Selected Histologic Techniques Diff-Quik II Stain for Helicobacter pylori PRINCIPLE: Helicobacter (formerly Campylobacter) pylori is a large curved gram negative bacillus that often colonizes the mucosal surface of the stomach. The Diff-Quik II stain, similar in action to the Giemsa stain, stains the bacillus fairly sensitively, though not at all specifically. SPECIMEN: The usual specimen is a gastric or duodenal biopsy specimen, fixed in 10% formalin or neutral buffered formalin, paraffin processed, and cut in the usual fashion. Diff-Quik II can also be used as a general bacterial stain for other tissues. PROCEDURE: 1. Deparaffinize sections and hydrate to water. 2. Stain 2 to 3 minutes in Diff-Quik II stain in a Coplin jar. 3. Rinse rapidly in water. 4. Dehydrate rapidly in 100% alcohol and pass to xylene or xylene substitute. 5. Mount in resin. CONTROL: Run a control with every stain run. The control may be a gastric biopsy specimen known to be positive, or a specially prepared control (see reference below). RESULT: Bacteria and fungi are stained dark blue, with very distinct morphologic features. Cell nuclei and other histological structures are also distinctly blue. Helicobacter pylori is seen as large curved, helical, or gull-wing shaped bacilli. Gastrospirillum hominis is clearly stained and easily identified, in the author's experience of a single case.

Speed found, that Guillain-Barre Syndrome is about 90 times less likely than Campylobacteriosis Guillain-Barre Syndrome is exclusively connected with one single strain of Campylobacter, namely serotype PEN19:LIO7. This strain makes only 2% of all the Campylobacter strains . Guillain-Barre Syndrome itself is connected with HIV-infection. In Zambia of eight persons with Guillain-Barre Syndrome, which were otherwise healthy, six (75%) had in 1987 HIV-antibodies . In Zimbabwe in 1987 of 29 patients with Guillain-Barre Syndrome, otherwise healthy, 16 (55%) had HIV-antibodies. The HIV-seroprevalence at that time in the general population was estimated to be 4.3%. In 1989 five of 16 Guillain-Barre Syndrome-patients, otherwise healthy, had HIV-antibodies. In the USA of 39 persons with Guillain-Barre Syndrome, but otherwise healthy, three had HIV antibodies. In Baltimore two patients with acute Guillain-Barre Syndrome and six with chronic symptoms, all eight otherwise healthy, were found to be HIV-infected.

Alaska Natives have high rates of acute and chronic gastritis, and rates of gastric cancer twice those found in non-Natives, resulting in high rates of illness, death, and high costs of both inpatient and outpatient medical care. Recently, collaborative studies by the Centers for Disease Control and Prevention, the Indian Health Service, the Native Health Corporation, and the Mayo Clinic have found that 90% of the adults with chronic gastrointestinal bleeding have chronic gastritis possibly related to H. pylori

The causes, natural history, and therapeutic implications of gastropathy differ from gastritis: Most classification systems distinguish acute, short-term from chronic, long-term disease. The terms acute and chronic are also used to describe the type of inflammatory cell infiltrate. Acute inflammation is usually associated with neutrophilic infiltration, while chronic inflammation is usually characterized by mononuclear cells, chiefly lymphocytes, plasma cells and macrophages. A practical clinicopathologic framework for the classification of gastritis and gastropathy based upon these factors can be proposed ( show table 1 Acute and chronic gastritis due to Helicobacter pylori will be reviewed here [

The catalase-positive organism has 4-6 sheathed flagella attached to one pole which allow for motility. History Barry Marshall and Robin Warren of Perth, Western Australia, discovered H. pylori in 1983. Originally, the organism was named Campylobacter pyloridis because it was structurally similar to other Campylobacter species, such as C. jejuni C. jejuni is a gut pathogen which has the ability to colonize the gastric mucosa. C. pyloridis was renamed Campylobacter pylori to fit in with the names of other enteric pathogens. In 1989, it was finally named Helicobacter pylori based on functional and enzymatic properties. Linkage to Gastrointestinal Disease Studies have linked H. pylori to gastrointestinal disease in humans. Even though H. pylori

