polio in cattle symptoms

Polio is a highly contagious viral infection that causes paralysis, breathing problems, and may be fatal. Byproducts of corn, sugar cane, and sugar beet processing commonly have a high sulfur content, apparently due to the addition of sulfur-containing acidifying agents. In particular, vitamin A and E can be common causes of lost profit, secondary to limitations of reproductive and growth potential. The most common cause of PEM is thiamine deficiency. Those with a longer duration of acute signs have poorer responses to therapy and higher mortality. At later stages, the affected cortical tissue undergoes cavitation as macrophages infiltrate and necrotic tissue is removed. Which of the following conditions can also cause laryngeal paralysis? Although not discussed in textbooks, consulting veterinarians tell me there is a condition known as the nervous form of coccidiosis. Kids are more susceptible to polio than adults. If the problem can be associated with a high sulfur intake, all possible sources of sulfur, including water, should be analyzed and the total sulfur concentration of the consumed dry matter estimated. The main clinical signs reflect dysfunction of the cerebrum and include wandering, circling, cortical blindness, incoordination, head pressing, recumbency, nystagmus, and seizure activity. Acutely affected animals may have brain swelling with gyral flattening and coning of the cerebellum due to herniation into the foramen magnum. Polioencephalomalacia (Polio) Consider your mindset for 2021 and beyond, Cattlemen's Update to examine market, production, research, 7 ag stories you might have missed this week - Jan. 8, 2021, Ag groups file additional comments on FMD vaccine, Nufarm announces Grassmanship Scholarships. Beef Magazine is part of the Informa Markets Division of Informa PLC. Polio is most common in rapidly growing cattle fed a high-concentrate diet because this class of animals are more likely to encounter risk factors that lead to decreased thiamine activity.

The byproducts can have enough sulfur to cause polio in cattle. This site complies with the HONcode standard for trustworthy health information: If your lamb bumps into things that it ordinarily would see and avoid, he may be showing signs of blindness.

Dietary supplementation of thiamine at 3–10 mg/kg feed has been recommended for prevention, but the efficacy of this approach has not been carefully evaluated. When the problem could be associated with high sulfur intake, all possible sources of sulfur, including water, should be analyzed and the total sulfur concentration of the consumed dry matter estimated. Suspected based on clinical signs and response to thiamine; confirmed by necropsy. Some animals are found dead. The neurons are shrunken and have homogeneous, eosinophilic cytoplasm.

Polio is a virus that spreads easily between people who aren't vaccinated. Most feedlot veterinarians will routinely instruct feedlot "doctors" in how to treat polio, and likewise thiamin and glucose will be kept on hand. Dietary ingredients or water with high sulfur concentration should be avoided; if this is not possible, then more gradual introduction to the new conditions can improve the chances of successful adaptation. Tetanus is caused by toxins produced by the bacterium Clostridium tetani. Cattle with polio display symptoms of listlessness, incoordination and convulsions. In this case, a little extra money to hire conscientious cowboys can save several times as much in unnecessary (and probably ineffective) thiamin. Therapy must be started early in the disease course for benefits to be achieved. Death may occur within a few hours after onset of the disease. They can either destroy thiamine or form antimetabolites that interfere with thiamine function. Thiamine is especially important for proper brain function as the brain relies on glucose as its major source of energy. Watch for symptoms. During a PEM outbreak, sufficient roughage should be provided. Animals with the subacute form initially separate from the group, stop eating, and display twitches of the ears and face. Although nonreduced forms of sulfur, such as sulfate and elemental sulfur, are relatively nontoxic, H2S and its various ionic forms are highly toxic substances that interfere with cellular energy metabolism. There is a high incidence of intestinal carriers. The treatment of choice for polioencephalomalacia regardless of cause is thiamine administration at a dosage of 10 mg/kg, three to four times daily, for cattle or small ruminants.
