Surveillance for tick-borne viruses near the location of a fatal human case of Bourbon virus (Family Orthomyxoviridae: Genus Thogotovirus) in Eastern Kansas, 2015
Savage HM , Godsey MS Jr , Panella NA , Burkhalter KL , Manford J , Trevino-Garrison IC , Straily A , Wilson S , Bowen J , Raghavan RK . J Med Entomol 2018 55 (3) 701-705 Bourbon virus (Family Orthomyxoviridae: Genus Thogotovirus) was first isolated from a human case-patient residing in Bourbon County, Kansas, who subsequently died. Before becoming ill in late spring of 2014, the patient reported several tick bites. In response, we initiated tick surveillance in Bourbon County and adjacent southern Linn County during spring and summer of 2015. We collected 20,639 host-seeking ticks representing four species from 12 sites. Amblyomma americanum (L.) (Acari: Ixodidae) and Dermacentor variabilis (Say) (Acari: Ixodidae) accounted for nearly all ticks collected (99.99%). Three tick pools, all composed of adult A. americanum ticks collected in Bourbon County, were virus positive. Two pools were Heartland virus (Family Bunyaviridae: Genus Phlebovirus) positive, and one was Bourbon virus positive. The Bourbon virus positive tick pool was composed of five adult females collected on a private recreational property on June 5. Detection of Bourbon virus in the abundant and aggressive human-biting tick A. americanum in Bourbon County supports the contention that A. americanum is a vector of Bourbon virus to humans. The current data combined with virus detections in Missouri suggest that Bourbon virus is transmitted to humans by A. americanum ticks, including both the nymphal and adult stages, that ticks of this species become infected as either larvae, nymphs or both, perhaps by feeding on viremic vertebrate hosts, by cofeeding with infected ticks, or both, and that Bourbon virus is transstadially transmitted. Multiple detections of Heartland virus and Bourbon virus in A. americanum ticks suggest that these viruses share important components of their transmission cycles. |
Cardiometabolic risk assessments by body mass index z-score or waist-to-height ratio in a multiethnic sample of sixth-graders
Kahn HS , El Ghormli L , Jago R , Foster GD , McMurray RG , Buse JB , Stadler DD , Trevino RP , Baranowski T , Healthy Study Group . J Obes 2014 2014 421658 Convention defines pediatric adiposity by the body mass index z-score (BMIz) referenced to normative growth charts. Waist-to-height ratio (WHtR) does not depend on sex-and-age references. In the HEALTHY Study enrollment sample, we compared BMIz with WHtR for ability to identify adverse cardiometabolic risk. Among 5,482 sixth-grade students from 42 middle schools, we estimated explanatory variations (R (2)) and standardized beta coefficients of BMIz or WHtR for cardiometabolic risk factors: insulin resistance (HOMA-IR), lipids, blood pressures, and glucose. For each risk outcome variable, we prepared adjusted regression models for four subpopulations stratified by sex and high versus lower fatness. For HOMA-IR, R (2) attributed to BMIz or WHtR was 19%-28% among high-fatness and 8%-13% among lower-fatness students. R (2) for lipid variables was 4%-9% among high-fatness and 2%-7% among lower-fatness students. In the lower-fatness subpopulations, the standardized coefficients for total cholesterol/HDL cholesterol and triglycerides tended to be weaker for BMIz (0.13-0.20) than for WHtR (0.17-0.28). Among high-fatness students, BMIz and WHtR correlated with blood pressures for Hispanics and whites, but not black boys (systolic) or girls (systolic and diastolic). In 11-12 year olds, assessments by WHtR can provide cardiometabolic risk estimates similar to conventional BMIz without requiring reference to a normative growth chart. |
Review of brucellosis cases from laboratory exposures in the United States, 2008-2011, and improved strategies for disease prevention
