Bacillary White Diarrhea __LINK__

Sulphadiazine, Sulphamerazine, sulphapyrazine, Sulphamethazine are the most effective in chicken (not in turkey poults). Furazolidone is effective. Also chloramphenicol, colistin and apromycin are effective. No vaccination practised and all positive birds may be disposed off by slaughter. Birds recently vaccinated with S. gallinarum (9R) may give low titre. Since Tran ovarian transmission of organism is there, only eggs from salmonella free flock should be used for hatching. No treatment is likely to effect complete elimination of carrier from infected birdsAmoxycillin, poteniated sulponamide, tetracylines, fluoroquinolonesHomeopathy For chicks with white foamy diarrhea administer Calc carb + Cala phos, and for adult birds with greenish brown diarrhea administer Sulphur and Ipecac .Always disinfect incubator and all associated equipment prior to use Minimize exposure to environments contaminated by rodent or wild bird feces. Practice good insect control Properly dispose of any dead animal carcasses, do not allow birds contact with dead or decaying animals.

Clinical signs: The severity of infectious bronchitis infection is influenced by the age and immune status of the flock, by environmental conditions, and by the presence of other diseases. Feed and water consumption declines. Affected chickens will be chirping, with a watery discharge from the eyes and nostrils, and labored breathing with some gasping in young chickens. Breathing noises are more noticeable at night while the birds rest. Egg production drops dramatically. Production will recover in 5 or 6 weeks, but at a lower rate. The infectious bronchitis virus infects many tissues of the body, including the reproductive tract (see Table 1). Eggshells become rough and the egg white becomes watery. (See publication PS-24, Egg Quality, for other causes of poor egg quality.)

Species affected: Bobwhite quail are affected. Japanese corturnix quail are resistant. The disease is prevalent in the southern states where bobwhite quail are common. Quail bronchitis occurs seasonally as new hatches and broods come along each year.

Clinical signs: Avian influenza is categorized as mild or highly pathogenic. The mild form produces listlessness, loss of appetite, respiratory distress, diarrhea, transient drops in egg production, and low mortality. The highly pathogenic form produces facial swelling, blue comb and wattles, and dehydration with respiratory distress. Dark red/white spots develop in the legs and combs of chickens. There can be blood-tinged discharge from the nostrils. Mortality can range from low to near 100 percent. Sudden exertion adds to the total mortality. Egg production and hatchability decreases. There can be an increase in production of soft-shelled and shell-less eggs (see Table 1).

Clinical signs: Clinical signs in most birds include nasal-ocular discharge, conjunctivitis, sinusitis, diarrhea, weakness, loss of body weight, and a reduction in feed consumption. In turkeys there is also respiratory distress and loose yellow to greenish-yellow colored droppings. Chylamydiosis runs rather slowly through turkey flocks, with a maximum incidence of around 50 percent (see Table 1).

Clinical signs: Birds infected with the synovitis form show lameness, followed by lethargy, reluctance to move, swollen joints, stilted gait, loss of weight, and formation of breast blisters. Birds infected with the respiratory form exhibit respiratory distress. Greenish diarrhea is common in dying birds (see Table 1). Clinically, the disease in indistinguishable from MG.

Clinical signs: Marek's disease is a type of avian cancer. Tumors in nerves cause lameness and paralysis. Tumors can occur in the eyes and cause irregularly shaped pupils and blindness. Tumors of the liver, kidney, spleen, gonads, pancreas, proventriculus, lungs, muscles, and skin can cause incoordination, unthriftiness, paleness, weak labored breathing, and enlarged feather follicles. In terminal stages, the birds are emaciated with pale, scaly combs and greenish diarrhea (see Table 2).

Clinical signs: The virus involved has a long incubation period (4 months or longer). As a result, clinical signs are not noticeable until the birds are 16 weeks or older. Affected birds become progressively weaker and emaciated. There is regression of the comb. The abdomen becomes enlarged. Greenish diarrhea develops in terminal stages (see Table 2).

Prevention: The virus is present in the yolk and egg white of eggs from infected hens. Most national and international layer breeders have eradicated lymphoid leukosis from their flocks. Most commercial chicks are lymphoid-leukosis negative because they are hatched from LL-free breeders. The disease is still common in broiler breeder flocks.

Clinical signs: There are no reliable signs other than the effects on egg production and egg quality. Healthy-appearing hens start laying thin-shelled and shell-less eggs. Once established, the condition results in a failure to achieve egg production targets. Transient diarrhea and dullness occur prior to egg shell changes. Fertility and hatchability are not affected (see Table 2).

Clinical signs: Fowl cholera usually strikes birds older than 6 weeks of age. In acute outbreaks, dead birds may be the first sign. Fever, reduced feed consumption, mucoid discharge from the mouth, ruffled feathers, diarrhea, and labored breathing may be seen. As the disease progresses birds lose weight, become lame from joint infections, and develop rattling noises from exudate in air passages. As fowl cholera becomes chronic, chickens develop abscessed wattles and swollen joints and foot pads. Caseous exudate may form in the sinuses around the eyes. Turkeys may have twisted necks (see Table 3).

