The disease caused by gastrointestinal nematodes infection in small ruminants in Indonesia is quite unprofitable. Control with anthelmintic developed a negative effect of anthelmintic resistance and residue in tissue if anthelmintic are given routinely. Biological control is one of the control methods using microorganisms especially molds. The moulds can form traps and destroy the body of larvae and eggs by hife and produce toxins. Few isolates of nematophagous fungi such as Arthrobotrys spp. and Monacrosporium spp. were found from surveys done in West Java. Applications of these fungi as biological control against nematodiasis is promising as indicated from in vitro and in vivo studies. Â Key words: Biological control, nematophagous fungi, small ruminants

Indonesian Bulletin of Animal and Veterinary Sciences Vol 14, No 2 (2004)
Publisher : Indonesian Animal Sciences Society

Metarhizium anisopliae has been known as a biological agent that can kill and control pests especially arthropods. Recently the efforts on controlling arachnid: mites and scabies known as ectoparasites for ruminants have been done by using this fungus. This fungus can be used as a biological control on ectoparasite since it is not harmful for human and animal health. At the same time the availability of microbes as the Indonesian germ plasm especially fungi is sufficient to support the development ofM. anisopliae as a biological control agent, and eventually its development prospect as a controlling for ticks and mites in the future is promising. Key words: Metarhizium anisopliae, control biology, ectoparasite

Publisher : Indonesian Animal Sciences Society

Selakarang is a fungal disease attacking horses. Although the mortality rate is low, the morbidity is high leading to economic loss. The island of Sulawesi has about 151.000 horses and they are distributed in 5 provinces: North, Central, West, South, and South-East Sulawesi which potentially has endemic outbreaks caused by the Selakarang fungus, Histoplasma farciminosum. The disease might be endemic throughout Indonesia if the horse trading is not monitored. In Maros, South Sulawesi, the disease is found with symptoms in the form of nasal, cutan, and ocular symptoms. Ignorance of the appropriate authorities will increase the likelihood of spread of the disease. According to the Staatblad act produced in 1912 and the disease belonged to the zoonotic disease and when it is not well handled and properly managed, infection to human may occur. Prevention is better than treatment. In the future, we may propose to produce inactive vaccines and develop serological test to detect antigen and antibody in RIVS collaborating with other government agencies or private parties interested in this disease control. Key words: Horse, Selakarang Disease, Sulawesi

Publisher : Indonesian Animal Sciences Society

Fasciolosis is a worm disease caused of Fasciola gigantica and an important problem in husbandry especially for cattle. Controlling of this worm disease can be conducted by prevention and treatment. The use of antihelminthic is commonly causes a resistance problem. Natural control by mold such as Paecilomyces lilacinus and Verticillium chlamydosporium can be applied to reduce egg of F. gigantica. Although it was recently found, in vitro study gave satisfied result. This gives a new hope in controlling the disease although the extend application still needs to be studied. This paper discussed about the use of P. lilacinus and V. chlamydosporium for reducing F. gigantica population. Â Key words: Natural control, F. gigantica, P. lilacinus, V. chlamydosporium

The study on cases of abortion in cow caused by fungi have never been reported so far in Indonesia. The aim of this research is to get prevalence of cows have not and have aborted, both have reproductive disorder, and health cattles associated with percentage of fungi isolated.The study included both field survey and laboratory examination of samples. The samples of vaginal fluid were collected by using cotton swabs in cow which had suffered abortion or cow had repeated breeding, as well as freeze dried semen for artificial insemination (AI), and also examining the occurrence of abortion in cattle. The samples were collected in Sukabumi and Bandung, and then cultured in Sabouraud Dextrose Agar by stretch method, followed by incubation at 37oC. Number of samples collected consisted of 56 samples of cattle which had suffered from abortion and cow that had reproductive problems; 38 samples as control; five samples of freeze dried semen. There were no cases of abortion observed when field survey was conducted, therefore organ samples were not available for pathological and histophathological examination. Further examination on growth rate of yeast showed 20% of yeast presented in cows with abortion, 17% in cows with reproductive problem and 14% in normal cattle. On the other hand,there were samples that did not show any growth of yeast recorded f rom cows with abortion (15%)cattle with reproductive problem (7%) and normal cows (27%). Meanwhile, only twowith 2 yeast growth observed in semen samples. It was concluded that samples from cattles with reproductive problems (with and without aborted experiences) showed higher number of growth of yeasts compared with normal cow (P<0,05). Freeze dried semen were having risk of contamination by yeasts. There was no different on growth rate of fungi between reproductive problem and with abortion cow (P>0,05).
