Abstract
Streptococcus sp is Gram positive cocci and aligned like chain. This bacteria can be found normally in upper respiratory tract. Streptococcus sp can be divided into two groups; able to hemolize blood and unable. B-hemolytic Streptococcus tend to be more pathogen than the others. Therefore this research about Streptococcus sp’s hemolysis profile is very important. The samples of this research is an isolated swine nasal swab from a traditional pig farm in Bongkasa Village. 20 samples were used in this research. Samples were grown in Blood Agar media to find out the capability of bacteria for hemolizing blood. Catalase test used for differentiating Streptococcus sp and Staphylococcus sp, followed by oxydase test after. Result of the research shows positive samples of Streptococcus sp divided by hemolysis profile is 11 isolates whereas 36,4% isolates were Alfa hemolysis, 54,6% were B hemolysis, and 9% isolates were Gamma hemolysis.
Highlights
Pigs are potential livestock animals to be bred with the aim of fulfilling the needs of animal protein in Indonesia
Bacterial isolation is carried out by means of samples taken from the field planted in blood media so that it is incubated at 37 ° C for 24-48 hours in an anaerobic atmosphere with 5-7% CO2 [7]
20 samples of swine nasal cavity swabs were isolated in Blood Agar media to grow bacteria
Summary
Pigs are potential livestock animals to be bred with the aim of fulfilling the needs of animal protein in Indonesia. Pigs are one of the livestock commodities that have great potential to be developed because they have their own advantages, including fast growth rates, many litter sizes and are quite efficient in using rations [2]. Streptococcus sp is a Grampositive bacterium in the form of coccus and arranged in chains. These bacteria ferment carbohydrates, nonmotile, do not form spores, and are catalase-negative. Streptococcus sp bacteria are normal flora in the intestinal tract, cervicovaginal area, upper respiratory tract, skin and mucous membranes [4]. Outbreaks of Streptococcus sp in pigs have been reported in Bali from May to July 1994
