| Resumen Las modificaciones en las prácticas agropecuarias y las condiciones climáticas y geográficas del trópico, asociadas con una amplia diversidad biológica, favorecen la propagación de enfermedades, la aparición de nuevos patógenos, o la reaparición de algunos ya controlados. Por lo tanto, y debido a que la leptospirosis es una zoonosis emergente asociada con inundaciones en zonas urbanas y rurales, que afecta mínimo 160 especies animales, y que el agua es un vehículo importante de transmisión, es necesario un trabajo interdisciplinar que minimice su presentación, y el impacto sobre la salud humana, animal y sobre el ecosistema (“Una Salud”). Por consiguiente, el objetivo de este ensayo fue analizar las implicaciones de las prácticas agropecuarias... |

| Leptospirosis caused by Leptospira interrogans is the most widespread zoonosis and a major public health problem worldwide. Based on light-scattering and absorption, quantification of leptospires using UV-VIS spectroscopy was used as an indirect counting technique by measuring the optical density and comparing this to automated direct counting using a counting chamber in combination with imaging and analyzing software. Two serovars, Bangkok and Copenhagenii, from log-phase growth were used for the establishment of standard curves. They were found to be linear and slightly different in gradient for each serovar. The ease, rapidity, and reliability of these two adapted and optimized counting techniques may provide a useful alternative enumeration technique... |

| The production of recombinant LipL32 protein using Escherichia coli has been used extensively for the development of vaccines and diagnostic tests for leptospirosis. However, E. coli has demonstrated limitations, including low yield and lack of post-translational modifications. In this study, rLipL32 was produced in eukaryotic expression system (Pichia pastoris) and evaluated the antigen by enzyme-linked immunosorbent assay (ELISA). The yield obtained from the culture supernatant reached 270 mg/L and ELISA showed an accuracy of 95.34%. In summary, the production of rLipL32 using P. pastoris did not impair the antigenic characteristics of this antigen and ensured its use for detecting the leptospiral antibodies in swine sera. |

| From February 1993 until October 1996, 547 blood samples were collected from mares with reproductive problems in six farms of the state of Rio de Janeiro, Brazil, and tested by the microscopic agglutination test (MAT) with live antigens for antibodies to seven leptospira serovars. A total of 235 positive reactions (42.96%) at a minimum serum dilution of 1:100 were observed against one or more serovars, which in comparison to other studies developed in Brazil, may be considered as a high prevalence. On mares with anti-leptospiral antibodies, the predominant serovar was icterohaemorrhagiae, reactive on 102 (43.40%) samples, followed by 64 (27.23%) reactions against bratislava, and 34 (14.47%) against pomona. The high prevalence of antibodies to serovar... |

| INTRODUCTION: leptospirosis is a zoonosis of worldwide importance. The disease is endemic in Brazil. This study was conducted to describe the clinical and laboratory presentation of leptospirosis in a metropolitan city of Brazil. METHODS: this is a retrospective study including 201 consecutive patients with leptospirosis admitted to tertiary hospitals in Fortaleza, Brazil, between 1985 and 2006. All patients had clinical and epidemiological data suggestive of leptospirosis, and positive laboratorial test for leptospirosis (microscopic agglutination test, MAT, higher than 1:800). RESULTS: a total of 201 patients were included, with mean age of 38.9 ± 15.7 years; 79.1% were male. The mean length from onset of symptoms to admission was 7 ± 3 days. The main... |

| This study was designed to estimate the prevalence of pulmonary radiograph abnormalities and describe the distribution of the patterns of radiographic alterations among patients hospitalized with leptospirosis. Chest radiographs of 139 patients hospitalized with leptospirosis in Couto Maia Hospital, in Salvador, Bahia, Brazil, between July, 1997, and July, 1999, were analyzed. The radiographs were requested soon after hospital admission, independent of the clinical manifestations of the patients. Only the first radiograph was considered. Pulmonary radiograph alterations were recorded in 35/139 patients (25.2%); 95% mid-point confidence interval = 18.5% to 32.9%. Among the patients with radiograph alterations, alveolar infiltrate was seen in 26/35 (74.3%).... |

| We report a case of leptospirosis that occurred after elective surgery involving tendon transfer and shoulder arthroscopy. The disease mimicked hospital infection after orthopedic surgery and was at first misdiagnosed as post-operative sepsis. The patient was 60 year old female that developed sepsis with hypotension, shock, bleeding, jaundice and renal insufficiency 4 hours after surgery. Shock treatment procedures were performed and broad spectrum antibiotic therapy was used with coverage for bacteria acquired in hospitals. A careful investigation was carried out by the Hospital Infection Control Service in search of the possible source of the infection. After clinical evaluation by a specialist in infectious diseases, the hypothesis of leptospirosis was... |

| Leptospirosis is an acute anthropo-zoonotic infection of worldwide significance caused by spirochaete Leptospira interrogans which has 23 serogroups and >200 serovars. Various factors influencing the animal activity, suitability of the environment for the survival of the organism and behavorial and occupational habits of human beings can be the determinants of incidence and prevalence of the disease. The disease was considered inconsequential till recently, but it is emerging as an important public health problem during the last decade or so due to sudden upsurge in the number of reported cases and outbreaks. Since isolation rate of the microorganism from clinical specimens is low due to prior indiscriminate use of antibiotics, serological techniques... |

| Leptospirosis is a re-emerging zoonosis with broad clinical spectrum and high mortality in severe forms. The aim of this study was to analyze clinical manifestations, laboratory findings, epidemiological data, and management in elderly patients with leptospirosis. Toward that end, we performed a descriptive analysis of 15 leptospirosis elderly cases (age 60-78 years) treated at the Clinic of Infectious Diseases of University Hospital - Pleven (1976-2012). Patients were serologically confirmed by microscopic agglutination test. Twelve cases (80%) presented with the severe form of leptospirosis. Co-morbidity (hypertonic diseases, chronic pulmonary diseases, chronic alcohol abuse, and diabetes) was registered in 13 cases. All cases had fever, oliguria,... |

| Record linkage and capture-recapture models were used to estimate the number of cases of human leptospirosis in the health district of Santa Maria, RS in southern Brazil. Twelve months of laboratory, hospital and epidemiological surveillance data were matched by name, age, residence and the month of diagnosis. Only laboratory-confirmed cases were considered. The record linkage revealed more than 20 times more cases than the official estimate for the health district, indicating a leptospirosis epidemic, with an annual incidence of more than 3 per 1,000 inhabitants and a case fatality of 0.37%. Severe cases were predominantly found through hospital records, overlapping to some extent with the epidemiological surveillance data, whereas less severe cases were... |

| Leptospirosis may have important complications, such as acute respiratory failure (ARF) associated or not with other organic dysfunction, with a high mortality rate. We report the characteristics and evolution of severe leptospirosis associated with ARF. During 10 years, 35 consecutive adult patients admitted in two general Intensive Care Units with severe leptospirosis and ARF, were followed up. Clinical characteristics, associated organic dysfunction and mortality were analyzed. Survivors were compared with non-survivors. The most frequent clinical manifestations were dyspnea, fever, myalgia, jaundice, hemoptysis and coughing. All patients presented ARF, needing mechanical ventilation, as well as other organic dysfunctions. The mortality rate was 51%.... |
