Interrelationship of feeding with immunity and parasitic infection: a review

S.Gy. Fekete, R.O. Kellems

Vet Med - Czech, 2007, 52(4):131-143 | DOI: 10.17221/2028-VETMED  

Authors overlook the recent findings in the field of the complex interrelationship among nutrition, immune status and parasitic infestation. After summarizing the general characteristics of the active immune system, they describe the first period of the systemic immune response, the acute phase reaction. The cause of drastical decrease in serum zinc concentration is redistribution into the liver and lymphocyte metallothioneins. Immune deficiency correlates only indirectly with the nutrition. Ingestion of feed mycotoxins (e.g. T-2 toxin) and peroxides causes lymphocytes depletion in the lymphoid organs. Events of immunological stress are a special form...

Vet Med - Czech, 2007, 52(4):144-161 | DOI: 10.17221/2032-VETMED  

The present study describes pathogenesis and morphology of tuberculous and tuberculoid lesions in small terrestrial mammals, above all, in rodents. The most serious infectious agents that cause tuberculous and tuberculoid lesions in these animals are also cited. Besides others, the diseases caused by pathogenic mycobacteria that are members of Mycobacterium tuberculosis and M. avium complexes, M. lepraemurium, tularaemia, brucellosis and salmonellosis are included in the present study.

Forty randomly selected chickens were allocated into four groups: K, HA, Cd and Cd + HA. After a 5-day adaptation period, the experiment was initiated. Group K was fed a diet without supplements. Group HA was fed the same diet with a 0.5 g supplement of humic acid per chicken/day. Group Cd was treated with 0.147 mg Cd per chicken/day (0.3 mg of CdCl₂ . 5H₂O), and Group Cd + HA was given the same treatment as the latter group, with an additional 0.5 g humic acid per chicken/day. The chickens were given the above mentioned treatment daily, for 10 days. Subsequently, they were slaughtered and samples from livers, kidneys and leg...

Comparison of methods for the determination of antimicrobial resistance in Campylobacter spp. human and the food chain isolates

M. Holasova, R. Karpiskova, S. Karpiskova, V. Babak, J. Schlegelova

Vet Med - Czech, 2007, 52(4):169-174 | DOI: 10.17221/2030-VETMED  

With a microdilution method, using the commercial diagnostic test Sensititre Susceptibility Plates for Campylobacter MIC (Trek Diagnostic Systems, Cleveland, OH, USA), disk diffusion and agar dilution method, resistance to six antimicrobial agents were examined in a reference strain Campylobacter jejuni ATCC 33560 and 73 thermo-tolerant isolates of Campylobacter spp. For the microdilution method and all tested antimicrobial agents, our determined values of microbiological breakpoints of resistant strains were suggested as the minimum inhibitory concentration (MIC_R) for ciprofloxacin ≥ 0.5, erythromycin ≥ 4, gentamicin...

Atlantic bluefin tuna (Thunnus thynnus) farmed in the Adriatic Sea

Vet Med - Czech, 2007, 52(4):175-177 | DOI: 10.17221/2029-VETMED  

Levels of total mercury in the muscle (29 samples) and liver tissue (15 samples) of bluefin tuna (Thunnus thynnus) weighing 100-300 kg were determined by cold vapour atomic absorption (AA) spectroscopy. Tunas were previously captured in the waters of Malta, towed to the farm in the Adriatic Sea and fattened with defrosted herring and sardine for the period of 6 to 7 months. The purpose of the investigation was to determine the magnitude of mercury contamination and to ascertain whether the concentrations in muscle tissue exceeded the maximum level defined by the European Commission Decision (1 μg/g wet weight). Total mercury concentrations...
