| isolation and preliminary characterization of a 48-kilodalton metalloproteinase from the excretory/secretory components of the frontal glands of porocephalus pentastomids. | porocephalid pentastomids possess prominent paired frontal glands which discharge secretion through large ducts onto the cuticle in the region of the cephalothorax. we have purified and partially characterized a 48-kda protein with proteolytic activity from the major secretory cell type in the glands of porocephalus crotali, removed from the tissues of rodent intermediate hosts. it comprises 30% of total protein isolated from secretory droplets. antibody to the enzyme was detectable at 50 days p ... | 1991 | 1852177 |

| presence of porocephalus clavatus (arthropoda: porocephalidae) in peruvian boidae snakes. | the pentastome species, porocephalus clavatus, has been found to infect the lungs of two species of snakes in the family boidae family (boa constrictor and epicrates cenchria). the individual of b. constrictor was collected in the amazonian rainforest of departamento loreto, peru. the e. cenchria was recovered from the pet trade in lima, peru's capital city. a total of 22 p. clavatus were collected and examined from these two snakes. this is the first report of p. clavatus in peru. the morpholog ... | 2011 | 21531511 |
