| wound infection by an indigenous pseudomonas pseudomallei-like organism isolated from the soil: case report and epidemiologic study. | a 27-year-old farmer in the oklahoma panhandle was pinned under his overturned tractor for 2 hr and received superficial and deep lacerations. he contracted an infection of a pelvic wound with an organism that had cultural and biochemical characteristics identical to those of pseudomonas pseudomallei. identical organisms were recovered from soil taken from the site of the accident. the organism isolated from the wound proved to be less virulent in guinea pigs than usual laboratory strains of p. ... | 1977 | 833442 |

| epidemiology and clinical characteristics of tularemia in oklahoma, 1979 to 1985. | we studied the clinical and epidemiologic characteristics of tularemia in 165 oklahomans from 1979 to 1985. the ulceroglandular form of the disease was most common (60%), followed by typhoidal (18%), glandular (15%), oropharyngeal (7%), and oculoglandular (1%) forms. the male-female ratio was 3.7:1, and the highest rates of disease were found in the age groups 5 to 14, 35 to 44, and 55 to 74. ticks were most frequently implicated as the source of infection (84/154 [55%]), followed by rabbits, (5 ... | 1991 | 1891728 |
| epidemiologic characteristics of human tularemia in the southwest-central states, 1981-1987. | from 1981 through 1987, a total of 1,041 cases of tularemia in humans were reported in arkansas, kansas, louisiana, missouri, oklahoma, and texas; this represents 60% of the cases reported in the united states during this same time period. the state of arkansas reported the highest total (420 cases). annual incidence rates per one million population ranged from 36.3 in arkansas to less than 5.0 in kansas, louisiana, and texas. epidemiologic data were available for 1,026 cases. the majority of ca ... | 1991 | 2035503 |
| control of psoroptes cuniculi in captive white-tailed deer with ivermectin-treated corn. | psoroptes cuniculi, the ear mite of domestic rabbits, was collected from captive white-tailed deer (odocoileus virginianus). this is the first report of rabbit ear mite infestations in white-tailed deer in oklahoma or texas (usa). in addition to moderate infestations in their ears, two 4-yr-old bucks, two 3-yr-old does, and seven 4-yr-old does showed patchy areas of alopecia along the sides and brisket. both bucks also had patchy areas of alopecia around the base of antlers. ear mites were eradi ... | 1991 | 2067046 |
| influence of habitat modification on the intestinal helminth community ecology of cottontail rabbit populations. | the influence of five brush management treatments using the herbicides tebuthiuron and triclopyr, with or without prescribed burning, on the intestinal helminth community of cottontail rabbits (sylvilagus floridanus) was studied in 1987 on the cross timbers experimental range in payne county, oklahoma (usa). six helminth species were found (dermatoxys veligera, trichostrongylus calcaratus, passalurus nonanulatus, wellcomia longejector, taenia pisiformis cystercercus, and mosgovoyia pectinata ame ... | 1990 | 2338720 |
| the venomous hair structure, venom and life cycle of lagoa crispata, a puss caterpillar of oklahoma. | the presence of a unique population of lagoa crispata, puss caterpillar, in western oklahoma is reported. a detailed microscopic examination shows the structure of the l. crispata spines resemble the type 4 spines described by [kawamoto, f., kumada, n., 1984. biology and venoms of lepidoptera. in: tu, a.t. (ed.), handbook of natural toxins, insect poisons, allergens and other invertebrate venoms, vol. 2, pp. 291-332 (ch. 9)]. the major food source of l. crispata are the leaves of oak (shin oak). ... | 2000 | 10736472 |
| tularemia--oklahoma, 2000. | in june 2000, seven cases of tularemia were reported to the oklahoma state department of health (osdh) over an 18-day period. enhanced tularemia surveillance by osdh during july-september 2000 detected four additional cases. during 1995-1999, an average of six cases were reported each year. this report summarizes clinical and epidemiologic information from the investigation of the 11 cases, presents three case reports to illustrate different risk factors for tularemia, and underscores the danger ... | 2001 | 11787577 |
| alternate pathway of infection with hepatozoon americanum and the epidemiologic importance of predation. | the range of american canine hepatozoonosis (ach) is expanding from the southern usa northward. transmission of hepatozoon americanum occurs by ingestion of infected gulf coast ticks, amblyomma maculatum. the source of the protozoan for the tick remains undetermined; infected dogs are unusual hosts for the tick. | 2009 | 19709355 |
