Genetic diversity among isolates of Trichinella spiralis from the Province of Buenos Aires, Argentina 总被引:8,自引:0,他引:8
Random Amplified Polymorphic DNAs, (RAPDs) are used to study the occurrence of Trichinella britovi and T5 among domestic animals in the Province of Buenos Aires, Argentina and to assess the genetic diversity among isolates of T. spiralisfrom this area in a number of infected hosts. All the local isolates proved to be T. spiralis. Six of the eight primers used indicate that the Buenos Aires isolates are distinct from each other as they produce a considerable number of polymorphic bands. Our overall estimates are relatively higher than other intraspecific distances previously estimated within species of this genus and among T. spiralis isolates. Such high degrees of variability observed among local isolates and between isolates from Buenos Aires and Spain should be taken into account when defining isolates within this species, and considering differences in the epidemiology of T. spiralis. 相似文献

We cloned and characterized a Plasmodium vivax repeat element of 7872bp named PvRE7.8. Several internal tandem repeats were found along the sequence. The repetitive nature of the PvRE7.8 element was confirmed by hybridization of a P. vivax YAC library. Based on the data bank analysis and the presence of two contiguous putative genes that may encode proteins related to DNA metabolism, PvRE7.8 could be considered an inactivated transposon-LINE element. By using Pv79 as probe or primers derived from Pv79-flanking sequences, P. vivax DNA Could be detected from whole blood and mosquito samples. We consider that the repeat element described here has potential for P. vivax malaria diagnosis and for epidemiological analysis of P. vivax transmission areas. 相似文献

A novel tandemly repeated DNA structure of Toxoplasma gondii that meets the requirements assigned for satellital DNA was characterized. A DNA fragment of 1002 bp contains two different elements of repetitive DNA families named ABGTg7 and ABGTg8.2. Both repeats are members of a more complex tandem structure where ABGTg7-like monomers can be arranged either as direct tandems or flanked by other related or non-related repeats. Pulse-field gel electrophoresis analysis showed that these repeats hybridize with the largest T. gondii chromosomes. Bal31 sensitivity assays indicated that these elements are located near the telomeres and along other regions too. Five genomic lambda phages were isolated and two different completed clusters of the repeated structure were analyzed. 相似文献

A retrospective survey of hospital cases to obtain baseline data on hydatid disease in the northwest of the Province of Chubut, Argentina, from 1973 to 1979 revealed annual mean rates that varied between 13.4 and 75.8 confirmed new cases per 100.000 population. Inclusion of data on parasitologically confirmed non-surgical cases and on the geographic origin of patients permitted a more accurate estimate of cases in the four Departments comprised in the study area. Information on cyst location, clinical status at admission, mortality, number of re-operations and length of hospitalization was obtained to assess the public health impact of hydatidosis within the area. The criteria established and methods used to collect this information are described and discussed. 相似文献
