THORACIC RADIOGRAPHY OF FOALS. LITERATURE REVIEW

Thoracic radiography is commonly used in case of differential diagnosis of respiratory or other thoracic diseases. To perform it a correctly positioned and good quality image is basic for further evaluation. The position of the animal, the phase of respiration, the focus direction, the used exposition values, films and grids all influence the image quality. The radiographic signs of the different respiratory diseases are non-specific which means that different thoracic alterations can result in similar radiographic changes and the same thoracic alteration can lead to different radiographic appearance. The subjectivity of the observer, which is supported by experience, also plays an important role in the evaluation. The authors review the literature of the thoracic radiography of foals. The technique of the radiography and the criteria of the image evaluation is summarized and some typical alterations and pattern types are described with the help of clinical cases and corresponding images.

EFFICACY OF DIFFERENT ANTIMICROBIAL THERAPEUTIC PROTOCOLS FOR THE TREATMENT OF PUERPERAL METRITIS AND ENDOMETRITIS IN DAIRY COWS

Four field trials were carried out on large-scale dairy farms in Hungary to assess the efficacy of different therapeutic protocols in terms of reproduction performance for the treatment of puerperal metritis (PM) and clinical endometritis (EM).
For the PM therapy (Table 1), oxitetracycline (OTC), amoxicillin (AMO) and gentamycin (GEN) products were used in intrauterine (IU) route, which were supported by parenteral (im.) application of the same antibiotics for the cows developing systemic, general signs of the disease. A high dose (3 g/day) of OTC treatment proved to be more efficacious than the two other antimicrobials in terms of lower frequency of EM (33% vs. 58% in both), as well as lower incidence of Arcanobacterium pyogenes (A. pyogenes) as primary uterine pathogen (24% vs. 50%). Statistically significant difference were also found in higher fertility rate (69% vs. 42% and 44% respectively) and shorter service period (95±25, 113±29, 116±27 days, respectively).
EM treatment was studied in three different trials, where the following compounds were used: cephapyrin (in 2 trials), penicillin–neomycin (in 1 trial) and inorganic iodine (in 1 trial) used IU, while PGF2α and tylosine applied im. Cephapyrin and tylosin were tested concomitantly with PGF2α, as well. Concerning EM significantly lower proportion of animals became pregnant regardless of treatment among A. pyogenes infected cows than those of A. pyogenes free ones (50% vs. 76%). Marked improvement in fertility rate, as compared to untreated control group was observed mostly after cephapyrin IU treatment (65% vs. 52% and 67% vs. 49% in two trials), but also was demonstrated after tylosin im treatment (68% vs. 55%) and PGF2α (65% vs. 52%; 63% vs. 49% and 67% vs. 55% in three trials) treatment. These differences were statistically significant only, when the data of A. pyogenes carrier cows were analyzed separately. Penicillin–neomycin combination did not show any effect in terms of reproduction performance (53% vs. 52%). Despite its still relatively common use in practice, inorganic iodine had also no effect at all (52% vs. 52%). No further improvement was demonstrated in the cases of concomitant treatment with PGF2α and either cephapyrin or tylosine.
These data proved that in postpartum dairy cows certain antimicrobials represent real value in therapy of bacterial complications of uterine involution, especially in PM, and in cows with A. pyogenes infected uterus. When ingredient is selected, the characteristics of the postpartum uterus, and the microbial feature of the complication should be considered. For the confirmation of real efficacy, however, clinical and microbial findings should be compared with data on re-conception.

EXAMINATION OF SOME EFFECTS ON CONCEPTION OF BEEF BREEDS

Conception results of 9 breeds (Hungarian Fleckvieh, Hereford, Aberdeen Angus, Red Angus, Lincoln Red, Limousin, Charolais, Blonde d’ Aquitaine and Shaver) kept under the same conditions on peat-bog soil pasture at Keszthely were evaluated between 1998 and 2005. The effect of breed, age, date of calving, live weight of cows, absolute and relative weight change of cows during the grazing period, and preweaning daily gain of calves were examined.
Conception rate of different breeds were as follows: Red Angus 82.2%, Charolais 82.0%, Aberdeen Angus 78.9%, Hereford 74.7%, Lincoln Red 71.1%, Shaver 67.2%, Limousin 65,9%, Hungarian Fleckvieh 65,6%, Blonde d’Aquitaine 60,8% (P<0.01). The examined population have the best conception rate in 2001 (90.5%). The effect of age, live weight and preweaning daily gain of calves was not significant on the conception. Cows calving between January and March had better conception results, than those calving in other months (P<0.001). Cows that increased their live weight by 50 kg or 10% during the grazing period had better conception rate, than those that had the same weight or lost their weight (P<0.001).
The conception rate had a correlation with age, date of calving, live weight, live weight change of cows, preweaning daily gain of calves: r = –0.02; –0.40 (P<0.01); 0.02; 0.19 (P<0.01); 0.23 (P<0.01), respectively.

SCRAPIE IN SHEEP 4. PRION GENOTYPE FREQUENCIES IN MOUFLONS AND DOMESTIC HAIR AND SHEDDING WOOL SHEEP

Prion genotypes have been determined in hair and shedding wool sheep, mouflon and mouflon x domestic sheep crosses. Breeding programme has been iniciated to develop a new Hungarian hair sheep breed. Since the frequencies of the resistant prion genotypes in the breeds involved in the crossbreeding programme are very low, continuous prion genotyping will be carried out to attain high frequencies of the resistant genotypes in the new breed.

SYNCHRONOUS ANAPLASTIC MAMMARY GLAND CARCINOMA AND SKIN MASTOCYTOMA IN BOXER DOG. ONCOLOGICAL CASE REPORT

In this study, the authors shortly summarize the histopathological characterisics of the anaplastic tumours and the anaplastic carcinoma of mammary gland, and mast cell tumours in dogs. They describe at the first time in the veterinary oncology the synchronous anaplastic breast carcinoma and grade-I mast cells tumors in a six-year-old, non-castrated female boxer. Applying anti-pancytokeratin and anti-vimentin, the anaplastic tumors cells of the mammary gland showed intensive color reaction, positivity in the cytoplasm, and negativiy in case of anti-myoglobin, and CD-68-antibody. The proliferation index detected with KI-67 marker turned out to be 36% in the examined anaplastic breast cancer. According to these results of the IHC tests, the authors suggest to use as an internal control, the intact epithelial cells of the mammary gland for the cytokeratin, the stromal fibroblasts in the mammary gland for the vimentin, and the striated myofibres for the myoglobin during the evaluation of the IHC results of tumour samples from canine mammary glands.

EPIZOOTIOLOGICAL AND SEROLOGICAL SURVEY OF FELINE AIDS, LEUKAEMIA AND TOXOPLASMOSIS IN DOMESTIC CATS POPULATIONS IN THE SLOVAK REPUBLIC

The aim of this study was a serological survey of two retroviral diseases of domestic cats – feline AIDS and feline leukaemia, and a survey of a protozoan parasitic zoonosis – toxoplasmosis, as well as an epizootiological and epidemiological evaluation of the results of this survey. 164 stray cats and cats caught on the territory of the Slovak Republic were subjected to serological examination in 2004 and 2005; one of them was infected with feline AIDS, and another with feline leukaemia (0.61%). Toxoplasmosis was found in 31 cats, i. e. in 18.9% of the examined animals.
