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.

Control of Gastrointestinal Nematodes Infection in Small Ruminants by Nematophagous Fungi Riza Zainuddin Ahmad; Beriajaya .; S Hastiono

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

The contamination of fungi is an important problem which must be known and controled. Mycelia sterile is one of contaminated fungi which is seldom known and must be studied. Different morphology, reproduction and physiology of this fungi is important to study because of the strategy for its control. The aim of this research is to study mycelium sterile and the procedure for its controll. The observation was conducted on fungi suspected included mycelia sterile for 3 years at IRCVS Mycology laboratory. Isolation, identification and re inoculation in agar medium wasconducted on suspected fungi as mycelia sterile. The results show that 10 fungi are mycelia sterile. From this research result, it can concluded that mycelium sterile is a contaminating fungi and it is assumed that it can be controlled.Keywords: Mycelia sterile, contamination, control.

5. Important Mycotic Diseases In Animal Livestock Caused By Some Agriculture Fungi In Indonesia Riza Zainuddin Ahmad; Djaenudin Gholib
The International Journal of Tropical Veterinary and Biomedical Research Vol 1, No 1 (2016): Vol. 1 (1) May 2016
Publisher : The Faculty of Veterinary Medicine of Syiah Kuala University

One of contribution for Indonesian state from Agriculture sector is livestock animals. This livestock animals in Indonesia is divided to large and small ruminant, poultry, and other commercial animals. All these animals can be infected by some agriculture fungi which causes mycosis. The disease cause economic loss by morbidity and mortality. In chicken (poultry), aspergillosis caused by Aspergillus sp can be very important among mycotic diseases. In ruminant ringworm (dermatofitosis) caused by dermatofit fungi which infected skin, and mastitis caused by fungi in Dairy cattle causes decrease milk production. Histoplasmosis caused by fungi such as Histoplasma farciminosum is called Selakarang, infect horse. This paper discribes these mycotic diseases and control and to give more information of fungal disease caused by some agriculture fungi.
