Cross-Reactive Immune Response of Bovine Coronavirus Spike Glycoprotein to SARS-CoV-2 Variants of Concern.

The high variability observed in the clinical symptoms of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infections has been attributed to the presence, in a proportion of infection-naive subjects, of pre-existing cross-reactive immune responses. Here, we demonstrate that the bovine coronavirus spike protein (BoS) may represent a source of protective immunity to SARS-CoV-2. Indeed, vaccination of BALB/c mice with a Bovine herpesvirus 4 (BoHV-4)-based vector expressing BoS induced both cell-mediated and humoral immune responses that cross-react with SARS-CoV-2 spike protein.

Occurrence and molecular prevalence of Anaplasmataceae, Rickettsiaceae and Coxiellaceae in African wildlife: A systematic review and meta-analysis.

Introduction: Tick-borne pathogens (TBPs) constitute an emerging threat to public and animal health especially in the African continent, where land-use change, and wildlife loss are creating new opportunities for disease transmission. A review of TBPs with a focus on ticks determined the epidemiology of Rhipicephalus ticks in heartwater and the affinity of each Rickettsia species for different tick genera. We conducted a systematic review and meta-analysis to collect, map and estimate the molecular prevalence of Anaplasmataceae, Rickettsiaceae and Coxiellaceae in African wildlife.

Evaluation of the Relationship between Pain Exposure and Somatosensory Evoked Potentials in Preterm Infants: A Prospective Cohort Study.

Background And Aim: First, to compare somatosensory evoked potentials (SEPs) in preterm newborns without major brain injury studied at term equivalent age (TEA) with a term historical control group. Second, to investigate the impact of pain exposure during the first 28 days after birth on SEPs. Third, to evaluate the association between SEPs and Bayley-III at 2 years corrected age (CA).
