Introduction

Toads (Bufo species) are amphibians, known to alternate between the aquatic and terrestrial habitats. They live in close proximity with humans, especially during the rainy seasons. They are eaten as delicacies in some parts of the world. Children hunt them and play with them. However, toads are reservoirs of zoonotic infections and could transmit some bacteria to humans through environmental pollution of water source. They could also compromise food safety through cross-contamination during food handling. Enteric bacteria infection are a public health challenge because of the interaction between the environment, human health and animal health as depicted by the one health model. This study aim to identify the bacteria flora of toads gut and to create an awareness on the need for safety awareness in order to interrupt the enteric bacteria transmission to humans.

Methods

Toads were collected and put in aerated cylinders and transferred to the laboratory. The toads were anaesthezed with chloroform in desiccators for twenty minutes and were rinsed with distilled water. They were pinned down on a dissecting board to expose their ventral surface which was swabbed with alcohol. Dissection was done with sterile scissors and forceps, and the gut was removed aseptically. The gut regions were cut open with a sterile scalpel.  Inocuum was collected from the esophagus, stomach, small-intestine and streaked onto culture media (Nutrient, Mac Conkey agar) while rectum inoculm was streaked on Deoxycholate agar. The plates were incubated. The isolated bacteria were characterized and analyzed.

Results

Staphylococcus aureus, Escherichia coli, Klebsiella species, Proteus species and Salmonella species were isolated with percentage of total occurrence of 17.3%, 24.6%, 26.3%, 24.0% and 7.7% respectively. The occurrence of each bacteria species is lowest in the stomach region.

Conclusion

Enteric bacteria of toads reflect the environmental hygiene and pose  public health risk to humans.
