Application of a reverse line blot assay to the study of haemoparasites in cattle in Uganda by Oura, C.A.L., Bishop, Richard P., Wampande, E.M., Lubega, G.W., Tait, A.

“…To further this objective, we have evaluated a reverse line blot (RLB) assay, which simultaneously detects the principal tick transmitted protozoan and rickettsial cattle pathogens, in different epidemiological scenarios in Uganda. A critical question is the sensitivity, particularly in relation to detecting carrier animals. …”

Health risk due to exposure to chlorpyrifos for farmers in Thai Binh: Probabilistic risk assessment by Phung Tri Dung, Hung Nguyen-Viet, Tran Thi Tuyet Hanh

“…The research method included three steps: (i) 24-hour urine samples taken from farmers to analyse trichlorpyridinol (TCP), the main metabolite of chlorpyrifos, and then TCP was converted to Absorbed Daily Dose (ADD); (ii) dose-response (RADD) corresponding to acute effects on the nervous system was obtained and recalculated from epidemiologic studies on human population; (iii) the health risk of chlorpyrifos with farmers was evaluated using probabilistic health risk assessment approach with 10,000 trials simulated by Monte Carlo technique. …”

Mapping the global distribution of livestock by Robinson, Timothy P., Wint, G.R.W., Conchedda, Giulia, Boeckel, Thomas P. van, Ercoli, V., Palamara, E., Cinardi, G., D'Aietti, L., Hay, S.I., Gilbert, M.

“…These include analyses of the social and economic aspects of the livestock sector; the environmental impacts of livestock such as the production and management of waste, greenhouse gas emissions and livestock-related land-use change; and large-scale public health and epidemiological investigations. The Gridded Livestock of the World (GLW) database, produced in 2007, provided modelled livestock densities of the world, adjusted to match official (FAOSTAT) national estimates for the reference year 2005, at a spatial resolution of 3 minutes of arc (about 5×5 km at the equator). …”

Re-evaluating the burden of rabies in Africa and Asia by Knobel, D.L., Cleaveland, S., Coleman, P.G., Fèvre, Eric M., Meltzer, M.I., Miranda, M.E.

“…METHODS: Data from these regions were applied to a set of linked epidemiological and economic models. The human population at risk from endemic canine rabies was predicted using data on dog density, and human rabies deaths were estimated using a series of probability steps to determine the likelihood of clinical rabies developing in a person after being bitten by a dog suspected of having rabies. …”

A pilot study of Leptospira in rodents in North-Eastern Kenya by Kimari, M.W.

“…These results demonstrate the need for policy makers to consider disease emergence and transmission in these marginalized parts of Kenya. More epidemiological knowledge of the disease like circulating serotypes and role of animal hosts in the area will greatly aid in forming public health policy aimed at controlling the disease.…”

Molecular detection and phylogenetic analysis of Peste des petits ruminants virus circulating in small ruminants in eastern Amhara region, Ethiopia by Alemu, Biruk G., Gari, Getachew, Libeau, Genevieve, Kwiatek, Olivier, Kidane, Menbere, Belayneh, Rediet, Siraw, Bewuket, Wieland, Barbara, Asfaw, Wondwoson, Abdi, Reta D.

“…Thus, we recommend systematic vaccination to contain outbreaks in affected districts and geographically linked surrounding districts to which the disease could potentially spread due to different epidemiological linkages.…”

Ralstonia Strains from Potato-Growing Regions of Kenya Reveal Two Phylotypes and Epidemic Clonality of Phylotype II Sequevar 1 Strains by Sharma, K., Bocardo, F.I., Abdurahman, A., Briseño, R.I.A., Garrett, K.A., Goss, E.M., Ngundo, G., Kreuze, Jan F., Atieno, E., Munguti, F.M.

“…Studies were conducted to (i) determine the molecular diversity of RSSC strains associated with bacterial wilt of potato in Kenya, (ii) generate an RSSC distribution map for epidemiological inference, and (iii) determine whether phylotype II sequevar 1 strains exhibit epidemic clonality. …”

Enhanced discrimination of African swine fever virus isolates through nucleotide sequencing of the p54, p72, and pB602L (CVR) genes by Gallardo, C., Mwaengo, D.M., Macharia, Joseph M., Arias, Marisa, Taracha, E.A., Soler Garzón, Alvaro, Okoth, S., Martin, E., Kasiti, J., Bishop, Richard P.

“…This highlighted the value of p54 gene sequencing as an additional, intermediate-resolution, molecular epidemiological tool for typing of ASFV viruses. We further evaluated p54-based genotyping, in combination with partial sequences of two other genes, for determining the genetic relationships and origin of viruses responsible for disease outbreaks in Kenya. …”
