Abstract

Brucellosis in cattle is a disease caused by Brucella abortus due to the reduction in livestock population caused by abortion, stillbirth, weak birth, infertility and sterility. Brucella abortus has several potentialvirulence factors, i.e. virB11 gene that encodes VirB11 protein is an important virulence factor acts as an ATPase for assembling organelles when the bacteria replicate, helping to complete the bacterial cycle and agress to another cells. The aim of this study are to re-identification Brucella abortus and detect virB11 gene as encoding of B. abortus VirB11 protein in local isolates from Pinrang, NTT, strain vaccines S19 and RB51. The isolates Brucella abortus were re-cultured in Brucella agar base and re-identification is followed by microscopic with Gram staining and biochemical tested with urease, citrat, indol and TSIA test. virB11gene was detected with PCR method. The PCR result showed virB11 gene have DNA band 720 bp.virB11 gene are present in local isolates from Pinrang, NTT, strain vaccines S19 and RB51.

Abstract

Newcastle Disease or tetelo is one of main problem in poultry Industry in Indonesia. Prevention such as biosecurity control and routin vaccination program have been conducted to overcome this problem, but they have not given any great impact. Phyllanthus Niruri L. or meniran is well known as immunostimulatory. This research was aimed to reveal effect of Phyllanthus Niruri L. extract on chicken vaccinated with live vaccine LaSota. Administration of Phyllanthus Niruri L. extract was conducted on three different time which were 7 days before vaccination, 1 days after vaccination, and 3 days before and after vaccination. The amount of Phyllanthus Niruri L. extract administered were 2 ml, 2.5 ml, and 3 ml orally. Data of antibody titre were collected for 4 weeks after the treatment. It was obtained by measuring the antibody through Haemagglutination Inhibition test each week. According to the result Phyllanthus Niruri L. extract could increase the amount of antibody titre against Newcastle Disease. The amount of Phyllanthus Niruri L. extract given that capable to induced maximum of antibody titre was administered 1 days after the vaccination with amount 2.5 ml. It is suggested that Phyllanthus Niruri L. extract should be administered post vaccination to boost antibody synthesis.

Abstract

Staphylococcus aureus is one of the normal flora that can cause infection in injured skin. Resistance to antibiotics has an impact on the difficulty of therapeutic treatment so that other alternatives are needed. The purpose of this study was to observe the effectiveness of apple vinegar as an antimicrobial against Multidrug Resistant Staphylococcus aureus isolated from infection wounds in dogs in Surabaya. The methods in this study were the isolation of bacteria from 30 samples of dog festering wounds on Manitol Salt Agar (MSA) media and identification through macroscopic, microscopic, catalase tests, coagulase tests, hemolysis tests on Blood Agar media, and Voges–Proskauer (VP) tests. Bacteria that have included the S. aureus criteria were followed by sensitivity tests to the antibiotics Amoxycillin, Ampicillin, Gentamicin, Chloramphenichol, and Ciprofloxacin. Apple vinegar activity test was carried out using disk diffusion method against Multidrug Resistant Staphylococcus aureus. The results showed that of the seven S. aureus isolates, there were two isolates belonging to the Multidrug Resistant S. aureus. The results of the apple vinegar activity test showed the presence of antimicrobial activity shown by the formation of a clear zone around the paper disk with an average diameter of 24.06 mm at a concentration of 90%. The conclusion shows that apple vinegar has antimicrobial activity against Multidrug Resistant S. aureus which is isolated from dog festering wounds in Surabaya.

Abstract

Avian influenza virus (AIV) subtype H9N2 is one of the infectious agents that threatens laying poultry farms, because it has an impact on drastically reducing production in the population. The aim of this study was to isolate and analyze phylogenetically the partial gene encoding the surface proteins of the AIV subtype H9N2 from laying hens in East Java. A total of 30 suspected AIV subtypes of H9N2 were taken from laying hens which had decreased production by up to 70% in three sub districts each in Kediri, Blitar and Tulung Agung regency, in East Java Province. The virus was isolated in embryonated chicken eggs and then followed by a Hemagglutination (HA) test. Detection of the presence of H9 and N2 genes was carried out through Reverse Transcriptase polymerase Chain Reaction (RT-PCR) and continued with partial gene sequencing of the two surface proteins. Data analysis was processed using BioEdit version 7.2.5 and Mega 7.0. The results show that only one sample, namely code B2.2 from Blitar regency, is an AIV subtype of H9N2. The virus in this study belong to clade h9.4.2.5 of the AIV subtype H9N2. The conclusion of this study is that the VAI subtype H9N2 was successfully isolated from laying hens in East Java and successfully identified phylogenetically.

Abstract

The aim of this study is to identify the type of ticks infestation pattern on water monitor lizard (Varanus salvator, Byers, D. 2000) with regard parameters water monitor lizard species, stadium and region of the water monitor lizard’s body. The total samples of 250 ticks from 30 water monitor lizard (18 male lizards and 12 female lizards) were collected every day starting from noon to evening during July to August 2019 at the monitor slaughtering place in Buduran District, Sidoarjo Regency. The tick samples were identified by the permanent mounting slide method without staining and put in bottles containing 10% KOH for 1-10 hours, then each stadium used a nikon eclipse E100 microscope with a 40x magnification binocular microscope. Data was analyzed using Multiple Correspondance Analytics. The result indicate that 30 V. salvator (100%) are positive infested by tick and the samples obtained consisted of 133 Aponomma sp. and 117 Amblyomma sp. in all regions of the body.
