| Abstract: Here we describe an eight-year-old miniature schnauzer (MS) dog from Brazil with Persistent Mullerian Duct Syndrome (PMDS) and the single base pair substitution in AMHR2 exon 3, first detected in this breed in the USA. This finding is evidence of mutation dissemination to South America. In PMDS, a type of XY Disorder of Sex Development (DSD), dogs with a male karyotype and external phenotype also have a uterus, oviducts, and a cranial vagina internally. Approximately half of PMDS MS are unilaterally or bilaterally cryptorchid and many develop pyometra and/or Sertoli cell tumor. Bilateral Sertoli cell testicular tumors were present in this case, and the dog died a few days after surgical castration and hysterectomy. Although the karyotype was... |

| ABSTRACT The birth of fraternal twins is a characteristic frequently observed in callitrichids. Cytogenetic studies have demonstrated hematopoietic chimerism in marmosets with the occurrence of two cell lines 2n=46,XX/46,XY in females and males co-twins, without phenotypic changes. Amplification by PCR have also been used to verify the presence of the SRY gene in female chimaeras. Our aim was to verify the occurrence of chimerism in Callithrix sp. individuals considered as hybrids according to their intermediate phenotypes between C. jacchus and C. penicillata. Blood samples from 37 Callithrix sp. individuals were collected. Hematopoietic chimerism 2n=46,XX/46,XY was detected by cytogenetic analysis in five individuals, three males and two females. A... |
