2009
Moshtaghi, H. | Garg, S. R. | Mandokhot, Usha V.
Survivability of Listeria monocytogenes in clay loam soil was examined at 30° C for a period of 35 days. The microorganism inoculated in soil steadily declined from 3.5 × 10 6 g -1 to 3.9 × 10 4 g -1 (P = 0.05) on 35 th days. Destruction of normal soil microflora by heat treatment resulted in marginal rise in 3.3 × 10 6 g -1 of L. monocytogenes to 4.2 × 10 6 g -1 during the first 7 days, followed by steady decline to 5.6 × 10 4 g -1 on 35 th days. Heat treated soil inoculated with lower concentration of L. monocytogenes (3.6 × 10 4 g -1 ) supported sharp rise in its population to 4.8 × 10 6 g -1 (P=0.05) during the first weak which gradually declined, but remained higher (6.1 × 10 4 g -1 ) than the initial load even on 35 th days. In non-sterile soil, the rise was less appreciable but L. monocytogenes maintained its levels (10 4 g -1 ) during the experimental period. Survivability of the microorganisms was also observed in the soil with added chicken manure, cattle manure or sheep/goat manure.

Bano, Siddiqua | Prakash, Ved
Filix-mas a homeopathic drug consisting etherieal extract of male fern is used to remove the tape worms. The drug was tested for Moniezia expensa infection in sheep. Ten sheep naturally affected Moniezia expansa were used. Filix-mas 200 (10 _ 15 drops) was given three times a day orally to animals of the group A, while the sheep group B were kept as untreated control. Efficacy of the drug was observed by calculating faecal egg count reduction. It was found that Filix-mas could cure 100% monieziosis in sheep.
