Effect of Bathing in a 0.1% Aqueous Solution of Ethacridine Lactate on Selected Physiological Parameters of Müller Edible Snails.

INTRODUCTION

The prohibition of antibiotic use in edible snails obligates breeders to treat bacterial infections by different means, of which a common one is a bath in Gram-positive- and partially Gram-negative-bactericidal ethacridine lactate solution. The aim of the study was to determine the effect of bathing Müller snails in a 0.1% aqueous solution of ethacridine lactate on selected physiological parameters of haemolymph.

MATERIAL AND METHODS

The study included 80 snails, divided into two equal groups (study and control). The study group was subjected to bathing in ethacridine lactate and the control group to bathing in tap water. Both groups were treated daily for seven days. The number of haemocytes in the haemolymph, the activity of alanine (ALT) and aspartate (AST) aminotransferases, and the concentration of urea were determined.

RESULTS

In the study group, after exposure to ethacridine lactate solution an increase in ALT activity, changes in the De Ritis ratio, an increase in the amount of haemocytes, and a decrease in body weight were found. No such changes were detected in the control group snails or in animals after the first bath.

CONCLUSION

Multiple applications of a 0.1% ethacridine lactate bath may adversely affect Müller snails.
