ABSTRACT

The presence of coliforms bacteria is one of the most prevalent problems in terms of public health in marine ecosystems over the world. In this study were investigated the physico-chemical properties of seawater and the numbers of total aerobic, total coliform, fecal coliform, E. coli O157:H7 and fecal streptococci in seawater and mussel samples collected from Sinop environs between May and October 2011. The microbiological analysis of seawater samples showed that the difference between total coliform, fecal coliform and fecal streptococci numbers (p<0.05) was significant for each station. However, the difference among total aerobic bacteria numbers for each stations (p>0.05) were not found significant. The difference between whole counting results for mussel samples taken from different sampling sites was not significant (p>0.05), too. Furthermore, the results of the screening assay for the presence of E. coli O157:H7 showed that the strain was not detected in neither seawater nor mussel samples. In conclusion, it was determined that fecal coliform and fecal streptococci counts in the seawater and mussel samples were higher than legal (Turkish Bathing Water and Quality of Fishery Products Regulation) limit values for some stations in Sinop coastal areas.

Keywords: E. coli and E. coli O157:H7; fecal indicator bacteria; mussels; seawater

ABSTRAK

Kehadiran bakteria koliform adalah salah satu masalah yang ketara daripada segi kesihatan awam dalam ekosistem marin dunia. Dalam kajian ini, kami mengkaji sifat fisiko-kimia air laut dan jumlah aerobik, jumlah koliform, koliform tahi, E. coli O157:H7 dan tahi streptococci dalam sampel air laut dan kupang yang dikumpul dari kawasan Sinop antara Mei dan Oktober 2011. Analisis mikrob ke atas sampel air laut menunjukkan bahawa perbezaan antara jumlah koliform, koliform tahi dan streptococci tahi (p<0.05) adalah bererti bagi setiap stesen. Walau bagaimanapun, perbezaan antara jumlah bakteria aerobik bagi setiap stesen (p>0.05) didapati tidak bererti. Perbezaan antara keputusan pengiraan keseluruhan sampel kupang yang diambil dari kawasan persampelan berbeza juga tidak signifikan (p>0.05). Selain itu, keputusan saringan asai untuk kehadiran E. coli O157:H7 menunjukkan bahawa tekanan tidak dapat dikesan dalam sampel air laut mahupun kupang. Kesimpulannya, dapat ditentukan bahawa kiraan koliform tahi dan streptococci tahi dalam sampel air laut dan kupang adalah lebih tinggi daripada had nilai yang dibenarkan (Peraturan Air Mandian serta Kualiti Produk Perikanan Turki) bagi sesetengah stesen di kawasan persisiran pantai Sinop.
