Introduction : Extended-spectrum ?-lactamase (ESBL) is a mutated ?-lactamase enzyme that can hydrolyze beta-lactam antibiotics. The aim of this study was to determine the incidence rate, characteristics of patients, antibiotic use and outcome of urinary tract infections (UTIs) due to ESBL-producing Escherichia coli and Klebsiella pneumoniae at Dr Zainoel Abidin General Hospital Aceh.Method : The samples of this study were all Escherichia coli and Klebsiella pneumoniae isolated from urine culture of UTI cases. Patient characteristics and antibiotic use data were extracted from medical records. UTIs outcome was assessed as clinical improvement or death within a maximum of 30 days of treatment.Result : The results of this study obtained 63 patients with UTIs caused by E. coli and K. pneumonia of which 52.4% of them were ESBL producers. The incidence of UTIs due to E. coli was higher than that of K. pneumoniae, 63.5% and 36.5% respectively. E. coli ESBL producers were more in number than non-ESBL, conversely K. pneumoniae were mostly non-ESBL. The characteristics of patients with UTIs caused by E. coli and K. pneumoniae were predominant women 52.4%,  and most cases were at 56-64 years old. Antibiotic therapy that given before and after culture results to UTI patients were generally ceftriaxone. UTIs outcome due to ESBL producing Escherichia coli and Klebsiella pneumoniae showed that 26/33 (78.8%) patients experienced improvement, however, 7/33 (21.2%) patients died.Conclusion : The irrational use of ceftriaxone in patients with UTI caused by ESBL producing E. coli and K. pneumoniae has led to a poor outcome for the patient.

Non-invasive measurement hormones in feces using enzyme immunoassay (EIA) technique needs to be validated. This study was conducted to develop and validate an enzyme immunoassay kit for measuring the concentration of cortisol metabolites in feces of Toraya buffalo. An EIA kit of 11β-hydroxyetiocholanolone (11β-hydroxy-CM assay) was developed and validated analytically and biologically using feces of Toraya Buffalo for cortisol metabolite measurements. Analytical validation comprises the parallelism test, accuracy, precision, and assay sensitivity. Biological validation performed by comparing concentration cortisol metabolites in feces of Toraya buffalo before and after pa’silaga tedong, a fighting contest of buffalo during the death ceremony of rambu solo at Tana Toraja, South Sulawesi Province. Results showed that the curve of serial dilution of fecal samples was parallel with the 11β-hydroxy-CM standard curves. The accuracy and sensitivity of the 11β-hydroxy-CM assay were 96.21%±7.59 and 0.78pg/well, respectively. The precision based on coefficient variation (CV) of intraand inter-assay was < 10% and < 15%, respectively. Biological validation results showed that cortisol metabolites concentrations after pa’silaga tedong were increased 3-10 fold than before pa’silaga tedong. In conclusion, the 11β-hydroxy-CM assay is a reliable assay for measuring cortisol metabolites in feces of Toraya buffalo.

The aim of this research was to determine the effect of giving neem leaf extract combined with jaloh towards the total of leukocytes and differential leukocyte in broilers that was infected with Eimeria tenella. This research samples were 20 Cobb stain broilers 14 days old. Design the research was complete randomized design with five treatments and each treatment consists of four repetitions. First treatment (P1) as negative control which was only given mineral water; second treatment (P2) as positive control was is given 5 mg/L anti-stress commercial in drinking water; Third treatment (P3) was given 1000 mg/L Jaloh extract; Fourth treatment (P4)was given 250mg/L neem extract; and fifth treatment (P5)was given 1000mg/L jaloh extract combined with 250mg/L neem extract. Anti-stress commercial and extract treatment dissolved in drinking water. The treatment start from 08.00 until 18.00 for ten days. Next in the 11th day (chicken 25 days old)was inoculated Eimeria tanella sporulatif as much as 1 x 104 ookista/ml orally. Then the blood was taken sampling when the chicken 30 days old (five days after infected). Blood sampling was done in the brachial vein. Furthermore, the number of leukocytes and differential leukocyte.Was calculated data were analyzed using complete randomized design with the help of SPSS for Windows 1.8 program. The result of this research showed that giving jaloh and neem leaf extract were not giving significant effect (P0,05) towards the number of leukocyte as well as differential leukocyte of broilers that was infected with Eimeria tenella. The conclusion of this research were giving jaloh leaf extract and neem for 10 days was not giving significant effect towards number of leukocytes and differential leukocyte broilers that infected with Eimeria tenella
