Comparing Resistant Microorganisms Isolated from Patients and Environment in an Intensive Care Unit  [PDF]
Quésia Souza Damaceno, Robert Iquiapaza, Adriana C. Oliveira
Advances in Infectious Diseases (AID) , 2014, DOI: 10.4236/aid.2014.41006

Background: Recently, the probable involvement of surfaces from the hospital environment as a disseminating source of resistant bacteria has been highlighted. The aim of the study was to compare resistant microorganisms isolated from inanimate surfaces, equipments and patient blood culture samples in an Intensive Care Unit from Belo Horizonte, Brazil. Methods: A cross-sectional study was performed from July to October 2009. Data sources were microbiologic samples from environment and patient blood culture. Duplicate samples were obtained by swabs from up to seven different touch sites around two different patients in four different days. Jointly with the environmental samples, bacterial isolates from an adult ICU patients’ routine blood cultures were obtained from hospital laboratory. The samples were identified, tested for sensitivity and compared by rep-PCR test to verify similarity. Results: Difference among the averages of Colony Forming Units was found within the environment samples (p < 0.004). In the environment were identified antibiotic resistant microorganisms such as Vancomycin resistant Enterococcus faecalis, imipenem and ciprofloxacin Pseudomonas aeruginosa and multidrug-resistant Acinetobacter baumannii. Similarities (60% -80%) were established among environmental and blood culture samples. Conclusion: The environmental sampling showed different averages of contamination of the surfaces and equipment. The similarity among the bacterial isolates of patients’ blood cultures and environmental samples reinforces the hypothesis of the horizontal transference of pathogens.

Advances in Infectious Diseases (AID) , 2015, DOI: 10.4236/aid.2015.51002
Abstract: Our aim was to determine the epidemiological characteristics, the resistance patterns and the spread of Gram negative bacteria related to colonization of patients in adult Intensive Care Units. Methods: A prospective cohort of patients colonized and/or infected with Gram negative bacteria was conducted at two adult ICUs from hospitals in Brazil (April 2012 to February 2013). Nasal, groin and perineum swabs were performed. Samples were incubated on MacConkey and cetrimide agar (48 h at 37) and identification tests (Vitek-BioMérieux), antibiogram (Bauer-Kirby method), Carba NP test, Polymerase Chain Reaction (PCR) and sequencing were performed. The patterns of resistant microorganisms were compared by rep-PCR (Diversilab). Results: There were 53 cases of colonization. In these cases, we identified imipenem-resistant Acinetobacter baumannii (51%), Pseudomonas aeruginosa (32%), Klebsiella pneumoniae ESBL (38%) or imipenem resistant (5.6%). The use of antimicrobials and medical devices were related to colonization (p < 0.05). The resistance patterns expressed by Klebsiella

Abstract: This research aimed at determining the pediatric patients profile at a School- Hospital, according to the variables sex, age, patients lenght-of stay, colonizing/infecting microorganisms, nosocomial infections (NI) and patiens outcomes. This was a prospective and descriptive epidemiological study developed in 2006 to which a database was developed in the SPSS program so as to type datas and analysed them afterwards. It was identified 668 patients, from whom, 53,7% were male, global avarage age was 5,1 years old and lenght-of-stay avarage was 10,1 days. It was colonized by resistant microorganisms 4,2% of the patients and 7,5% developed NI, being sepsis them most recurrent and Staphylococcus epidermides and Candida albicans the most evident microorganisms. There were 98,5% of discharge and 1,5% of deaths. This study reinforces the needing for continuous/active NI surveillance programes and the identification of (re) emergence of resistant bacterias so as to direct NI prevention and controle measures by those microorganisms.

Abstract: Com o propósito de avaliar a seguran a, a eficácia diagnóstica da biópsia pulmonar e comparar a possível ocorrência de complica es decorrentes da técnica, entre bezerros sadios e com broncopneumonia induzida, utilizaram-se dez bezerros (G1) sadios e vinte bezerros portadores de broncopneumonia, divididos em quatro grupos de cinco bezerros (G2 a G5), os quais foram biopsiados 12, 24, 48 e 72 horas após a inocula o com Mannheimia haemolytica, respectivamente. A presen a de crepita o grossa, som submaci o à percuss o e as altera es radiográficas auxiliaram no diagnóstico da broncopneumonia e localizaram a área pulmonar a ser biopsiada nos grupos G2 a G5. As altera es microscópicas, visualizadas nos animais do grupo G2 a G5, foram as de broncopneumonia fibrinopurulenta. Nos bezerros do grupo G1 as altera es relacionadas à técnica foram: tosse, epistaxe, dispneia mista, taquipneia e taquicardia. Cinco (25%) bezerros com broncopneumonia desenvolveram hemotórax após a biópsia e as altera es relacionadas à técnica foram: taquipneia, taquicardia, tosse, dispneia mista, apatia, mucosas pálidas e decúbito. Conclui-se que a biópsia pulmonar permite o diagnóstico de broncopneumonia em bezerros, contudo as complica es decorrentes da técnica limitam o seu uso apenas nas situa es em que os métodos convencionais n o tenham possibilitado o diagnóstico. PALAVRAS-CHAVES: Bezerros, biópsia pulmonar, broncopneumonia, Mannheimia haemolytica. The purpose of this study was to evaluate the safety and diagnostic efficacy of lung biopsy and to compare the possible occurrence of complications due to this technique in healthy calves and in calves with bronchopneumonia. Thirty Holstein calves were divided into a group of ten healthy animals (G1) and into four experimental groups (G2 to G5) of five calves each submitted to lung biopsy at 12, 24, 48 and 72 hours after intratracheal inoculation of Mannheimia. haemolytica, respectively. Lung crackles, dull sound on percussion of the lung area, and radiographic abnormalities were helpful in localizing the site for biopsy in group with bronchopneumonia. The microscopic abnormalities consisted of fibrinous bronchopneumonia these groups. In the calves of group G1, the alterations resulting from the procedure were cough, epistaxis, dyspnea, tachypnea, and tachcardia. Five calves (25%) with bronchopneumonia presented hemothorax after biopsy as well as tachypnea, tachycardia, cough, dyspnea, apathy, pale mucous, and decumbence. It was concluded that lung biopsy allowed to the diagnosis of bronchopneumonia in calves, however the severe
