Abstrak: Etawah cross breed goat was domesticated to fulfill human need on meat and milk. As a dairy milk producer etawah cross breed goat is susceptible to subclinical mastitis. Subclinical mastitis is often caused by Streptococcus agalactiae. Several methods had been developed to prevent subclinical mastitis, i.e., promoting sanitation and higiene, teat dipping, and vaccination. The objective of this reseach was to identify the efectiveness of irradiated vaccine S. agalactiae to prevent subclinical mastitis caused by S. agalactiae through observation of leucocytes profile. This research used pregnant healthy goats with four until five months gestation that were vaccinated three times with interval of 2 weeks. The vaccine volume used was 2 mL and contain 108 cfu/mL S. agalactiae administerated by subcutaneous route. The blood samples of 9 pregnant Etawah cross breed goats (5 vaccinated goats and 4 control goats) were taken out every one week post vaccinated. Samples were prepared to be blood smear preparation and stained with Giemsa and examined on leucocytes profile (relative value and total value). This study showed that limphocytes from treated etawah cross breed goats were higher than control. Relative and total value of lymphocytes in prevactination were significantly different (P<0.05) (73.67±2.05% and 5230±87 cell/μL) also postvactination 3rd (66.00±4.08% and 5676±1520 cell/μL). The study concluded that the secondary immune response from vaccination program already formed to prevent subclinical mastitis in etawah cross breed goat caused by S. agalactiae.

Judul: Kandidat vaksin iradiasi Streptococcus agalactiae untuk pencegahan mastitis subklinis pada ruminansia
Abstrak: Subclinical mastitis (SCM) is a disease that often infects dairy cow, which then decline milk production. Streptococcus agalactiae is well known as a dominant causative agent of SCM. An experiment to obtain gamma irradiated candidates vaccine of S. agalactiae for the prevention of subclinical mastitis in ruminants have been conducted. S. agalactiae bacteria selected for the irradiated vaccine material was isolated from dairy cows of subclinically mastitis from dairy farm in Bogor and Garut area. The S. agalactiae used in this experiment was group B (GBS) type, which is uncapsulated and has haemaglutynine (Hn+) property. Based on dose irradiation orientation, 17 Gy dose was found to weaken the GBS bacteria to have 50% lethal dose (LD50), which therefore, utilized to manufacture live vaccine. Irradiated GBS surface protein was characterized by SDS-PAGE and resulted to find more than 75 kDa of the protein’s molecular weight, where minimun of antigenically substance is 10 kDa. Infecting of the irradiated GBS using mice resulted in lack pathogenic properties of the bacteria, which is histophatology drawn that the mammary gland alveolly of mice grouped vaccinated with irradiated GBS and vaccinated then challenge, were remain producing milk, and significantly not different as compare to control animal. GBS vaccine irradiation did not cause inflammation of the mammary glands of mice tested, evidences showed that number of udder interstitial inflammatory cells around alveolly and gland epithelial cells in vaccinated mice groups were not significantly different as compare to the control group. Most interstitial inflammatory cells in challenged groups are found in mice that were challenged with virulent GBS and significantly different to be found more as compare to vaccine and control groups. Enzyme Linked Immunosorbent Assay (ELISA) to Ig-G serum showed levels of higher immune response in mice vaccinated group compare to control group. The overall experiment confirmed that attenuated GBS using gamma ray irradiation capable to induce immune response. This evidences were confirmed by an observation result in the application of GBS irradiated vaccine at Etawah dairy-goat, where immune responses are induced in those dairy-goats, and also were showed by the evidences found of higher concentration of Ig-G serum by ELISA in the vaccinated group than the control group. Milk production of vaccinated goat had no effect by vaccination. In summarize, irradiated SGB vaccine does not affect milk yield.

Abstrak: Manusia (Homo sapiens) seperti halnya makhluk hidup yang lainnya membutuhkan tempat yang ideal untuk kelangsungan hidupnya. Dan untuk itu bukan saja materi yang dibutuhkan, akan tetapi kebutuhan rohani sudah selayaknya pula dipenuhi. Taman adalah suatu susunan massa di dalam suatu susunan ruang terbuka, untuk melengkapi lingkungan hidup agar diperoleh lingkungan hidup yang ideal. Pada kebanyakkan orang ada pendapat bahwa taman adalah suatu kebutuhan rohani yang terlalu mahal, lebih-lebih di kota-kota besar dimana sebagian penduduknya tidak mempunyai halaman rumah untuk dijadikan taman. Padahal tidaklah selalu demikian. Susunan dari pot bunga-bungaaan yang tersusun indah pada dinding rumah dapat merupakan sebuah taman yang sederhana yang membutuhkan ruang relatif sempit. Untuk taman-taman yang membutuhkan ruang relatif sempit atau taman-taman dalam sekala kecil, acapkali si pemakai sekaligus bertindak sebagai perancang dan pelaksana. Akan tetapi tidak begitu halnya pada taman-taman yang bersekala besar, baik itu berupa taman rumah tinggal yang berhalaman luas ataupun pada tingkat yang lebih besar lagi seperti Taman Mini Indonesia Indah dan Taman Nasional. Pada taman yang demikian itu jumlah manusia yang terlibat di dalam penyelenggaraannya lebih banyak. Bahkan mereka dapat berasal dari instansi-instansi yang berbeda yang bekerja sama sehingga terciptalah taman yang sesuai dengan keinginan si pemakai.
