Serological Evidence of Rift Valley Fever Virus Circulation in Sheep and Goats in Zambézia Province, Mozambique

In this study, Rift Valley Fever Virus (RVFV) infection was searched serologically and pathologically in cattle (178 Holstein), sheep (160 native), goats (66 ordinary goats, 98 Honamli goats, 16 Saanen goats) with an abortion history and in unborn cattle (8), sheep (24) and goat (5) fetus. Samples were collected between July 2009 and September 2010. As a result of studying specific antibodies to RVFV by using the c-ELISA method in blood serum samples collected from cattle, sheep and goats suffering abortion, seropositivity was identified in 7 cattle (7/178; 3.93%), 4 sheep (4/160;2.50%) and 18 goats (18/180;10.0%). 18 seropositive goats were distributed according to race as 13 ordinary goats (19.70%), 2 Honamli goats (2.04%) and 3 Saanen goats (18.75%). When liver, spleen and brain samples of the unborn fetus of cattle, sheep and goats were studied histopathologically, no pathological findings on RVFV disease were obtained. Consequently, in this study, where RVFV infection in cattle, sheep and goats raised in Western Mediterranean Region of Turkey was serologically revealed, it was concluded that RVFV did not take place in the aetiology of abortion cases in relevant species.

Rift Valley fever virus (RVFV) is an acute, zoonotic viral disease caused by a Phlebovirus, which belongs to the Bunyaviridae family. Among livestock, outbreaks of the disease are economically devastating. They are often characterised by large, sweeping abortion storms and have significant mortality in adult livestock. The aim of the current study was to investigate RVFV infection in the Kigoma region, which is nestled under the hills of the western arm of the Great Rift Valley on the edge of Lake Tanganyika, Tanzania. A region-wide serosurvey was conducted on non-vaccinated small ruminants (sheep and goats, n = 411). Sera samples were tested for the presence of anti-RVFV antibodies and viral antigen, using commercial enzyme-linked immunosorbent assay and reverse transcriptase polymerase chain reaction, respectively. The overall past infections were detected in 22 of the 411 animals, 5.4% (Confidence Interval (CI) 95% = 3.5% – 8.1%). The Kigoma rural area recorded the higher seroprevalence of 12.0% (CI 95% = 7.3% – 18.3%; p < 0.0001), followed by Kibondo at 2.3% (CI 95% = 0.5% – 6.5%; p > 0.05) and the Kasulu district at 0.8% (CI 95% = 0.0% – 4.2%; p > 0.05). The prevalence was 12.5% and 4.7% for sheep and goats, respectively. Reverse transcriptase polymerase chain reaction results indicated that only eight samples were found to be positive (n = 63). This study has confirmed, for the first time, the presence of the RVFV in the Kigoma region four years after the 2007 epizootic in Tanzania. The study further suggests that the virus activity exists during the inter-epizootic period, even in regions with no history of RVFV.
