What is the pathogenesis of C. jejuni-related disease?
Campylobacters are small
Gram-negative spiral rods. Campylobacter jejuni (C. jejuni), a
foodborne organism contracted from untreated water, milk and meat,
especially chicken, is one of the most important causes of bacterial
diarrhea worldwide. However, its mode of pathogenesis is not clear.

At Least 336 Sick in Multi-State Salmonella Typhimurium Outbreak
A
multi-state investigation with over two dozen states and the U.S.
Centers for Disease Control and Prevention has yet to identify the
source of an outbreak of Salmonella Typhimurium.
Cases, some of which date back to October 2008, match each other by
their DNA fingerprint (PFGE) and appear to have a common origin, the
CDC said. In all, there are 336 cases nationwide have the same PFGE.

How do Lactobacilli treat Helicobacter pylori-related diseases?
Some studies have demonstrated
H. pylori
stimulates the release of interleukin-8 (IL-8) from gastric epithelia,
which initiates inflammatory damage to gastric mucosa and plays a
crucial role in the pathogenesis of
H. pylori
H. pylori lipopolysaccharide (
H. pylori-LPS) is the major initiator in
H. pylori-induced
IL-8 production via activation of Toll-like receptor 4 (TLR4) pathway
in gastric epithelia.

Outbreak of Multidrug-Resistant Salmonella enterica serotype Newport Infections Associated with Consumption of Unpasteurized Mexican-Style Aged Cheese
During March 2006--April 2007, an outbreak of
Salmonella enterica serotype Newport infections
occurred predominantly among Hispanics in northeastern Illinois. Samples from 85 patients, one sample of Mexican-style
aged cheese (cotija) from a local Hispanic grocery store (grocery store A), and milk from a bulk tank on a local dairy
farm tested positive for
S. Newport and had indistinguishable pulsed-field gel electrophoresis (PFGE) patterns. This
report summarizes the investigation into
S. Newport infections associated with this outbreak. The findings emphasize the
need for regulatory authorities to ensure that dairy products, including Mexican-style cheese, are manufactured
and distributed by inspected sources and highlight the need for culturally targeted education of consumers and
grocery-store operators regarding risks associated with consuming unpasteurized dairy products.

friends and family to a buffet. However, this type of food service
where foods are left out for long periods leave the door open for
uninvited guests -- bacteria that cause foodborne illness. Festive
times for giving and sharing should not include sharing foodborne
illness. Here are some tips from the USDA's Meat and Poultry Hotline to

Poultry workers at increased risk of carrying antibiotic-resistant E. coli
Poultry workers in the United States are 32 times more likely to carry E. coli bacteria resistant to the commonly used antibiotic, gentamicin, than others outside the poultry industry, according to a recent study conducted by researchers at the Johns Hopkins Bloomberg School of Public Health. While drug-resistant bacteria, such as E. coli, are common in the industrial broiler chicken environment, this is the first U.S. research to show exposure occurring at a high level among industrial poultry workers. The results are published in the December, 2007, edition of Environmental Health Perspectives.

Key facts about MRSA infections in the United States
“MRSA” has been featured in the news and on television programs a great deal recently. MRSA stands for methicillin-resistant Staphylococcus aureus. This type of bacteria causes “staph” infections that are resistant to treatment with some antibiotics. For some expert advice about MRSA, we’ll be talking today with Jeff Hageman, an epidemiologist with CDC’s Division of Healthcare Quality Promotion.
