RESUMEN
Screw-worms (Cochliomyia hominivorax Coquerel) constitute a serious plight for livestock in the New World, because they inflict high losses on animals and man. A survey was done by means of an epizootic surveillance system with geographic squares to check for the presence of the insects in Cuba. Screw-worms were detected in 54.8% of myiasis cases all over the island, affecting various animals species, cattle first, followed by swine, sheep and others. Small injuries appeared to be the main enabling factor for screw-worm development. The reasons for the presence of screw-worms without serious consequences on the Cuban livestock are discussed.

An immunoperoxidase assay for the serological diagnosis of Babesia bigemina was developed. The antigen slides were prepared from B. bigemina-infected blood and stored at -20 degrees C. One hundred and sixty five sera were tested, comparing the immunoperoxidase assay to the indirect fluorescent antibody test. A coincidence of 95% was observed between both tests. For the immunoperoxidase assay, a relative sensitivity of 94.8%, a relative specificity of 95.5%, and a positive predictive value of 96.8% were calculated. The results demonstrated the efficacy of this technique for detecting antibodies to B. bigemina.
