Salmonella: Case Closed?

A baby in the UK contracted salmonella, and the mother's internet search led to the conclusion that the pet snake was involved... Just a reminder, but many other animals and food products can carry the bacteria. I'd trust a medical report over a quick internet search...

Gharial Investigation Continues

Live gharials are been captured and tested to acquire baseline data, so that researchers can figure out what's killing the species in India. (News source.)

"Post mortem analysis of dead Gharials found ulcerated lesions in the stomach and some inflammation in the intestine. Absence of external injuries rules out accidental death or poaching. Toxicological and pathological examination of the organs of the dead gharials by the IVRI, Bareilly, and ITRC, Lucknow found lead concentrations between 0.7-1.4 ppm. Liver and kidney tissues indicate degenerative changes. Presence of various stages of protozoan parasite was also detected. Autopsies conducted on 4 dead gharials on 27th January, 2008 revealed significant gout – both visceral and articulate. Even the feet and tail joints had uric acid deposits. Gout is indicative of kidney failure as a result of toxic poisoning or disease. However, the gharials seemed in good health condition with fat deposits."

Turtle Amendment Passed?

I haven't really kept up on this, but the Natchez Democrat is reporting that the recently passed Farm, Nutrition and Bioenergy Act of 2007 (H.R. 2419) included an amendment repealing the small turtle sales ban (though noting there may be an effort to repeal the repeal). Turtle farms now process eggs to eradicate Salmonella (or some do, anyway; I'd like to see confirmation that all turtle farms do this). The process goes:

"Once the turtles start to lay their eggs on the levees around the turtle ponds, the eggs are gathered daily, and all dirt is removed from the eggs before they are soaked for 10 minutes in a water and Clorox solution.

"After that, they are cleaned in a commercial washer.
"'We run them through an egg washer manufactured for chicken eggs,' Evans said.
"Once washed, the eggs are placed in a special vacuum tank to eradicate any salmonella. After that, they are placed in incubation trays until they hatch, at which time a state veterinarian certifies they are salmonella free."

[Note: Here is the amendment in question, the Domestic Pet Turtle Equality Act.]

Nutrient Pollution Drives Parasitic Infections

Amphibian deformities derived from parasitic infections are driven by nutrient pollution (increased levels of nitrogen and phosphorus), according to a new study. The nutrients cause algal blooms, which increase the number of snails, which release more parasitic trematodes, which form cysts in amphibians, causing developmental anomalies. (News source.)

CDC and Turtle-Based Salmonella

The CDC has released a report describing 22 cases of turtle-based salmonellosis in 2006 and 2007. One case involved the fatality of a three-week-old child. Interestingly, the report comes out while an attempt is being made by some legislators to lift the CDC ban on small turtle sales. (News source.)

Bacteria Shows Potential for Amphibian Protection

Of several reasons cited for amphibian species decline around the world, the chytridiomycosis fungus is particularly devastating. A bacteria (Pedobacter cryoconitis) found on red-backed salamanders, however, appears to ward off the fungus. Researchers at James Madison University have isolated the bacteria and are conducting experiments that show some early success. Much has yet to be done, but there is potential for a "vaccine" in the future. (News source.)
