Abstract

The aim of this study was to isolate and identify the strain of methicillin-resistant Staphylococcus aureus (MRSA) from cow’s milk in Surabaya and to determine the fragment Spa-Gene in MRSA strains. There were 50 samples of cow’s milk obtained from four dairy farms. From 50 tested samples, 19 samples (38%) were positive for Staphylococcus aureus. Antibiotic sensitivity test using oxacillin and erythromycin showed that 6 samples were resistant to the antibiotic oxacillin and 6 samples were resistant to erythromycin. MRSA confirmation tests that were conducted on 6 samples revealed 5 positive results for the MRSA strain. Electrophoresis of Polymerase Chain Reaction (PCR) product showed that 4 out of 5 samples were positive for the presence of the Spa-Gene fragment. The research results showed that there were 3 models of Spa-Gene fragments; the first had a length of 90 bp and 140 bp, the second had a length of 140 bp, and third had a length of 90 bp. This study revealed the nature of Spa-Gene polymorphism of MRSA strains isolated from milk samples. It was concluded that the Spa-Gene can be used as a molecular epidemiological marker of the MRSA strain.

Abstract

The aim of this research was to evaluate the effect of chayote (Sechium edule) leaves infusion on hemoglobin and hematocrit level of anemic rat (Rattus norvegicus). Twelve anemic hemorrhagic male rats strain Wistar with body weight ranging from 175-200 g were used as sample in this research. Rats were divided randomly into 3 treatment groups, each group consist of 4 rats. The control group (P0) was not given chayote leaves infusion. Group P1 and P2 were given chayote leaves infusion with the concentration of 25% and 50% respectively, with dose of 1 ml per 200 gram body weight. Rats were fed with standard commercial food (Turbo feed) and aquadest ad libitum. The rats were treated anemic by taking 20% blood from total blood volume prior to administration of chayote laeves infusion. Chayote leaves infusion was given for 10 days consecutively. Blood sampling was carried out on day 0, 5, and 10 via caudal vein. Data were analyzed using anlysis of variance (ANOVA) Split-Plot pattern. The result showed that chayote leaves infusion increase level of hemoglobin and hematocrit in experimental rats. In conclusion 25% concentration of chayote leaves infusion is more effective than 50% concentration.Key words: anemia, chayote leaves, hemoglobin, hematocrit
