13. Atypical presentation of sporotrichosis: report of three cases
Sporotrichosis occurs after fungal implantation of Sporothrix spp. in the skin, and is the main subcutaneous mycosis in Latin America. Here we describe three atypical cases of the disease. The first case report an extra-cutaneous occurrence of the disease with joint infection; the second one describes a patient with bilateral lymphocutaneous form of sporotri

14. Biologia comparada de carrapatos Amblyomma parvum (Acari: Ixodidae) do Brasil e da Argentina
O estudo das relações hospedeiro-carrapato pode fornecer uma gama de informações, incluindo aquelas necessárias para a prevenção de doenças parasitárias e/ou infecciosas. De ampla distribuição Neotropical, o carrapato Amblyomma parvum é capaz de se alimentar em várias espécies animais, inclusive o homem, além de ser potencial reservatório e/o

15. Effect of vitamin E levels on the cell-mediated immunity of broilers vaccinated against coccidiosis
Studies on the relationships between animal nutrition and immunity have sought reliable methodologies to measure responses. Cell-mediated immune response is similarly studied in humans. The cutaneous basophil hypersensitivity test (CBH) is one of the methods to measure that response and consists in the infiltration of inflammatory cells, particularly of lymp

16. LEISHMANIOSE TEGUMENTAR AMERICANA: uma abordagem farmacológica
The leishmaniasis (ACL) is a zoonotic disease whose etiologic agent, species of the genus Leishmania. And a disease of the skin and mucous membranes, primarily zoonotic involving a variety of wild and domestic mammals. Outbreaks of leishmaniasis occur by environmental changes due to deforestation, construction of dams, roads, mines, plant work areas, militar

17. Development of epitope specific recombinant peptides of the Rhipicephalus (Boophilus) microplus selected by Phage Display libraries / Desenvolvimento de peptídeos recombinantes epítopos específicos do Rhipicephalus (Boophilus) microplus selecionados por bibliotecas de Phage Display
Ticks are implicated in serious economic losses to animal production worldwide in the order of billions of dollars. Although many antigens have been in vaccine tests, none has been effective in the control of ticks, which justifies the development of new antigens as well as new vaccine strategies. Phage Display techniques have been widely employed to map epi

18. Further observations on clinical, histopathological, and immunological features of borderline disseminated cutaneous leishmaniasis caused by Leishmania (Leishmania) amazonensis
Leishmania (Leishmania) amazonensis has for some time been considered as the causative agent of two distinct forms of American cutaneous leishmaniasis (ACL): localized cutaneous leishmaniasis (LCL), and anergic diffuse cutaneous leishmaniasis (ADCL). Recently, a new intermediate form of disease, borderline disseminated cutaneous leishmaniasis (BDCL), was int

19. Clinical and immunopathological spectrum of American cutaneous leishmaniasis with special reference to the disease in Amazonian Brazil: a review
The wide variety of Leishmania species responsible for human American cutaneous leishmaniasis combined with the immune mechanisms of the host results in a large spectrum of clinical, histopathological, and immunopathological manifestations. At the middle of this spectrum are the most frequent cases of localized cutaneous leishmaniasis (LCL) caused by members

20. Antibody-mediated and delayed-type hypersensitivity reactions to Brucella skin test antigens in guinea pigs.
Cutaneous hypersensitivity responses to brucella antigens of different composition were studied in guinea pigs sensitized by infection with smooth brucella or immunization with killed rough brucella in adjuvant. These animals had circulating antibodies to smooth lipopolysaccharide or protein antigens, respectively. Intradermal skin tests, active cutaneous an

21. Impaired non-specific delayed cutaneous hypersensitivity in bird fancier's lung.
The relation between non-specific delayed cutaneous hypersensitivity and bird fancier's lung was investigated in 13 patients with the disorder. They were compared with 50 subjects who had no reason to have decreased non-specific delayed cutaneous hypersensitivity (control group) and 34 patients with pulmonary sarcoidosis. In addition, 13 patients with bird f

22. Delayed hypersensitivity cross-reactions between Sporothrix schenckii and Ceratocystis species in sporotrichotic patients.
Cutaneous delayed hypersensitivity to antigens prepared from Sporothrix schenckii and several Ceratocystis species, including C. stenoceras, C. ulmi, C. ips, and C. minor, was tested in 14 patients with known cutaneous sporotrichosis. Extensive cross-reactions were observed. Nonsporotrichotic people (controls) did not react to these antigens. The correlation

23. HL-A-Linked Human Immune-Response Genes
Genetic control of the response to specific natural-product antigens has been documented in three informative families. Families were selected on the basis of probands with tuberculosarcoidosis, chronic cutaneous moniliasis, and rheumatoid arthritis. An increased incidence of delayed cutaneous unresponsiveness was observed in each family. Positive associatio

24. Immunotherapy of experimental cancer by intralesional injection of emulsified nonliving mycobacteria: comparison of Mycobacterium bovis (BCG), Mycobacterium phlei, and Mycobacterium smegmatis.
Mycobacterium bovis (BCG), Mycobacterium phlei, and Mycobacterium smegmatis were each tested in emulsified form for their potency to cause regression of transplants of a syngeneic murine fibrosarcoma and of a syngeneic guinea pig hepatoma. On a weight basis, M. phlei and M. smegmatis were as effective as BCG in causing tumor regression. M. phlei and M. smegm
