pathogens (a thing that causes disease • the spread of pathogens by insects. OALD. ▪ As society, technology, and the environment change, pathogens evolve or spread, and the spectrum of infectious diseases expands. ▪ Gastric acid is the primary barrier against orally ingested enteric pathogens, and a major regulator of small bowel flora. ▪ Not every pathogen will respond instantly to events. ▪ Once the fish is affected, other pathogens, bacteria as well as protozoal parasites and fungi, will compound the overall situation. ▪ The chief aim is to reduce the solid volume of waste, offensive odours and to effect pathogen removal. ▪ The selective pressure is on all pathogens to mimic the passwords of their hosts. ▪ These specimens may provide sentinel indicators of new pathogens and emerging diseases. ▪ Viral control agents Insects are susceptible to a wide range of viral and bacterial pathogens.
