A water permeability study of the isolated cat corneal endothelium was performed with the use of a newly designed Lucite chamber and modified experimental methods. The hydraulic conductivity of the cat endothelium was 9.3 ± 1.09 x 10~ cm. seer atmr. The Staverman reflection coefficient to NaCl of cat endothelium was 0.6. It was determined that the resistance to the passage of either water or sm...

We analyzed the genetic relatedness of blood culture isolates of Bartonella henselae from 2 cats of patients with cat-scratch disease at admission and after 12 months. Isolates from each cat at different times were clonally unrelated, which suggested reinfection by a second strain.

OBJECTIVE To identify dietary and environmental risk factors for hyperthyroidism in cats. DESIGN Case-control study. ANIMALS 100 cats with hyperthyroidism and 163 control cats. PROCEDURE Medical records were examined, and owners completed a mailed questionnaire. Data collected included information regarding demographic variables, environmental exposures, and diet, including preferred flav...

Cat scratch disease (CSD) is usually a mild selflimiting illness characterized by regional lymphadenitis occurring 2 to 3 weeks after an injury to the skin by a scratch from a cat. Recent evidence describes small, pleomorphic Gram-negative bacteria as the causative organisms.'`4 The main proponents of this hypothesis attempted to fulfil Koch's postulates in an animal model (armadillo), though o...

Hybridization among animal species has recently become more recognized as an important phenomenon, especially in the context of recent radiations. Here we show that complex hybridization has led to contrasting patterns of genomic composition among closely related species of the Neotropical cat genus Leopardus. We show strong evidence of ancient hybridization and introgression between the pampas...

We report a case of cat scratch disease caused by Bartonella henselae in Korea. A 25-yr-old woman developed left cervical lymphadenopathy with history of contact with a dog. The cervical lymphadenopathy persisted for 1 month and resolved gradually and spontaneously. Serologic test was not done during the acute stage of the disease. Immunofluorescent antibody test performed during the convalesce...

Optic neuropathy due to cat scratch disease is a relatively infrequent occurrence associated with macular star formation and is characterized by sudden painless loss of vision mostly unilateral. Bartonella henselae is well recognized as the etiologic agent in cat scratch disease. Ocular complications of the disease occur in up to 10% of patients and include neuroretinitis. Ocular bartonelosis i...

PURPOSE Bartonella henselae is the causal agent of cat scratch disease and one variation in its presentation is Leber neuroretinitis. The unilateral presence of exudation as a macular star and papilledema represent its most common presentation. METHODS Observational case report. A 7-year-old girl presented a sudden decrease of visual acuity and bilateral macular exudation (macular star) as we...
