Abstract

A wild peninsula ribbon snake (Thamnophis sauritus sackenii) in Florida was found to have hypochromic erythrocytes containing two different types of inclusions: purple granular inclusions, and pale orange or pink crystalloid inclusions that were round, oval, rectangular, or hexagonal in shape. Transmission electron microscopy revealed hexagonal or pleomorphic, homogenous inclusions and enveloped particles morphologically consistent with a member of the Iridoviridae. Histopathology of the animal revealed necrotizing hepatitis consistent with sepsis. Consensus PCR was used to amplify a 628-bp region of iridoviral DNA-dependent DNA polymerase. Bayesian and maximum likelihood phylogenetic analysis found that this virus was distinct from other known iridoviral genera and species, and may represent a novel genus and species.

Anemia

Anemia develops when your blood lacks enough healthy red blood cells. Anemia of inflammation (AI, also called anemia of chronic disease) is a common, typically normocytic, normochromic anemia that is caused by an underlying inflammatory disease. Here is the latest research on anemia.
