Screening of nematophagous-fungi from fresh faeces of grazing animals and soils.

The research article focuses on a study aimed at isolating nematophagous fungi present in the fecal samples of various grazing animals and soils in Malaysia.

Overview of the Research

• The research was conducted with the objective of screening and isolating nematophagous fungi from the feces of different grazing animals and soils in Malaysia.
• A total of 111 feces and 50 soil samples were collected for the study.
• Cultures were grown from these samples on 2% water agar plates with the growth of nematophagous fungi encouraged using a sprinkling-baiting technique.

Culturing Process and Isolation of Fungi

• The conidia, or spores, of the suspected nematophagous fungi were then inoculated, meaning they were deliberately introduced, onto 2% water agar plates.
• All isolates, the selected and cultivated microorganisms, were maintained on 2% cornmeal agar plates.
• Through this process, various species of pathogens, including Verticillium, Fusarium, and Arthrobotrys, were identified from the respective fecal and soil samples.

Results of the Research

• From the collected samples, 62.5% of the fecal samples and 100% of the soil samples were positive for nematophagous fungi.
• This result underscores the prevalence of a significant nematophagous fungi population in the faecal and soil samples.

Implication and Future Direction

• Despite the results, the study emphasizes that a lot of research still needs to be done to better understand these fungi.
• Aspects that require further study include the different fungi’s mode of action as well as their predatory behavior against parasitic nematodes—roundworms that can be harmful to both people and animals.
