Elderly persons, i.e., those >65 years of age, were affected most by C. diffi cile infections; this age group accounted for 1,506 (65%) of all cases (n = 2,306) in 2006. The 45to 64-year age group had the next highest number of cases, 451 (20%). Men and women were affected equally in the different age groups; slightly more women (n = 805) than men (n = 701) with C. diffi cile infection were >65...

A new oleanan-type triterpene and three new cincholic acid glycosides were isolated from Peruvian "Una de Gato" (Cat's claw, plant of origin: Uncaria tomentosa), a traditional herbal medicine in Peru. Their structures were determined by spectroscopic analysis.

Cat-scratch disease (CSD) is mostly preventable. More information about the epidemiology and extent of CSD would help direct prevention efforts to those at highest risk. To gain such information, we reviewed the 2005-2013 MarketScan national health insurance claims databases and identified patients <65 years of age with an inpatient admission or outpatient visit that included a CSD code from th...

An inverse relationship has been proposed between exposure to high quantities of cat allergen at home and both asthma and cat allergy. First- and second-grade children from Luleå, Kiruna, and Piteå, Sweden participated in an asthma questionnaire study (n = 3,431) and incidence was evaluated over the next 3 years. Skin testing was performed on the children in Luleå and Kiruna (n = 2,149). The st...

● RESULTS: A number of novel Bartonella species have been identified over the past decade. Of these, Bartonella henselae, the etiologic agent in cat scratch disease, is most often associated with ocular complications, which may include Parinaud oculoglandular syndrome, neuroretinitis, and focal retinochoroiditis. Although cat and flea exposure appear to be the main risk factors for contracting ...

Benign lymphoreticulosis (cat scratch disease, CSD) may have a clinical course that varies from the most common lymphadenitis localized in the site of inoculation, preceded by the typical "primary lesion," to a context of severe systemic involvement. Among these uncommon clinical aspects, there is mammarian granulomatous lymphadenitis which may appear as a mastitis or a solitary intraparenchyma...

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...
