- Honey bees (Apis mellifera) are crucial pollinators, and their immune response varies between summer and winter seasons, influenced by factors like lifespan, behavior, and seasonality.
- The study utilized Bayesian statistics to analyze the immune responses of honey bee workers to a bacterial pathogen, focusing on both humoral and cellular immune reactions through various assays and analyses.
- Findings revealed that winter bees exhibited a stronger overall immune response, relying more on humoral reactions, while summer bees showed a cellular reaction with increased hemocyte concentration after exposure to the heat-killed bacteria.
The fungal pathogen can induce prolonged colonization of the lungs of susceptible patients, resulting in conditions such as allergic bronchopulmonary aspergillosis and chronic pulmonary aspergillosis. Analysis of the secretome released during sub-lethal infection of larvae may give an insight into products released during prolonged human colonisation. larvae were infected with and the metabolism of host carbohydrate and proteins and production of fungal virulence factors were analysed.

We evaluated the effects of two insecticides (fipronil, sulfluramid) and metallic insecticide complex (magnesium complex [Mg(hesp)2(phen)] (1)) on the superoxide dismutase (SOD), glutathione (GSH) and the overall antioxidant capacity using two different methodologies: total radical-trapping potential (TRAP) and oxygen radical absorbance capacity (ORAC). Media workers of Atta sexdens (C.

- The study investigates a natural outbreak of carp edema virus disease (CEVD) in koi carp, focusing on various aspects such as clinical symptoms, pathology, immune responses, and viral detection methods.
- Findings revealed significant changes in white blood cell counts, with increased monocytes and decreased lymphocytes in affected fish, alongside heightened phagocytic activity.
- Additionally, the research identifies new histopathological damage in the pancreatic tissue of diseased koi carp, contributing to a deeper understanding of CEVD pathology.
