**Bogotá, Colombia** – A new study published in PLOS ONE has identified a potential solution for the nutritional challenges faced by orphaned manatee calves. Researchers at the Universidad de Los Andes have discovered that human immunoglobulin A (IgA), a crucial component of breast milk, shares remarkable similarity with its counterpart in the American manatee (Trichechus manatus).

Manatee calves rely heavily on their mothers’ milk for immune support and proper development. However, commercially available milk substitutes often lack key components, including IgA, which plays a vital role in building a strong immune system and fostering a healthy gut microbiome.

“This lack of suitable substitutes poses a significant conservation challenge,” explains lead author Miguel Díaz-Yayguaje. “Orphaned calves frequently struggle to recover and thrive, potentially leading to various health problems.”

The study employed advanced computational tools to compare the amino acid sequences, 3D structures, and potential binding sites (epitopes) of manatee IgA with those of several other species. Their findings revealed that human IgA exhibited the highest degree of similarity in all three aspects.

“This similarity suggests that human anti-IgA antibodies, particularly polyclonal ones, could be used to detect and potentially even quantify manatee IgA in milk samples,” notes Dr. Ana Valderrama-Aguirre, a senior researcher involved in the project. “This would be a significant breakthrough in our understanding of manatee immunity and could lead to improved care for orphaned calves.”

This research opens exciting new avenues for manatee conservation. The ability to readily identify and measure IgA levels in orphaned calves could lead to tailored nutritional plans and ultimately, better health outcomes.

The research team is currently conducting in-depth functional studies to confirm their findings and explore the full potential of human IgA antibodies for manatee conservation.
