Validation and Identification of Invasive Salmonella Serotypes in Sub-Saharan Africa by Multiplex Polymerase Chain Reaction.
(Clin Infect Dis, 2016-03-15)
Salmonella enterica serovar Typhi and nontyphoidal Salmonella (NTS) cause the majority
of bloodstream infections in sub-Saharan Africa; however, serotyping is rarely performed.
We validated a multiplex polymerase chain reaction ...
Detection of Bartonella species in the blood of veterinarians and veterinary technicians: a newly recognized occupational hazard?
(Vector Borne Zoonotic Dis, 2014-08)
BACKGROUND: Bartonella species are important emerging pathogens in human and veterinary
medicine. In the context of their daily activities, veterinary professionals have
frequent animal contact and arthropod exposures. Detection ...
Association of HIV-1 Envelope-Specific Breast Milk IgA Responses with Reduced Risk of Postnatal Mother-to-Child Transmission of HIV-1.
(J Virol, 2015-10)
UNLABELLED: Infants born to HIV-1-infected mothers in resource-limited areas where
replacement feeding is unsafe and impractical are repeatedly exposed to HIV-1 throughout
breastfeeding. Despite this, the majority of infants ...
The human antibody response to the surface of Mycobacterium tuberculosis.
(PLoS One, 2014)
BACKGROUND: Vaccine-induced human antibodies to surface components of Haemophilus
influenzae and Streptococcus pneumonia are correlated with protection. Monoclonal
antibodies to surface components of Mycobacterium tuberculosis ...
A randomized controlled trial of standard versus intensified tuberculosis diagnostics on treatment decisions by physicians in Northern Tanzania.
(BMC Infect Dis, 2014-02-20)
BACKGROUND: Routine tuberculosis culture remains unavailable in many high-burden areas,

culture results over standard of care ...
IGHV1-69 B cell chronic lymphocytic leukemia antibodies cross-react with HIV-1 and hepatitis C virus antigens as well as intestinal commensal bacteria.
(PLoS One, 2014)
B-cell chronic lymphocytic leukemia (B-CLL) patients expressing unmutated immunoglobulin

BACKGROUND: Q fever is a common cause of febrile illness and community-acquired pneumonia
in resource-limited settings. Coxiella burnetii, the causative pathogen, is transmitted
among varied host species, but the epidemiology ...
Preexisting compensatory amino acids compromise fitness costs of a HIV-1 T cell escape mutation.
(Retrovirology, 2014-11-19)
BACKGROUND: Fitness costs and slower disease progression are associated with a cytolytic
T lymphocyte (CTL) escape mutation T242N in Gag in HIV-1-infected individuals carrying
HLA-B*57/5801 alleles. However, the impact of ...