Clinical signs: Initially there is a reduction in feed consumption as well as dark, often blood-stained, feces. Infected chickens will have diarrhea. Chronically affected birds become emaciated. The bird, intestines, and feces emit a fetid odor (see Table 3).

Salmonella pullorum is the etiologic agent of bacillary white disease otherwise called pullorum disease [4] . In Nigeria and all over the world, pullorum disease is said to be of high incidence [4] [10] [11] [12] . Infected layers may become chronic carriers and transmit the organism to their embryos through the eggs [13] . Egg transmission may result from contamination of ovum following ovulation or localization of the bacterium in the ovum before ovulation [4] [6] . Chicks can also be infected through chick-to-chick contact, bird-to-bird contact, cannibalism of infected carcasses, wound contamination, fecal contamination of water or feed [4] [13] . Wild birds, rats and insects also act as vectors in transmission of Salmonella pullorum in poultry and other aviaries [12] [14] . Contamination between birds may also occur by introduction of infected sub clinically sick birds into the production chain. Morbidity and mortality are usually high within 2 - 3 weeks of age. Chicks and poults may develop nonspecific signs like depression, weakness, somnolence, loss of appetite, droopy wings, dehydration and ruffled feathers [15] . Necropsy findings in young chicks that die of pullorum disease may include, unabsorbed yolk sacs, peritonitis, grayish nodules in the liver, heart, spleen, lungs, gizzard and intestines [5] [6] [13] [15] . The liver, kidneys and spleen are often congested and enlarged, with dilatation of subcutaneous blood vessels [16] The ceca may be enlarged and contain firm cheesy materials called cecal cores [5] [16] .

Shigellosis is a bowel infection caused by bacteria from the Shigella family. Other names for shigellosis include Shigella infection, Shigella enteritis and bacillary dysentery. Common symptoms include diarrhoea that may contain blood, mucus or pus, abdominal cramps, nausea and vomiting.

It is important that the hatchery you select to get your chickens, turkeys or waterfowl be NPIP-approved. The National Poultry Improvement Plan is a voluntary program developed in 1935 to eradicate Bacillary white Diarrhea (BWD) cuased by Salmonella pullorum. S. pullorum can be transmitted through the egg from hen to chick. By screening breeding stock the occurence of Salmonella pullorum is now very low.

Bacillary white diarrhea in chickens was a major disease concern for the poultry industry during the early 1900s. Drs. L. F. Rettger and W. R. Hinshaw organized a meeting in 1928 to discuss methods for controlling this disease. In this meeting, representatives of five northeastern states discussed approaches to test for the presence of the etiological agent of bacillary white diarrhea, namely, Salmonella enterica subsp. enterica serovar Pullorum. Meeting attendees decided to have a yearly meeting of the Northeastern Conference of Laboratory Workers in Bacillary White Diarrhea. The next year, the name was changed to Conference of Laboratory Workers in Pullorum Disease Eradication, which was changed to Northeastern Conference on Avian Diseases (NECAD) in 1957. Not only has NECAD been important for the control of pullorum disease but also, starting with the fifth Annual Conference in 1932, other poultry diseases became an official part of the program. As such, NECAD served for a long time as the premier organization to present new information on avian diseases. The success of NECAD was based on the work of the many committees, which are described in detail in this review. For example, the antigen committee started officially in 1929 and remained active until at least 1987. The main task of this committee was to evaluate Salmonella Pullorum strains to be used by all participants in the pullorum antibody testing programs. NECAD started as a closed organization with participants from universities and government organizations but did not allow representatives from commercial groups until 1968 when all American Association of Avian Pathologists (AAAP) members in the Northeastern United States could participate. The journal Avian Diseases started with discussions by Dr. P. P. Levine with M. S. Cover, H. L. Chute, R. F. Gentry, E. Jungherr, and H. Van Roekel about the idea that NECAD would sponsor a journal dealing specifically with avian diseases. During the first few years of Avian Diseases publication, many articles including abstracts came from the NECAD Annual Conferences. The importance of NECAD as a precursor for other regional meetings and the AAAP and as a forum for graduate students to present their research are described. Several recipients of the award for the best paper presented by a graduate student have continued to work in avian disease research. The decline in the participation of scientists in the late 1990s and early 2000s was discussed extensively in 2006 and led to a merger of the NECAD meeting with the Pennsylvania Poultry Sales and Service Conference. Due to the COVID-19 pandemic, the 92nd Annual Conference was a virtual meeting in 2020. Fortunately, the 93rd Annual Conference in 2021 was an in-person meeting held in State College, PA. 041b061a72
