Torsion of abdominal organs in sows: a report of 36 cases   总被引：3，自引：3，他引：0       下载免费PDF全文

Morin M  Sauvageau R  Phaneuf JB  Teuscher E  Beauregard M  Lagacé A 《The Canadian veterinary journal. La revue veterinaire canadienne》1984,25(12):440-442

Necropsy records of 36 sows with torsion of abdominal organs involving individually the stomach, the spleen, a liver lobe or the intestine were reviewed for the years 1970 to 1983, and the age, the clinical signs and the gross lesions were recorded. These acute abdominal accidents were characterized clinically by sudden death. Dry sows from large breeding units were affected. Twenty-six cases were diagnosed between January 1981 and December 1983 while only ten cases had been seen between 1970 and 1980. Gastric torsion was the most common condition (40% of the cases) and the other three conditions were equally represented (20% each). Management practises that could be responsible for the apparent increase in occurrence of this problem are discussed.  相似文献   

Papovavirus induced feather abnormalities and skin lesions in the budgerigar: clinical and pathological findings   总被引：3，自引：2，他引：1       下载免费PDF全文

Bernier G  Morin M  Marsolais G 《The Canadian veterinary journal. La revue veterinaire canadienne》1984,25(8):307-310

Feather abnormalities and skin lesions caused by a papovavirus infection in budgerigars are described. Diseased one to 15 day old birds displayed a lack of nestling down feathers and filoplumes on the head and neck. Survivors older than 15 days exhibited retarded growth and temporary absence of feathers variable from bird to bird. Several birds between 15 and 25 days of age had flight feathers with total absence or marked sparseness of the vanes. After 25 days, feathers began to grow, although the tail and/or some flight feathers of some of the birds remained underdeveloped or absent for several weeks. Several of these affected birds were unable to fly and are called “runners”

Microscopic lesions in the feather follicles of the affected birds less than 15 days of age, were characterized by focal, multifocal or diffuse ballooning degeneration in the lateral and axial plate cells of the barb ridges with the presence of large basophilic or amphophilic intranuclear inclusions in the same cells. Focal areas of ballooning degeneration with intranuclear inclusions were also found in the epidermis. Clinical observations made on these birds are compared with those reported in the literature for French molt.

Fine needle aspiration biopsy of malignant tumors in dogs and cats: a report of 102 cases          下载免费PDF全文

Ménard M  Fontaine M  Morin M 《The Canadian veterinary journal. La revue veterinaire canadienne》1986,27(12):504-510

Fine needle aspiration biopsy is a fast and inexpensive technique well tolerated by animals. Its efficacy for the diagnosis of malignancy and determination of cellular origin was investigated for 97 malignant tumors and five benign lesions in 83 dogs and 19 cats. Histological examination of the lesions was performed in each case. Malignancy was detected by cytology in 69% of the malignant tumors. The cellular origin of the lesion was determined in 74% of the cases. Confirmation of malignancy and determination of cellular origin permitted an early diagnosis and prognosis. Since fine needle aspiration biopsy and cytology cannot definitely rule out malignancy, a surgical biopsy and histopathology should be done when malignancy is suspected clinically and not confirmed cytologically. Specimens of good quality, adequate collaboration between the cytologist and clinicians, and sufficient knowledge of pathology and cytology are basic requirements for obtaining good results with fine needle aspiration biopsy and cytology.  相似文献   

Transitional Cell Carcinoma of the Urinary Bladder in a Beluga Whale (Delphinapterus leucas)   总被引：1，自引：0，他引：1       下载免费PDF全文

Martineau D  Lagacé A  Massé R  Morin M  Béland P 《The Canadian veterinary journal. La revue veterinaire canadienne》1985,26(10):297-302

A transitional cell carcinoma of the urinary bladder was found in a beluga whale stranded in the St. Lawrence middle estuary. Various organs of this animal were submitted to high resolution gas chromatography coupled with mass spectrometry analysis. High frequency of urinary bladder cancer in the human population of the same area and the presence of carcinogenic compounds in the marine environment of this animal are discussed.

