1. Cat scratch disease presenting as axillary lymphadenopathy and a palpable benign mammary nodule mimicking a carcinoma
Abstract We present a case involving a 74-year-old woman with cat scratch disease characterized by an enlarged and hard axillary lymph node as well as a palpable breast nodule mimicking a carcinoma. The lymph node and the breast nodule were excised. The pathologic examinations revealed granulomatous lymphadenitis with gram-negative bacilli and an intraductal

2. Diagnóstico diferencial de cistos e linfadenite granulomatosa em linfonodos suínos
As infecções por Mycobacterium sp. têm grande importância na suinocultura devido às perdas econômicas decorrentes da alteração do destino de carcaças, tais como condenação total, aproveitamento condicional, ou mercado interno. As principais causadoras de linfadenite granulomatosa (LG), encontradas em matadouros frigoríficos, são as micobactéria

3. Hepatite granulomatosa em bovino causada por Mycobacterium avium subsp. paratuberculosis
Samples from intestines, liver, and lymph nodes were collected from a dairy steer with clinical suspicion of paratuberculosis. The samples were processed for histologic examination with hematoxylin-eosin and Zihel-Neelsen (ZN) staining for the detection of acid-fast bacilli (AFB), and submitted to immunohistochemistry (IHC). Macroscopic changes were observed

4. Study of the Mycobacterium avium horizontal transmission in swine / Estudo da transmissão horizontal de Mycobacterium avium em suínos
Haja vista a existência de quatro famílias de M. avium molecularmente distintas circulando na população de suínos do Sul do Brasil, a diferença de virulência constatada entre essas quatro famílias, a influência da virulência nos mecanismos de transmissão, as dúvidas existentes a respeito da existência e da importância da transmissão horizontal

5. Tuberculoid lymphadenitis due to Mycobacterium chelonei
An 8-year-old boy developed cervical lymphadenitis four months after an injection of dental anaesthetic. Histology of the lymphatic tissue showed a tuberculoid granulomatous reaction with scanty acid-fast bacilli. Mycobacterium chelonei was isolated in pure culture (NCTC 10882). The patient showed specific skin hypersensitivity to an extract of M. chelonei,

6. Detection and comparative analysis of persistent measles virus infection in Crohn's disease by immunogold electron microscopy.
AIMS: To determine the specificity of persistent measles virus infection in intestinal samples from Crohn's disease patients using quantitative immunogold electron microscopy. To compare the results with samples from ulcerative colitis, a granulomatous inflammatory control (tuberculous lymphadenitis), and a positive control. METHODS: Formalin fixed, paraffin

7. Compartmentalization of Immune Responses in Human Tuberculosis : Few CD8+ Effector T Cells but Elevated Levels of FoxP3+ Regulatory T Cells in the Granulomatous Lesions
Immune responses were assessed at the single-cell level in lymph nodes from children with tuberculous lymphadenitis. Tuberculosis infection was associated with tissue remodeling of lymph nodes as well as altered cellular composition. Granulomas were significantly enriched with CD68+ macrophages expressing the M. tuberculosis complex-specific protein antigen

8. Bartonella Infection in Animals: Carriership, Reservoir Potential, Pathogenicity, and Zoonotic Potential for Human Infection
Recent observations have begun to support a role for Bartonella spp. as animal as well as human pathogens. Bartonella spp. are vector-transmitted, blood-borne, intracellular, gram-negative bacteria that can induce prolonged infection in the host. Persistent infections in domestic and wild animals result in a substantial reservoir of Bartonella organisms in n

9. Fractalkine (CX3CL1) as an amplification circuit of polarized Th1 responses
Fractalkine (FKN, CX3CL1) is a membrane-bound CX3C chemokine induced by primary proinflammatory signals in vascular endothelial cells (ECs). Here we examined the role of FKN in polarized Th1 or Th2 responses. Proinflammatory signals, including LPS, IL-1, TNF, and CD40 ligand, induced FKN, as did IFN-γ, which had synergistic activity with TNF. IL-4 and IL-13
