    Abstract "The revised third edition of Pathology of Pet and Aviary Birds delivers a comprehensive reference to gross and microscopic lesions found in birds, as well as the implications of these diseases. This third edition includes improved coverage of normal anatomy and of advanced diagnostic techniques, including special stains, immunohistochemistry, in situ hybridization, and molecular diagnostics. The authors offer an extensive collection of more than 1200 high-quality, full-color images. New chapters cover the postmortem examination; gross and microscopic anatomy; advanced diagnostics; cytology. Specific chapters address diseases of passerines, Columbidae, and raptors, and other chapters are intuitively organized by body system. Pathology of Pet and Aviary Birds is an essential resource for veterinary pathologists and pathology residents, and will also benefit avian practitioners and veterinary students with an interest in diseases of pet birds and birds in avicultural collections. As many diseases in captive birds also manifest in wild birds, the book will appeal to those interested in the diseases and pathology of wild birds"--

    Abstract A 27-year-old female white-faced saki (Pithecia pithecia) died following an onset of vomiting and ptyalism. Necropsy revealed lesions of suppurative ventriculitis, choroid plexitis, periventricular encephalitis and meningitis with intralesional gram-positive coccobacilli and paired rods. The saki also had suppurative to mononuclear hepatitis, mild intestinal crypt necrosis, proliferative glomerulonephritis, aortic arteriosclerosis, pulmonary interstitial fibrosis, chronic mild epicarditis, ovarian medullary arteriopathy and a focal superficial cerebral fibrotic nodule with surrounding chronic mixed cell inflammation. Listeria monocytogenes was cultured from liver and spinal cord. Intralesional Listeria bacteria were immunolabelled in brain sections and RT-PCR of brain tissue detected L. monocytogenes. Whole genome multilocus sequence typing characterized the cultured bacterial isolates as sequence type 6 and clonal complex 6. A database search for related clinical and food listerial outbreaks identified genetically related isolates but, because these isolates were more than 20 alleles distant from the saki isolates, they were not a related cluster. Reports of listeriosis in non-human primates are infrequent, and when infections do occur, they tend to be haematogenous with the propensity to cause meningoencephalitis. This saki likely ingested environmental L. monocytogenes, which resulted in disease that may have been facilitated by pre-existing co-morbidities and age.

    Abstract Case summary: An 11-year-old female spayed domestic medium-hair cat presented for dental prophylaxis, at which time no oral mass was appreciated. Fifteen days after a dental cleaning, a mass expanding the oral mucosa of the rostral mandible was identified. An incisional biopsy revealed that the oral mucosa was infiltrated by neoplastic round-to-spindloid mesenchymal cells arranged in streams and small, dense aggregates consistent with an undifferentiated sarcoma. The patient was managed medically for approximately 6 months following the diagnosis, but, owing to declining health, euthanasia was elected and a post-mortem examination was performed. On post-mortem examination, the previously described neoplastic cells were infiltrating the rostral mandible and had metastasized to the right submandibular lymph node. Immunohistochemistry performed during the postmortem examination found that neoplastic cells were positive for Iba-1, CD18 and CD204, and negative for MUM-1, S100, Melan-A and E-cadherin, favoring a diagnosis of oral histiocytic sarcoma. Although recently recognized in cats, feline oral histiocytic sarcoma is rare, the tumor's immunohistochemical profile is unstandardized, and the tumor's behavior and prognosis are unclear. The diagnosis is challenging if small incisional biopsies are submitted and the neoplasm is poorly differentiated. This case report discusses the clinical, macroscopic, microscopic and immunohistochemical features of oral histiocytic sarcoma in a cat with mandibular invasion and submandibular lymph node metastasis.
    Relevance and novel information: Feline primary oral histiocytic sarcoma is rare and tumor behavior and prognosis are unclear. This report broadens the immunohistochemical features of the tumor and recognizes mandibular invasion and submandibular lymph node metastasis.

    Abstract A 6-month-old mixed breed dog was referred for evaluation of a potential disorder of sex development (DSD) and lower than expected energy level. Genitourinary examination revealed ambiguous external genitalia, hypospadias, and a subtle pouch of skin that resembled an empty scrotum. Corrective surgery was planned and subsequently aborted after cyanosis was identified preoperatively and an arterial blood gas analysis by co-oximetry identified increased methemoglobin (MetHb) concentration (35%, normal <2%) with normal arterial oxygen tension. Ensuing investigations confirmed hereditary methemoglobinemia caused by cytochrome b₅ reductase (CYB5R) deficiency via molecular genetic (Arg219Pro homozygous variant in CYB5R3 gene) and biochemical (cytochrome b₅ reductase enzyme activity of 8% [normal, 100% activity] testing. Karyotyping and molecular analysis of sex chromosomes revealed the dog was genetically female with a normal female karyotype (78,XX), and was negative for the Y-linked SRY gene and positive for the X-linked androgen receptor gene. Methylene blue (MB, 3.3 mg/kg per os [PO] q24 h) was administered and the MetHb concentration decreased to 9% within 14 days. Urogenital revision surgery proceeded without complication and the dog was maintained on MB (3-4 mg/kg PO q24 h) long-term without adverse effects. This is the first report to describe the use of PO MB to decrease MetHb concentrations in a dog with CYB5R deficiency in preparation for anesthesia and highlights its potential as a viable alternative to the intravenous formulation for elective procedures. In addition, this report describes the clinical, molecular, imaging, surgical, and macroscopic and microscopic pathological features of a dog with SRY-negative, 78,XX testicular DSD.

  7. Article: Streptococcus equi ssp. zooepidemicus meningoencephalomyelitis in a southern tamandua (tamandua tetradactyla) associated with a raw horsemeat diet

    Abstract A 1-y-old female southern tamandua (Tamandua tetradactyla) presented with vomiting, hyporexia, and neurologic signs. Magnetic resonance imaging revealed contrast-enhancing material within the lateral and fourth ventricles and a T2 hyperintense cerebellar lesion, consistent with meningoencephalitis. The tamandua rapidly declined and was euthanatized. On gross postmortem exam, the tamandua had diffusely injected leptomeninges, opaque fluid in the fourth ventricle, and subdural brainstem and spinal cord hemorrhage. Histologically, there was regionally hemorrhagic and multifocal fibrinosuppurative meningoencephalomyelitis, ventriculitis, choroid plexitis, cerebellar folia necrosis, ependymitis, radiculoneuritis, and abundant intralesional gram-positive cocci. Streptococcus equi ssp. zooepidemicus was cultured from brain, cardiac blood clot, and multiple samples of horsemeat collected from the animal's diet. This is the first report of streptococcal meningoencephalomyelitis in a southern tamandua. The route of infection was likely gastrointestinal inoculation, which may have implications for the routine practice of feeding diets containing raw meat to insectivores.
