Organism Disease(s) Symptoms of the Disease
Species: Trypanosoma brucei

(Genus: Trypanosoma)

– African Trypanosomiasis (Sleeping Sickness)

– Animal Tryponosomiasis

(Nagana)

The tsetse fly is the primary carrier of this parasite. The bite of this fly is extremely painful but if it infects the bite with the parasite then it will develop into a red sore called chancre. This is the first symptom.

Then the patient will experience the following symptoms:

  • Extreme fatigue
  • Fever
  • Irritability
  • Severe headaches
  • Aching muscles and joints
  • Swollen lymph nodes
  • Progressive confusion
  • Change in personality

In some cases, the patient will also develop rashes.

The symptoms do not show until 1 to 3 weeks after the infected bite and if not treated can lead to death within months.

Animals infected by the parasite first develop chancres but the difference in symptoms comes from the species of virus they are infected with. If the infected animal is infected with Trypanosoma brucei then the symptoms will be mild and self-heal.

Species: Entamoeba histolytica

(Genus: Entamoeba)

– Amoebiasis Early symptoms are mild and include diarrhea, stomach cramping and pain.

However; if amoebiasis develops further then it will become Amebic dysentery, a severe form of the infection.

At this stage, the patient will experience extreme stomach pains, bloody stool and fever.

In case of liver infection development of abscess (pus) occurs.

In rare cases, the infection will spread to other body parts like the lungs and brain.

Species: Ascaris lumbricoides

(Genus: Nematode)

– Ascariasis The roundworm responsible for this disease infects the intestines and lungs. In mild cases, there will be little to no symptoms. In severe cases, the symptoms will vary depending on the area infected.

Lungs: Symptoms experienced will be similar to asthma or pneumonia including persistent coughing, wheezing and shortness of breath.

Intestines: In case of mild infection the patient will experience slight abdominal pain, bloody diarrhea, nausea and vomiting. If the patient is severely infected with a large number of worms then the symptoms will include severe abdominal pain, weight loss, fatigue and expulsion of worms through vomit or stool.

Species: Phthirus pubis

(Genus: Pthirus)

– Pediculosis pubis (Crabs or Pubic lice) Symptoms for crabs include:

  • Itching
  • Inflammation
  • Irritation caused by itching
  • Black powder in underwear
  • Small spots of blood or small blue bruises caused by the lice’s bite on the skin on the thigh and abdomen.

Itching is the most common symptom of this disease and it worsens at night as the lice are most active at that time.

Species: Cryptosporidium sp.

(Genus: Cryptosporidium Tyzzer)

– Cryptosporidium infection (cryptosporidiosis) Early symptoms include:

  • Watery diarrhea
  • Dehydration
  • Lack of appetite
  • Weight loss
  • Stomach cramps or pain
  • Fever
  • Nausea
  • Vomiting
Species: Wuchereria bancrofti

(Genus: Wuchereria)

– Filariasis In some cases, the patients do not develop any symptoms and the patients that develop symptoms experience the following:

  • Inflammation of lymphatic vessels
  • High fever
  • Shaking chills
  • Body ache
  • Swollen lymph nodes
  • Accumulation of excessive fluid (edema) in affected areas.

Usually, the accumulation of fluids subsides when the symptoms wear off. Male patients can develop inflammation and painful swelling in genitalia, testes, sperm track and sperm ducts.

Species: Giardia intestinalis

(Genus: Giardia)

– Giardiasis This disease can lead to the development of a variety of symptoms affecting the intestines like:

  • Diarrhea
  • Foul-smelling and greasy stool
  • Dehydration
  • Stomach cramps and pain
  • Nausea
  • Weight loss

Other less common symptoms include fever, itching, hives and swelling.

  • Skin rash on feet
  • Fever
  • Coughing and wheezing
  • Abdominal pain
  • Diarrhea
  • Loss of appetite
  • Anemia
  • Weight loss
Species: Leishmania braziliensis

(Genus: Leishmania)

– Mucocutaneous Leishmaniasis

– Visceral Leishmaniasis

The most common symptom is painless ulcers on the skin.

  • Ulcers in the mouth, nose and lips
  • Runny or stuffy nose
  • Difficulty breathing
  • Nosebleeds
  • Weight loss
  • Weakness and fatigue
  • Fever
  • Enlarged spleen and liver

  • Shaking chills
  • Head and muscle ache
  • Tiredness
  • Nausea
  • Diarrhea
  • Vomiting

Malaria may also lead to anemia and jaundice. Severe symptoms include kidney failure, seizures, confusion and coma

Species: Pediculus humanus

(Genus: Pediculus)

  • Rapid breathing
  • Body and muscle aches
  • Rash

The patient develops a sudden onset of:

  • Fever
  • Headache
  • Pain behind eyes
  • Weakness
