(18) Necropsy records, rabies antibody tests, and necropsy examinations performed by the authors indicate that migration of ascarid larvae usually is responsible for the abnormal behavior, and that rabies is an infrequent finding.

(4) On their descent they found droppings that seemed too large to be from any other insect and decided to return at night when the phasmids were known to be active.
(5) The bat gene product can also antagonize the lambda cI repressor as shown by the observation that lambda pR phasmids are virulent on a homoimmune lysogen.
(6) The region available for recombination spans the homologous sequence shared by the plasmid and the phasmid.
(7) After scaling the mount and not seeing any of the phasmids, the scientists resigned themselves to heading home empty-handed.
(8) By means of interspecific complementation of an Escherichia coli recA- mutation with phasmids containing a gene bank from an obligate methylotroph, Methylobacillus flagellatum (Mf), the recA+ gene from this bacterium was identified.
