A vaccine for porcine pleuropneumonia caused by Actinobacillus pleuropneumoniae was studied in Croatia on a farm infected by agent serotypes 2 and 9. Vaccination with a commercial subunit vaccine was initiated in the second half of 1998 due to the immense economic damage caused on the farm by this disease. All prefattening and fattening pigs kept on the farm during the first three months of 1999 were allocated in two groups: vaccinated and control. In the control and vaccinated group, 226 and 35 animals (5.78% and 0.96% of the average number of prefattening and fattening pigs in control and vaccinated group), respectively, died from pleuropneumonia....

Rabies antibodies in canine sera were detected and quantified by methods: virus neutralisation test on mice (VNT), rapid fluorescence focus inhibition test (RFFIT), and fluorescent antibody virus neutralisation (FAVN). The results of rabies antibodies levels in non-vaccinated dogs obtained by all three methods were in correlation. The comparison of rabies antibody titres determined in vaccinated dogs using VNT and FAVN methods showed 86.6% correspondence, while those obtained by RFFIT and FAVN methods corresponded in almost 95% of cases.

A complex survey has been conducted in the northern Adriatic Sea over a period of one year that included comparative parasitological, bacteriological, virological, histological and biochemical studies of the cultured and wild sea bass (Dicentrarchus labrax L.). The results show that parasite infestations were due mainly to ectoparasitic monogenea Diplectanum sp. in both cultured and wild sea bass. Philometra sp. and Lernaea sp. were detected in wild sea bass while Triaenophorus sp. and Eimeria sp. were found in reared sea bass. Bacterial pathogens isolated from both reared and wild sea bass belong...

Psychrotrophic vs. total bacterial counts in bulk milk samples

Vet Med - Czech, 2002, 47(8):227-233 | DOI: 10.17221/5829-VETMED  

The objective of the study was to determine psychrotrophic bacteria counts (PBC) and total bacterial counts (TBC) in bulk milk samples collected during a longer period (1999 to 2000). Two sets of samples were analysed. Set 1, including samples collected in three herds, was analysed by the Central Laboratory at České Budějovice. TBC was determined using the apparatus Bactoscan, and PBC by culture according to IDF standards. Relative index pi expressing the PBC/TBC ratio was calculated for each sample. The value of pi for Set 1 was 0.09, ranging in herds included in this set from 0.05 to 0.20. The correlation between PBC and TBC was highly significant...

Haemorrhagic septicaemia, its significance, prevention and control in Asia

Haemorrhagic septicaemia (HS) is an endemic disease in most countries of Asia and sub-Saharan Africa. Within the Asian Region, countries can be classified into three categories, on the basis of incidence and distribution of the disease; these are respectively countries where the disease is endemic or sporadic, clinically suspected but not confirmed, or free. Economic losses due to HS are not only confined to losses to the animal industry, but also rice production on account of its high prevalence among draught animals used in rice fields. Only a few attempts have been made to estimate economic losses, the methodologies used in different countries have...
