Emerging wildlife diseases pose a significant threat to natural and human systems. Because of real or perceived risks of delayed actions, disease management strategies such as culling are often implemented before thorough scientific knowledge of disease dynamics is available. Adaptive management is a valuable approach in addressing the uncertainty and complexity associated with wildlife disease...
Approximately five million live ruminants are imported annually into Saudi Arabia. The majority of these animals are imported shortly before the pilgrimage season from Sudan and the Horn of Africa, where foot and mouth disease (FMD) is known to be enzootic. This study was designed to investigate the impact of the importation of these live ruminants on the epizootiology of FMD in Saudi Arabia. T...
An epizootic of duck plague occurred in early 1973 in a population of 163,500 wild waterfowl, primarily mallards (Anas platyrhynchos), wintering on Lake Andes and the nearby Missouri River in southeastern South Dakota (USA). The diagnosis was based on pathologic lesions and confirmed by virus isolation. Control measures included quarantine, attempts to reduce virus contamination of the area, di...
An immunodiffusion test using foot and mouth disease (FMD) virus infection-associated (VIA) antigen was used to detect precipitating antibodies in serum samples collected from non-vaccinated indigenous ruminants raised in different regions of Saudi Arabia. Of 5,985 sheep sera, 1,371 goat sera, 1,052 cattle sera and 694 serum samples from unspecified species of ruminants, precipitating activity ...
The study of coral diseases, coral pathogens, and the effects of diseases on tropical and subtropical coral reefs are all current, high-profile research areas. This interest has grown steadily since the first report of a coral disease in 1973. The author of this report was Arnfried Antonius and the publication was an abstract in the proceedings of a scientific meeting of the Association of Mari...
The role of introduced avian malaria Plasmodium relictum in the decline and extinction of native Hawaiian forest birds has become a classic example of the potential effect of invasive diseases on biological diversity of naı̈ve populations. However, empirical evidence describing the impact of avian malaria on fitness of Hawai ì’s endemic forest birds is limited, making it difficult to determine t...
To study the susceptibility of wading birds to eastern equine encephalitis (EEE) virus and to determine their potential as reservoir or amplifying hosts, fledgling glossy ibises (Plegadis falcinellus) and snowy egrets (Egretta thula) were captured in New Jersey (USA) and shipped to Colorado (USA) where they were experimentally inoculated with EEE virus. All 16 snowy egrets and 14 (93%) of 15 of...
365 sera samples were collected during 1997 from two groups of camels in Sharkia governorate, Egypt. The first group: 190 sera samples collected from slaughtered camels at Belbas abattoir, while the second group: 175 sera samples collected from individual camels which were in contact with cattle herds. Sera samples were tested by serum neutralization test for the presence of antibodies against ...
