Abstract A retrospective serosurvey of multi-host feline and canine viruses among carnivore species in southern Africa (n = 1018) identified widespread pathogen exposure even in remote protected areas. In contrast to morality experienced in East African predators, canine distemper virus (CDV) infection among African wild dogs (Lycaon pictus) in Botswana was not associated with identifiable change in pup survivorship or disease related mortality of adults. A disease outbreak of unknown aetiology occurred in the same population over 4 weeks in 1996. Outbreak boundaries coincided with ecotones, not the spatial distribution of contiguous packs, highlighting the potential importance of landscape heterogeneities in these processes. Direct management of pathogens in domestic animal reservoirs is complicated by the apparent complexity of pathogen maintenance and transmission in these large systems. Conservation effort should be focused at securing large metapopulations able to compensate for expected episodic generalist pathogen invasion and attention directed to addressing underlying causes of population depression such as habitat loss and wildlife conflict.

Background: Little is known about long-term pediatric health outcomes following influenza vaccination during pregnancy. Objectives: The objectives of this study were to assess the associations between prenatal exposure to maternal pandemic H1N1 (pH1N1) influenza vaccination and pH1N1 illness, with long-term immune-related pediatric health outcomes. Methods: This retrospective cohort study used a province-wide birth registry from Ontario, individually linked with health administrative databases to ascertain study outcomes over five years of follow-up. Results: We found a weak, but statistically significant, increased association between prenatal pH1N1 influenza vaccination and pediatric asthma, and an inverse association with gastrointestinal infections; otherwise, no other significant associations were observed. Conversely, significant increased associations were observed between pH1N1 influenza illness during pregnancy and all study outcomes. Conclusions: The findings of this study support the safety of influenza vaccination during pregnancy; however more research in this area is required, particularly for seasonal influenza vaccine.

4 pp. / Vaccinating for clostridial diseases is an important part of a ranch health program. These infections can have significant economic impacts on the ranch due to animal losses. There are several diseases caused by different organisms from the genus Clostridia, and most of these are preventable with a sound vaccination program. Many of these infections can progress very rapidly; animals that were healthy yesterday are simply found dead with no observed signs of sickness. In most cases treatment is difficult or impossible, therefore we rely on vaccination to prevent infection. The most common organisms included in a 7-way or 8-way clostridial vaccine are discussed below. By understanding how these diseases occur, how quickly they can progress, and which animals are at risk you will have a chance to improve your herd health and prevent the potential economic losses that come with a clostridial disease outbreak.

Mise en contexte : La vaccination est l’une des interventions de santé publique les plus efficaces. Malgré son progrès notable, l’OMS affirme que 16000 enfants de moins de 5 ans meurent encore chaque jour. Les connaissances, croyances et attitudes des parents face à la vaccination peuvent être influencées par les connaissances et attitudes des professionnels de la santé. L’impact de l’éducation des professionnels, même si elle consiste en une session unique, a un effet notable dans le domaine de la santé des familles. Des infirmières en milieu de soins tertiaires et qui sont en contact avec les familles doivent être bien informées afin de guider les parents dans leurs décisions face à la vaccination de leur enfant. Méthodologie : Une analyse des croyances des infirmières sur la vaccination infantile a précédé une étude descriptive comparative avec devis pré et post-test afin de mesurer les connaissances et attitudes des infirmières sur la vaccination infantile avant et après une courte session éducative par PowerPoint. Le modèle d’apprentissage de Gagné a été utilisé pour bâtir le plan d’enseignement de cette session d’éducation. Des analyses de type descriptif et inférentiel ont été utilisées afin de comparer ces variables chez des infirmières de pédiatrie et de chirurgie générale. Résultats : Les analyses ont démontré une augmentation significative des connaissances des infirmières suite à la session éducative ainsi qu’un changement minime de leurs attitudes. Il n’y avait pas de différence significative entre les infirmières de pédiatrie et de chirurgie. Conclusion : Cette étude a démontré l’importance d’une formation continue en milieu tertiaire concernant la vaccination infantile. Des implications et recommandations pour l’éducation, la pratique et la recherche ont été formulées afin de promouvoir des pratiques de soins adaptées aux besoins de santé des familles.
