Since 1980 plague has been a human threat in the Western Usambara Mountains in Tanzania. However, the spatial-temporal pattern of plague occurrence remains poorly understood. The main objective of this study was to gain understanding of human activity patterns in relation to spatial distribution of fleas in Lushoto District. Data were collected in three landscapes differing in plague incidence....
Introduction: Biological attacks are a phenomenon that started on a serious note in the twentieth century and such weapons are being developed every day.The agent of plague is one of those listed as biological weapons by the Weapons Convention. So, the danger of its biological or bioterrorist applications by the enemy is possible and poses a serious threat. The purpose of compiling this article...
Thirteen pine martens (Martes americana) were sampled periodically from July 1979 to September 1980 for plague (Yersinia pestis) antibodies and their fleas collected and identified. Four individuals were positive for plague antibodies on 8 of 24 sampling occasions. Titer peaks in these individuals occurred simultaneously in early winter but fell to undetectable levels by late spring. A chipmunk...
"Plague added the finishing touches to the great misery of Bristol; its inhabitants resembled prisoners more than citizens, being so low with taxation, so poor in habit, and so dejected in countenance." (Skeete 1645, quoted Latimer) En^6,? hundred years ago the final and most dramatic epidemic of the plague struck ann andJ an^ t^le terrible visitation at Marseilles in 1720, epidemic plague disB...
ever, experience suggested that these measures in the field were able to achieve only a partial control of plague infection which continued to reappear in such village during the favourable plague season. The use of D.D.T. seems to have changed this state of affairs as observed from the recent field experience in various districts of the province. With a view to finding out the most effective m...
Plague, a zoonotic disease caused by the bacterium Yersinia pestis, has been responsible for at least 3 pandemics. During 1582-1583, a plague outbreak devastated the seaport of Alghero in Sardinia. By analyzing contemporary medical texts and local documentation, we uncovered the pivotal role played by the Protomedicus of Alghero, Quinto Tiberio Angelerio (1532-1617), in controlling the epidemic...
background : tropical rat mite ( ornithonyssus bacoti ) is reported from many parts of the world and is considered important in transmitting rickettsial pathogens. there have been scanty reports on prevalence of this parasite from india. following a recent report of o. bacoti infestation in a laboratory mice colony from nilgiris, tamil nadu, india, attempts were made to detect the parasite in ...
There are eight essays and an introduction in this excellent monograph. It is concerned particularly with the demographic effects of plague and is aimed at the historian and general reader. General issues are dealt with in articles on 'Some medical aspects of plague' (Leslie Bradley), 'Current medical and epidemiological views on plague' (J. N. Biraben), 'Plague in Britain' (Christopher Morris)...
Chemical decomposition and fragmentation may limit the detection of ancient host and microbial DNA while some proteins can be detected for extended periods of time. We applied paleoproteomics on 300-year-old dental pulp specimens recovered from 16 individuals in two archeological funeral sites in France, comprising one documented plague site and one documented plague-negative site. The dental p...
The bacteria Yersinia pestis is the etiological agent of plague and has caused human pandemics with millions of deaths in historic times. How and when it originated remains contentious. Here, we report the oldest direct evidence of Yersinia pestis identified by ancient DNA in human teeth from Asia and Europe dating from 2,800 to 5,000 years ago. By sequencing the genomes, we find that these anc...
