The 2012 RUFORUM Biennial Conference is the third in the series. The main objective of the Biennial conferences is to provide a platform for agricultural research for development stakeholders in Africa and beyond to actively exchange findings and experiences, while at the same time learning lessons towards improving performance of the agricultural sector and ultimately people’s livelihoods. The biennial conference is RUFORUM’s most comprehensive meeting for the diversity of stakeholers in agriculture. It is especially dedicated to graduate students and their supervisors, grantees in RUFORUM member universities and alumni. It is a platform for peer review, quality control, mentorship, networking and shared learning. The third Biennial Conference was attended by 657 participants. This record contains an extended abstract accepted under the theme of Enhancing Livestock Productivity.
Peste Des Petits Ruminants (PPR) Outbreak in Southern, Tanzania
Abstract:
Peste des petits ruminants (PPR) was first confirmed in
Tanzania in 2008, however description of clinical or pathological
signs was not carried out although this is important to assist
quick identification and reporting of PPR cases by both livestock
keepers and field-based animal health workers. A study was
therefore conducted to investigate and describe clinical signs
and pathological lesions associated with suspected PPR cases
in southern Tanzania. It involved history taking and clinical
examination of suspected cases of 25 goats and 3 sheep. Postmortem examination of some cases was performed followed by collection of specimens for histopathological examination. Swabs were also collected for confirmation of PPR by detecting ribonucleic acid using reverse transcription polymerase chain reaction (RT-PCR). Serum samples were analysed using competitive enzyme linked immunosorbent assay (cELISA).
Severe depression, high fever, anorexia, muco-pulurent nasal
discharge, erosive and necrotic stomatitis, mild diarrhoea and
skin nodules were major signs suggestive of PPR. Post mortem examination showed evidence of pneumonia including lung congestion and consolidation. RT-PCR confirmed presence of the PPR virus in samples and serum antibodies showed seroprevalence of 31%.
La Peste des petits ruminants (PPR) a été confirmée pour la
première fois en Tanzanie en 2008, mais la description de signes
cliniques ou pathologiques n’a pas été effectuée, bien que ceci
soit important pour faciliter l’identification rapide et la notification
des cas de PPR par les éleveurs et les agents de santé animale
basés sur terrain . Une étude a donc été menée afin de
rechercher et de décrire les signes cliniques et les lésions
pathologiques associées à des cas présumés de PPR au sud de
la Tanzanie. Elle a impliqué l’anamnèse et l’examen clinique
des cas suspects de 25 chèvres et 3 moutons. L’examen postmortem
de certains cas a été effectué, suivi par la collecte
d’échantillons pour l’examen histopathologique. Les échantillons
ont été prélevés pour la confirmation de la PPR en détectant
l’acide ribonucléique en utilisant la transcription inverse de la
réaction en chaîne de la polymérase (RT-PCR). Des échantillons
de sérum ont été analysés en utilisant l’enzyme concurrentiel
lié à l’essai immunoabsorbant (cELISA). La dépression sévère,
une forte fièvre, l’anorexie, l’écoulement nasal muco-pulurent,
la stomatite érosive et nécrotique, la diarrhée légère et les
nodules cutanés étaient les principaux signes évocateurs de la
PPR. L’autopsie a montré des signes de pneumonie, incluant la
congestion et la consolidation des poumons. La RT-PCR a
confirmé la présence du virus de la PPR dans les échantillons
et les anticorps sériques ont montré la séroprévalence de 31%.
