The disease affects all ages of chickens. The disease can persist in the flock for 2-3 weeks and signs of the disease are seen 1–3 days after infection. Transmission of the disease is through direct interaction, airborne droplets, and drinking contaminated water. Chickens having infection and those carriers contribute highly to the disease ...
Tularemia, also known as rabbit fever, is an infectious disease caused by the bacterium Francisella tularensis. [4] Symptoms may include fever , skin ulcers , and enlarged lymph nodes . [ 3 ] Occasionally, a form that results in pneumonia or a throat infection may occur.
As this organism is more common in animals than people it is likely a zoonotic disease. Three different strains of E. cuniculi have been identified, and are classified as I (rabbit), II (mouse), and III (dog). [8] Human-to-human transmission is possible via transplantation of solid organs from an infected donor. [12]
Most cases of humans contracting rabies from infected animals are in developing nations. In 2010, an estimated 26,000 people died from the disease, down from 54,000 in 1990. [6] The World Health Organization (WHO) reports that dogs are the main source of human rabies deaths, contributing up to 99% of all transmissions of the disease to humans. [7]
The human diploid cell rabies vaccine was started in 1967. Less expensive purified chicken embryo cell vaccine and purified vero cell rabies vaccine are now available. [69] A recombinant vaccine called V-RG has been used in Belgium, France, Germany, and the United States to prevent outbreaks of rabies in undomesticated animals. [77]
Infectious bursal disease (IBD), also known as Gumboro disease, infectious bursitis, and infectious avian nephrosis, is a highly contagious disease of young chickens and turkeys caused by infectious bursal disease virus (IBDV), [1] characterized by immunosuppression and mortality generally at 3 to 6 weeks of age.
While the human life span has increased markedly since the 19th century, new research shows that despite recent advancements in medicine, we may have reached our longevity peak—and most of today ...
The symptoms are highly fatal to turkeys, but effect less damage in chickens. However, outbreaks in chickens may result in high morbidity, moderate mortality, and extensive culling, leading to overall poor flock performance. [3] Concurrence of Salmonella typhmurium and E. coli was found to cause high mortality in broiler chickens. [6]
