Abstract

A polymerase chain reaction was developed to detect the proviral DNA of bovine leukimia virus in bovine lymphocytes. Milk and blood samples from infected and uninfected cows were tested. None of the bovine leukosis free animals gave a positive response and 58% of the infected cows showed positive signals. When the DNAs 25ul of blood. 25.000 lymphocytes or 1.000 lymphocytes were amplified. positive results were recorded more frequently in cows with persistent  lymphocytes than in cows with normal  lymphocyte counts.

Abstract

Clinical signs indicated that Swollen Head Syndrome (SHS) was suspected to be present in Indonesia. Serological investigation was carried out by collecting a number of 242 serum samples from Tangerang, Bogor, Cianjurm Ciawi, Cicurug dan Magelang, tested using serum neutralization (SN) test. The results of SN test indicated that SHS has been identified in these investigation areas. Based on the fact that these are the center for parent stock breeders it could be suspected taht the disease might have been speread to several areas of chicken farms in this country.It would be wise if a control program be formulated since this time, to ensure that everything is well prepared in case SHS situation develops into unfavorable condition.

Abstract

Avian Influenza virus (AIV) still plays as a major cause of the death in poultry in Indonesia and around the world. The aim of this research was to determine the pathogenicity and to analyze the phylogenetic and genetic distances of hemagglutinin gene of isolated AI viruses in Indonesia in 2012-2013 particularly from West Java, Central Java, and North Sumatra. Samples were obtained from poultry farms that suffered from AI outbreaks, were inoculated and propagated in ten days old specific pathogen free (SPF) embryonated chicken eggs. Harvested allantoic fluids at 5 days after inoculation were tested for hemagglutination activity. Positive allantoic fluids were further tested to determine the hemagglutinin and neuraminidase subtype using real-time reverse transcription polymerase chain reaction (RRT-PCR) and to be prepared for sequencing using reverse transcription polymerase chain reaction (RT-PCR). The sequence of hemagglutinin genes were analyzed for the amino acid pattern of the cleavage site region and the genetic distances and relationships of those viruses. The result indicated that all of the isolates are classified as HPAI with the pattern of cleavage site regions are QRESRRKKR and QRERRRKR. Six isolates are classified as H5N1 and 3 isolates are H5Nx. All of the isolates have close genetic relationship with the genetic distances less than 0.3 between one to another and also with several AI viruses that caused previous outbreaks in Indonesia.

Abstract

Rabies control programs, including extensive vaccination with attenuated or inactivated vaccines. However, such vaccines are not without problems and can have detrimental effects. Indeed attenuated vaccines can revert to a more virulent form, and inactivated vaccines may produce serious side effects. These facts, have led to the creation of a new generation of vaccines: recombinant-DNA vaccines, synthetic peptide vaccines, and anti-idiotypic vaccines. The aim of this study is to study the result of anti-idiotypic immunization methods in dogs detected by using enzyme linked immunosorbent assay (ELISA). Anti-idiotype antibodies against rabies (Ab2) were isolated from chicken blood, separated by means of ammonium sulfate precipitation, then dialyzed using PBS pH 8.0 for 24 hours at 2 – 8 oC and purified using affinity chromatography column. Three groups of dogs were immunized, group I was immunized intramuscularly (i.m) with purified IgY, group II was immunizded oraly (p.o) with purified IgY and group III was immunized intramuscularly (i.m) with rabies viral vaccines.  The antibody response (Ab3) was detected using Agar Gel Precipitation Test (AGPT). The efficacy of Ab3 was detected using ELISA. By ELISA, the result of immunization indicated that the level of Ab3 titers of anti-idiotypic vaccine immunized dogs intramuscularly are more than 0.5 IU/ml (protective according to WHO standard), and significantly higher than oraly immunization, but it significantly lower than Ab3 titers of rabies viral vaccine immunized dogs. The conclusion of this study is intramuscularly immunization of anti-idiotypic antibodies can induce protective immune response against rabies virus, although its lower than antibodies titer of viral vaccine, it has a good prospect for vaccine development in controlling rabies

