Genetic characterization of new West African simian immunodeficiency virus SIVsm: geographic clustering of household-derived SIV strains with human immunodeficiency virus type 2 subtypes and
It has been proposed that human immunodeficiency virus type 2 (HIV-2) originated from simian immunodeficiency viruses (SIVs) that are natural infections of sooty mangabeys (Cercocebus torquatusExpand

Human immunodeficiency virus type 2 (HIV-2) seroprevalence and characterization of a distinct HIV-2 genetic subtype from the natural range of simian immunodeficiency virus-infected sooty mangabeys.
The extent of zoonotic infections in rural Sierra Leone, where both feral and pet sooty mangabeys harbor divergent members of the human immunodeficiency virus type 2 (HIV-2)-sooty mangabey simianExpand

Teichoic acids are temporal and spatial regulators of peptidoglycan cross-linking in Staphylococcus aureus
The cell wall of Staphylococcus aureus is characterized by an extremely high degree of cross-linking within its peptidoglycan (PGN). Penicillin-binding protein 4 (PBP4) is required for the synthesisExpand

Island Biogeography Reveals the Deep History of SIV
Separation of the island of Bioko from West Africa about 10,000 years ago dates the origins of simian immunodeficiency virus. Simian immunodeficiency virus (SIV) lineages have been identified thatExpand

Detection and Partial Characterization of Simian Immunodeficiency Virus SIVsm Strains from Bush Meat Samples from Rural Sierra Leone
ABSTRACT Human immunodeficiency virus type 2 (HIV-2) originated from simian immunodeficiency viruses (SIVs) that naturally infect sooty mangabeys (SMs; Cercocebus atys). In order to furtherExpand

Correction for Wittmann et al., Isolates of Zaire ebolavirus from wild apes reveal genetic lineage and recombinants
Over the last 30 years, Zaire ebolavirus (ZEBOV), a virus highly pathogenic for humans and wild apes, has emerged repeatedly in Central Africa. Thus far, only a few virus isolates have beenExpand

A link between SIVsm in sooty mangabeys (SM) in wild-living monkeys in Sierra Leone and SIVsm in an American-based SM colony.
We have developed a noninvasive method for SIVsm virion RNA detection in feces of captive sooty mangabeys (SMs) (Cercocebus atys). Employing this method to investigate the natural history of SIVsm inExpand

Monofunctional transglycosylases are not essential for Staphylococcus aureus cell wall synthesis.
The polymerization of peptidoglycan is the result of two types of enzymatic activities: transglycosylation, the formation of linear glycan chains, and transpeptidation, the formation of peptideExpand

Functional similarities between phage lambda Orf and Escherichia coli RecFOR in initiation of genetic exchange.
Genetic recombination in bacteriophage lambda relies on DNA end processing by Exo to expose 3'-tailed strands for annealing and exchange by beta protein. Phage lambda encodes an additionalExpand
