Research on Mycobacterium avium during the period 1995 to 2009

M. Kaevska, K. Hruska

Vet Med - Czech, 2010, 55(10):473-482 | DOI: 10.17221/2942-VETMED  

Papers on Mycobacterium avium, published between 1995 and 2009 that are indexed in the databases Web of Science^® (Thomson Reuters) and PubMed (U.S. National Library of Medicine) were analysed and 3377 papers, published by 11 197 authors from 2630 institution and 75 countries were compared. Mycobacterium avium is represented by four subspecies (M. avium subsp. avium, M. avium subsp. silvaticum, M. avium subsp. hominissuis, and M. avium subsp. paratuberculosis). Mycobacteria play an important role as human and animal pathogens and represent a potential risk to consumers...

From research to farm: ex ante evaluation of strategic deworming in pig finishing

This paper upgrades generic and partial information from parasitological research for farm-specific decision support, using two methods from managerial sciences: partial budgeting and frontier analysis. The analysis focuses on strategic deworming in pig finishing and assesses both effects on economic performance and nutrient efficiency. The application of partial budgeting and frontier analysis is based on a production-theoretical system analysis which is necessary to integrate parasitological research results to assess aggregate economic and environmental impacts. Results show that both statistically significant and insignificant parasitological research...

Effects of probiotic dietary supplementation on diarrhoea patterns, faecal microbiota and performance of early weaned calves

J. Jatkauskas, V. Vrotniakiene

Vet Med - Czech, 2010, 55(10):494-503 | DOI: 10.17221/2939-VETMED  

Twenty Lithuanian Black-and-White calves (10 bulls, 10 heifers) were used to evaluate the effects of the supplemental probiotic product, Enterococcus faecium M74 (2.4 g/day/calve), added to fresh milk and skimmed milk in a 56 day-study. The probiotic was administered by dietary supplementation to first group of calves and their respective pens (probiotic group), whereas the second group (control group) received no probiotic supplementation. The results of this trial indicate positive effects of the probiotic product Enterococcus faecium M74. The actual percentage of calves with diarrhoea was reduced from 50 % to 20% among the calves...

Bacterial contamination of the uterus in cows with various clinical types of metritis and endometritis and use of hydrogen peroxide for intrauterine treatment

R. Dolezel, T. Palenik, S. Cech, L. Kohoutova, M. Vyskocil

Vet Med - Czech, 2010, 55(10):504-511 | DOI: 10.17221/2938-VETMED  

The relationship of various clinical forms of uterine inflammation to bacterial contamination and the applicability of hydrogen peroxide for intrauterine treatment of clinical endometritis was the subject of this trial. Uterine contamination was compared among groups of cows according to clinical findings on days 10 ± 3 (mild or severe puerperal metritis and controls without symptoms of the disease: MM, n = 16 or SM, n = 8 and CM, n = 13) and 25 ± 3 (mild or severe clinical endometritis and controls without symptoms of the disease: ME, n = 28 or SE, n = 40 and CE, n = 10). The applicability...

Assessment of transcript and protein levels contributing to cell cycle control and gap junction connections in morphologically variable groups of porcine cumulus-oocyte complexes

P. Antosik, B. Kempisty, M. Jackowska, H. Piotrowska, D. Bukowska, M. Wozna, M. Lianeri, K.-P. Brussow, J.M. Jaskowski

Vet Med - Czech, 2010, 55(10):512-521 | DOI: 10.17221/2941-VETMED  

Oocytes and somatic cumulus cells are connected by an extensive network of gap junctions. These connections contribute in a major way to oocyte maturation and developmental competence. Cumulus-oocyte complexes (COCs) were cultured in standard porcine IVM culture medium (TCM 199) for 44 h. The morphological classification of COCs is based on the number of cumulus cell layers and the degree of their compaction, as well as on cytoplasm composition (homogenous, heterogeneous). The obtained COCs were divided into four grades according to this classification system. By assessing the activity of glucose-6-phosphate dehydrogenase (G6PDH) using the brilliant...
