African swine fever (ASF) is an acute, highly infectious and fatal arboviral disease affecting both wild and domestic pigs causing a very high mortality rate that goes up to 100%. Up to date no vaccines are available to protect the animals against the disease. No study has been conducted to assess the presence of ASFV in imported slaughtered pigs in Bukavu city and very limited literature is available on ASF in the entire country of Democratic Republic of Congo. A cross sectional study was carried out in Muhanzi municipal abattoir of Bukavu city, eastern Democratic Republic of Congo to investigate the presence of antibodies against African swine fever virus (ASFV) and the viral genome in imported pigs for slaughtering. The commercial enzyme-linked immunosorbent and the conventional polymerase chain reaction assays were used to screen both ASFV antibodies and viral genome respectively. In total 284 pigs were tested out of which 87.3% (248/284) were female adult of more than 1 year old. The majority of them (75.4% (214/284) were imported from Rwanda of which about 62.7% (178/284) of them presented clinical sign such as redness in the skin. Most of them (90.8%) were exotic breed. Out of 284 animals tested, ASFV antibodies were detected in 69 giving an overall seroprevalence of 24.2% from which pigs originated from Idjwi territory were more ASF seropositive (64.2%) compared to the one imported from Rwanda (11.2%). The seropositivity was found to be significantly associated with the breed (OR= 7.4, p 0.05). Additionally, 38 animals out of 284 tested (13.3%) were ASFV PCR positive with high infectivity rate (35.7%) when pigs slaughtered originated from Idjwi territory of the DRC were found to be more infected than the one imported from Rwanda (OR= 8.5, p |
