Water and food borne bacterial diseases Submitted by : nahima ANHUMMsc microbiology 2nd semesterSubmitted to Dr. Asma UNIVERSITY OF HARIPUR

Waterborne bacterial disease

•An illness due to infection with bacteria contaminating the water supply.

•Waterborne diseases are caused by pathogenic microorganisms that most commonly are transmitted in contaminated fresh water.

Causes and Symptoms of Waterborne bacterial diseases

• Waterborne disease is easily transmitted when contaminated water is used for any of the following purposes:

• drinking, making ice cubes, washing uncooked fruits and vegetables, making baby formula, brushing teeth and washing dentures or contact lenses.  

• Many waterborne pathogens can also be acquired by consuming contaminated food or beverages, from contact with animals or their environment, or through person-to-person spread.

Symptoms of Waterborne bacterial diseases

•Waterborne illnesses can cause a variety of symptoms. While diarrhea and vomiting are the most commonly reported symptoms of waterborne illness, other symptoms can include skin, ear, respiratory, or eye problems.

Water borne bacterial diseases •Dysentery•Cholera•Cryptosporidiosis (Cryptosporidium spp.)•Botulism•Typhoid Fever

Dysentery•Description severe, often bloody

diarrhea, vomitting, fever; life-threatening if untreated

•Responsible pathogen Shigella dysenteriae bacteria or Entamoeba histolytica amoeba

•Route of exposure gastro-intestinal•Mode of transmission food/water borne

Cholera•Description causes diarrhea,

dehydration; life-threatening if untreated•Responsible pathogen Vibrio cholerae

bacteria•Route of exposure gastro-intestinal•Mode of transmission often waterborne

Cryptosporidiosis•Description severe diarrhea; life-

threatening if immune system is impaired.•Responsible pathogen Cryptosporidium

parvum protozoa•Route of exposure gastro-intestinal•Mode of transmission waterborne

Botulism•Description causes paralysis; life-

threatening if untreated•Responsible pathogen Clostridium

botulinum bacteria•Route of exposure gastro-intestinal•Mode of transmission food/water borne;

grows in food

Typhoid Fever

•Description extreme fatigue, headache, joint pain, and a rash across the abdomen.

• Responsible pathogen  Salmonella Typhi

•Route of exposure gastro-intestinal•Mode of transmission food/water borne

Food borne bacterial diseasesc

Food borne bacterial diseases•Disease caused by consuming

contaminated food or drink.Microbes and toxic substance can contaminate foods.There are more than 250 known food borne disease.

•There are more than 250 known foodborne diseases.the majority of infections are caused by toxin,chemical containing the food.

Continue…•All foodborne microbe enter the body

through gastrointestinal tract and cause first symptom thre nausea,vomiting,abdominal cramp and diarrhea

•How bacteria get in food•Bacteria may be present when we

purchase them e.g, raw meat,seafood,and eggs are not sterile.

Which bacteria responsible for foodborne illness

•1_Campylobactor jejuni•2_Clostridium botulium•3_Clostridium perfringens•4_Escherichi coli O157.H7•5_Salmonella•6_Streptococus•7_Listeria monocyte•8_Staphylococus aureus

•Symptoms:fever,headache,musclepain,abdominal pain and nausea appear in 2_5 days after eating.

2_Clostridium botulium

•Found: soil,water,plants,intestinal tract of animal and fish.

•Transmission: bacteria produce toxin that cause illness.improperly canned food, and vaccum packaged.

•Symptoms:toxin effect the nervous system appear 18 to 36 hours double vision,dropping eyelid,trouble in speaking,swolling,breathing.

3_Clostridium perfringens

•Found: soil,dust,sewege and intestinal tract of human and animals
