Pathogen | Waste and wastewater type present | Disease/symptoms | Notes |
---|---|---|---|
Bacteria | |||
Campylobacter spp. | Poultry, cattle | Gastro-enteritis, fever, headache, nausea, and vomiting | Sensitive to heat and anaerobic digestion. Not regarded as high risk. Has a low infective dose (100–800 cells can cause disease). It does not survive at a pH within the range of 1–4 or at temperatures >47 °C |
Clostridium sp. | Poultry, swine, cattle | Tetanus, botulism, blackleg (clostridial myositis)/respiratory and muscular paralysis, muscle spasms | Spores remain viable in the soil for years and are claimed to be a source of infection. Very resistant. |
Escherichia coli | Cattle, swine poultry (less) | Bloody diarrhea, vomiting, hemorrhagic colitis, haemolytic uremic syndrome | Facultative anaerobic. A strain of major concern is E. coli O157:H7. Grows on adverse conditions and can survive at low pH and temperatures. Can survive for long periods in soil and water. E. coli does not grow pH <3.6 or in high saline conditions. Infective dose about 10 cells. |
Listeria monocytogenes | Cattle, poultry | Listeriosis/meningitis, meningoencephalitis, brain abscess, cerebritis | Facultative anaerobic. Grows under adverse conditions and is resistant to heat and freezing. |
Salmonella sp. | Poultry, swine, cattle | Salmonellosis/food borne enteritis, diarrhea, fever, vomiting | Facultative anaerobic. Grows at pH of 4–8, and between 8 and 45 °C. Can survive for long periods in soil and water. |
Yersinia enterocolitica | Swine | Yersiniosis/Acute enteritis, lymphadenitis, nosodum ethema, septicemia, poliartitis and maybe death | Non-sporulated, non-capsulated; infrequent. Grows at pH 4–10 and at 4–43 °C. |
Viruses | |||
Porcine circovirus | Swine | Porcine dermatitis and nephropathy syndrome, porcine respiratory disease complex, postweaning multisystemic wasting syndrome | It is heat (70 °C) and chemical resistant. Can survive for long periods. Anaerobic digestion reduces infectivity. |
Coronavirus | Many animals | Sensitive to stresses. Does not survive for long periods. | |
Rotavirus | Many animals | Acute viral gastroenteritis/diarrhea | Potential zoonotic. Resistant to detergent and many antiseptics. Anaerobic digestion and UV reduces infectivity. |
Hepatitis E virus | Swine, sheep, poultry | Liver disease/anorexia, nausea and vomiting, hepatomegaly | Zoonotic. Persistence characteristics are not known. |
Influenza | Many animals | Flu | Zoonotic. Sensitive to heat, irradiation, detergents and oxidizing agents. |
Parasites | |||
Ascaris suum | Many animals | Ascariasis | Parasitic nematode, zoonotic; eggs survive under anaerobic stabilization (>80% viability after 20 days). |
Giardia sp. | Many animals | Giardiasis/diarrhea, cramps, flatulence. | Flagellate protozoan parasite, zoonotic. Very low infection dose. Cysts survive for long periods. In water oocysts survive <14 days at 25 °C. |
Cryptosporidium parvum | Many animals | Cryptosporidiosis/diarrhea, dehydration, nausea, vomiting | Very low infection dose (132 oocysts) Oocysts are resistant to disinfectants Relative sensitive to heat. |
Prions | Nervous system disease such as Creutzfeldt–Jakob disease | Resistant to high temperature, in general difficult to be disinfected. |
