Coverage from medical teams and injury/illness epidemiology within youth athletics in Africa: A prospective study during the 2023 African Youth Under 18/20 Athletics Championships.

Objectives: To describe athletes' coverage by national medical teams, and injuries and illnesses occurring during the four weeks before and during the 2023 African Youth Under 18/20 Athletics Championships.

Design: Cross-sectional and prospective cohort study design.

Methods: We conducted a study with data collection of: 1) national medical teams, 2) injury and illness complaints during the four weeks preceding the championships using an online pre-participation health questionnaire, and 3) newly incurred in-championship injuries and illnesses collected by national medical teams and the local organising committee using daily standardised online report forms, for all registered athletes at the championships.

Vibrio splendidus clade associated with a disease affecting Paracentrotus lividus (Lamarck, 1816) in Sardinia (Western Mediterranean).

This work reports for the first time the so-called bald sea urchin disease of the populations of Paracentrotus lividus in Sardinia (Italy). Following the disease occurrence reported by local fishermen of about 35% on the collected specimens for commercial purpose, the phenomenon was evaluated in two areas. Animals displayed external lesions represented by loss of spines and greenish/brownish skeleton patches.

Stress and Humoral Innate Immune Response of Gilthead Seabream Sparus aurata Cultured in Sea Cages.

Innate and acquired immune responses of Gilthead Seabream Sparus aurata was studied under normal culture and short-term stressful conditions for 18 months in offshore sea cages in Alghero Bay, Italy. Every 45 d, 50 fish were sampled and divided into two groups: fish in the first group (normal culture conditions) were bled after harvesting; fish in the second group were put into a tank under stressful conditions (crowding and confinement) and bled after 2 h. Innate humoral immunity, such as complement-like, hemagglutination, and lysozyme activities, was determined in the sera of both groups.

Recovery of Staphylococcus aureus in Gray Mugil cephalus Roe (Bottarga): Investigation by an Integrated Cultural/Molecular Approach.

In the Mediterranean area, salted and dried roe from the gray Mugil cephalus "bottarga" represent a speciality food with great commercial value. Bottarga is currently produced by a traditional handmade process and, the risk of human bacterial contamination during its manufacturing is still unknown; in this perspective the foodborne pathogen Staphylococcus aureus could potentially contaminate this product due to poor sanitation or bad handling during processing. The aim of this work is: to evaluate the contamination level of foodborne pathogens at different product manufacturing stages and, in addition, to describe a fast and realizable method for the rapid detection of S.
