1 MOLECULAR IDENTICATION AND CLONAL RELATION OF ATYPICAL ISOLATE Aeromonas salmonicida USE METHOD OF RESTRICTION FRAGMENT LENGTH POLYMORPHISM ( RFLP) PRIYATNA, R. 1.), INDARYULIANTO, S. 1.), KURNIASIH 1.), AND ISNANSETYO, A 2.) 1.) Faculty Of Animal Medicinine University of Gadjah Mada-Yogyakarta 2.) Faculty Of Agriculture-Fishery Majors of University of Gadjah Mada-Yogyakarta ABSTRACT Aeromonas salmonicida represent bacterium cause of furunculosis at fish resulting loss of economics in freshwater aquaculture. Counted 4 (four) A. salmonicida isolates have succeeded isolation of fish in 4 (four) region in Indonesia, but not yet been known its clonal relation. At this research to A. salmonicida isolates and ATCC atypical isolate as control have been checked its clonal relation use method of Restriction Fragment Length Polymorphism ( RFLP) by using restrictation enzyme of AluI, HaeIII, MboI and NarI. Result at examination with RFLP at phase I show the existence of difference of band of DNA at isolate 4 while 1, 2, 3 and 5 isolate showing is same pattern, goodness by using enzyme of AluI and HaeIII. Pattern of RFLP that happened is second of primary (15S and also M5) ranging from bp where in all isolates (1, 2, 3, 4 and 5). Location difference of band at isolate 4 more which emerge band in enzyme of AluI on course S rdna A. salmonicida gene compared to HaeIII endonucleus which only cutting 3 multiply in 16S rdna A. salmonicida gene. At phase test II by using of MboI and NarI enzyme where atypical isolate of A. salmonicida (isolate of 1,2,3,4 and 5) showing result of examination do not show the existence of difference and show strong level is overall of gene sequence of 16S rdna nucleotide where cutting a lot emerge band in enzyme of AluI on course S rdna gene A. salmonicida while HaeIII endonucleus only cutting 3 multiply in 16S rdna gene A. salmonicida Keyword : A. salmonicida, RFLP INTRODUCTION Aeromonas salmonicida represent agent of etiological furunculosis, an disease which attacking many fish and cause of loss of economics in freshwater aquaculture (Mccarthy and Roberts; 1980; O'Brien et al, 1994). Typical and atypical term of A. salmonicida used to differentiate among strain causing furunculosis at fish type of International Seminar Biotechnology OI / 85
2 salmon and of strain causing furunculosis at fish besides fish of salmon (Austin and Austin 1999; Inglis et al., 1993) At attacked fish to be marked with septisemia, losing appetite, weak and hurt of nekrosis and haemorahagik at gill, muscle and intestine (Hiney and Olivier, 1999). This bacterium had also been attributed to disease of hurt/ulcer at carp fish and flat fish and also erithrodermatitis at carp fish (Austin and Austin, 1999). Aeromonas salmonicida represent bacterium of Gram-negatif bipolar, having the character of optional anaerob, motion less, not have spore, do not have capsule, in form of short rod, fairish 1,3-2,0 µ best growth at temperature C(Sakazaki and of Ballows, 1981; Untergasser, 1989; Ingglis et al., 1993; Austin and Austin, 1999). Isolation A. salmonicida can grow in various standard bacterium media used occasionally for example Trypticase Soy Agar (TSA) and Brain Heart Infussion Agar (BHIA) and pregnant nutrient media 0,85 % content salt (Ingglis et al.,., 1993; Austin et al., 1998) By using RFLP of 16S rrna gene, will be obtained by spesific pattern-type for all strain of species A. salmonicida (Borrel et al., 1997; Figueras et al., 2000). Where this method can be used to equip gene amplification method 16S rdna of PCR through usage 2 endonucleus simultan AluI (AGCT), HaeIII, NarI and MboI (GATC) (Borrell et al., 1997). Addition 2 enzyme type of NarI (GGCGCC) and of HaeIII (GGCC) needed to to differentiate gene 16S rdna A. salmonicida, A. encheleia of HG 11 (group hybridization 11) Aeromonas spp. (Figueras et al., 2000) Base of RFLP analysis to pass examination with refer to to identify biochemical characteristic like : dexarboxylase lysine, dexarboxylase ornithin, dihydrolase arginin (L/O/A); hydrolysis esculin bile (BAE); product gas from TSI; Voges-Proskauer test; acid of arabinose, sacrose manitol (A/M/S); acid of D- Rhamnose (LOUVRE); acid of D-Sorbitol (SOR); acid of salicin (SAL); acid of lactose; acid of mannose (MAN); and exploiting of citrate (Borrell et al., 1997). This research is executed by applying molecular method (RFLP) at atypical isolate collected A. salmonicida from some area in Indonesia and as control of isolate International Seminar Biotechnology OI / 86
