RESEARCH ON CONTROL OF HEMOPROTOZOAL DISEASES

PROJ WAS INTENDED TO RESEARCH AND DEVELOP CONTROL MEASURES FOR COMBATING HEMOPARASITIC LIVESTOCK DISEASES (ANAPLASMOSIS, BABESIASIS, TRYPANOSOMIOSIS, THEIL ERIOSIS). EVAL WAS CONDUCTED BY VISITING RESEARCH SITES AND EXAMINING THE REVIEWS OF RESEARCH PREPARED BY MEMBERS OF THE TEXAS A &M RESEARCH TEAM. RESRCH WAS SUCCESSFUL IN DEVELOPING AN ANAPLASMOSIS VACCINE,EFFECTIVE PREMUNITION SYSTEMS AGAINST ANAPLASMOSIS & BABESIASIS,IMPROVED DIAGNOSTIC TECHNIQUES INCLUDING A PRACTICAL CARD TEST FOR ANAP & B BIGEMINA,AND NON-BOVINE SOURCES OF BABESIA FROM TICKS & TISSUE CULTURE FOR VACCINES. INVESTIGATIONS WERE CONDUCTED OF NEW & MORE EFFECTIVE CHEMOTHERAPEUTIC AGENTS FOR USE IN PREMUNITION & TREATMENT OF THE DISEASES AND INVESTIGATIONS WERE INITIATED ON THE USE OF NEW IXODICIDES OR THE USE OF MOLASSES GRASS(MELINIS MINUTIFLORA). 17 US & COLOMBIAN GRAD STUDENTS WERE TRAINED TO CONDUCT RESRCH OF THIS TYPE AND ON-THE-JOB TECHNICIAN-LVL TRNG WAS INCORPORATED IN THE PROGRAM. IT IS RECOMMENDED: 1)THE TEXAS A & M(TAM)PROJECT BE EXTENDED TO 6/30/78; 2)PREMUNITION FIELD TRIALS BE COMPLETED AS SCHEDULED UNDER CONTRACT NO TA-C-1220; 3)DETAILED PLANS FOR THESE FIELD TRIALS SHOULD BE REVIEWED BY A CONSULTANT TEAM; 4)LAB TRIALS SHOULD BE CONTINUED WITH THE STABILATE REGARDED AS MOST PROMISING; 5)RAPID CARD TESTS FOR A MARGINALE,B BIGEMINA & B ARGENTINA SHOULD BE PERFECTED; 6)MORE FREQUENT COMMUNICATION SHOULD BE CONDUCTED BETWEEN TAM CONTRACT COORDINATORS & THE FIELD OPERATNS TEAM. WHILE THIS PROJ HAS BEEN SUCCESSFUL IN ADVANCING THE KNOWLEDGE OF & CONTROL OF HEMOPROTOZOAL CATTLE DISEASES IN LATIN AMER,IT IS SUGGESTED THAT RESRCH SHOULD BE EXTENDED TO A GLOBAL SCOPE. ALSO,CENTERS SHOULD BE ESTABLISHED IN LATIN AMER(CIAT) & AFRICA(ICIPE)FOR THE COLLECTION & DISSEMINATION OF LITERATURE ON TICKS AND HEMATOPHAGUS INSECTS. AID SHOULD DEVELOP A SET OF PRINCIPLES & PROCEDURES FOR THE COORDINATION AND PARTITIONING OF FUNDED RESEARCH ON THIS DISEASE PROBLEM.
