Parasite: part 4 Flashcards
Symptoms from giardia lamblia
Most people infected with Balantidium coli => no symptoms. ACUTE SYMPTOMS Diarrhoea Greasy stools that tend to float Stomach or abdominal cramps Upset stomach or nausea/vomiting Dehydration (loss of fluids)
Treatment and diagnosis of giardia lamblia
Stool exam (cysts or trophozoites) Treatment: metronidazole/tinidazole
How do you catch trichomonas compared to other flagellate giardia lamblia
Trichomonas= Exclusively Transmitted sexually giardia lamblia= water- borne
How common Is trichomoniasis
It is estimated to be the most common, curable, non-viral sexually transmitted infection in the UK, with nearly 6000 new cases per year.
Where the infection of trichomoniasis
In women the organism is found in the vagina, urethra and paraurethral glands; in men infection is usually of the urethra.
Symptoms of trichomoniasis infection
F: 10-50% none. Vaginal discharge, vulval itching, dysuria, or offensive odour (non-specific) Male: 15 to 50% of men are asymptomatic. discharge and/or dysuria.
Complication of trichomoniasis infection
Detrimental outcome on pregnancy and is associated with preterm delivery and low birth weight.
Implication of trichomoniasis for HIV+
There is growing evidence that trichomonas infection may enhance HIV transmission and there may be an increased risk of TV infection in those that are HIV positive.
Diagnosis and treatment of trichomoniasis
Diagnosis Microscopy: Detection of motile trichomonads in swab/urine- Trichomonas Rapid Test Treatment metronidazole
Types of metazoa
Roundworms, flatworms, flukes
What type of organisms are metazoa
Metazoa= helminths Complex muticellular parasites
What are the lifecycles of metazoan like
Cycles may involve insect vectors and intermediate hosts
T/f few metazoan infections are zoonoses
T For most, humans are the definitive host - few are zoonoses (acquired from animals)
T/f you can consume a worm and have a helminth infection
F: Adult worms cannot multiply in man - number of adults related to infection (eggs cause the problem) (lay eggs/microfilaria, larvae)
Highest burden of helminth infection what age
0-10
