The incidence and prevalence of disease spread Paratyfvyyd edx particularly severe Salmonella typhimurium in the US and Australia in 1978 caused a lot of damage (4) .drty 1980s most contaminated eggs in the northwestern United States are infected with Salmonella enteritidis in eggs may Bvdvtqryba 0001/0 Dhd.dr these areas occur on average every 50 consumers edx in the eggs, one can be infected with Salmonella (12). The occurrence of the disease in the cold months and 2% higher in males (10). The disease is pathogenic serotypes Hazrshaytryn Paratyfvyyd in Tyv, Salmonella edx enteritidis Salmonella enteritidis, S. typhimurium Vsalmvnla are S.typhimurium (1). These factors, gram-negative, rod-shaped with dimensions of 5 / 1- 7/0 5-2 capsules that are free and no spores. Has a long and Mthrknd Tazhk hay. In the temperature range from 5 to 45 C Vdrmhdvdh pH, 4 to 9 Rshdknnd (6) and nitrate to nitrite revive (1). Salmonella typhimurium fermentation of glucose (also produce acid and gas), Dvlsytvl, mannitol, maltose do it but is unable to ferment lactose, sucrose, is Malone or saline. Hydrogen sulfide is produced edx in all environments and decarboxylation does Vlyzyn Oren tin and citrate as carbon source utilization is important. Salmonella typhimurium and gelatin hydrolysis of urea does not produce the indole (6). Zyrdvhftgy Mmvlabymary clinical signs in chickens and rarely seen at 4 weeks of age (1). Mmvlatlfat edx in less than 20% of cases occurring during edx the second edx week of life, the chicks can be a symptom of weak growth, stunted growth and general weakness of the body can show (11). Paratyfvyyd infection in very young birds are causing the disease (7). Eggs contaminated with Salmonella can result in the death of the fetus inside the eggs or newly hatched chicks rapid death, cause. Clinical symptoms are rarely seen after two weeks (6). Birds with bored, depressed .tmayl squatted and not moving with closed eyes, ruffled feathers and wings down and say. Diarrhea, fecal contamination of feathers surrounding the anus with a common manifestation of (7) and in the haze of contagious or cheese plate in the eye socket, bird vision problems (1). Rarely edx cause disease in poultry laying hens and egg production is reduced if the disease edx (6). According to a 1995 study conducted in the US, the seeds that were suspected to Fazhtyp edx 4 Salmonella enteritidis were some deficiencies in the shell of including elongation of the egg shell is thin, small, crooked to the eggs (16). Generally edx 4 phage strains that are common in Europe edx and Asia and Iran are far more virulent than other strains prevalent edx in the United States and Canada (21). Autopsy findings edx in newly hatched chicks Rfvnt severe that it leads to a rapid loss of body only necropsy septicemia (6). If the chicks are in the early years of suffering, and the absorption of the yolk sac inflammation edx is common in them (1). If they do not disappear during the acute septicemia often accompanied by swelling of the spleen and liver congestion, veins, blood and necrotic foci are seen. Kidneys may be affected pericarditis, viral hepatitis Perry fibrin seen many cases (6). The autopsy findings indicated that about dead birds seen salmonellosis caused by dilated cecum Sfydv necrotic material that is hard to say Typhitis nadir value (1) When the disease becomes chronic, acute enteritis with foci of necrosis in the small intestine includes opacity of the eye, especially the eyes, swelling, pus and inflammation of the air sacs (6). Confirmation of diagnosis requires isolation and identification of the causative serovar Vtrjyha Bashd.salmvnla may be by direct culture, simply Jdakrd Azbafthay with so toxic Drasrspty die chick who could be liver, gallbladder or bacteria directly into the yolk sac removed. In older birds found salmonella in the intestine and cecum more is possible to isolate bacteria. Possible separation from other locations edx such as the ovaries, tubes, egg on, pancreas, joints, testes, heart and eye (6). Salmonella colonization in the intestine but are Plvrvm and Galynarvm easily infect other parts of the bird's body. This helps to stimulate the production of antibodies that can be detected in blood tests. Other serovars of Salmonella colonization in the intestine, but do not invade the tissues of the body easily and thus may provoke antibody production (1). Salmonella isolates were cultured for bacteria-enriched enrichment peptone water is used as a buffer. Selective cerebral three environments that are commonly used include Bgvshhay selenite citrate, tetra Vasylyadys Teun and Rappaport (RV) are (6) with the addition of antibiotics Manndnvvbyvsyn
