ikan yang dimakan (Geraci et al. 1966; Quinn et al. 2002). EPA (1998) melaporkan B.thuringiensis tidak menunjukkan patogenitas pada hewan laut dan muara, sedangkan pada intervertebrata air menunjukkan toksisitas yang tinggi.
SIMPULAN DAN SARAN
Simpulan
Berdasarkan hasil penelitian telah diidentifikasi 14 genus bakteri, terdiri dari 12 spesies bakteri Gram negatif dan 7 spesies bakteri Gram positif dari saluran pencernaan T. aduncus yang berada di kawasan konservasi lumba-lumba PT. Wersut Seguni Indonesia, Pantai Cahaya, Kendal, Jawa Tengah. Bakteri yang paling banyak ditemukan dalam saluran pencernaan T. aduncus adalah Serratia
sp. ditemukan pada 10 ekor lumba-lumba dan A. faecalis pada 5 ekor lumba- lumba. Serratia sp. dan A. faecalis diduga merupakan flora normal saluran pencernaan T. aduncus.
Saran
Perlu dilakukan uji lebih lanjut untuk mengidentifikasi bakteri sampai tingkat spesies dengan memperbanyak jenis uji biokimiawi dan atau menggunakan polymerase chain reaction (PCR). Selain itu perlu penelitian lain untuk mengidentifikasi mikroorganisme selain bakteri yang hidup dalam saluran pencernaan T. aduncus atau organ yang lain.
