Microbial Isolates from Mastitic Udders Following Chemotherapy Failure

Abstract

In order to determine the range of micro­ organisms responsible for non-responsive mastitis, a total of 42 milk samples were collected from dairy animals in Morogoro and Dar es Salaam. Samples were then transported in cool boxes to the laboratory for cultures for aerobic bacteria, fungi and yeast. A portion of each sample was kept frozen until cultured for Mycobacterium species. Four isolates from milk were identified as Mycobacterium (M) species. These included M. bovis (1), M. jlavescens (1) and M. terrae (2). The latter two are environmental micro­ organisms of little public health importance. Of major public health significance is the isolation- of M. bovis, albeit from one animal.
