Abstract: The present invention relates to an in vitro method for diagnosing and/or predicting hereditary cerebellar ataxia in a dog, and/or identifying a dog which is healthy carrier of hereditary cerebellar ataxia, comprising determining the presence or absence of an homozygous or heterozygous genetic variation in the arylsulfatase G gene sequence in a biological sample from said dog, as compared with the arylsulfatase G gene sequence of a healthy non-carrier dog, wherein the presence of said homozygous genetic variation indicates that said dog is or will be affected by hereditary cerebellar ataxia, and the presence of said heterozygous genetic variation indicates that said dog is healthy carrier of hereditary cerebellar ataxia, said dog being of a breed selected in the group consisting of American Staffordshire Terrier, American Pit Bull Terrier and Pit Bull type.

Abstract: An in vivo replicative and recombined porcine adenovirus characterized in that it comprises a heterologous nucleotide sequence inserted into the porcine adenovirus in conditions enabling the latter to be replicated in vivo and to express the inserted heterologous nucleotide sequence, and in that the adenovirus genome comes from a 3 or 5 serotype (PAV-3 or PAV-5) adenovirus. Insertion occurs in a non-essential zone of the E3 region, preferably with deletion of said zone. The invention also relates to a recombined porcine vaccine comprising one such porcine adenovirus. The invention further relates to a serotype 3 or 5 porcine adenovirus vector that is replicative in vivo and is deleted in a non-essential region of the genome thereof. The invention also relates to a DNA fragment comprising all or part of the referenced SEQ ID NO.5 nucleotide sequence.
