What is the relationship between dog/cat fleas, tapeworms and rice in the stool?
Can humans get infected with dog tapeworms?
Fleas play a necessary role in the life cycle and reproduction of a certain type of tapeworm called Dipylidium caninum.
Humans can also be infected with Dipylidium caninum, but cats and dogs are the primary hosts cause cats and dogs more often swallow a flea.
The adult form of the tapeworm Dipylidium caninum lives in the small intestines of dogs and cats. The worm is made up of multiple segments. One at a time, the segments, full of eggs, are passed in the feces. While warm, the segments are active, but as they dry, they break open and liberate the eggs inside. A flea larva ingests the eggs. The egg develops into an immature form in the flea. When a dog or cat eats the flea (usually while the animal is grooming), the immature form of the tapeworm is released from the flea. This immature tapeworm then develops into an adult in the dog's or cat's intestine and the life cycle is completed.
The tapeworm D. caninum can not be passed directly from cat to cat or dog to dog. It must live part of its life in the flea.
Pets may be infected with other types of tapeworms in which the larval form of the parasite can be found in rodents, pigs, or fish, instead of fleas.
Do parasites cause morbidity or deaths?
Estimates of global morbidity and mortality rates
due to major human helminth (worms) infections.
The format of this table was modified from that presented in the orignal publication. Note that these diseases cause relatively few deaths, but that each causes significant morbidity, and it is the chronic and disabling nature of these diseases that have such an impact on human populations, especially in developing countries.

Protozoa species reported from human hosts.
Protozoa are the single celled organisms. There are 30,800 described species Protozoa living on planet Earth, but less then 70 are known to be parasitic inside human body.
In general, the protozoans are unicellular animals (although some have some plant or fungal features) that must be in liquid to be active. Many can survive drying by sealing themselves in protective coverings, but they aren't really active in those stages. This means that protozoans are found in water - they can be found in the oceans, in fresh water, or even really wet land environments like the undersides of thick leaf litter - and inside the watery environment of multicellular organisms. It is likely that you right now have protozoans living somewhere on you, although not as certain as having Monerans on or in you. Many of these "hitchhiker" protozoans do no or hardly any harm to their larger hosts, although some can produce various kinds of diseases. ...more
The protozoa comprise many different organisms with four classes that are of interest to us. These are the Sarcodina (amoebae), Ciliophora (ciliates, ) Zoomastigophora (flagellates) and the Apicomplexa (sporozoa). In each of these, individuals can be readily differentiated microscopically using a variety of anatomical and morphologic characteristics. One major difference between each class is the type of locomotion employed. In amoebae, movement is by pseudopodia or false feet, while ciliates utilize cilia and flagellates posses flagella. There is no notable means of movement in the Apicomplexa with most members being intracellular parasites .However, limited movement can be accomplished by contraction of intracellular microfilaments. http://www.cvm.okstate.edu/instruction/kocan/vpar5333/5333iia.htm
At least seven species of amoebae belonging to three genera are known to
parasitize humans. These include Entamoeba histolytica, E. hartmanni, E.
coli, E. polecki, E. gingivalis, Endolimax nana, and Iodamoeba butschlii.
All inhabit the large intestine except E. gingivalis which is found in
the mouth. At least three genera (Naegleria, Acanthamoeba, and
Hartmannella) usually free-living organisms, are known to also parasitize
humans and other mammals.
http://www.cvm.okstate.edu/instruction/kocan/vpar5333/5333iia.htm
The Apicomplexa are a taxonomic group that possess structures known collectively as an apical complex. The apical complex is found in the sporozoite and merozoite stage of all genera of malaria, piroplasms, coccidia (and related organisms) and Pneumocystis carinii.
The amoebae are common protozoa in most free-living situations. Most species posses both a trophozoite and cyst stages although exceptions occur. Some species have developed a parasitic mode of existence in various tissues and organs of animals and it is these that we will discuss in the next section.

Where can I get tested for parasites?
Can my doctor diagnose parasites?
There are only few laboratories in the USA, that we know of, which are competent to diagnose the presence of some parasites in the feces and in the intestines. BUT, not the presence of all species of parasites. Recognizing microscopic parasitic eggs in the feces is much harder job then finding bacteria, yeast or virus. "Good" labs are:
You might also find a competent physician in your area by contacting these
labs for that information.
It is generally cheaper and easier to do herbal or Coenzyme Q10 parasites
cleanse, then to diagnose the presence of parasites in the feces. If you do
have worms, parasites cleanse will get them out, and that is the best diagnoses.
Don't bother sending specimens to local laboratories.
What are the signs & symptoms of internal parasites?
There are over 400 different parasitic animals that can live isnside human body. From many different kinds of microscopic protozoa (amoeba) causing no symptoms, to large worms that can be several meters long, causing terrible joint pains.
Becasue there are so many different kinds
of parasites, there are very many different signs and symptoms associated with
having any of those animals inside of you.
Just to illustrate: tapeworm infection can cause Epileptic seizures, Ascaris
infection can cause Asthma and even death, Malaria infection can cause fever and
even death, sign of pin worms can be ichy nose, many different intestinal worms
can cause or be a cofactor in Constipation, Chronic fatigue, Eczema, Psoriasis,
... this list is really endless ...
But, to help you, here are just some most common signs that doctors are looking for:
Possible signs and symptoms of internal parasites:
These are only possible symptoms, and please keep in mind that not everyone that has a few of these symptoms should automatically make the assumption that they are infected; however, if you suspect infection or if you have been unsuccessfully treated for any health problem, it might be smart to do some herbal parasite cleansing.
