Case report: Blindness associated with trematode infection in a green sea turtle, , of the northern Red Sea.

Spirorchiid blood flukes are widespread in sea turtles, causing disease and mortality in their populations, with high prevalence in several ocean basins. Besides being leading parasitic causes of sea turtle strandings in several parts of the world, these infectious agents can cause endocarditis, vasculitis, thrombosis, miliary egg granulomas, and aneurysms, which ultimately may compromise the survival of green sea turtles. More severe cases may also result in multifocal granulomatous meningitis or pneumonia, both of which can be fatal.

Quantitative analysis of magnetic resonance images for characterization of blood-brain barrier dysfunction in dogs with brain tumors.

Background: Blood-brain barrier (BBB) permeability can be assessed quantitatively using advanced imaging analysis.

Hypothesis/objectives: Quantification and characterization of blood-brain barrier dysfunction (BBBD) patterns in dogs with brain tumors can provide useful information about tumor biology and assist in distinguishing between gliomas and meningiomas.

Animals: Seventy-eight hospitalized dogs with brain tumors and 12 control dogs without brain tumors.

Spinal cord protothecosis causing paraparesis in a dog.

Protothecosis, an infectious disease caused by the green algae and , occurs sporadically in domestic animals and humans. Diagnosis of CNS protothecosis is based on neurologic signs that indicate multifocal nervous system lesions and that follow a period of chronic diarrhea and weight loss, cytologic observation of algae in fecal culture or histopathology, and detection of the agent by PCR assay of infected tissues. Here, we report a case of a paraparetic dog with CNS protothecosis that was diagnosed definitively antemortem using CSF cytology, PCR, and DNA sequencing.

Taenia multiceps brain cyst removal in two wild Nubian ibex (Capra nubianas).

Two wild adult Nubian ibex (Capra nubiana) were captured and admitted to the Hebrew University Veterinary Teaching Hospital with various neurologic signs, including alerted mentation, head tilt, and pathologic nystagmus. The lesion in the central nervous system was localized to the forebrain in one ibex and to the cerebellum of the other. Both ibex's were diagnosed with brain cyst using computed tomography (CT).

Aortic thromboembolism associated with Spirocerca lupi infection.

A 2-year-old male castrated Cavalier King Charles Spaniel was presented with paraplegia, cold caudal extremities and lack of femoral pulses. A 2cm long thrombus occluding the aortic trifurcation and a 3cm long abdominal aortic aneurysm with a thrombus were detected by ultrasonographic examination. The clinical and ultrasonographic findings were consistent with aortic thromboembolism.
