The One

In the period from January 2001 to December 2005, a total of 6,904 slaughtered cattle originating from the territory of the region of Jablanica were examined at the Mesokombinat AD abattoir. The Trematoda Fasciola hepatica was found in 429 cattle (6.21%). A total of 2,150 kg livers were condemned due to the presence of the liver fluke. A comparison of cattle with bovine fasciolosis according to the years yielded a very significant difference (p<0.01) between the year 2003 (10.02) and the year 2002 (9.97), on the one side, in comparison with the years 2001 (5.14), 2004 (3.37), and 2005 (5.08), on the other side. A significant difference (p<0.05) was also established in the year 2004 (3.37) in comparison with the years 2001 (5.14) and 2005 (5.08). After analyzing the significance of the differences between the infected cattle according to the seasons, a very significant difference (p<0.01) was established between the summer (7.23) and the winter (4.74) periods. A significant difference (p<0.05) was also established between the autumn (6.49) and the winter periods. The amount of precipitation was directly proportionate to the percentage of cattle infected with fasciolosis.

History Of

The life history of Lymnaea columella was studied under laboratory conditions at Río Piedras, Puerto Rico. The snail matured in 21 to 23 days after hatching, when shell length was 5 to 6 mm. A culture box 27 X 21 X 11 cm. provided adequate space for a colony of 20 adult specimens. A mature snail raised individually produced an average of 20 eggs daily. The incubation period of the eggs at 26° to 28° C. varied from 10 to 13 days with 98 to 100 percent hatchability. Both eggs and adult snails were highly sensitive to desiccation; not so young snails. To test the behavior of L. columella under stress of infection with Fasciola hepatica, adult specimens were exposed to a variable number of miracidia. These were obtained by cultivation of eggs from the gall-bladder of infected cattle. The miracidia hatched in 10 to 13 days at 26° to 28° C. and did not live more than 3 1/2 hours. Snails receiving 2 to 4 miracidia tolerated the infection well with low mortality but died within 2 to 6 days after cercariae started emerging. Specimens receiving four to six miracidia were able to survive but the mortality rate was high. Inocula of 10 to 16 miracidia caused early death of the snail. The cercariae, released from the snail in 57 to 60 days after infection encysted within 15 to 20 minutes to become metacercariae. Mice tolerated infection with one metacercaria; rats, with five metacercariae. Eggs first were observed in feces at 31 and 51 days post-exposure in mice and rats respectively.
