Cat scratch disease: evidence for a bacterial etiology. A retrospective analysis using the Warthin-Starry stain.

97 cases of acute necrotizing granulomatous lymphadenitis (so called "reticulozytärabszedierende Lymphadenitis") were examined retrospectively with the Warthin-Starry stain, in order to detect bacteria in patients with cat-scratch disease (CSD). 27 patients with CSD were found and among those, bacteria were demonstrated in 4. The organisms were pleomorphic rods of about 3 micron length and occurred in clumps within foci of fresh necrosis. We found the organisms in a much lower percentage than has been described in the literature. The reasons may be that many of our patients had antimicrobial treatment prior to the biopsy and that step-sectioning of the specimen may be necessary in order to detect fresh lesions. Our findings seem to confirm the observation that CSD may have a bacterial aetiology.

A subcortico-cortical cholinergic system is affected in Parkinson's disease.

CAT activity was decreased in the frontal cortex and the substantia innominata of parkinsonian subjects, post-mortem. The decrease was greater in the frontal cortex of parkinsonians with dementia. The density of muscarinic cholinergic receptors increased in the cortex. This increase was inversely correlated with tremor. The effects on these parameters of both neuronal degeneration and anticholinergic therapy are discussed.

Adult-onset motor neuron disease in three cats.

Motor neuron diseases of domestic animals have rarely been described. Three cats with adult-onset, chronic, progressive generalized muscle weakness characterized initially by trembling on exertion and later by extreme difficulty in walking, cervical ventroflexion, dysphagia, and marked muscle atrophy were elevated. Spinal reflexes were evident early but were nondetectable as the disease progressed. Electromyography revealed fibrillation potentials, with nerve conduction velocities within the reference range. Histologic examination of muscle specimens revealed denervation. Marked neuron loss and gliosis were detected in the ventral horns of the spinal cord, with atrophy of ventral nerve rootlets. Less dramatic neuron loss was seen in brain stem motor nuclei. Electron microscopic examination of the ventral horns disclosed hypertrophied astrocytes, with densely arrayed intermediate filaments, swollen axons with large filamentous accumulations, and many macrophages with lipofuscin-like inclusions. Clinical and pathologic findings were consistent with a progressive neurodegenerative disease affecting spinal and some bulbar motor nuclei.

Zoonotic diseases of cats.

As veterinarians, our responsibilities do not end with the care of our patients. The welfare of our clients and their families depends on our ability to detect and control potentially zoonotic diseases in their pets. Because some of these zoonoses can have devastating effects on the development of the unborn fetus or on family health in general, discussion about these diseases between veterinarian and client is often emotionally charged. Under such circumstances, the offering of inaccurate and erroneous information by the veterinarian can have drastic consequences. It is likely that other zoonotic diseases of domestic pets will be identified in the future, especially those that can cause opportunistic infections in debilitated and immunodeficient persons. In the meantime, the potential hazards of cat ownership can be significantly reduced through an increased understanding of feline diseases and an improved level of health care for our feline patients.

Pitfalls and fallacies of cat scratch disease serology: evaluation of Bartonella henselae-based indirect fluorescence assay and enzyme-linked immunoassay.

The diagnostic value of the detection of immunoglobulin G (IgG) and IgM by Bartonella henselae-based indirect fluorescence assay (IFA) and enzyme-linked immunoassay (EIA) for the diagnosis of cat scratch disease (CSD) was evaluated. The IFA was performed either with B. henselae that was cocultivated for a few hours with Vero cells or with noncocultivated B. henselae as the antigen. Additionally, the performance of a Bartonella PCR hybridization assay based on the 16S rRNA gene was determined and compared with those of the serologic assays. The study group consisted of 45 patients suspected of suffering from CSD by fulfilling one or more of the classical criteria. The specificities of the immunoassays were set at > or = 95% by analysis of sera from 60 healthy blood donors. It is shown that the sensitivities of the IgG assays are very low (40.9% for the IFA with noncocultivated B. henselae as antigen) and that those of the IgM assays are higher (71.4% for the EIA) for patients who fulfilled two or more criteria for CSD. The IgM EIA showed the highest sensitivity: 71.4% in patients with two or more criteria for CSD and 80.6% for patients with a positive Bartonella PCR result. The results indicate that the specificities of both IFA and EIA IgG serologies and the sensitivity of the IFA IgM serology need to be improved. The PCR hybridization assay showed a sensitivity of 86.4% for patients who fulfilled two or more criteria for CSD and 100% for seven patients who fulfilled three or more criteria. The kinetics of IgG and IgM antibody production were studied in 18 patients with CSD on the basis of a positive B. henselae IFA IgM serology. The results indicate that there is no standard course of anti-B. henselae IgG and IgM production in patients with CSD, because some patients produced high levels of both IgG and IgM, others produced only high levels of IgM, and a few patients produced only low levels of antibodies.

Partial nucleotide sequencing of the mecA genes of Staphylococcus aureus isolates from cats and dogs.

Methicillin-resistant staphylococci (MRS) pose a challenge to clinicians and health administrators in human medicine, but MRS infections in cats and dogs are not perceived as a problem in veterinary medicine. Ten methicillin-resistant staphylococcal isolates obtained from healthy and diseased cats and dogs were subjected to partial DNA sequencing of the mecA gene. Sequence analysis shows that MRS isolates from both healthy and diseased cats and dogs can harbor the mecA gene. The mecA genes of animal isolates were identical to that found in human MRS strains, and therefore the possibility of zoonotic transfer must be considered.

Cat-scratch disease: an unusual presentation.

A 2-year-old child was found to have mesenteric lymphoadenopathy during investigation of a fever of unknown origin. The lymphadenopathy persisted at follow-up 2 months later. Workup for an infectious etiology was negative. A laparotomy and excisional biopsy was performed to eliminate lymphoma. Pathology showed enlarged lymph nodes containing granulomas with giant cells and central caseating necrosis. Warthin-Starry staining showed cat-scratch bacilli within the necrotic material. Cat-scratch disease is a well-recognized cause of regional adenopathy in children and usually resolves without treatment. Intraabdominal involvement, consisting of hepatic and splenic lesions, often associated with retroperitoneal adenopathy, has been reported. Isolated mesenteric adenopathy is an unusual presentation of this disease but should be included in the differential diagnosis of intraabdominal lymphadenopathy.
