A field trial was carried out in the eastern part of the State of Minas Gerais (Brazil) of a vaccine containing killed promastigotes of five stocks of Leishmania. Tests with Montenegro antigen showed that a high proportion of the vaccinated persons became positive within three months, but circulating antibodies were not detected. A proportion of those(More)
Two naturally infected dogs (male and female) from Teófilo Otoni (MG-Brazil) were maintained for 18 months in our laboratory. Two other dogs, two months old males were infected with 1 x 10(6) promastigotes of MHO/BR/70/BH46 Leishmania (Leishmania) chagasi strain, endovenous route, and autopsied after 10 months and two years.

Brazilian army conscripts were vaccinated against American cutaneous leishmaniasis by using nonliving polyvalent promastigote Leish vaccine 5 or Leish vaccine 6 (vaccines with five or six Leishmania stocks) with or without Corynebacterium parvum. No statistically significant differences in lymphocyte stimulation indices were found between vaccinated groups(More)
The aims of this study were to evaluate the diagnostic value of ultrasonography and colour Doppler combined with fine needle aspiration (FNA) cytology for the detection of non-palpable axillary lymph node metastases in breast cancer patients. Forty patients with operable breast cancer (T1/T2), invasive carcinoma, not submitted to neo-adjuvant therapy,(More)
