A 19-year-old man, recently returned from a 10-day military exercise in central California, had acute onset of shaking chills, headache, and bilateral inguinal adenopathy after having been bitten by insects on his lower extremities. He had exquisitely tender inguinal and femoral nodes bilaterally. Needle aspirate from an inguinal node grew Yersinia pestis. The patient was treated with streptomycin and chloramphenicol and did well.

Milk and cold meat samples were contaminated with 7 various serogroups of Yersinia enterocolitica strains. The infected food samples were incubated under different conditions of growth, at different temperatures and for different periods of time, then the number of colony forming units was determined and enterotoxin production was assayed by the suckling mice test. The Y. enterocolitica strains multiplied well under varying conditions of growth, but enterotoxin production could be detected only in the meat samples when incubated under shaking at 25 degrees C for 48 h. It may be assumed that performed yersinia enterotoxin is absent from food stored under normal conditions.

An 82-year-old man was admitted because of abdominal pain and a shaking chill. His medical history revealed ileocecal resection because of ileitis associated with a Yersinia infection 3 years before admission. One year later he was readmitted because of bowel obstruction due to recurrent ileitis. He was treated with trimethoprim-sulfamethoxazole for two weeks because of positive serological tests for Yersinia and made a full recovery except for chronic diarrhoea. On the current admission, stool cultures yielded Campylobacter upsaliensis. Further analysis showed severe non-specific ulcerative ileitis without colitis. A diagnosis of Crohn's disease was made. The patient was treated with prednisone and mesalazine and made a full recovery. The chronic diarrhoea disappeared. The course was complicated by a cerebro-vascular thrombosis and severe thrombocytosis due to polycythaemia vera. Treatment with hydroxyurea was effective in lowering the thrombocyte count.

We report a case of transfusion-mediated Yersinia enterocolitica septicemia in a 43-y-old woman with homozygous beta-thalassemia. Two h after transfusion of 3 units of red blood cells the patient suffered high-grade fever and shaking chills. Y. enterocolitica serotype O3 grew in blood cultures. Prolonged treatment with i.v. ceftriaxone plus ciprofloxacin led to a favorable outcome. Transfusion-associated Y. enterocolitica septicemia has not previously been reported in an adult beta-thalassemic patient from the Mediterranean area. Our report is particularly important, because of the high incidence of chronically transfused thalassemic patients in Mediterranean countries.

The effects of surface type (stainless steel, acetal resin, and fiberglass reinforced plastic wall paneling [FRP]), soil, and temperature on the survival of Listeria monocytogenes, Salmonella spp., and Yersinia enterocolitica, in the presence of condensate were evaluated. Surface coupons--half soiled with sterile porcine serum--were exposed to cell suspensions made from individual five-strain cocktails composed of organisms from the same genus (10(7) CFU/ml) in Butterfield's phosphate buffer and incubated for 2 h at 25 degrees C allowing attachment of cells to coupon surfaces. Coupons were rinsed to remove unattached cells, incubated at either 4 or 10 degrees C under condensate-forming conditions, and sampled at six time intervals over a 15-day period. For enumeration, cells were removed from the coupons by vigorous shaking in 100 ml of Butterfield's phosphate buffer with 3 g of glass beads and plated on tryptic soy agar with 0.6% yeast extract. Stainless steel did not support the survival of Listeria as well as acetal resin or FRP. Acetal resin and stainless steel were less supportive of Salmonella than FRP. All surfaces supported the survival of Yersinia over the 15-day trial equally. Temperature had little effect on survival of all organisms across all surfaces with one exception. However, Yersinia displayed growth on FRP at 10 degrees C. but death at 4 degrees C. Serum had a protective effect on L. monocytogenes on all surfaces, with populations sustained at significantly (P < or = 0.05) higher numbers over time than unsoiled coupons. Serum didnot effect survival of Salmonella or Yersinia on stainless steel, acetal resin, or FRP.

Yersinia pestis, the causative agent of plague, autoaggregates within a few minutes of cessation of shaking when grown at 28 degrees C. To identify the autoaggregation factor of Y. pestis, we performed mariner-based transposon mutagenesis. Autoaggregation-defective mutants from three different pools were identified, each with a transposon insertion at a different position within the gene encoding phosphoglucomutase (pgmA; y1258). Targeted deletion of pgmA in Y. pestis KIM5 also resulted in loss of autoaggregation. Given the previously defined role for phosphoglucomutase in antimicrobial peptide resistance in other organisms, we tested the KIM5 DeltapgmA mutant for antimicrobial peptide sensitivity. The DeltapgmA mutant displayed >1,000-fold increased sensitivity to polymyxin B compared to the parental Y. pestis strain, KIM5. This sensitivity is not due to changes in lipopolysaccharide (LPS) since the LPSs from both Y. pestis KIM5 and the DeltapgmA mutant are identical based on a comparison of their structures by mass spectrometry (MS), tandem MS, and nuclear magnetic resonance analyses. Furthermore, the ability of polymyxin B to neutralize LPS toxicity was identical for LPS purified from both KIM5 and the DeltapgmA mutant. Our results indicate that increased polymyxin B sensitivity of the DeltapgmA mutant is due to changes in surface structures other than LPS. Experiments with mice via the intravenous and intranasal routes did not demonstrate any virulence defect for the DeltapgmA mutant, nor was flea colonization or blockage affected. Our findings suggest that the activity of PgmA results in modification and/or elaboration of a surface component of Y. pestis responsible for autoaggregation and polymyxin B resistance.

Five systems were compared for their ability to break up chains and clumps of organisms for enumeration. The highest aerobic plate counts of Bacillus cereus were obtained by mixing the organism in the Waring blendor or the Osterizer. Significantly lower counts were obtained by stomaching, shaking or shaking with beads. Results similar to those of B. cereus were obtained when Staphylococcus aureus and Streptococcus faecalis were prepared for enumeration using these five systems. There was no significant difference in aerobic plate counts obtained by using the five systems with Yersinia enterocolitica as the test organism.
