Recently, researchers have made exceptional progress in developing a vaccine for Lyme disease, which may also help in its eradication. In 1975, researchers have made exceptional progress in develop ing a vaccine for Lyme disease, which may also help in its eradication. In 1975, researchers investi gated several cases of childhood arthritis in Old Lyme, Connecti cut, and determined that they were caused by a tick-borne infection, known as Lyme disease. In 1982, National Institute of Health (NIH) researcher Willy Burgdorfer iden tified a corkscrewshaped bacteria, subsequently named Borrelia burgdorferi, as the culprit Ani- V' s >- % ; f/, *\ ' WW 1 J*' '- * {• % S\ , f „ r 36 mot"*' 8 9 - 9% Si* w v i£ - s BINKLEY & HURST BROS. 133 Rothsvllla Station Rd.

When ticks feed on these animals they ingest the germ, then pass it along to the next animal or human they bite. Humans may develop a circu lar, red area around the bite. Initial symptoms can mimic a mild case of flu. If Lyme disease is left untreated, rashes, arthritis, abnor mal heart rhythms, nerve damage, and memory loss can develop. If properly diagnosed, prompt treat ment with antibiotics prevents theser late effects.

Vaccine develop ment, however, was hampered by the lack of a suitable animal model most animals harbor the Borre lia germ without developing the disease. However, after a year of searching, a susceptible strain of mice was identified. Researchers also found that hamsters with suppressed immune systems could contract Lyme disease. Using these animal models, a vaccine based on killed Borrelia was developed, and in 1990 it was approved to protect dogs. Recen tly, a vaccine using a genetically engineered Borrelia protein has been shown to be effective in ani mals. Preliminary human trials began in October, 1992, and if successful, the vaccine may EHL V v' cf’ LINCOLN SUPPLY & GUTSHALL’S, INC. EQUIPMENT CO. RD2Rtaasow RR 02, Box 217 A Uoyawillo.

A surprising, unprecedented benefit of the genetically engi neered vaccine is that in addition to protecting the animal, the vac cine also kills the Borrelia within the carrier tick. This opens the possibility of widespread disease control by vaccinating animal hosts, with the long-term goal of elimination of the disease. If so, strollers through the woods one day may not have to worry about anything more threatening than bears and poison ivy.

Ag Trade Helps U.S. Economy Farmers help the United States economy by creating a large, favorable trade balance of U.S. agricultural exports over agricultur al imports. The United States is the world’s largest exporter of agricultural products ($40.2 billion worth annually). The United States is.- overwhelmingly an industrial nation; only 2 percent of the popula tion works on farms. But U.S. farmers are so productive that agricul ture still accounts for all U.S. exports. The pro duction from one out of every 2.5 acres of crop land harvested is exported. The great productivi ty of U.S. farms allows us to use all of the farm products we can inside the United States, and still be able to sell 69 percent of our wheat, 41 percent of our com, 59 percent of our soybean products and more than 50 percent of our cotton to earn income in fore ign countries. U.S. farm productivi ty helps the nation hold strong market shares in the worldwide market for farm products. The U.S. shares of important crop markets are on the order of 37 percent of world wheat exports, 86 percent of world soy bean exports and 21 percent of world rice exports. Looking at it another way, U.S. farmers have developed their exports to a point where 25 per cent of the income they generate to keep their {operations going comes from foreign consumers instead of U.S. consum ers. The huge export industry that U.S. farm productivity is able to keep supplied employs more than a million people in the United States. Each dollar’s worth of U.S. farm commodities exported generates about $1.59 in additional economic activity in finance; transportation; wareh ousing; and farm supply manufacturing, distri bution and sales.
