A rare clinical presentation of transplacental transmission and subsequent abortion by Babesia (Theileria) equi in a mare

Although the main route of transmission of Theileria equi is through tick feeding, transplacental transmission is also possible and may lead to abortion, or to the birth of a sick or carrier foal. The aim of this study was to evaluate the role of T. equi as a cause of abortions in Israel and the risk of foals being infected at a young age. Eight aborting mares were serologically evaluated for exposure to T. equi via the immunofluorescence antibody test (IFAT) and their aborted fetuses were evaluated using PCR and qPCR. In addition, five mares and their foals (aged 4–6 months) from a highly endemic farm were tested for T. equi infection using IFAT, PCR and qPCR. Five of the eight aborting mares were seropositive for T. equi; however, none of the aborted fetuses was infected. All five mares from the endemic farm were subclinically infected with T. equi. Of their five foals, one was infected, with relatively high parasitemia and different parasite genotype than its dam’s, suggesting another source of infection. The results of this study suggest that transplacental transmission of T. equi is not common and does not appear to be a prominent cause of abortion in chronically infected mares.

Lysosomal Diseases

There are four lysosomal diseases of which the neuronal ceroid lipofuscinosis is the rarest. The clinical presentation and their characteric abnormal ultrastructure subdivide them into four types. These are known as the Infantile form (Santavuori-Haltia), Late infantile form (Jansky-Bielschowsky), Juvenile form (Batten-Spielmeyer-Voght) and the Adult form (Kuph's).An 8 year old Omani girl presented wth myclonic jerks since the age of 4 years, with progressive encephalopathy, mental retardation, ataxia and loss of vision. An ophthalmoscopy was performed followed by rectal suction biopsies (fig. 1). A previous sibling had died of an undiagnosed neurological disorder with a similar clinical picture.

Dementia is a major public health concern that afflicts an estimated 24.3 million people worldwide. Great strides are being made in order to better diagnose, prevent, and treat these disorders. Dementia is associated with multiple complications, some of which can be life-threatening, such as dysphagia. There is great variability between dementias in terms of when dysphagia and other swallowing disorders occur. In order to prepare the reader for the other articles in this publication discussing swallowing issues in depth, the authors of this article will provide a brief overview of the prevalence, risk factors, pathogenesis, clinical presentation, diagnosis, current treatment options, and implications for eating for the common forms of neurodegenerative dementias.