Concurrent isolation of Edwardsiella tarda from various organs of this whale is also reported.

Experimental transmission of intestinal coccidiosis to piglets: clinical, parasitological and pathological findings.   总被引：2，自引：0，他引：2       下载免费PDF全文

Y Robinson  M Morin  C Girard    R Higgins 《Canadian journal of veterinary research》1983,47(4):401-407

Twenty-eight piglets coming from a "specific pathogen free" herd were inoculated at three days of age with 50 000 or 100 000 sporulated oocysts of Isospora suis. Fecal samples were examined for oocyst shedding daily and several clinical parameters were recorded. Ten piglets were used as normal controls. Groups of piglets were euthanized from three days to 12 days postinoculation and routine necropsies were performed. Bacteriological, virological, parasitological and histopathological examinations were made on the intestinal tracts. The incubation period was four to five days. Clinical signs and microscopic intestinal lesions observed in the experimentally infected animals were similar to those reported in spontaneous cases of porcine neonatal coccidiosis. Lesions of villous atrophy in the small intestine seemed to result from the destruction of villous epithelial cells mainly during the peak of asexual reproduction which occurred around four to five days postinoculation. Intracellular coccidial organisms were difficult to find during the late atrophic and villous regrowth stages of the intestinal lesions. The prepatent period varied from four to seven days and the most common was five days. Eighty percent of the piglets kept alive more than four days postinoculation have shed oocysts. Piglets dosed with old sporulated oocysts (ten months old) shed many more oocysts than those infected with a fresh inoculum (less than two months old). The patent period was not determined precisely with the design of the experiment but some of the infected piglets shed oocysts for at least five days.  相似文献

Geographical cline of DNA variation within the F intersterility group of Heterobasidion annosum in Italy     

N. LA PORTA  P. CAPRETTI  K. KAMMIOVIRTA  R. KARJALAINEN  & K. KORHONEN 《Plant pathology》1997,46(5):773-784

Eighty-six Heterobasidion annosum isolates, mainly belonging to the F intersterility group and obtained from 32 different geographical localities in Italy, were subjected to genetic analysis by the Random Amplified Polymorphic DNA (RAPD) markers. The similarity between F and S groups was higher than that between F and P. In UPGMA Cluster Analysis, the F isolates originating from the same locality usually grouped in the same cluster. The isolates also showed a tendency to group at the level of larger geographical areas. Within the F group, isolates from the south of the Italian peninsula showed the highest genetic variation and northern isolates from the Alpine regions showed the lowest. This indicates a gradual cline along the peninsula. The genetic variability in the Italian F group is discussed in relation to the past and present distribution of the host species in Italy and Europe.  相似文献

Effect of powdered phosphogypsum on the infiltration rate of sodic soils     

M. Agassi  I. Shainberg  J. Morin 《Irrigation Science》1986,7(1):53-61

Summary Loess and grumusol soils with sodicity levels of 2.5, 6.5 and 17–21 percent were spread over with 3, 5 and 10 t/ha of powdered phosphogypsum (PG) and were rained with distilled water (DW). Phosphogypsum at the rate of 5 t/ha increased the final infiltration rate (FIR) of the loess with ESP of 2.5, 6.5 and 21.0, from 3.0, 1.1 and 0.9 mm/h, respectively in the control to 13.4, 8.5 and 8.3 mm/h, respectively.The final infiltration rate of the same soils with the same ESP levels, rained on with saturated gypsum solutions was lower than that obtained by the PG powder treatment. It was suggested that, besides their effect on the electrolyte concentration of the percolating water, PG particles on the soil surface interfere with the continuity of the crust and may act also as a mulch, and thus increase the IR of the soil.Contribution from the Agricultural Research Organization, The Volcani Center, Bet Dagan, Israel.
