BACKGROUND: Trypanosoma cruzi infection via oral route results in outbreaks or cases of acute Chagas disease (ACD) in different Brazilian regions and poses a novel epidemiological scenario. In the Espírito Santo state (southeastern Brazil), a fatal case of a patient with ACD led us to investigate the enzootic scenario to avoid the development of new cases. At the studied locality, Triatoma vitticeps exhibited high T. cruzi infection rates and frequently invaded residences. METHODS: Sylvatic and domestic mammals in the Rio da Prata locality, where the ACD case occurred, and in four surrounding areas (Baia Nova, Buenos Aires, Santa Rita and Todos os Santos) were examined and underwent parasitological and serological tests...

We herein report the first domestic case of bacteremia caused by an intrinsic strain of colistin-resistant Acinetobacter. The Acinetobacter species was detected in the hemocultures in a febrile patient. The patient was a 65-year-old-man who was admitted to our hospital for laparotomic gastrostomy. The patient's antimicrobial susceptibility patterns were atypical; they were colistin resistant but not multiple drug resistant. A sequence analysis of rpoB identified the bacterium as an Acinetobacter genomic species 13BJ/14TU, which had only been previously reported in South Korea...

This article reports one of the rare cases of Abiotrophia defectiva endocarditis with no underlying valvular condition. A sixty-three years old man was hospitalized because of complicated respiratory sepsis with acute heart failure. Hemocultures and echocardiogram enabled the diagnosis of A. defectiva endocarditis. The clinical course was favorable under combined aminoglycoside and cephalosporin. The patient ultimately required valvular replacement. A. defectiva is a micro-organism part of the Nutritionnaly Variant Streptococci (NVS) associated with a high mortality rate and often resistant to antibiotics...

Orientia tsutsugamushi, which requires specialized facilities for culture, is a substantial cause of disease in Asia. We demonstrate that O. tsutsugamushi numbers increased for up to 5 days in conventional hemocultures. Performing such a culture step before molecular testing could increase the sensitivity of O. tsutsugamushi molecular diagnosis.

BACKGROUND: Trypanosoma cruzi is dispersed in nature through many transmission mechanisms among a high diversity of vectors and mammalian species, representing particular behaviors and habitats. Thus, each locality has a unique set of conditions underlying the maintenance of this parasite in the wild. The aim of the present study was to evaluate the life-cycle of T. cruzi in free-ranging coatis from the central region of the Brazilian Pantanal using a multi-factorial approach. METHODS: Three methodological blocks were used in the present study: (i) We evaluated T...

The etiological treatment of Chagas disease remains neglected. The compounds available show several limitations, mainly during the chronic phase. Lychnopholide encapsulated in polymeric nanocapsules (LYC-NC) was efficacious in mice infected with Trypanosoma cruzi and treated by intravenous administration during the acute phase (AP). As the oral route is preferred for treatment of chronic infections, such as Chagas disease, this study evaluated the use of oral LYC-NC in the AP and also compared it with LYC-NC administered to mice by the oral and intravenous routes during the chronic phase (CP)...

In oncologic patients fever is a non-specific clinical marker of different clinical settings. Procalcitonin (PCT) seems to be the most promising infection marker. We aimed to define the potential role of PCT as an earlier diagnostic marker in patients with fever and solid tumor. This retrospective study enrolled 431 patients. All of them performed hemoculture (HE) and basal PCT assessment (reference laboratory cut-off: ≤0.5 or >0.5 ng/dL) before starting antibiotic therapy. Gram positive (G+), negative (G-) or Fungi infection were detected...

114 strains isolated by blood cultures and transtracheal aspirations were typed: serotypes 3 and 4 were largely predominant and a 14-valent vaccine (1, 2, 3, 4, 6, 8, 9, 12, 14, 19, 23, 25, 51, 56) should cover 67 % of these strains and protect 53 % of our patients because the efficacy of the vaccine is evaluated at 80 %. A controlled clinical trial seems to be necessary. We did not isolate any penicillin-resistant strain but 14 % of our strains were resistant to tetracycline.

Fifteen specimens of the hemoculture and 89 specimens of the broncho-alveolar lavage were used in the study. Monocultures of gramnegative bacteria resistant to cefotaxime, cefepime, imipenem and meropenem were isolated from the specimens. The PCR method with detection of the results in the real time regimen (PCR test-system Litekh) provided detection of the beta-lactamase genes: bla(CTX-M-like) (72/104, 69.2%), bla(NDM) (6/104, 5.8%), bla(VIM) (49/104, 47.1%) and bla(OXA48-like) (59/104, 56.7%). There was identified correlation between the phenotype of resistance of Acinetobacter spp...

Trypanosoma cruzi is the etiological agent of American trypanosomiasis (Chagas' disease), which affects 6-7 million people worldwide, mainly in Latin America. It presents great genetic and biological variability that plays an important role in the clinical and epidemiological features of the disease. Our working hypothesis is that the genetic diversity of T. cruzi has an important impact on detection of the parasite using diagnostic techniques. The present study evaluated the diagnostic performance of parasitological, molecular, and serological techniques for detecting 27 strains of T...

This study reports loop-mediated isothermal amplification (LAMP) for rapid detection of methicillin-resistant Staphylococcus aureus from direct clinical specimens. Four primers including outer and inner primers were specifically designed on the two target sequences-femB to identify S. aureus and mecA to identify antibiotic-resistant gene. Reference strains including various species of gram-positive/gram-negative isolates were used to evaluate and optimize LAMP assays. The optimum LAMP condition was found at 63°C within 70 min assay time (include hybridization with FITC probe for 5 min and further 5 min for reading the results on the lateral flow dipstick)...

Trypanosoma terena and Trypanosoma ralphi are known species of the South American crocodilians Caiman crocodilus, Caiman yacare and Melanosuchus niger and are phylogenetically related to the tsetse-transmitted Trypanosoma grayi of the African Crocodylus niloticus. These trypanosomes form the Crocodilian clade of the terrestrial clade of the genus Trypanosoma. A PCR-survey for trypanosomes in caiman blood samples and in leeches taken from caimans revealed unknown trypanosome diversity and frequent mixed infections...

BACKGROUND AND AIMS: The introduction of Duke's criteria and the improvement of imaging methods has lead to an earlier and a more accurate diagnosis of infectious endocarditis (IE). The options for the best therapeutic approach and the timing of surgery are still a matter of debate and require a close colaboration between the cardiologist, the infectionist and the cardiac surgeon. METHODS: We undertook a retrospective, descriptive study, spanning over a period of five years (from January 1st, 2007 to December 31st, 2012), on 100 patients who underwent surgery for native valve infectious endocarditis in our unit...

The diagnostic of infections of blood flow using technique of hemofermentation (blood inoculation) is one of the most significant functions of laboratory of clinical microbiology. The effectiveness of the given technique depends on many factors, including criteria of evaluation of clinical significance of episode of bacteriemia and isolated microorganism applied by physician-microbiologist. The intelligent analysis of received results is needed. The physician-microbiologist has to determine if microorganism isolated from given blood sample, is a genuine agent of infections of bloodflow or it is only effect of contamination of analyzed sample at certain stage...
