Fundus examinations showed bilateral "cherry-red spot" appearance, multiple confluent cotton wool spots, and widespread arterial occlusion. Laboratory studies showed(More)

Borrelia garinii spirochete was detected for the first time in Ixodes ovatus tick ectoparasitized on stray cat in Taiwan. The genetic identity of this detected spirochete was determined by analyzing the gene sequence amplified by genospecies-specific polymerase chain reaction assays based on the 5S-23S intergenic spacer amplicon (rrf-rrl) and outer surface(More)
Ocular ischemic syndrome (OIS) is characterized by ocular symptoms and signs that are secondary to severe carotid artery obstruction. We report a 69-year-old man who suffered from progressively blurred vision in both eyes. Fundus examination showed scattered areas of retinal hemorrhage, some with a white center, in both eyes.

Babesia gibsoni was firstly identified in Rhipicephalus sanguineus ticks infested on dogs in Asia. A total of 1195 ticks collected from veterinary practitioners and pet clinics were examined for Babesia by nested-polymerase chain reaction assay based on the 18S small subunit ribosomal RNA (ssrRNA) gene. Babesia infection was detected in nymph, male and(More)