In response to: Clinical Update: E. coli , antibiotics and hemolytic-uremic syndrome in children Marc Romney Affiliation: Medical Microbiology, University of British Columbia Posted on: September 26, 2000 Dear Editor, I read with interest Dr. Farquhar's summary of the recently published Wong CS et. al article (Clinical Update CMAJ Aug. 22, 2000). I was a bit perplexed by the last sentence under Implications for practice: "The findings of this study strongly suggest that these drugs should be withheld in children with acute diarrheal illness until stool cultures confirm growth of an organism for which therapy is indicated (e.g. Campylobacter pylori)." Did Dr. Farquhar mean Campylobacter jejuni? As you are most probably aware, Campylobacter pylori has been renamed Helicobacter pylori. It does not cause a diarrheal illness, nor is it routinely grown from stool cultures. Yours truly, Marc Romney UBC Medical Microbiology St. Paul's Hospital

DISCUSION Los resultados obtenidos, demostraron que el Helicobacter crece muy bien en el medio HPM, el cual tiene de particular la presencia de carbón activado. Como se ha informado previamente (9), su importancia puede radicar en su capacidad de absorber o inactivar factores tóxicos que resultan del metabolismo bacteriano. El uso de antibióticos es necesario para impedir la proliferación de contaminantes exógenos y, con más frecuencia, de contaminantes endógenos presentes en las biopsias (9-11), principalmente en los pacientes con cáncer gástrico (12-13). El crecimiento del Helicobacter en medio líquido es difícil, debido en parte a que la bacteria requiere una excelente dispersión de gases a través del medio, de un suplemento nutritivo adecuado y de un inóculo inicial denso (8). FIGURA 1. Detección de anticuerpos anti H.pylori por inmunotransferencia. En todos los pacientes con cáncer gástrico, se encontraron anticuerpos anti-H. pylori, mientras que la bacteria fue detectada sólo en 29,4%. Este resultado indica que aunque la bacteria no sea detectada, existió al menos una infección previa. En varios trabajos se ha demostrado que la bacteria puede desaparecer en los casos de atrofia gástrica o puede ser desplazada por otros microorganismos que colonizan el estómago (19-20). Estos resultados indicarían que el dato serológico global sería de poca utilidad en el estudio de estas patologías gástricas; no obstante, es importante determinar si los perfiles de respuesta obtenidos reflejan formas de interacción cuyo análisis sería de valor tanto para el diagnóstico como para el manejo y el seguimiento.

The test is to be used as an aid in the diagnosis of infection due to H. pylori, formely known as Campylobacter pylori. Summary and Explanation H. pylori is a spiral, flagellated gram negative bacteria. It colonizes the gastric epithelium of humans and plays a causative role in a variety of gastrointestinal disorders including non-ulcer dyspepsia, duodenal and gastric ulcers, active and chronic gastritis and perhaps the gastric cancer [1-10]. The WHO has designated it as a Class I carcinogen [5]. In patients with signs and symptoms of gastritis, duodenal ulcer or non-ulcer dyspepsia the prevalence rates for H. Pylori infection can exceed 90 percent. Among subjects with a parental history of stomach cancer a much higher prevalence of H. pylori

Forces International Back to The evidence SMOKING DOES NOT CAUSE ULCERS OR STOMACH CANCER Back to main page GASTRIC ULCER: According to an editorial in the New England Journal of Medicine, "We now recognize three major causes of peptic ulcer disease: Helicobacter pylori infection, the use of nonsteroidal anti-inflammatory drugs (NSAIDs), and pathologic hypersecretory states such as the Zollinger-Ellison syndrome... H. pylori infection is the most common known cause of peptic ulcer and accounts for the majority of cases. NSAIDs are the second most common cause and are responsible for the majority of cases not caused by H. pylori infection." (DY Graham. Treatment of peptic ulcers caused by Helicobacter pylori. NEJM 1993;328(5):349-350). Out of 115 consecutive gastric ulcer patients, 61% were HP positive, including 30% who also used NSAIDs. Of 44 HP negatives, 66% used NSAIDs, 5% had malignant GUs, and 30% were of unknown cause. Only 11% of total GUs were of unknown cause. (TJ Borody, S Brandl et al.
