Interobserver reliability of Feline Dermatitis Extent and Severity Index (FEDESI) and Scoring Feline Allergic Dermatitis (SCORFAD) and the relationship between lesion scores and pruritus.

Background: Feline Dermatitis Extent and Severity Index (FEDESI) and Scoring Feline Allergic Dermatitis (SCORFAD) are scales used to assess lesion severity in cats with allergic dermatitis. Interobserver reliability has not been assessed for either.

Hypothesis And Objectives: To determine interobserver reliability for FEDESI and SCORFAD, and the relationship between lesion scores and pruritus.

Canine and Feline Cutaneous Epitheliotropic Lymphoma and Cutaneous Lymphocytosis.

Cutaneous lymphomas are divided into categories based on histologic evaluation of the skin and location of neoplastic lymphocytes. Epitheliotropic cutaneous lymphoma, also known as cutaneous T-cell lymphoma, is diagnosed when neoplastic lymphocytes show tropism for the epidermis and these cells infiltrate the epidermis and adnexae. In diagnosis of nonepitheliotropic cutaneous lymphoma, neoplastic lymphocytes are found mostly in the dermis and/or subcutis.

Case-control study of Staphylococcus lugdunensis infection isolates from small companion animals.

Background: Coagulase-negative Staphylococcus lugdunensis has recently been shown to cause invasive infections of people, which are similar in pathogenic effect to those caused by Staphylococcus aureus. Little is known about the pathogenicity of S. lugdunensis in companion animals.

Screening of Staphylococcus aureus, Staphylococcus intermedius, and Staphylococcus schleiferi isolates obtained from small companion animals for antimicrobial resistance: a retrospective review of 749 isolates (2003-04).

Companion animal staphylococcal isolate antibiograms were screened retrospectively to determine the frequency of methicillin-resistant (MR) infection by Staphylococcus aureus, Staphylococcus intermedius, and Staphylococcus schleiferi. Rates of MR were: S. aureus 35%, S.

Persistence and function of central and effector memory CD4+ T cells following infection with a gastrointestinal helminth.

Immunity in the gastrointestinal tract is important for resistance to many pathogens, but the memory T cells that mediate such immunity are poorly characterized. In this study, we show that following sterile cure of a primary infection with the gastrointestinal parasite Trichuris muris, memory CD4+ T cells persist in the draining mesenteric lymph node and protect mice against reinfection. The memory CD4+ T cells that developed were a heterogeneous population, consisting of both CD62L(high) central memory T cells (T(CM)) and CD62L(low) effector memory T cells (T(EM)) that were competent to produce the Th type 2 effector cytokine, IL-4.
