ABSTRACT
From a total of 445 individuals, 17.1 per cent had antibodies against L. monocytogenes detected by the agglutination tube test. They were separated in seven groups: bloods donnors (n = 50), Hospital visitors (n = 40), frigorific workers (n = 28), aviculture workers (n = 87), herdsman (n = 31), agriculture students (n = 60) and street-sweepers (n = 51). L1/2a serotype was predominant. Individuals from urban areas (19.5 per cent) and those who had less contact with animals (21.7 per cent) had significantly positive serology when compared with individuals from rural areas (9.4 per cent) and those who had close contact with animals (13.2 per cent). The overall picture is individuals of more specialized occupations had more frequently (25.9 per cent) anti listeria antibodies similar to the results observed in developed countries where listeriosis is a public health problem in urban areas.

Na ausencia de insuficiencia cardiaca ou choque cardiogenico, o diagnostico de envolvimento cardiaco na leptospirose icterica pode ser baseado em alteracoes eletrocardiograficas. Devido ao frequente comprometimento multisistemico da doenca, algumas dessas alteracoes podem ser secundarias a disturbios metabolicos ou eletroliticos. Realizou-se um estudo para avaliacao do significado da enzima CK-MB elevada em casos suspeitos de envolvimento cardiaco. Sessenta e nove pacientes com leptospirose icterica foram estudados prospectivamente. Dez dos 16 casos com envolvimento cardiaco e 25 dos 53 pacientes sem envolvimento cardiaco CK-MB elevada (p>0,05). O valor medio de CK-MB foi maior no grupo com envolvimento cardiaco (p<0,05). Nossa analise indica que a presenca de CK-MB elevada no curso de leptospirose icterica nao e indicadora de envolvimento cardiaco.

A case of renal icterohemorrhagic leptospirosis involving a patient with acquired immunodeficiency syndrome (AIDS) is reported. Despite the low levels of CD4+ T lymphocytes, the clinical course of leptospirosis was similar to that observed in non-immunodepressed patients, and no worsening of AIDS occurred due to the infection by the spirochete. Serologic conversion was observed in the microscopic agglutination test, with maximum titer of 1:3,200. The patient had positive urine cultures for Leptospira interrogans for two months, whereas blood cultures were negative

In order to obtain data about clinical manifestations of symptomatic leptospiral infection in children, the authors reviewed 188 microscopic agglutination tests performed on sera of patients aged 0 to 12 years, made at the National Reference Laboratory of Leptospirosis (FIOCRUZ-RJ) from January 1983 to June 1991. Fifty two (27.6 per cent ) sera were positive. Twenty three (12.2 per cent ) children had serological evidence of acute infection. The most frequent signs and symptoms of these 23 cases were: fever (100 per cent ); myalgia (69.5 per cent ); headache (52.1 per cent ); jaundice (47.8 per cent ); vomit (34.8 per cent ); abdominal pain, hemorrhagic manifestations and impaired renal function (17.4 per cent ); conjunctivitis (13 per cent ); hepatomegaly (4.3 per cent )

Com o intuito de fornecer dados ao estudo da leptospirose humana, foram analisados 884 pacientes diagnosticados sorologicamente no Laboratório de Leptospirose da Fundaçäo Oswaldo Cruz - FIOCRUZ, no período de 1970 a 1982. Deste total, 775 estiveram internados em hospitais da cidade do Rio de Janeiro e 109 eram oriundos de outras cidades do Brasil. Sorologicamente, Icterohaemorrhagiae foi o sorogrupo mais freqüente, tanto para os pacientes do Grande Rio (76,4%), como para os demais (41,3%). No decorrer dos 13 anos, foram isoladas duas cepas de Icterohaemorrhagiae. Com relaçäo ao Grande Rio, observou-se uma freqüência maior da doença entre janeiro e abril (53,7%); o sexo masculino concorreu para 89,9% dos casos; e a faixa etária mais atingida compôs-se de indivíduos entre 16 e 45 anos (74,9%)
