COVID-19 and Semen Fluid Parameters, a Retrospective Study from Infertility Clinics.

The study of the effects of SARS-CoV-2 infection and/or vaccination on semen fluid analysis (SFA) parameters is still incomplete. The aim of this study is to assess the effect of COVID-19 infection and vaccination on sperm parameters for a sample of individuals visiting multi-infertility clinics in Jordan. SFA records were collected retrospectively between September and November 2021 and analyzed using Jamovi software (version 2.

COVID-19 infection and vaccine have no impact on in-vitro fertilization (IVF) outcome.

To investigate the effect of COVID-19 infection or vaccine on IVF outcome. This is a multicenter retrospective study. Data were collected from all patients treated in the ART units between September and November 2021 after the vaccination of the general population began.

Proteomic Analysis of Membrane Blebs of 2308 and RB51 and Their Evaluation as an Acellular Vaccine.

Membrane blebs are released from Gram-negative bacteria, however, little is known about blebs. This work pursued two objectives, the first was to determine and identify the proteins in the membrane blebs by proteomics and analysis. The second aim was to evaluate the use of membrane blebs of 2308 and RB51 as an acellular vaccine and .

Airborne soil particulates as vehicles for Salmonella contamination of tomatoes.

The presence of dust is ubiquitous in the produce growing environment and its deposition on edible crops could occur. The potential of wind-distributed soil particulate to serve as a vehicle for S. Newport transfer to tomato blossoms and consequently, to fruits, was explored.

Immune Response of Calves Vaccinated with Brucella abortus S19 or RB51 and Revaccinated with RB51.

Brucella abortus S19 and RB51 strains have been successfully used to control bovine brucellosis worldwide; however, currently, most of our understanding of the protective immune response induced by vaccination comes from studies in mice. The aim of this study was to characterize and compare the immune responses induced in cattle prime-immunized with B. abortus S19 or RB51 and revaccinated with RB51.
