Antibiotic prophylaxis in veterinary cancer chemotherapy: a review and recommendations.

Bacterial infection following cancer chemotherapy-induced neutropenia is a serious cause of morbidity and mortality in human and veterinary patients. Antimicrobial prophylaxis is contro-versial in the human oncology field, as any decreased incidence in bacterial infections is countered by patient adverse effects and increased antimicrobial resistance. Comprehensiveguidelines exist to aid human oncologists in prescribing antimicrobial prophylaxis but similar recommendations are not available in veterinary literature. As the veterinarian's role in antimi-crobial stewardship is increasingly emphasized, it is vital that veterinary oncologists implement appropriate antimicrobial use. By considering the available human and veterinary literature wepresent an overview of current clinical practices and are able to suggest recommendations for prophylactic antimicrobial use in veterinary cancer chemotherapy patients.<br/

Genetic Diversity and Population Structure of Acacia senegal (L) Willd. in Kenya

The level of genetic diversity and population structure of Acacia senegal variety kerensis in Kenya was examined using seven polymorphic nuclear microsatellite loci and two chloroplast microsatellite loci. In both chloroplast and nuclear datasets, high levels of genetic diversity were found within all populations and genetic differentiation among populations was low, indicating extensive gene flow. Analysis of population structure provided support for the presence of two groups of populations, although all individuals had mixed ancestry. Groups reflected the influence of geography on gene flow, with one representing Rift Valley populations whilst the other represented populations from Eastern Kenya. The similarities between estimates derived from nuclear and chloroplast data suggest highly effective gene dispersal by both pollen and seed in this species, although population structure appears to have been influenced by distributional changes in the past. The few contrasts between the spatial patterns for nuclear and chloroplast data provided additional support for the idea that, having fragmented in the past, groups are now thoroughly mixed as a result of extensive gene flow. For the purposes of conservation and in situ management of genetic resources, sampling could target a few, large populations ideally distributed among the spatial groups identified. This should ensure the majority of extant variation is preserved, and facilitate the investigation of variation in important phenotypic traits and development of breeding populations

The current situation and prospects for gum arabic in Kenya: A promising sector for pastoralists living in arid lands

Gum arabic, a natural exudate produced by Acacia senegal trees, is available in abundance in Kenya, mainly in the northern part of the country, but its exploitation is marginal. This study, conducted among harvesters, traders and other actors involved in the development and business of the gum arabic industry in Kenya has shown and confirmed the results of other researches, that the supply chain is currently under-developed. Harvesters do not collect sufficient quantities of gum arabic because they are not linked to buyers, and when they are the low prices they receive discourage them from developing that income generating activity. Pastoralists currently only collect gum when they see it, and do not use modern harvesting techniques. They stand to benefit from that activity if they are more organized and if that business was more developed in the country. Recognizing the unmet international demand for gum arabic and the largely untapped reserves growing in the wild and in abundance in the northern part of the country suggests that improvements can be made to harvesting and marketing. Through training, with specific attention to quality issues and international requirements, the constitution of stocks in collection areas and the development of direct links with traders, Kenya can penetrate the international market of gum arabic and improve its market share. Various activities have been undertaken and have already shown good results. (Résumé d'auteur
