INTRODUCTION HEMATOLOGICAL responses to Mycoplasma gallisepticum (S6 strain) under normal temperature conditions have been studied by Fedde (1964) and Fedde and Pomeroy (1967). They found that there was a consistent monocytosis, which started as early as the second day post-inoculation and reached a maximum around the tenth day. There was an increase in the total number of white blood cells, total serum proteins, and the absolute number of heterophils, while the Arneth index was decreased. The infectious sinusitis caused by this microorganism is most prevalent in early fall when there is considerable variation in weather conditions and the temperature starts decreasing. This study was designed to determine the response of various blood components in M. gallisepticum inoculated and uninoculated turkeys in a cold environment. MATERIALS AND METHODS Thirteen male and fifteen female Broad White turkeys, five weeks old, were randomly divided at the start of the experiment into three replicate … |
