Filed:

Jan 24, 2001

Appl. No.:

09/769086

Inventors:

James B. Kaper - Pasadena MD
Karen Jarvis - Arnold MD

Assignee:

University of Maryland, Baltimore - Baltimore MD

International Classification:

A61K 3908

US Classification:

4242411, 4241851, 4241901, 530350, 530402, 435 71, 435 732, 435 737, 435 72, 435 6

Abstract:

Several EHEC proteins which are secreted into the culture supernatant have been discovered. These proteins are not produced by non-pathogenic , and produce a strong serum antibody response in patients with HUS and bloody diarrhea.

Abstract:

An enhanced biohazard detection system and a method for detecting, screening and analyzing biological agents are disclosed. The system incorporates an immunoassay detection device to provide a more robust, less expensive method for detecting biological agents in air samples collected at strategically located monitored sites. The immunodetection based assays may be used either in parallel with, or as a prescreening assay for, a polymerase chain reaction based assay for detecting and identifying biological agents in air samples.

Appl. No.:

12/292426

Inventors:

Raymond M. Pierson - Elkridge MD, US
Matthew W. Snyder - Elkridge MD, US
Karen G. Jarvis - Elkridge MD, US

International Classification:

C12Q 1/68
C40B 30/04

US Classification:

506 9, 435 612

Abstract:

A method for detecting a biological agent in a liquid sample is disclosed. The method comprises: passing a liquid sample through a filter in the presence of a surfactant; and subjecting the filtered sample to direct polymerase chain reaction (PCR) analysis for the presence of a biological agent, wherein the filter has a porosity that allows the biological agent to pass through the filter in its intact form.
