JOURNAL FREE ACCESSMortality from gastric ulceration and total mortality in 16, 701 foals from 1997 to 1999 were compared. Clinical signs and gastric-ulcer sites and severity were examined in 40 foals. Mortality from gastric ulcers was 13.6% in 1997, 16.2% in 1998, and 7.1% in 1999. Mean age at initial examination was 61.9±27.5 days in the live group and 78.3%±37.7 days in the dead group. Medical treatment lasted for less than 10 days in the greater number of animals (P<0.01). Clinical signs were diarrhea (65.0%), depression (82.5%), intermittent nursing (82.5%), colic (37.5%), bruxism (10.0%), and ptyalism (7.5%). Ulcerous lesions in the stomach were observed along the greater curvature in the Margo plicatus (87.5%), along the lesser curvature of the Margo plicatus (82.5%), in the squamous fundus (92.5%), and in the glandular fundus (60.0%). Severity was greater in gastric ulcers occurring along the greater and lesser curvatures of the Margo plicatus.View full abstractDownload PDF (625K) -

JOURNAL FREE ACCESSHematological examinations of an 11-month-old exophthalmic heifer on a Japanese Black cattle breeding farm revealed a slight increase in white blood-cell numbers. Autopsy showed a localized collection of pus in the pituitary gland. Histological examination uncovered a pituitary-gland abscess and lymphocyte infiltration around the tissue. Arcanobacterium (Actinomyces) pyrogenes was isolated from the abscess.View full abstractDownload PDF (1211K) -

JOURNAL FREE ACCESSBetween May and June 1998, 17 farmed wild boars (Sus scrofa) on a farm in Kochi Prefecture died suddenly. Pathological and bacteriological examinations of 3 of the 17 animals confirmed an outbreak of septicemic erysipelas. Macroscopic examinations showed that cyanosis, enlarged lymph nodes, gastric and duodenal mucosal hemorrhage, and renal petechiae characterized the dead animals. Histological examination revealed thrombosis, histiocytosis, suppurative necrotic lymphadenitis, suppurative interstitial nephritis, and endoproliferative glomerulonephritis. Erysipelothrix rhusiopathiae serotype la was isolated from various organs including the lymph nodes. Although multidrug-resistant to other anitimicrobials, the isolates were highly suscentible to penicillins and were virulent enough to induce generalized erythema in swine.Immunostaining for E. rhusiopathiae serotype la produced postive reactions in macrophages and thrombi of various organs, especially the kidneys, spleen, and lymph nodes. Disinfection, penicillin administration, and vaccination eradicated the erysipelas endemic to the farm. The animals' high susceptibility to E. rhusiopathiae, their fierceness, the long fattening period (over two years), and the lack of legal meat-inspection obligations put serious obstacles in the way of preventing erysipelas in farmed Japanese wild boars.View full abstractDownload PDF (2922K) -

JOURNAL FREE ACCESSA total of 120 swine stomachs collected at a slaughterhouse in Gifu Prefecture was examined for the presence of Gastrospirillum-like organisms (GLO). All the pigs investigated had been slaughtered as healthy animals. Of 120 pigs, gastric ulcers were observed in 30 (25.0%) and erosion in 41 (34.2%). Of 21 pigs with spiral bacteria in the stomach mucosa, 8 (26.7%) demonstrated gastric ulcers, 9 (22.0%) erosion, 2 (9.5%) chronic gastritis, and 2 (7.1%) normal gastric mucosa. Ordinary bacteriological methods, however, cultured no GLO from any of the pigs. Spiral bacteria were found immersed in the mucous layer or inside gastric foveolae. Occasionally they were found in the lumens of gastric glands. The presence of GLO was seen as significantly associated (P<0.05) with the incidence of gastric ulcer and erosion.View full abstractDownload PDF (2176K) -

JOURNAL FREE ACCESSEighty Holstein steers affected with acute respiratory diseases were treated intramuscularly with cefquinome, a fourth-generation cephem antibiotic with a short withdrawal period. Therapeutic effects were compared with those of ceftiofur, a third-generation cephem antibiotic, by the clinical and microbiological standpoints. Pasteurella multocida and/or P. haemolytica, known to be major causative organisms in acute bovine respiratory diseases, were isolated from these steers. No difference was observed in antibiotic therapeutic effects between diseases caused by Pasteurella spp. and those caused by otherbacteria. Cefquinome had a 98.1% clinical efficacy, which is comparable to that of ceftiofur. At reexammation performed 7 days after final administration, no clinical recurrence was observed.View full abstractDownload PDF (555K) -

