PEP regimens are designed to prevent infection in individuals who have known or potential exposure to an infectious agent
but are not symptomatic.
Compared with other diseases caused by a single infectious agent
, tuberculosis is the second biggest killer, globally.
R seeberi has not been definitively cultured but is thought to be a blue-green algae, with the infectious agent
being a thick-walled sporangium containing endospores.
* Monitoring, documenting, and controlling environmental conditions: Is the proper Biosafety Level being used for the suspected infectious agent
The various criteria used for classifying an infectious agent
to be associated with congenital cataract include demonstration of the specific IgM antibodies in the serum, isolation of the infectious agent
and detection of the nucleic acid of the infectious agent
from various clinical specimens from the infected foetus or new born.
The team used sponge-like microparticles that slowly release a characteristic bacterial "scent" to mimic an infectious agent
. Using focused beams of light--known as holographic optical tweezers--to move the mini sponges and control the pattern of released chemicals over space and time, they could study how immune cells respond.
Each PathAlert Detection Kit is a reagent system optimized for the detection of a specific infectious agent
. Based on multiplex-PCR, the kits detect multiple regions of pathogen DNA and include internal and external controls, greatly reducing false-positive and false-negative readings.
Dow Jones Newswires reports that the original rule prohibits the use of cattlederived materials that can carry the infectious agent
for mad cow disease.
Shu Chen, associate director of the National Prion Disease Pathology Surveillance Center at Case Western Reserve University in Cleveland, Ohio, explains why: "The current understanding is the prion is an infectious agent
made up of an abnormal form of protein."
Recently, a new infectious agent
from Asia has become the first new major infectious threat of the 21st century.
These are complex relationships to be sure, regardless of whether they involve our exposure to a weather change or infectious agent
("bug") or reflect our succumbing to the pressures of work, relationship, or other life stress.
Variant CJD began to emerge and be diagnosed in the mid-1990 and is thought to be caused by an infectious agent
called a prion, which can be carried in blood and tissue which causes the death of brain cells.
