Massive Africanized honeybee stings in two hair sheep and a mare.

This study reports on the severe effects of massive Africanized honeybee stings on two hair sheep and a mare, causing death, skin damage, and internal organ harm in the animals.

Summary of the Research

The research discusses the extensive injuries caused by a significant attack of Africanized honeybees on two hair sheep and a mare. The symptoms included:

• Skin necrosis (skin cell death) at the sting sites in the survivors.
• In one of the sheep, the attack resulted in death 15 hours post-assault.

Pathological Evaluation

A thorough pathological examination of the affected animals was carried out. The analysis revealed:

• Necrosis in the dermis layer of their skin. Necrosis is a severe cell injury leading to premature death of cells in living tissue.
• Signs of degeneration in the tubular epithelial cells, which are cells in the kidneys involved in the process of filtration and reabsorption.
• Existence of multifocal hemorrhages (spots of bleeding) in the heart and spleen of the animals. This scenario suggests damage to these organs.

Systemic Impact of the Bee Attack

The research shows that the attack from the Africanized honeybees resulted in systemic lesions, meaning injuries distributed throughout the body of these animals, not just limited to the area of the bee stings. Some of the impacted organs included:

• Skin: Damages resulted in necrosis or cell death at the sites of the bee stings.
• Heart: The presence of multifocal hemorrhages, demonstrating potential damage due to the venom.
• Muscles: Although not specified, the summary suggests the bee venom may have induced some level of harm.
• Kidneys: Degeneration of tubular epithelial cells may indicate disruption to the function of these organs.
• Lungs: Similar to the muscles, it isn’t explicitly mentioned, but the summary hints at potential damage to these organs.
