“…Considerable increase in the numbers of cases when bovine carcasses were condemned because of lesions due to paratuberculosis (index 4.62) is alarming. This disease may become a serious problem, as it can be concluded from the papers by Pavlik et al (2000), Ayele et al (2001), and Fischer et al (2001).…”

The results of meat inspection at slaughterhouses with appropriate trends indicate possible risks due to unsafe meat obtained from bovine carcasses at slaughterhouses. Such risks are eliminated by strict veterinary inspection of animals prior to slaughter, as well as of meat and parenchymatous organs a�er slaughter. A specification of slaughterhouse findings and expression of trends in different parameters may indicate in some areas increased risks with regard to certain aspects of food-borne diseases originating from meat and organs of slaughter ca�le, while in other areas the risks may be on the decrease. Long-term trends in the decision-making process in meat inspection classification may serve as an important indicator for the measures to increase food safety.Veterinary inspectors classify bovine carcasses into the categories of capable for human consump- (Period I, 1995-1998, and Period II, 1999-2002 by means of calculating the indexes of values from Period II compared to those of Period I. Bovine carcasses classified as capable for human consumption (edible) were found in 87.87% of cases (88.83% during Period I and 86.58% during Period II, index 0.97), while those classified as capable for processing (conditionally edible) were found in 7.53% of cases (7.38% during Period I and 7.71% during Period II, index 1.04), and those condemned in 4.60% of cases (3.79% during Period I and 5.71% during Period II, index 1.51). The most important reason for classifying the carcasses as condemned was the finding of sensorial changes in meat, which occurred in 2.56% of cases (2.23% during Period I and 3.00% during Period II, index 1.35), followed by lesions due to non-infectious diseases -1.00% (0.81% during Period I and 1.25% during Period II, index 1.53), added deleterious substances -0.88% (0.60% during Period I and 1.27% during Period II, index 2.11), lesions due to respiratory infections -0.03% (0.02% during Period I and 0.04% during Period II, index 1.74), and lesions due to miscellaneous infectious diseases -0.10% (0.10% during Period I and 0.10% during Period II, index 1.05). Other reasons to condemn the carcasses included improper identification, lesions due to digestive infections, lesions due to tuberculosis, lesions due to paratuberculosis, lesions due to salmonellosis, leucosis and parasitic diseases. The occurrence of these conditions was on the level of mere hundredths of per cent. According to the results of meat inspection classification, the risk of food-borne diseases originating from bovine carcasses tends to be greater in the lesions due to non-infectious conditions with a long-term increasing trend. A considerable increase in the numbers of bovine carcasses condemned because of lesions due to paratuberculosis (index 4.62) represents an alarming finding with regard to potential food safety hazards.

“…The most susceptible are calves during the first weeks of their life. Evidence of pathogens was found not only in the intestine but also in milk, lymph nodes, and different parenchymatous organs (Pavlik et al, 2000;Ayele et al, 2004). Confirmed MAP isolates were cultured from 1.8% of the commercially pasteurized milk samples in the U.K. (Grant et al, 2002).…”

Fifty one products of dried milk baby food purchased from 10 producers from seven countries available on the Czech market have been tested. IS900, the specific fragments for Mycobacterium avium subsp. paratuberculosis (MAP) have been detected using PCR in 25 samples (49.0 %) and fragment f57 by real time PCR in 18 samples (35.3%). These results correspond to the epidemiological situation in Europe and are not unexpected. Paratuberculosis in cattle was almost unknown in the Czech Republic until 1990. An increase in the number of cows with paratuberculosis found in slaughterhouses and the incidence of Crohn's disease in the last decade is evident. The possible risk of MAP dead cells or bacterial structures in food is discussed in respect to autoimmune Crohn's disease. The national programmes of paratuberculosis control and certification of paratuberculosis-free herds should be strongly supported to decrease the risk for children and other people under higher risk. Producers should use MAP free milk for baby food production on a voluntary basis.

“…Não existe um teste de referência que permita a detecção de todos os animais infectados. Tradicionalmente, no diagnóstico da infecção ovina, recorre-se a testes serológicos combinados com o exame clínico e o exame bacteriológico das fezes (Hilbink et al 1994, Clarke et al 1996, Collins 1996, Pavlík et al 2000. A cultura foi positiva em 2,0% das 300 amostras cultivadas.…”

Comparação de duas técnicas de isolamento do Mycobacterium avium subsp. paratuberculosis em amostras de fezes de ovinos com suspeita clínica de paratuberculose

A paratuberculose é uma enterite crônica granulomatosa causada por Mycobacterium avium subsp. paratuberculosis que afeta principalmente os ruminantes. A cultura de bactérias a partir de amostras de fezes e tecidos constitui um dos métodos mais eficazes de diagnóstico, sendo ainda o único método disponível para obtenção de isolamentos e estirpes de micobactérias. Contudo, este método apresenta baixa sensibilidade e requer meses de incubação antes do crescimento de colônias. Neste estudo, utilizou-se a cultura fecal como método de diagnóstico em ovinos de diferentes raças portuguesas, com sinais compatíveis com a doença. Fez-se ainda a comparação entre os meios de cultura Löwenstein Jensen® com micobactina® J e o de Middlebrook® 7H11 com OADC®, utilizados no isolamento da bactéria. As percentagens de isolamento em cada um os meios foram de 2,0% (6/300) para Löwenstein Jensen® com micobactina J e 1,0% (3/300) para Middlebrook® 7H11/OADC. As três amostras positivas no meio de Middlebrook® 7H11/OADC também foram positivas no meio de Löwenstein Jensen® com micobactina J e nenhuma foi somente positiva no meio de Middlebrook® 7H11/OADC. Os resultados deste estudo sugerem que o meio de Löwenstein-Jensen® com micobactina® J é mais efetivo para a obtenção de estirpes ovinas em Portugal.
