Abstract

Influenza A viruses which belong to the Family of Orthomyxoviridae are a group of viruses withsegmented ssRNA genome. The viruses can be subgroupped into many subtypes on the basis of theirsurface glycoproteins, hemagglutinin (HA) and neuraminidase (NA) proteins. Among the HA subtypes, H5and H7 have been found to be the most pathogenic. Conventional diagnosis of the viruses is usuallyperformed by isolation of the viruses in embryonated eggs, and hemagglutination (HA) and hemagglutinationinhibition test. Although those methods are sensitive and accurate, they are time consuming and requirelaboratory facilities with high biosafety level. Commercial methods such as emzyme-linked immonosorbentassay (ELISA) and immunoflurescense assay also provide a rapid result but less sensitive and specificthan conventional methods. Molecular diagnosis by amplification of M and H5 genes using one strepsimplex reverse transcriptase-polymerase chain eraction (RT-PCR) provices a rapid and accurate diagnosisfor the viruses. A study was therefore conducted to evaluate the accurate and rapidity of such the moleculartests for diagnosis of avian influenza A virus, subtype H5. As many as 10 sample of the virus isolateswhich were available at the Animal Desease investigation Center in Wates, Yogyakarta, were uses in thisstudy. The virus isolates were firstly propagated in specific antigen negative (SAN) chicken embryos andtested by HA/HI test. The viruses were then subjected for the RT-PCR test with varying annealingtemperatures of 500C and 520C. The result showed that all 10 isolates were type A influenza virus and 8out of 10 were influenza A subtype H5 influenza virus. RT-PCR used in this study appears to be moresensitive, rapid and accurate as compared to those by serological and isolation of the virus in embryonatedeggs.

Abstract

Ovarian dynamics in the garut ewes had never been studied continuously by using ultrasonography.The aim of this study was to observe development of the follicles and corpus luteums in the estrous cyclein the garut ewes. Garut ewes (n=6) with body weight 30.00±4.05 kg which had normal estrous cycle wereused in this study. All ewes were synchronized by using CIDR-G implantation for 14 days. Ovulation of thedominant follicle, development of the follicle waves and corpus luteum were observed continuously everyday during the estrous cycle after CIDR-G removal. The number of small (2-3 mm in diameter), medium (4-5 mm in diameter) and large (>5 mm in diameter) follicles were aligned during the estrous cycle. Follicleand corpus luteum diameters were measured by using built in caliper in the ultrasound. The resultsshowed 1) the average length of estrous cycle was 19,2±0,8 days; 2) ovarian follicle growth occurred inthree waves during the estrous cycle; 3) the number of preovulatory follicles were 1-2 follicles; 4) theaverage maximum diameters of preovulatory follicle was 7.5±0.5 mm; 5) the average maximum diametersof corpus luteum was 7.3±0.4 mm. In conclusion, the estrous cycle in garut ewes was 18-20 days with 3follicular waves.

Abstract

This research aimed to isolate exopolysaccharides (EPS) producing Lactobacilli isolated fromsumbawa mare’s milk and its potential as prebiotics for modulating the growth of Bifidobacteriumbreve. Nine strains of Lactobacillus sp. were screened for their capabilities to produce EPS usingmodified MRS medium containing sucrose. Prebiotics potential of the EPS was verified by culturingB. breve JCM1273 in TOS medium containing EPS. The results showed that all strains ofLactobacillus sp. produced EPS on MRS sucrose medium and two strains (Lactobacillus SK3.1 andLactobacillus SK4) produced more EPS compared to the other strains tested. Bifidobacteriumbreve JCM1273 showed weak activity while in direct metabolism of EPS produced by Lactobacillussp. SK4 and its growth was enhanced on acid hydrolyzed EPS. Since this phenomenon mighthappened when the EPS exposed by the low pH during gastric passage, hence the EPS might be apotential source to be developed as prebiotics. Nevertheless, further investigation is necessary toevaluate the bifidogenic affects of EPS in Lactobacillus sp. SK4.

Abstract

A study to evaluate the serum macrominerals status in clinically healthy Ettawa crossbred goatshave been carried out in order to obtain the baseline data for monitoring health condition. A total of 60Ettawa crossbred goats were used in the study. The demographic characteristics of the animals groupwere: (i) young male and female goats (5-8 months); (ii) adult male and female goats (1.5 – 4 years); (iii)pregnant, and (iv) lactating animals. The serum macrominerals concentrations were within the referencestatus of other small ruminant species. The mean calcium (Ca), potassium (K), and chloride (Cl)concentrations were not significantly difference (P>0.05) between the animals groups. The Na concentrationof adult female goats was 139.33 ± 1.94mmol/L and was significantly lower compared to the animals inthe other groups (P<0.05). The inorganic phosphor (Pi) concentrations in pregnant and lactating animalswere significantly lower (P<0.05) compared to that in young, adult, male and female goats. The macromineralsconcentration in serum was influence by the physiological status of the animals.

Abstract

Avian Influenza (AI) is an infectious disease in poultry, caused by type A of avian influenza virus(AIV), in the family of Orthomyxoviridae. Almost all birds’ species are sensitive to the AI. Beside theability to infect various species of poultry. AIV type A has a wide range of host including all bird species,mammals, dan human. Today some scientists reported that the cases of AI in mammals, including humansare increasing. This condition suggests that the AI virus circulated in the field may have some mutationsin the amino acid determinants responsible receptor binding site (RBS). A research was therefore designedto investigate the molecular level of HA gen fragment responsible for receptor binding site of AIV isolatedfrom various poultry since 2003 to 2008. Molecular characterization was based on the amplification ofreceptor binding site of HA gene by reverse transcriptase polymerase chain reaction (RT-PCR). All RTPCRof HA gene positive products were sequenced to determine the nucleotide composition at the targetedfragment. Sequences yielded were analyzed by program Mega 4.0 versions, including multiple alignment,deductive amino acid prediction, and establishment of phylogenetic tree. The results show that all AIVisolates could be determined of some conserved amino acids residues responsible for RBS which indicatethe binding preference of avian like receptor, sialic acid ? 2, 3 galactose except isolate A/Layer/Jabar/MHW-RBS-02/2008 which could be found a deletion of amino acid at position of 129 dan mutation of 151isoleucine into threonine. Phylogenetic study showed that clustering of AIV did not base on species of birdor geographic origin of AI viruses which were studied.
