Campylobacter jejuni, Campylobacter coli, and a Campylobacter-like organism were isolated from a number of natural water sources in central Washington, including ponds, lakes, and small mountain streams at elevations ranging from 1,460 to 5,400 feet (ca. 445 to 1,646 m) above sea level. At the two sites where extensive sampling was done, the bacteria were… (More)
Migratory ducks, Canada geese, and sandhill crane from the Pacific North American Flyway have been screened for Campylobacter spp. Samples (298) from these birds were examined and the incidence of Campylobacter spp. in the samples were as follows: sandhill crane (Grus canadensis tabida), 81%; ducks (Aythya collaris, Anas carolinensis, Aythya americana, and… (More)
Sixty-five percent (469 of 722) of the fecal samples collected from small rodents in the central Washington Cascade mountains were positive for Giardia spp. Trapping studies showed that microtines of the genus Microtus were heavily infected with the parasite. Morphologically the cysts and trophozoites were of the Giardia duodenalis type. Small-rodent… (More)
A method of fixing and staining Giardia cysts on a membrane filter is reported. This procedure appears to be a reliable method for the recovery and detection of cysts and also for the determination of cyst densities. Evaluation and possible applications of the technique are described.
The relation between Helicobacter pylori and gastroesophageal reflux disease is unclear. Recent reports have suggested a possible protective role for H. pylori, particularly in preventing the complications of gastroesophageal reflux disease (GERD). The purpose of this article is to present a brief overview of the recent literature regarding the role of H.… (More)
A total of 189 muskrat fecal samples were surveyed for Campylobacter and Giardia species. Campylobacter jejuni was recovered from 47.5% of these samples, and Giardia species were detected in 82.5%. These findings indicate that muskrat may be of importance to the health both of humans and of domestic animals.
AIMS The aim of this study was to investigate differences in pain, range of movement function and satisfaction at three months and one year after total knee arthroplasty (TKA) in patients with an oblique pattern of kinematic graph of the knee and those with a varus pattern. PATIENTS AND METHODS A total of 91 patients who underwent TKA were included in… (More)
Blood smears from 837 mallard ducks (Anas platyrhynchos), collected during January and February from various locales in Washington during the period 1974-1977, were examined for hematozoa. Of these, 339 (40.5%) harbored blood parasites: Leucocytozoon simondi was the most common, occurring in 24.4% of the birds, followed by Haemoproteus nettionis (23.4%).… (More)
