Systemic pathological alterations were studied in thirty-seven autopsied patients with Kawasaki disease. Systemic vasculitis was the most characteristic pathological finding and was present in all the patients. In addition to the vasculitis, there was a high incidence of inflammatory lesions in various organs and tissues: in the heart, endocarditis, myocarditis, and pericarditis; in the digestive system, stomatitis, sialoduct-adenitis, catarrhal enteritis, hepatitis, cholangitis, pancreatitis, and pancreas ductitis; in the respiratory system, bronchitis and segmental interstitial pneumonia; in the urinary system, focal interstitial nephritis, cystitis, and prostatitis; in the nervous system, aseptic leptomeningitis, choriomeningitis, gangliontis, and neuritis; in the hematopoietic system, lymphadenitis, splenitis, and thymitis. Dermatitis, panniculitis or myositis were also observed in some patients. Therefore, Kawasaki disease is a systemic inflammatory disease which mainly affects the cardiovascular system. These systemic inflammatory lesions are considered to correspond to the variegated clinical manifestaitions. The relationship between Kawasaki disease and infantile polyarteritis nodosa (IPN) were discussed, based on the clinicopathological characteristics.

In September and October 2002, an epizootic of neurologic disease occurred at an alligator farm in Florida (USA). Three affected American alligators (Alligator mississippiensis) were euthanatized and necropsied, and results confirmed infection with West Nile virus (WNV). The most significant microscopic lesions were a moderate heterophilic to lymphoplasmacytic meningoencephalomyelitis, necrotizing hepatitis and splenitis, pancreatic necrosis, myocardial degeneration with necrosis, mild interstitial pneumonia, heterophilic necrotizing stomatitis, and glossitis. Immunohistochemistry identified WNV antigen, with the most intense staining in liver, pancreas, spleen, and brain. Virus isolation and RNA detection by reverse transcription-polymerase chain reaction confirmed WNV infection in plasma and tissue samples. Of the tissues, liver had the highest viral loads (maximum 10(8.9) plaque-forming units [PFU]/0.5 cm3), whereas brain and spinal cord had the lowest viral loads (maximum 10(6.6) PFU/0.5 cm3 each). Virus titers in plasma ranged from 10(3.6) to 10(6.5) PFU/ml, exceeding the threshold needed to infect Culex quinquefasciatus mosquitoes (10(5) PFU/ml). Thus, alligators may serve as a vertebrate amplifying host for WNV.

Iridoviruses of the genus Ranavirus are well known for causing mass mortality events of fish and amphibians with sporadic reports of infection in reptiles. This article describes five instances of Ranavirus infection in chelonians between 2003 and 2005 in Georgia, Florida, New York, and Pennsylvania, USA. Affected species included captive Burmese star tortoises (Geochelone platynota), a free-ranging gopher tortoise (Gopherus polyphemus), free-ranging eastern box turtles (Terrapene carolina carolina), and a Florida box turtle (Terrepene carolina bauri). Evidence for Ranavirus infection was also found in archived material from previously unexplained mass mortality events of eastern box turtles from Georgia in 1991 and from Texas in 1998. Consistent lesions in affected animals included necrotizing stomatitis and/or esophagitis, fibrinous and necrotizing splenitis, and multicentric fibrinoid vasculitis. Intracytoplasmic inclusion bodies were rarely observed in affected tissues. A portion of the major capsid protein (MCP) gene was sequenced from each case in 2003-2005 and found to be identical to each other and to Frog virus 3 (FV3) across 420 base pairs. Ranavirus infections were also documented in sympatric species of amphibians at two locations with infected chelonians. The fragment profiles of HindIII-digested whole genomic DNA of Ranavirus, isolated from a dead Burmese star tortoise and a southern leopard frog (Rana utricularia) found nearby, were similar. The box turtle isolate had a low molecular weight fragment that was not seen in the digestion profiles for the other isolates. These results suggest that certain amphibians and chelonians are infected with a similar virus and that different viruses exist among different chelonians. Amphibians may serve as a reservoir host for susceptible chelonians. This report also demonstrated that significant disease associated with Ranavirus infections are likely more widespread in chelonians than previously suspected.