3 atypical of A. salmonicida subsp. smithia Austin et al. product of Americans Type Culture Collection (ATCC) Number :: MATERIALS AND METHOD 1. Fish Fish Test which utilized in this research is goldfish (Carpio cyprinus) size ± 10 cm counted 500, election of test fish type based of territorial water characteristic which still in spanning influence of patogenisitas A. salmonicida. 2. Isolate A. salmonicida isolate the used from Pontianak /isolate 1 (coming from fish of mas/c. carpio), Semarang/isolate 2 (gurame/o. gouramy), Yogyakarta /isolate 3 (freshwater fish pomfret/ C. macropomum), Jambi/isolate 4 (nila/o. niloticus) and as control/isolate 5 is atipikal isolate A. salmonicida subsp. smithia Austin et al. from Americans Type Culture Collection ( ATCC) Number : RFLP Materials for the examination of RFLP method for example : enzyme of AluI (AGCT), HaeIII (GGCC), MboI and NarI (Boehringer), acetic acid glacial, buffer loading ( what consist of 0,25 % blue bromphenol, 0,25 % cyanol xylene and 30 % glyserol), 4 % gel agarose metaphor (PMC Bioproduct) in 0,5 TBE x (Tris-Borate- Edta) Buffer (Metaphor Agarose Gel in stain by using bromide ethidium 0,5 µg/ml), dh2o, sol I for 100 ml (AgNO3 0,15 gr + 37%), sol II for 100 ml (Na2CO3 : 3 gr + Formaldhehyde 151 ml + sodium thiosulfat 5µl/261 mg/ml where is endconcentration 2 mg/ml) and 8 % polycrylamide gel. 4. Characteritation Characteritationto cause bacterium conducted seen morphology, nature of Gram, motilitas and nature of other cultural like : ability of ferment, IMVIC, and biochemy Examination of bichemistry conducted at all isolate conventionally.

4 RESULT ANN DISSCUSSION 1.Result By virtue of result of research show there is inappropriate of used enzyme at examination with RFLP at phase I where atypical isolate of A. salmonicida from some region in Indonesia and atypical isolate of ATCC show an difference of band at isolate 4 while isolate 1, 2, 3 and 5 showing is same pattern, goodness by using of AluI enzyme (blue colourant)/ 15S primary and HaeIII enzyme (red colourant)/ M5 primary. Pattern of RFLP method that happened is second primary (15S and also M5) ranging from bp where all isolate (1, 2, 3, 4 and 5) emerge band showing do not happened mistake identify isolate. Location difference of band at isolate 4 more which emerge band in enzyme of AluI on course S rdna gene A. salmonicida while HaeIII endonukleus only cutting 3 multiply in 16S gene rdna A. salmonicida (Picture 1). This is matter more caused by technical factor but not of genetica factor or phenotipic factor from all isolate A. salmonicida which is used in this research At phase test II by using of MboI and NarI enzyme where atypical isolate of A. salmonicida (isolate of 1,2,3,4 and 5) showing result of examination of method of RFLP do not show the existence of difference and show strong level is overall of gene sequence of nucleotide 16S rdna where cutting a lot emerge band in enzyme of AluI on course S rdna gene A. salmonicida while HaeIII endonucleus only cutting 3 (three) multiply in 16S rdna gene A. salmonicida. This matter more caused by technical factor but not genetic factor or phenotypic factor from all A. salmonicida isolate which is used in this research. International Seminar Biotechnology OI / 88

Equation genome A. salmonicida strain can be conducted by comparing method of RFLP-PCR among A. salmonicida strain isolate from Indonesian and closely related with isolate of A. salmonicida subsp. smithia of ATCC, where method application application of RFLP method besides can yield pattern able to be pattern able to be grouped in one subspesies able to be grouped in one subspesies (Huys et al., 1997), also by phenotip can clarify gene variation of 16S rrna A. salmonicida subsp. smithia (Graph, 1999). CONCLUSION Thereby, as an conclusion, A. salmonicida atypical isolate from Indonesian represent subspecies smithia, for that can be expressed that method of RFLP-PCR 16S rrna gene can be used in assisting early identifying type of Aeromonas. Verification identify type with biochemical test remain to be conductedbas according to diagnosis of clinical to solve differences that happened REFERENCES Austin, D.
