseases in isolates from Recife, PE, Brazil. Gastric biopsy of 61 H. pylori-positive patients were submitted to DNA extraction and gene a...

BACKGROUND The vacuolating cytotoxin and the cytotoxinassociated protein, encoded by vacA and cagA, respectively, are important virulence determinants of Helicobacter pylori. OBJECTIVE The aim of this study was to perform vacA genotyping and evaluate its association with cagA genotype and clinical outcome. METHODS One hundred and twenty H. pylori strains were isolated from dyspeptic patient...

The urgent need for effective, safe and equitably accessible vaccines to tackle the ongoing spread of COVID-19 led researchers generate vaccine candidates targeting varieties immunogens SARS-CoV-2. Because its crucial role in mediating binding entry host cell proven safety profile, subunit 1 (S1) spike protein represents an attractive immunogen development. Here, we developed assessed immunogen...

Twenty-two phages that infect Stenotrophomonas species were isolated through sewage enrichment and prophage induction. Of them, S1, S3, and S4 were selected due to their wide host ranges compared to those of the other phages. S1 and S4 are temperate siphoviruses, while S3 is a virulent myovirus. The genomes of S3 and S4, about 33 and 200 kb, were resistant to restriction digestion. The lytic cy...

Avian reovirus (ARV) strains cause a variety of symptoms in chickens, including viral arthritis/tenosynovitis, disease that has emerged as significant economic losses commercial chicken flocks recent years various countries, Egypt. Furthermore, ARV are frequently isolated from birds suffering malabsorption. In the actual study, seventy-five samples were collected 2021 and 2022 broiler vaccinate...
