Many Oklahoma and Arkansas poultry producers have had to deal with  the poultry disease known as "LT".  The virus, known as “LT”, belongs to the herpes group and causes infectious laryngotracheitis. LT does not transmit to humans but can cause one percent mortality per day in flocks in a typical outbreak. LT is NOT the Avian flu.

 The first confirmed outbreak of LT was in northwest Arkansas in September according to a letter from one poultry company. Chickens and pheasants are natural hosts the disease, Most outbreaks are traced to transmission by visitors, shoes, clothing, egg boxes, used feeders, waterers, cages, and crates. The incubation period varies from four to 12 days.

Birds will show respiratory distress due to built up blood, sloughed tracheal lining and even caseous exudates in the larynx and trachea. Affected chickens will have a difficult time breathing and will frequently die of suffocation. Some birds show symptoms of gasping with the head extended and the beak open. Chickens 14 weeks and older are more susceptible than young chickens. LT is confirmed in birds that test positive through a fluorescent antibody test.

Birds can be vaccinated for LT to prevent outbreaks and epidemics. Broiler flocks should be vaccinated before six weeks of age. Birds retained for breeder and other adult bird purposes should be re-vaccinated to assure immunity.

Bio-security measures include controlling visitors to the farm, quarantine farm, tighten farm security, have a separate caretaker for sick flock, stop cross traffic to other poultry, upgrade sanitation, incinerate dead birds, administer antibiotics, do not allow any other fowl, game fowl or feathered animals on the farm, stay away from infected farms, and vaccinate flock.
