Malaria transmission in non-endemic areas: case report, review of the literature and implications for public health management (2009)

Zoller, Thomas, Naucke, Torsten J, May, Jürgen, Hoffmeister, Bodo, Flick, Holger, Williams, Christopher J, ...

Abstract In non-endemic areas, malaria is rare and locally acquired infections, particularly with Plasmodium falciparum , are exceptional events. The diagnosis is, therefore, likely to be delayed or...

High-latitude Forest Structure: Methodological Considerations and Insights on Reconstructing High-latitude Fossil Forests (2007)

Christopher J. Williams

Throughout much of earth history globally warm intervals prevailed over ice age conditions. Without the constraints imposed by cold climates, forest vegetation populated high-latitude land masses....

Biomolecular preservation of Tertiary Metasequoia Fossil Lagerstätten revealed by comparative pyrolysis analysis (2005)

Yang, Hong, Huang, Yongsong, Leng, Qin, LePage, Ben A., Williams, Christopher J.

We compared structural biopolymers from morphologically well preserved Metasequoia tissues from three Tertiary deposits and detected a continuum of biochemical preservation seen in this...

Development and evaluation of a hand held computer based on-call pack for health protection out of hours duty: A pilot study (2005)

Abubakar, Ibrahim, Williams, Christopher J, McEvoy, Marian

Abstract Background The on call service for health protection in most parts of the UK is provided by general public health consultants, registrars and nurses as the first tier of response backed up...

Geographic correlation between deprivation and risk of meningococcal disease: an ecological study (2004)

Williams, Christopher J, Willocks, Lorna J, Lake, Iain R, Hunter, Paul R

Abstract Background Meningitis caused by Neisseria meningitidis is a serious infection which is most common in young children and adolescents. This study investigated the relationships between the...

Reconstruction of Tertiary Metasequoia forests. I. Test of a method for biomass determination based on stem dimensions (2003)

Christopher J. Williams, Arthur H. Johnson, Ben A. LePage, David R. Vann, Karen D. Taylor

Accurate reconstruction of the biomass, structure, and productivity of ancient forests from their fossilized remnants remains an interesting challenge in paleoecology. In well-preserved Tertiary...

Reconstruction of Tertiary Metasequoia forests. II. Structure, biomass, and productivity of Eocene floodplain forests in the Canadian Arctic (2003)

Christopher J. Williams, Arthur H. Johnson, Ben A. LePage, David R. Vann, Tatsuo Sweda

Abundant fossil plant remains are preserved in the high-latitude middle Eocene deposits of the Buchanan Lake Formation on Axel Heiberg Island, Nunavut Territory, Canada. Intact leaf litter, logs, and...

PHENOL OXIDASE ACTIVITY IN PEATLANDS IN NEW YORK STATE: RESPONSE TO SUMMER DROUGHT AND PEAT TYPE (2000)

Christopher J. Williams, Erica A. Shingara, Joseph B. Yavitt

We studied phenol oxidase (PO) activity in two Sphagnum-dominated peatlands and a Carex-dominated freshwater marsh during a strong summer drought in Central New York, USA to determine whether PO...

Effect of Cattle Diet on Escherichia coli O157:H7 Acid Resistance

Hovde, Carolyn J., Austin, Paula R., Cloud, Karen A., Williams, Christopher J., Hunt, Carl W.

The duration of shedding of Escherichia coli O157 isolates by hay-fed and grain-fed steers experimentally inoculated with E. coli O157:H7 was compared, as well as the acid resistance of the bacteria....

Ruminant Gastrointestinal Cell Proliferation and Clearance of Escherichia coli O157:H7

Magnuson, Bernadene A., Davis, Margaret, Hubele, Suzanna, Austin, Paula R., Kudva, Indira T., Williams, Christopher J., ...

Human infections with Escherichia coli O157:H7 cause hemorrhagic colitis that can progress to a life-threatening sequelae. The most common mode of disease transmission is ingestion of contaminated...

Gastrointestinal Tract Location of Escherichia coli O157:H7 in Ruminants

Grauke, Luke J., Kudva, Indira T., Yoon, Jang Won, Hunt, Carl W., Williams, Christopher J., Hovde, Carolyn J.

Experimentally inoculated sheep and cattle were used as models of natural ruminant infection to investigate the pattern of Escherichia coli O157:H7 shedding and gastrointestinal tract (GIT) location....

The Escherichia coli O157 Flagellar Regulatory Gene flhC and Not the Flagellin Gene fliC Impacts Colonization of Cattle

Dobbin, Heather S., Hovde, Carolyn J., Williams, Christopher J., Minnich, Scott A.

A virulent European Escherichia coli O157:H− isolate is nonmotile due to a 12-bp deletion in the flagellar regulatory gene flhC. To investigate the contribution of flhC in the relationship between...
