Detection of Chronic Wasting Disease Prions in Prairie Soils from Endemic Regions.

Chronic wasting disease (CWD) is a contagious prion disease that affects cervids in North America, Northern Europe, and South Korea. CWD is spread through direct and indirect horizontal transmission, with both clinical and preclinical animals shedding CWD prions in saliva, urine, and feces. CWD particles can persist in the environment for years, and soils may pose a risk for transmission to susceptible animals.

BAITING AND BANDING: EXPERT OPINION ON HOW BAIT TRAPPING MAY INFLUENCE THE OCCURRENCE OF HIGHLY PATHOGENIC AVIAN INFLUENZA (HPAI) AMONG DABBLING DUCKS.

A Eurasian lineage highly pathogenic avian influenza virus (HPAIV) of the clade 2.3.4.

HEPATIC TO PULMONARY EMBOLISM OF ABSORBABLE GELATIN HEMOSTATIC SPONGE IN TWO EGYPTIAN FRUIT BATS ().

In a study on iron regulation, liver biopsies were collected at two time points from 34 adult Egyptian fruit bats (). An absorbable gelatin hemostatic sponge (GS) was inserted at biopsy sites for local hemostasis in 16 bats. In the subsequent 10 yr, 12 of these bats died or were euthanized, and 11 were examined histologically; in 2 bats, intravascular GS was identified in the lungs and in 1 bat, unabsorbed GS was also identified at the hepatic biopsy site.

Batrachochytrium salamandrivorans (Bsal) not detected in an intensive survey of wild North American amphibians.

The salamander chytrid fungus (Batrachochytrium salamandrivorans [Bsal]) is causing massive mortality of salamanders in Europe. The potential for spread via international trade into North America and the high diversity of salamanders has catalyzed concern about Bsal in the U.S.

Iron storage disease (hemochromatosis) and hepcidin response to iron load in two species of pteropodid fruit bats relative to the common vampire bat.

Hepcidin is the key regulator of iron homeostasis in the body. Iron storage disease (hemochromatosis) is a frequent cause of liver disease and mortality in captive Egyptian fruit bats (Rousettus aegyptiacus), but reasons underlying this condition are unknown. Hereditary hemochromatosis in humans is due to deficiency of hepcidin or resistance to the action of hepcidin.

Widespread distribution of ticks and selected tick-borne pathogens in Kentucky (USA).

The geographical distribution of Ixodes scapularis and Amblyomma maculatum ticks is poorly understood in Kentucky. We conducted a convenience survey of wildlife species (white-tailed deer (Odocoileus virginianus), elk (Cervus canadensis) and black bears (Ursus americanus)) for ticks from October 2015 to January 2017. We detected four tick species including Amblyomma americanum, Dermacentor albipictus, I.

A RETROSPECTIVE STUDY OF THE LESIONS ASSOCIATED WITH IRON STORAGE DISEASE IN CAPTIVE EGYPTIAN FRUIT BATS (ROUSETTUS AEGYPTIACUS).

Egyptian fruit bats (Rousettus aegyptiacus) are one of many species within zoologic collections that frequently develop iron storage disease. The goals of this retrospective multi-institutional study were to determine the tissue distribution of iron storage in captive adult Egyptian fruit bats and the incidence of intercurrent neoplasia and infection, which may be directly or indirectly related to iron overload. Tissue sections from 83 adult Egyptian fruit bats were histologically evaluated by using tissue sections stained with hematoxylin and eosin, trichrome, and Prussian blue techniques.

Gastrolithiasis in prehensile-tailed porcupines (Coendou prehensilis): nine cases and pathogenesis of stone formation.

Gastrolithiasis was diagnosed in nine prehensile-tailed (PT) porcupines (Coendou prehensilis) housed at six zoologic institutions in the United States and Canada. Affected animals were either asymptomatic or had clinical signs, including weight loss, diarrhea, and depression. Abdominal palpation was adequate for diagnosis in all six antemortem cases, and radiographs confirmed a soft tissue density mass effect produced by the concretion.

Description of two new Isospora species causing visceral coccidiosis in captive superb glossy starlings, Lamprotornis superbus (Aves: Sturnidae).

Isospora greineri sp. n. and Isospora superbusi sp.

Characterization of the hepcidin gene in eight species of bats.

Hemochromatosis, or iron storage disease, has been associated with significant liver disease and mortality in captive Egyptian fruit bats (Rousettus aegyptiacus). The physiologic basis for this susceptibility has not been established. In humans, a deficiency or resistance to the iron regulatory hormone, hepcidin has been implicated in the development of hereditary hemochromatosis.
