RESUMEN
Campylobacteriosis is a leading cause of zoonotic diarrhoea in the developed as well as developing countries. Domestic animals particularly the poultry act as a source of human infections. Domestic animal rearing is a very common practice in India particularly in rural areas. The present study of KAP of Zoonosis showed 68.2 % of 500 families interviewed did not have knowledge about zoonotic diseases in rural Bengal and not a single family had any idea of Campylobacter infections.

The electron paramagnetic resonance linewidth of aquo gadolinium(III) ion changes with the counter-ion identity and concentration in aqueous solutions. The EPR linewidth of 2 mM gadolinium(III) chloride increases from 49.2 to 89.0 mT when carbonate ion is added and decreases to 17.3 mT when nitrite ion is added. These observations suggest association reactions between aquo gadolinium(III) ion and anions that change the electron spin relaxation rates of the aquo ion. The concentration dependence of the gadolinium(III) EPR linewidth is consistent with binding constants for nitrite and nitrate ion with the aquo gadolinium(III) ion of 37 +/- 6 and 2.3 +/- 0.3 L mol-1 respectively. The decreases in the EPR linewidth factors with these association reactions are difficult to understand unless the anion reactions increase the symmetry of the metal center. Although first-coordination reactions may not be ruled out, the decrease in EPR linewidth is more consistent with an outer-sphere association reaction that also reduces the coordination number of the metal center from 9 to 8.
