Penyakit mikotik pada unggas di Indonesia masih diabaikan dan dianggap kurang penting dibandingkan dengan penyakit unggas oleh penyebab lain. Hal ini disebabkan oleh bermacam-macam faktor, antara lain karena pertimbangan ekonomi, baik dari segi diagnosis yang masih kurang efisien, pengobatan yang masih belum efektif maupun prioritas yang dewasa ini masih menduduki posisi ke-4 setelah penyakit viral, bakterial dan parasitik. Namun demikian, beberapa mlkosis seperti aspergillosis dan kandidiasis, serta kontaminasi pakan oleh kapang toksigenik, yang pada gilirannya akan menimbulkan mikotoksikosis atau aflatoksikosis pada ternak yang mengkonsumsinya, merupakan beberapa contoh penyakit mikotik penting yang tidak dapat diabaikan begitu saja, mengingat iklim di Indonesia yang tropis basah merupakan wilayah yang subur bagi pertumbuhan cendawan. Hal ini terbukti dari hasil pemeriksaan beberapa sampel yang diperoleh dari berbagai lokasi di Indonesia, dengan sering dapat diisolasinya beberapa cendawan patogenik seperti Aspergillus spp. dan Candida sp. dari sampel organ tubuh, serta kapang toksigenik seperti Aspergillus spp., Penicillium spp. dan Fusarium spp. dari sampel pakan unggas dan komponennya.

WARTAZOA, Indonesian Bulletin of Animal and Veterinary Sciences Vol 12, No 3 (2002)
Publisher : Indonesian Center for Animal Research and Development

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. Key words: Biological control, nematophagous fungi, small ruminants

The Utilization of Fungi and Their Products to Increase Livestock Production Riza Zainuddin Ahmad
WARTAZOA, Indonesian Bulletin of Animal and Veterinary Sciences Vol 21, No 2 (2011): JUNE 2011
Publisher : Indonesian Center for Animal Research and Development

Fungi as part of eukaryotic organisms play an important role for livestock. Some fungi are detrimental because they cause animal diseases, and some fungi are beneficial because they can improve animal productivity. The use of fungi that benefit from starting he has done as agents of biological control and to be as probiotics.Within the fungi, the use of simple technologies to high level degree for the benefit of cattle is developed. This paper describes some fungi that are beneficial and direction and suggestion to develop research on veterinary micology in Indonesia. Key words: Fungi, mycology, use, animal livestock

Paecilomyces lilacinus and Verticillium chlamydosporium Fungi as Biological Control of Fasciolosis Riza Zainuddin Ahmad
WARTAZOA, Indonesian Bulletin of Animal and Veterinary Sciences Vol 23, No 3 (2013): SEPTEMBER 2013
Publisher : Indonesian Center for Animal Research and Development

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. Key words: Natural control, F. gigantica, P. lilacinus, V. chlamydosporium

The Fungimetarhizium Anisopliae as a Biocontrol for Ectoparasite Mites and Ticks in Livestock Riza Zainuddin Ahmad
WARTAZOA, Indonesian Bulletin of Animal and Veterinary Sciences Vol 14, No 2 (2004): JUNE 2004
Publisher : Indonesian Center for Animal Research and Development

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

The Advantage of Yeast Saccharomyces Cerevisiae for Livestock Riza Zainuddin Ahmad
WARTAZOA, Indonesian Bulletin of Animal and Veterinary Sciences Vol 15, No 1 (2005): MARCH 2005
Publisher : Indonesian Center for Animal Research and Development

Saccharo nyces cerevisiae is a yeast that is useful for human and animal . It can be used for producing food and for biotechnology of industrial purposes . Recently. it is used as probiotic and immunostimulant to improve livestock productivity and health . Research results indicate that the utilization of S . cerevisiae as feed additive in animal feed has a positive correlation to the body weight gain of the animal . This paper describes the importance of S. cerevisiae in improving livestock productivity and health. Key words : S. cerevisiae, probiotic, immunostimulant, livestock

Duddingtonia flagrans is selected nematophagous fungi as biological control to nematode worm. Theaim of this research was to show that the survival of in vitro tested to D. flagrans mold growth is effectedby artificial saliva, rumen fluid, enzymes and agar-cement and comin block applicator. The testing wasdone two steps : Firstly the conidia’s was multicated and the secondly the growth of D.flagrans tested insaliva, rumen fluid and comin block, agar cement applicator. The result showed that mold could surviveand grow in condition such as in gastrointestinal fluid of sheep and in comin block and in agar-cementapplicator (1 and 2%). It can be concluded that D. flagrans could grow in medium containing rumen fluid,saliva, enzymes and comin block and agar-cement applicator.

The use of Duddingtonia flagrans as the biological control of nomatode infections has been widelyreported. However, no report is available on the use of yeast Saccharomyces cerviciacae for such purpose.The aim of this study was to ivestigate the use of both fungi to reduce the number of Heamoncus contortusinfective larvae. Agar and fecal media containing the spore of the fungi was inoculated with infected H.contortus larvae (3rd stage). Fecal media containing the fungi was prepared by oral inoculation of sheepwith liquid containing 106, 107 spores of D. flagrans, and 106, 107 spores of D. flagrans, and 106, 1012 sporesof S. cerviciae. The number of larvae trapped in the fungi was counted. The result showed both fungi wereable to reduce the number of infective lave. However, for D. flagrans, beside it able to kill the larvae, it alsoable to trap the larva which did not occur in S. cerviceae. The combination of both fungi can be used to reduceof the number of invected H. contortus larvae.

A study was carried out to determine the ability of nematophagous moulds (Arthrobotrys oligosporaand Duddingtonia flagrans) to trap and reduce the number of H. contortus larvae III. Tests was conducted inpetri dishes containing agar medium, the moulds and Haemonchus contortus larvae. The ability of bothmould in trapping H. contortus larvae III was observed 3; 4; 10; 24 and 48 hours post-incubation, whereas theability of both mould in killing the larvae was observed 0,5; 3; 6; 9; 12; 15; 21; 24; 27 and 48 hours postincubation.The results showed that A. oligospora was more capable in trapping and reducing H. contortuslarvae III than Duddingtonia flagrans (p<0, 01). It was also evident that A. oligospora of Denmark originwas more capable in trapping and killing Haemonchus larve than that of local isolate. It is clear from thisstudy that A. oligospora is potential biological method for controling H. contortus infection in animals.
