Abstract
The protein Consider one of the nutrient elements that has important role in the metabolism of organism body , its decrease in food causes less weight body and more changes of tissues. therefore , this study conducted to know the protein deficiency effect of two types of chickens .30 chicks (15 Hubbard+ 15Ross) on day old ,divided to three groups ,every groups contain 10 chicks (5 Hubbard+5Ross) as follow: first group is control (were given 23% crude protein including ) ,2nd group (were given 20.5% crude protein including ) , the 3rd group were given 18% crude protein. Studied the change of bodies weights and histological change of liver .result showed significant decrease (p >0.05)in 2nd and 3rd groups (of both types) comparative with control groups . On histological examination of liver it revealed in 3rd group 18% CP include dilation in central vein and erode to its epithelium , congestion in hepatic sinusoids with apoptosis and erode to the general structure of liver , while 2nd group 20.5% CP appeared less effect like some congestion in central vein , small dilation in the sinusoids with necrosis in some of cells. 40Cº the phage activity was not affected but it was decreased continuously when temperature increase 50 Cº and 60 Cº, in 70 Cº phage activity was diminished in about 7-8 minutes. Highest adsorption rate of isolated vibriophages on bacterial cells was about 2-4 minutes, time increment significantly increase the adsorption while dilution and shaking reduce adsorption. Maximum lysis activity of bacterial cells was documented in about two hours and resulted in elevation of viral concentration and decreasing bacterial cell concentration in the same time, complete lysis time was about 6 hours. Results also showed that the sensitivity of isolated bacteria towards the phages was high especially to river phages about 88.5% and less to sewage phages 77.22%, while highest sensitivity was recorded in the positive reference strain 91%.Over all results of this work reflect the important role of vibriophages in controlling the levels of Vibrio cholerae in environment.
