| co-circulation of multiple genotypes of african swine fever viruses among domestic pigs in zambia (2013-2015). | during 2013-2015, several and severe outbreaks of african swine fever (asf) affected domestic pigs in six provinces of zambia. genetic characterization of asf viruses (asfvs) using standardized genotyping procedures revealed that genotypes i, ii and xiv were associated with these outbreaks. molecular and epidemiological data suggest that genotype ii asfv (georgia 2007/1-like) detected in northern province of zambia may have been introduced from neighbouring tanzania. also, a genotype ii virus de ... | 2017 | 28299893 |
| molecular, serological and epidemiological observations after a suspected outbreak of plague in nyimba, eastern zambia. | plague is a re-emerging zoonotic disease caused by the bacterium yersinia pestis. the disease has caused periodic global devastation since the first outbreak in the 6th century. two months after a suspected plague outbreak in nyimba district, samples were collected from 94 livestock (goats and pigs), 25 rodents, 6 shrews and 33 fleas. enzyme-linked immunosorbent assay (elisa) and polymerase chain reaction (pcr) techniques were used to investigate the presence of y. pestis, which showed that 16.0 ... | 2017 | 27578859 |
| potential roles of pigs, small ruminants, rodents, and their flea vectors in plague epidemiology in sinda district, eastern zambia. | a cross-sectional study was conducted in the eastern part of zambia that previously reported a plague outbreak. the aim of the study was to evaluate the potential role of pigs, goats, and sheep as sero-surveillance hosts for monitoring plague, and to investigate the flea vectors and potential reservoir hosts to establish the current status of plague endemicity in the district. serum samples were collected from 96 rodents, 10 shrews, 245 domestic pigs, 232 goats, and 31 sheep, whereas 106 organs ... | 2017 | 28399281 |
| the epidemiology of african swine fever in "nonendemic" regions of zambia (1989-2015): implications for disease prevention and control. | african swine fever (asf) is a highly contagious and deadly viral hemorrhagic disease of swine. in zambia, asf was first reported in 1912 in eastern province and is currently believed to be endemic in that province only. strict quarantine measures implemented at the luangwa river bridge, the only surface outlet from eastern province, appeared to be successful in restricting the disease. however, in 1989, an outbreak occurred for the first time outside the endemic province. sporadic outbreaks hav ... | 2017 | 28832525 |
