| At that time, several groups of parasitologists interested in the microanatomy of filarial parasites examined the organisms with electron microscopes. |
| Here, then, was a possible explanation for the effectiveness of antibiotics against filarial nematodes. |
| The filarial life cycle consists of several developmental or larval stages in a mammal host and an intermediate stage in a mosquito which serves as host and vector. |
| Diethylcarbamazine and ivermectin, used for treating filarial worm infections, are absorbed from the intestinal tract. |
| At present, more than 200 million people are infected with filarial parasites. |
| In mammals filarial worms cause a group of infectious disorders including heartworm, elephantiasis, and river blindness. |
