The remaining 49 strains were both susceptible to penicillin and avirulent, irrespective of the serotype.

These data provide additional insight into the difference between the virulent and avirulent strains of NDV.

Similar transcriptional differences were also observed when actively dispersed bacteria were compared with avirulent planktonic bacteria.

They are also avirulent in a mouse model.

These results indicate that recombinant viruses lacking the protease gene are avirulent but render protection from subsequent challenge.

These results thus suggest that virulent Listeria activates macrophages to induce autoreactive T cells while avirulent Listeria does not.

The results also suggest that chickens provide a mechanism for the selection of virulent viruses from an avirulent background.

Genes present in virulent bacterial strains but absent in avirulent close relatives can be of great biologic and clinical interest.

Overall, we provide evidence that protective immunity against cerebral cryptococcosis is established by means of an avirulent strain of C. neoformans.

The NBD mutant was avirulent by needle inoculation, but infectivity was partially restored by oral administration of IPTG to infected mice.

Thus, it is possible that Toxoplasma strains that are severely virulent in laboratory inbred mice are avirulent in some other mouse sub-species.

All of the recombinant viruses grew well in eggs, were avirulent in chicks, and protected animals against infection with a wild-type virus.

Conversely, one elicitin-producing P. parasitica isolate that is pathogenic on tomato and avirulent on tobacco still expresses parAl in the compatible interaction.

An avirulent and a highly virulent laboratory CSFV strain, and several recent field isolates from domestic pigs and wild boars were used.

In this study, we aimed at selecting avirulent environmental isolates with application potential in the prevention of E. tarda- and V. anguillarum-associated diseases.
