[Molecular epidemiological characterization of rabies virus isolated from Guangxi].

Background: To analyze the genotype of rabies virus isolated from different areas in Guangxi at different time.

Methods: mRNA of 8 Guangxi isolates, 1 Anhui isolates and 10 isolates from different countries of rabies virus were amplified by reverse transcription polymerse chain reaction (TR-PCR),and the products were sequenced. Phylogenetic analysis was carried out by phylip program.

From research to "best practices" in other settings and populations.

Objective: To review the genesis and current status of best practices" thinking, its application in health promotion practice, and in generalizing research to alternate populations, places and times.

Methods: A presbyopic eye is cast over the recent evolution of the concept of "best practices" from medicine to public health.

Results: Some discontinuities are found in the migration of this concept from medicine, where it applies with some consistency to the relatively homogeneous physiology of the human species, to health behaviorwhere social, cultural, economic, and other heterogeneities make the generalizability of any research more suspect.

A family of pupal-specific cuticular protein genes in the mosquito Anopheles gambiae.

We have cloned and sequenced members of a cuticular protein multi-gene family from the mosquito Anopheles gambiae. Three genes (agcp2a-c), each approximately 1 kb in length, were found in a 17.4 kb genomic phage clone.

Trends in human immunodeficiency virus seroprevalence among injection drug users entering drug treatment centers, United States, 1988-1993.

National unlinked sentinel surveillance data were used to describe trends in prevalent human immunodeficiency virus infection among injection drug users entering drug treatment programs in the United States from 1988 through 1993. During this 6-year period, unlinked testing was performed on 70,882 specimens from injection drug users at 60 sentinel sites. The annual change in seroprevalence was estimated for each site by odds ratios obtained from logistic regression models fit within site-specific age and race/ethnicity subgroups.
