RESOLAB Annual Coordination Meeting - fao ectad bamako

should be charged to be responsible for this but should share idea with thelab personnel.Isolation of novel genotype 7 with 4 sublineages was reported to becirculating in backyard poultry of West and Central Africa by Dr. Cattoli.Virus isolation was discovered to be more sensitive for the detection of thisgenotype compared to real time RT-PCR due to mutation in the HN and Fgene. The real time RT-PCR assay protocol has thus been modified to detectall genotypes.Newcastle Disease Virus vaccine failure was identified as serious problem inpoultry production system by member states. The RESOLAB was urged tocome up with modalities to address this problem in conjunction with NDVvaccine producing member countries, PANVAC and reference laboratory tofind solution based on the report of the new genotype.It was observed that the quality of the NDV vaccines used in the field insome instances may be okay but the storage, transport and wrongadministration could be responsible for some purported failure of thevaccine on the field.Based on the report of the circulation of new genotype NDV, membercountries were urged to intensify surveillance at country and network levelto identify other circulating genotype (if any) in the sub region.Use of Haemagglutination-Inhibition (HI) test for ND diagnosis as stated insome member countries presentation was brought to fore. It was clarifiedthat use of such diagnostic technique for confirmation especially for serasamples is not satisfactory. It was also mentioned that HI can not be used todistinguish between virulent and non-virulent strains of NDV. Membercountries should therefore take note.It was mentioned that USDA-APHIS has a NDV vaccination project in thepipeline for Africa countries.RESOLAB Member countries were encouraged to use the training acquiredfrom AI projects to consolidate on addressing other poultry diseases egGumboro disease, etcThe lesson learnt from the QA workshops held in Dakar and Douala for the18 RESOLAB French speaking countries and Accra for the 5 RESOLAB Englishspeaking countries emphasized the need to be steadfast on their qualitymanagement system (QMS) implementation pursuit as there is still more8
