Abstract

The present study investigated the level of Bacillus anthracis (B. anthracis) spores contamination in the soil, as well as in small ruminant’s wool/hair in Tharparkar, Pakistan. A total of 160 samples, including soil (n= 80), sheep wool (n= 40) and goat hair (n= 40) were collected from different areas of Tharparkar. Results showed that almost 33.75% samples were found positive for B. anthracis spores from soil, wool and hair; among those 66.25% were from outbreak area, having significantly higher (P < 0.001) incidence than normal areas. Moreover, the soil samples exhibited higher positive prevalence (P < 0.001) than  wool, which also had significantly higher (P < 0.001) than hair samples. The samples taken from Mithi area exhibited higher (P< 0.001) prevalence of B. anthracis, followed by Chachro, Diplo and Nangar Parkar (60.00, 30.00, 25.00 and 20.00%, respectively). The differences in area-wise prevalence were also significant ((P < 0.05). The highest prevalence of B. anthracis spores was recorded in open area, followed by in earthen boundaries, and in confined houses (46.42, 30.76 and 23.00%, respectively). These results indicated that soil is a main source of B. anthracis spores, moreover, sheep wool harbor more spores than goat hair.
