Article Synopsis
- * Research combined chromosomal, microsatellite, and ecological data to uncover genetic variations among the different forms of Anopheles gambiae, finding that the Forest M form is distinct from both the Mopti-M form and the S form.
- * The Forest M form shows a strong preference for wetter environments and has several chromosomal inversions, suggesting its unique genetic identity; however, potential gene flow between this and the Mopti-M form exists, which could affect studies on traits like insecticide resistance.
This study was designed to identify changes in parasite-specific immune responses that occur during vertical transmission of Neospora caninum and can be used as indicators of parasite reactivation in naturally infected heifers. Ten heifers were unimmunized and 11 immunized with killed tachyzoites. One unimmunized heifer, which aborted at week 19 of gestation, had an increase in parasite-specific antibodies, mainly IgG(2), from week 15 to week 19 and a concomitant decline in parasite-specific cell-mediated immune (CMI) responses.

The parasite is spread efficiently from mother to foetus over several generations, and naturally infected cattle do not appear to develop adequate protective immunity. Modulation of the immune response during pregnancy favours parasite survival and multiplication.
