características sociais, econômicas e territoriais distintas, podendo revelar um padrão peculiar nos casos de pandemias, sendo de grande importância a análise das características sociodemográficas e epidemiológicas para o planejamento contínuo de políticas de enfretamento.
O aumento na frequencia de isolamento e a disseminacao de enterobacterias com resistencia a diferentes antimicrobianos e atualmente preocupacao mundial. Paciente de 94 anos com leucemia linfocitica cronica foi admitida no Hospital Universitario em janeiro de 2010. Evoluiu a obito 21 dias apos hospitalizacao devido a piora clinica. Klebsiella pneumoniae produtora de beta-lactamases de espectro estendido (ESBLs) foi isolada de cultura de urina. Demonstrou resistencia a ceftazidima, ciprofloxacina, levofloxacina e ertapenem e sensibilidade a cefoxitina, cefepime e meropenem. Este e o primeiro relato de infeccao por Klebsiella pneumoniae portadora do gene bla kpc no estado de Mato Grosso do Sul, Brasil.
The increased frequency and dissemination of enterobacteria resistant to various antimicrobials is currently worldwide concern. In January 2010, a 94-year-old patient with chronic lymphocytic leukemia was admitted to the University Hospital. This patient died 21 days after hospitalization due to the clinical worsening. Klebsiella pneumoniae producing of extended-spectrum β-lactamases (ESBLs) was isolated of urine culture. This bacterium demonstrated resistance to ceftazidime, ciprofloxacin, levofloxacin, ertapenem and imipenem. Susceptibility to cefoxitin, cefepime, meropenem, colistin and tigecycline. This study reports the first case of infection by Klebsiella pneumoniae carrying the bla kpc gene in the State of Mato Grosso do Sul, Brazil.
Este estudo promoveu a detecção de DNA de Borrelia burgdorferi sensu lato em amostras de sangue e soro de pacientes com manifestações clínicas e epidemiologia compatíveis com a doença de Lyme‐símile brasileira ou síndrome de Baggio‐Yoshinari. Para tanto, foi feita triagem sorológica pelos métodos de Elisa e Western blotting e a identificação molecular de B. burgdorferi por meio da amplificação de um fragmento do gene conservado que sintetiza o gancho flagelar (flgE). Os resultados demonstraram sorologia positiva e, pela primeira vez, a presença de DNA de Borrelia burgdorferi sensu lato em humanos na Região Centro‐Oeste do Brasil. A análise genética das sequências dos isolados mostrou similaridade às sequências disponíveis no GenBank. Pela análise filogenética inferida pela sequência parcial do gene flgE, a cepa brasileira agrupou‐se com a sequência de B. burgdorferi sensu lato. Este estudo abre perspectivas promissoras e reforça a necessidade de estudos adicionais a fim de determinar as características epidemiológicas da doença, bem como o impacto da prevalência da borreliose brasileira no Estado de Mato Grosso do Sul, Brasil. We aimed to detect DNA of Borrelia burgdorferi in whole blood and serum samples of patients with clinical symptoms and epidemiology compatible with Brazilian Lyme‐like disease. Four patients with positive epidemiological histories were recruited for the study. Blood samples were collected, screened by serologic testing by ELISA and Western blotting and molecular identification of B. burgdorferi by amplifying a fragment of the conserved gene that synthesizes the hook flagellar (flgE). The results showed positive serology and for the first time, the presence of Borrelia burgdorferi sensu lato in humans in the Midwest region of Brazil. The resulting sequences were similar to GenBank corresponding sequences of Borrelia burgdorferi flgE gene. By neighbor‐joining the phylogenetic analysis, the flgE sequence of the Brazilian strain clustered in a monophyletic group with the sequence of Borrelia burgdorferi sensu lato under 100% bootstrap support. This study opens up promising perspectives and reinforces the need for additional studies to determine the epidemiological characteristics of the disease, as well as the impact of the prevalence of Brazilian borreliosis in Mato Grosso do Sul State, Brazil.

Infections caused by multidrug-resistant Klebsiella pneumoniae are difficult to treat and pose a serious threat to public health worldwide. Here, we describe the presence of carbapenemase-producing K. pneumoniae in intensive care units (ICU) of three major Mato Grosso do Sul hospitals located in the Midwest region of Brazil.A total of 165 K. pneumoniae isolates with reduced susceptibility to carbapenems as identified by the VITEK-2 compact system were studied. Antimicrobial susceptibility testing was performed using the disk diffusion method, as recommended by the Clinical and Laboratory Standards Institute, and the E-test method. The detection of carbapenemase was performed using the modified Hodge test and polymerase chain reaction.The blaKPC gene was identified in 88.1% (n=89) of the selected K. pneumoniae isolates from Beneficent Association of Campo Grande, 94.9% (n=34) of the isolates from the Regional Hospital of Mato Grosso do Sul and 95.2% (n=26) of the isolates from Maria Aparecida Pedrossian University Hospital. Resistance greater than 80% was observed against cephalosporins, aztreonam, ciprofloxacin and piperacillin/tazobactam. Carbapenemase-producing K. pneumoniae (Kp-KPC) isolates were considered important causative agents of urinary tract infections, pneumonia and bloodstream infections in ICU patients. While rarely reported in the literature, we documented three cases of meningoencephalitis caused by Kp-KPC.Our study documents the presence of Kp-KPC in three major Mato Grosso do Sul state hospitals, providing key national epidemiology data. This is an important mechanism of resistance in K. pneumoniae isolates from ICU patients and is associated with resistance to multiple classes of antimicrobial drugs.