Abstract

Identification of pathotype of Avian Influenza Virus (AIV) subtype H5N1 isolates is very important. Thisresearch aimed to identify the pathotype of AIV subtype H5N1 isolated from household waterfowls in West Javabased on molecular markers of amino acid sequences of the Hemagglutinin (HA) cleavage site. Fragments of HAgenes of 21 isolates were amplified using RT-PCR with a primer pair that flanking the cleavage site region, andsequenced with dideoxy-termination method with ABI automatic sequencer (Applied Biosystems). Multiple alignmentof nucleotide and their deduced amino acid sequence were analyzed using ClustalW from MEGA 3.1 program.The result shows that all H5N1 isolates (21 isolates) possess polybasic cleavage sites with 2 patterns ofamino acid sequence, i.e QRERRRKKR (20 isolates) and QRESRRKKR (1 isolate). This finding indicates that all ofthe viruses isolated in this research were of highly pathogenic avian influenza (HPAI) strains.Keywords: cleavage site, waterfowls, HPAI

Abstract

Avian Influenza (AI) is a zoonotic viral disease in birds which demands priority on control and measures. Spread of AI virus can occur directly or indirectly. The use of disinfectant and handling of hatching egg waste into one of the actions that must be applied in hatchery to control the spread of AI virus.  This research aim to compared two types of desinfectant in eliminating AI virus. The research was designed into 6 groups. Group I was SAN (Specific Antibody Negative) eggs as untreated negative control, group II was SAN egg treated by fumigation using potassium permanganate (KMnO4) and formalin in room temperature for 20 minutes, group III was SAN eggs soaked in benzalkolnium chloride (BKC) in room temperature for 30 seconds, group IV was SAN contaminated by AI H5N1 virus and fumigated by potassium permanganate and formalin in room temperature for 20 minutes, group V was SAN eggs contaminated by AI H5N1 virus and then soaked in benzalkonium chloride in room temperature for 30 second, and group VI was SAN eggs contaminated by AI H5N1 virus in room temperature for 10 minutes as positive control. AI H5N1 virus detection was done by using RT-PCR (Reverse Transcription Polymerase Chain Reaction) and confirmed by isolation in Embyronated Chicken Egg. The result of this research showed that the use of potassium permanganate  and formalin disinfectant gave little better performance compared to benzalkoniun chloride in eliminating AI H5N1 virus on hatching eggs.

Abstract

The aim of the present study was to determine the survival of L3 populations in intestine ofchickens exposed to experimental Ascaridia galli infection. Nature female adult worm were obtained fromlumen of village chickens in a comercial abattoir in Bogor. The eggs (L1) obtained from uteri female adultworms were incubated in sterile aquadestilata at room temperature for 10-20 days developed embrionatedeggs (L2). Five groups (A-D) of 80 head chickens were infected with, 6000 L2 A. galli respectively. Thechickens of group A were infected six times with dose of each 1,000 L2 with an interval of one hour. Thechickens of group B were infected three times with dose of each 2,000 L2 with an interval of two hours.The chickens of group C were infected six times with dose of each 3,000 L2 with an interval of three hours. The chickens of group D were infected one time with single dose 6,000 L2. A. galli L3 were recovered from intestines of 80 heads chickens seven days after oesophagus inoculation with 6,000 L2.The result showed that total 702,000 L1 and 628,000 L2 collected from 124 A. galli female adult worms.The percentage of L1 developed L2 is 89.46% and L2 developed L3 is 11.27%. Significant survival of L3higher populations in intestine of chickens observed only in the group D. The results indicated thatchickens infected high dose of A. galli caused the decrease of host defence against ascaridiosis. Keywords: Ascaridia galli, embrionated eggs, larvae
