Abstract

This study was carried out to determine the occurrence of bacteria and fungi in populations of turkey and duck faeces. The prevalence of bacteria and fungi in the faeces of domesticated turkey and ducks (Meleagris ocellata and Anas platyrhynchos) in the City of Akure (Nigeria) was investigated. Five different locations were sampled in Akure Metropolis in April for each of turkey and duck faeces using standard microbiological methods. The microbial load for bacteria ranged from 16.23 × 105 to 30.04 × 105 cfu/g and 12.60 × 105 to 46.01 × 105 cfu/g for turkey and duck faeces respectively while the fungal count ranged from 12.38 × 105 to 28.05 × 105 s/g and 10.60 × 105 to 34.09 × 105 s/g for turkey and duck faeces respectively. The following bacteria were isolated from turkey faeces: Azomonas agilis, Bacillus cereus, Escherichia coli, Proteus vulgaris, Sarcina maxima, Thiocapsa lumicola, Staphylococcus aureus, Enterococcus spp., Xanthomonas fragariae and Streptococcus spp. while Aeromonas hydrophila, Bacillus cereus, Echerichia coli, Proteus vulgaris, Lactobacillus spp., Sarcina maxima, Streptobacillus moniliformis, Staphylococcus aureus, Enterococcus spp and Streptococcus spp. were isolated from duck faces. Bacteria common to both turkey and duck faeces are Bacillus cereus, Escherichia coli, Proteus vulgaris, Sarcina maxima, Staphylococcus aureus, Enterococcus spp. and Streptococcus spp. The fungal species isolated includes Mucor spp., Cladosporium spp., Aspergillus fumigatus and Aspergillus flavus, Alternaria sp., Candida spp., Fusarium spp., Varicosporium elodea and Penicillium spp. Some of the isolated microorganisms are of major importance in the natural environment as well as food and drug production. It could be concluded that turkey and duck faeces are a potential human health hazard and that accumulation of their droppings may pose a public health risk and can cause illness.

Highlights

  • A turkey is either of two or three living species of large birds in the genus Meleagris

  • The bacterial population isolated from turkey and duck faeces showed a range of 16.33 to 30.00 × 105 cfu/g and 12.67 to 46.00 × 105 cfu/g respectively while the fungal population mean values were 21.8 cfu/spore and 21.2 cfu/spore for duck and turkey faeces respectively

  • Bacterial colony count was done to determine the total number of microorganisms present in the duck and turkey faecal samples collected

Summary

Introduction

A turkey is either of two or three living species of large birds in the genus Meleagris. Meleagris gallopavo, commonly known as the Wild Turkey, is native to the forests of North America. The other species, Meleagris ocellata, known as the Ocellated Turkey, is native to the forests of the Yucatán Peninsula. Duck is the common name for a number of species in the Anatidae family of birds. The ducks are divided between several subfamilies in the Anatidae family; they do not represent a monophyletic group but a form taxon, since swans and geese are not considered ducks. Ducks are mostly aquatic birds, mostly smaller than the swans and geese, and may be found in both fresh water and sea water (The American Heritage Dictionary of the English Language [2])
