Attempts to isolate virus from human trigeminal and facial ganglions.

Herpes virus hominis type 1 was isolated from the trigeminal ganglion (ganglion semilunare, gasservian) in three out of 20 randomly selected autopsies. Two of the three patients had been treated with immunosuppressive or cytostatic agents. Clinical signs of herpes infection were not observed during the previous 6 months. No virus was isolated from the facial ganglion (geniculate ganglion) in the same 20 cases. The findings are discussed in relation to the viral etiology of acute peripheral facial palsy.

Comparative responses of White Leghorn and New Hampshire chickens to experimental infections with Histomonas meleagridis and Heterakis gallinarium.

Experimental infections with Histomonas melegridis and Heterakis gallinarum were produced in young White Leghorn (W.L.) and New Hampshire (N.H.) chickens and Beltsville Small White turkeys (B.S.W.T.). Although the histomonads caused liver lesions and high mortality in B.S.W.T., infections in chickens were not fatal and were confined to the ceca. Cecal involvement in the W.L. was slightly more severe, but also more transitory, than in the N.H. With regard to length, survival, and reproductive capacity, the heterakids thrived best in the W.L. Furthermore, the W.L. had the greatest potential for disseminating Histomonas-bearing heterakid eggs. These findings are similar to those of a previous study with the same breeds of birds but with a different strain of W.L. Thus, the differences in responses according to breed were quite consistent, whereas any difference according to strain was insignificantly by comparison.

The wild turkey as a host for Heterakis gallinarum and Histomonas meleagridis.

Freshly embryonated eggs of Heterakis gallinarum gathered from naturally infected domestic turkeys and chickens developed the first 4 weeks essentially as well in young wild turkeys as in domestic poults, but then became progressively retarded and failed in most birds to result in females with fertile eggs. There was no significant difference in the prevalence or progress of infections with Histomonas meleagridis in the two kinds of turkeys, both of which differed from chickens only in that the latter had neither liver involvement nor mortality. In a second test, heterakids hatched from eggs stored 5-6 months at 4 C (comparable to overwintering) sustained very heavy losses in all birds, with greatly accelerated liberations of H. meleagridis, Few worms reached maturity and still fewer produced fertile eggs. In turkeys, and especially in wild turkeys, replacement of infective stages was so poor, that these birds were of no importance in contaminating the soil.
