Abstract

Economic losses from M. gallisepticum infection resulting from reduced weight gain, feed efficiency, decreased egg production, increased condemnation and medication cost (Yoder 1985) increased the demand for more study about this organism. One of the important steps for combating any disease is to study the properties of the causative organism, its mode of action and its effect on the host which lead to efficient methods of diagnosis, treatment and control (Williams and Nunn, 1978). The biochemistry and the biochemical methods play a very important role in realizing this purpose and that is why the biochemical analysis are considered the first line of defense against the spread of infection within the laboratory (Levine and Becker, 1977). Serum free amino acids of chickens infected with respiratory diseases including Mycoplasma were studied by many authors e.g. Cole and Boyd (1965), Kludas (1968), Squibb and Reed (1969), Wanne Marcher et al. (1972); Blackburn (1978), Ivanov and Doicheva (1979) and Maurice et al., (1983). They concluded that the degree of changes in free amino acids, urea nitro- gen and uric acid characterizes the direction of pathogenic and metabolic process in infected chicks, The aim of this work was to study some biochemical constituents of the serum of chickens infected with M. gallisepticum e.g. urea nitrogen, uric acid and amino acid pattern.
