The availability of specific and rapid detection methods is essential for monitoring the health status of farmed species, particularly in viral disease as in this case early diagnosis is a critical factor in containing disease outbreaks. Jembrana Disease Virus (JDV) is a lentivirus that causes an acute, severe disease syndrome in infected Bali cattle in Indonesia, resulting in heavy economic losses because of the high mortalities. The virus-host interaction and the modes of transmission are still unknown. The goal of the research was to designa probe candidate of Jembrana Disease Virus based on envelope-transmembrane (env-tm) gene to optimize Jembrana disease detection method. The DNA fragment derived from env-tm of JDV was used, cloned in pGEX-TM and expressed in E.coli DH 5α. Sequence analysis was conducted with BLAST programs from NCBI. Sequence analyses of the fragments of env-tm clone, indicated that it has a very closed genetic relation with 97,68% homology identity. Probe was designed based on the conserved region of env-tm using Geneious resulted in JT2 252 bp long. BLAST analyses showed that probes had high specifity to other strains of JDV in Indonesia.Key words : probe, env-tm, JDV, specifity, sensitivity.

Toxoplasma gondii is one of the opportunistic pathogen that causes toxoplasmosis. Infection of Toxoplasma gondii has been estimated as high both in human and animal. The manifestation of infection were abortion, hydrocephalus, brain calcification, chorioretinal scar, and loss of productivity even to death in patients with acquired immunosuppression. Early diagnostic method which are rapid and accurate is essential for T. gondii detection because of its high prevalence. The purpose of this study was to develop a sensitive probes derived from Surface Antigen 1 (SAG1) for detection T. gondii and to examine the specificity and sensitivity of probe as diagnostic tool for toxoplasmosis. This research used SAG1 gene of T. gondii local isolate IS-1 that was cloned into pGEX-2T and transformed into Eschericia coli DH5α. The sequence of SAG1 was labeled with DIGoxigenin (non radioactive labeled) using PCR DIG Labeling Mix to derive 213 bp (probe-TS). BLAST and dot-blot hybridization analyses showed that probes had high specifity with other strains of T. gondii. Probe was able to detect T. gondii DNAup to 10 ng/μl of total sample DNA.

The increasing beef cattle population in Indonesia is not significantly with high demand of meat every year. The insignificant increasing in population is caused by fertility decreasing, infectious disease and the reduction amount of forage land. The factor which causes cattle fertility decreasing can’t be separated from the ovarian and follicular diameter which have an effect on high various reproductive appearance. Parameters that used for knowing reproductive appearance of cattle are Service per Conception (S/C) and Calving Interval (CI). The aims of this study was to describe ovary sizes and follicular diameter in cattle, to describe ovary and follicular diameter toward S/C and CI variation. This research uses female cattle, 8 Simmental-PO (SimPO) and 9 Peranakan Ongole breeds (PO), multiparous, are not pregnant, 4-8 years old, Body Condition Score (BCS) 2.5-3.5, peak phase estrus, has no reproductive problems, clear recordings and live in the area of farmer in Jatinom District, Klaten Regency, Central Java Province. Cattle are examined for ovarian size and follicle size using ultrasonography. S/C and CI data were obtained from records of artificial insemination cards (AI). The data obtained were analyzed by t test. The results of this study showed there were no differences in the diameter of ovaries in the size of SimPO and PO cattle (P> 0.05), there were no differences in the diameter of SimPO and PO cattle follicles (> 0.05), there were differences in ovarian and follicular diameter sizes with respect to S/C and CI in cattle with good and bad reproductive performance (P <0.05). The conclusion of the study showed that there was no difference in ovarian and follicular diameter size in SimPO and PO cattle (P> 0.05) but there was an influence on S/C and CI (P <0.05).