JOURNAL FREE ACCESSIn the animal-clinic environment we conducted oscillometric blood-pressure measurements on 215 healthy dogs brought to the clinic for reasons other than treatment of disease. Measurements were made at the for-eleg, hind leg, and tail. Although heart rates were the same at all sites, measured diastolic pressure and meanblood pressure were highest at the hind leg followed by the foreleg then the tail. In consideration of ease of measurement in the clinical setting and experimental results, blood pressure in all dogs was measured at the foreleg with the following results: systolic pressure 132.0±17.4 mmHg, diastolic pressure 86.6 ± 14.2 mmHg, and mean blood pressure 106.2±14.5 mmHg. Blood pressure was found to increase with age, and males tend-ed to have higher blood pressure than females.View full abstractDownload PDF (1543K) -

JOURNAL FREE ACCESSAntihypertensive effect of exposure alternating current, high-voltage, electrical potential (AC-HVEP) were investigated in Dahl salt-sensitive (Dahl-S) rats used as models of salt-induced hypertension. The animals were divided into two groups: rats exposure to AC-HVEP (AC-HVEP group) and a control group not exposed to AC-HVEP. Throughout the experimental period, water with an addition of 1.0% NaC1 was given the animals. Progressive hypertension in the AC-HVEP group was significantly less serious than in the control group. In addition, histopathological examination showed greater restriction of lesions in the AC-HVEP than in the control group. Our results suggest that AC-HVEP exposure can suppress progressive hypertension secondary to chronic renal failure.View full abstractDownload PDF (2315K) -

JOURNAL FREE ACCESSThe effects of midazolam (0.3 mg/kg IV) alone or with the addition of butorphanol (0.0125, 0.025, 0.05, and 0.1 mg/kg IV, groups A, B, C, D, and E, n = 40 each) as combinations for premedication before inhalation anes-thesia were evaluated in 200 dogs [ASA Classes I (n= 89), II (n= 86), and III (n = 25)]. Surgical anesthesia was induced by ketamine (5mg/kg IV) and maintained with 50% nitrous oxide-50% oxygen -sevoflurane. All dogs of ASA Class III grew calm and relaxed and assumed a sternal position after premedication. Dogs of Class-es I and II demonstrated mild to moderate sedation and dose-dependent sedative effects caused by butor-phanol. In several dogs of ASA Class I in each group, intratracheal intubation was impossible after ketamme injection. In these cases, mask-induced oxygen-sevoflurane anesthesia was followed by intubation. Heart and respiratory rates decreased minimally after premedication; and, in groups D and E, respiratory rate decreased significantly after induction to anesthesia. End-tidal sevoflurane concentrations during surgery varied from 2.4-2.6% in group A, 2.0-2.1% in group B, 2.3-2.4% in group C, 2.0-2.2% in group D, and 2.1-2.2% in groupE. In all instances, during surgery, heart rate (130 bpm), mean arterial blood pressure (90-110 mmHg), res-piratory rate (30 bpm), and partial pressure of end-tidal CO2 (40 50 mmHg) remained with normal canine lim-its. Recovery from anesthesia was rapid, and most dogs were extubated by 10 minutes after anesthesia cessa-tion. The combination of midazolam and butorphanol is useful premedication for dogs of ASA Classes II and IIIView full abstractDownload PDF (1302K) -

JOURNAL FREE ACCESSA questionnaire surver was conducted of animal breeding in 72 nursing homes for the ages. Numerous institutions breed animals with the aim of improving, inmates' quality of life. Many of the institution conducting no such programs cited as reasons concern with the burden of animal breeding, insufficient, equipment, and the danger of zoonotic infection. Of the 72 institutions surveyed, 30 expressed hope of calling on volunteers in animal-assisted activities.View full abstractDownload PDF (748K) -

JOURNAL FREE ACCESSIn Shizuoka, between 1987 and 1999, 190 enterohemorrhagic Escherichia coli (EHEC) O157 strains (140 from human feces and 50 from cattle sources) collected were subjmitted for phage typing. Of these, 184 strains (96.8%) were phage typed. In the human strains, 17 different phage types (PT 1, 2, 4, 8, 14, 21, 23, 24, 28, 31, 32, 33, 34, 37, 45, 54, and 61) were identified. In cattle strains, 11 different phage types (PT 1, 8, 14, 23, 32, 33, 34, 39, 54, 63, and 74) were identified. Predominant phage types were PT 2, 4, 21, and 32 in human strains andPT 14, 23, 34, and 54 in cattle strains. Eight phage types (PT 1, 8, 14, 23, 32, 33, 34, and 54) were common in both sources. PT 21 and 34 were observed in 2 group-outbreak isolates; PT 2, 4, 8, 21, 23, 24, 32, 37, 45, and 54 were observed in 21 family-outbreak isolates. Phage types of strains isolated from the same outbreak (group or family) were the same. These results suggest that the phage-typing scheme is useful in studying causative factors in epidemiological investigations.View full abstractDownload PDF (728K) -
