Studies on Some Possible Poultry Diseases Which Can Be Transmitted Through Imported Flocks

This study was carried out to investigate the pre- velance of bacterial, viral and mycotic agents among im- prted fertile eggs and one day-old chicks. The patho-geni~ity of a representative isolates to one day-old chicks were also investigated. The following results are1. The the bacteriologically examined 1000 fertile eggs in a rateof 4 percent. These isolates are identified into 14 E.coliserologically related to 7 serogroups, 7Pseudomonas aeru- ginosa/8 Proteus and 11 Citrobacter in isolation rates of1.4, 0.7,0.8 and 1.1 percent, respectively as well as 2 Aspergillus flavous isolates in a rate of 0.2 percent.examined 400 day-old chicks in a rate of 5 percent, whichidentified into 6 Salmonella gallinarum pullorum, 8 E. coli related to 4 serogroups and 6 Citrobacter in isola-tion rates 1.5, 2 and 1.5 percent; respectively.3. The virological examination of 175 fertile eggs pointed out the isolation and seroidentification of3 isolates of Newcastle disease virus , 3 isolates of adeno virus (related to Celo virus) and 1 strain related toReovirus in rates of 1.71, 1.71 and 0.57 percent, respect- ively.
