These proteases play a prominent role inthe pathogenesis of experimental pneumonia(Lyerly and Kreger, 1983) and keratitis (Lyerlyet al., 1981).

Serratia marcescens was the most common organism isolated from the corneal scrapings and from the contact lenses.

As control measures, the distributor improved hygiene measures, and the military bases thoroughly cleaned the bathrooms and kitchens, and increased awareness on hand hygiene among the soldiers. From Week 21, the kitchens in all three bases in Troms voluntarily elected to close the salad bar and refrain from serving pork products until the outbreak was resolved.

National outbreak of Yersinia enterocolitica infections in military and civilian populations associated with consumption of mixed salad, Norway, 2014.

They have no specific growth requirements and grow well on standard laboratory media, but grow best between 35 and 37 °C and at pH 7.2.

A total of 5,093 isolates were collected in 2014. Of these, 25.3% were resistant to tetracycline, 19.2% to ciprofloxacin, and 16.2% to penicillin (plasmid-based, chromosomal, or both)

n 2010, 27.2% of all GISP isolates were resistant to penicillin, tetracycline, ciprofloxacin, or some combination of those antimicrobials and 6.9% of isolates were resistant to all three antimicrobial

OUTER MEMBRANE CONSTITUENTS ASSOCIATED WITH GONOCOCCAL VIRULENCE

Up to 90 percent of pharyngeal gonorrhea in men and women may be asymptomatic

The oxidase test uses the tetramethyl derivative of the oxidase reagent

The catalase test (3% hydrogen peroxide) or superoxol (30% hydrogen peroxide) are other rapid tests used in the presumptive identification of N gonorrhoeae. A drop of the reagent is placed in the centre of a clean glass slide and the suspect colony is picked with a loop and emulsified in the reagent. N gonorrhoeae will produce a positive reaction with bubbling within 1 s to 2 s. Weak bubbling or bubbling after 3 s indicates a negative reaction (5) (Table ​(Table2).2).

The inoculated plates should be incubated at 35°C to 37°C in a moist atmosphere enriched with CO2 (3% to 7%) (5). An 18 h to 24 h culture should be used as the inoculum for additional tests. Plates should not be incubated for longer than 48 h because most old cultures would not survive storage conditions.

Our effort to identify known virulence genes revealed a surprising deficiency of toxin genes other than pvl, lukD, and lukE.

These events cause the symptoms of septic shock that occur during severe infections caused by S aureus.

S aureus cells express on their surface proteins that promote attachment to host proteins such as laminin and fibronectin that form part of the extracellular matrix

The catalase test is important in distinguishing streptococci (catalase-negative) staphylococci which are catalase positive.

more likely to occur in children younger than 5 years and people with weakened immune systems.

Later, the person's lymph nodes closest to the original scratch or bite can become swollen, tender, or painful.

About three to 14 days after the skin is broken, a mild infection can occur at the site of the scratch or bite.

Cat-scratch disease (CSD) is a bacterial infection spread by cats.

In less than four months, about 4,000 cases and 550 deaths from SARS could be traced to Liu's stay in Hong Kong.
