Assessment of phagocytic activity of tilapia blood cells under hormone-induced stress

Submitted by red on Sun, 12/06/2022 - 16:16

The paper presents an assessment of the phagocytic ability of blood cells of Nile tilapia Oreochromis niloticus L. under the hormonal induction of stress with range of duration. It has been revealed that Staphylococcus aureus is phagocytosed by leukocytes, platelets, and erythrocytes of tilapia blood in direct smears. The phagocytic capacity of the cells has been quantified.

Submitted by red on Tue, 10/09/2019 - 09:40

This paper presents an assessment of changes in some indicators of the immune system in the control and experimental group of carp under the influence of endogenous cortisol. It was found that when the level of cortisol increases the activity of cellular immunity in fish created by leukocytes increases as well. Other indicators of the immunological status decrease with the increase of this hormone.
