Poultry as a reservoir for foodborne disease - News & …

The quest to determine of origin of Oroya fever and verruga peruana was stimulated by Peru’s drive to exploit the mineral wealth of the Andes. Likewise, the settlement of Montana’s Bitterroot Valley prompted efforts to deduce the organism and vector responsible for Rocky Mountain Spotted Fever (). Many discoveries in tropical infectious diseases, including those of the vectors of yellow fever, malaria, and lymphatic filariasis, were also stimulated by the acquisition of colonies by the United States and Great Britain.

During the 19th century, cholera spread repeatedly in 6 pandemic waves, moving from the Bay of Bengal to most of the world. During the first half of the 20th century, the disease was confined largely to Asia, except for a major epidemic in Egypt in 1947. The current worldwide occurrence of cholera -- termed the 7th pandemic -- started in 1961. Cholera of the El Tor biotype (i.e., the same biotype as in Haiti) spread worldwide from Indonesia, reaching the Asian mainland in 1963, and Africa in 1970. The disease has has remained epidemic in many countries of Asia and Africa. After nearly a century of absence,cholera reached Latin America in 1991, causing explosive epidemics in many countries, including Peru. By 1994, approximately one million cholera cases had been recorded in Latin America. While the 7th pandemic was underway, scientists began to recognize environmental reservoirs of cholera, including the coastal waters of the Gulf of Bengal and in the southern United States by the Gulf of Mexico. As noted by Cairncross, by the 1980sVibrio cholerae became viewed as not just a human pathogen spread from feces to mouth, but rather as an aquatic bacterium which can survive in coastal waters for long periods of time, and then infect humans (3, 4).

You will often hear people say, "That's only a theory", "That's not proven", "Medical schools do not teach the true causes of disease", or "Seventy percent of what you're taught in medical school is proven wrong within ten years." To give thoughtful answers, you need to know the following definitions of things that make up the business of science: Fact: (1) A simple observation anybody can make (for example, grass is green, my shoe is untied, it is raining today).
