Anti-inflammatory Effect of Metronidazole in Hospitalized Patients with Pneumonia due to COVID-19.

Metronidazole (MTZ) can decrease the levels of several cytokines. This research aimed at the investigation of the anti-inflammatory impact of MTZ in COVID-19. A randomized, single-blind clinical trial for comparing the anti-inflammatory effect of MTZ in two eligible groups of adult patients with lower respiratory tract involvement due to Covid-19 treated with a standard national method with or without MTZ was performed.

Production of IgY polyclonal antibody against diphtheria toxin and evaluation of its neutralization effect by Vero cell assay.

Background: Diphtheria is a bacterial disease which is caused by Corynebacterium diphtheriae. The symptoms are due to the diphtheria toxin produced by the bacteria. Antibiotic therapy and the use of diphtheria antitoxin is a recommended strategy to control diphtheria.

In vitro evaluation of cross-strain inhibitory effects of IgY polyclonal antibody against H. pylori.

The present study aimed to evaluate in vitro cross-strain inhibitory effects of IgY polyclonal antibody on both growth and urease enzyme of four local strains of H. pylori. Leghorn chickens were immunized with whole cells of four different strains of H.