Traxler RM , Guerra MA , Morrow MG , Haupt T , Morrison J , Saah JR , Smith C , Williams C , Fleischauer AT , Lee PA , Stanek D , Trevino-Garrison I , Franklin P , Oakes P , Hand S , Shadomy SV , Blaney DD , Lehman MW , Benoit TJ , Stoddard RA , Tiller RV , De BK , Bower W , Smith TL . J Clin Microbiol 2013 51 (9) 3132-6 Five laboratory-acquired brucellosis (LAB) cases that occurred in the United States between 2008 and 2011 are presented. The Centers for Disease Control and Prevention (CDC) reviewed the recommendations published in 2008 and the published literature to identify strategies to further prevent LAB. The improved prevention strategies are described. |
Phylogeographical footprint of colonial history in the global dispersal of human immunodeficiency virus type 2 group A
Faria NR , Hodges-Mameletzis I , Silva JC , Rodes B , Erasmus S , Paolucci S , Ruelle J , Pieniazek D , Taveira N , Trevino A , Goncalves MF , Jallow S , Xu L , Camacho RJ , Soriano V , Goubau P , de Sousa JD , Vandamme AM , Suchard MA , Lemey P . J Gen Virol 2012 93 889-99 Human immunodeficiency virus type 2 (HIV-2) emerged in West Africa and has spread further to countries that share socio-historical ties with this region. However, viral origins and dispersal patterns at a global scale remain poorly understood. Here, we adopt a Bayesian phylogeographic approach to investigate the spatial dynamics of HIV-2 group A (HIV-2A) using a collection of 320 partial pol and 248 partial env sequences sampled throughout 19 countries worldwide. We extend phylogenetic diffusion models that simultaneously draw information from multiple loci to estimate location states throughout distinct phylogenies and explicitly attempt to incorporate human migratory fluxes. Our study highlights that Guinea-Bissau, together with Cote d'Ivoire and Senegal, have acted as the main viral sources in the early stages of the epidemic. We show that convenience sampling can obfuscate the estimation of the spatial root of HIV-2A. We explicitly attempt to circumvent this by incorporating rate priors that reflect the ratio of human flow from and to West Africa. We recover four main routes of HIV-2A dispersal that are laid out along colonial ties: Guinea-Bissau and Cape Verde to Portugal, Cote d'Ivoire and Senegal to France. Within Europe, we find strong support for epidemiological linkage from Portugal to Luxembourg and to the UK. We demonstrate that probabilistic models can uncover global patterns of HIV-2A dispersal providing sampling bias is taken into account and we provide a scenario for the international spread of this virus. |
Swine influenza virus A (H3N2) infection in human, Kansas, USA, 2009
Cox CM , Neises D , Garten RJ , Bryant B , Hesse RA , Anderson GA , Trevino-Garrison I , Shu B , Lindstrom S , Klimov AI , Finelli L . Emerg Infect Dis 2011 17 (6) 1143-4 Triple-reassortant swine influenza viruses (SIVs), which contain genes from human, swine, and avian influenza A viruses, have been enzootic among swine herds in the United States since the late 1990s. Although uncommon, occasional transmission of triple-reassortant SIVs from swine to humans has occurred. Before April 2009, only limited, nonsustained human-to-human transmission of SIVs had been reported. Although an animal source for pandemic (H1N1) 2009 virus has yet to be identified, the pandemic strain resulted from the reassortment of 2 different lineages of SIV. |
Outbreak of Burkholderia cepacia complex among ventilated pediatric patients linked to hospital sinks
Lucero CA , Cohen AL , Trevino I , Rupp AH , Harris M , Forkan-Kelly S , Noble-Wang J , Jensen B , Shams A , Arduino MJ , Lipuma JJ , Gerber SI , Srinivasan A . Am J Infect Control 2011 39 (9) 775-8 We investigated a cluster of Burkholderia cepacia complex colonization in ventilated pediatric patients. Isolates from 15 patients, 2 sink drains, and several ventilator components were found to belong to a single B cenocepacia clone. Hospital tap water used during oral and tracheostomy care was identified as the most likely mechanism for transmission. |
