“…The highest infection prevalence was respiratory, mounting 27.6% of the infection cases, and the most present organism was P. aeruginosa, identified in 37.5% of the infected samples. In Fortaleza-CE [Brazil], the results found by Menezes et al (23) were not very different from the above mentioned in a study performed at the Hospital Geral de Fortaleza's isolates from January to December 2002. The most frequent tracheal secretions bacteria were P. aeruginosa (16%) and K. pneumoniae (15%).…”

Objectives: Pseudomonas aeruginosa is an increasingly prevalent opportunistic pathogen in hospital infection cases. Its high resistance rates to many antimicrobials has given this microorganism a relevant role among other highly prevalent bacteria involved in nosocomial infections. This study aimed to analyze epidemiologic characteristics of P. aeruginosa and to evaluate its susceptibility to antimicrobial agents at Hospital das Clínicas of the Universidade Federal de Pernambuco Methods: A retrospective study was performed based on the registry book of miscellaneous secretions from the bacteriology laboratory of the Hospital das Clínicas involving the period between January and June 2008. Among the secretions registered, were identified the positives samples for P. aeruginosa, whose origin was analyzed, as well as its susceptibility profile to routinely used in our laboratory antimicrobials. Results: The bacteria most frequently isolated from miscellaneous secretions bacteria were P. aeruginosa (26%) and S. aureus (25%). P. aeruginosa was mainly isolated from respiratory infections, with 33% of positive samples for this organism from tracheal secretions and 21% from nasal. The most effective antimicrobials against P. aeruginosa were: amikacin, imipenem, meropenem and aztreonam. Conclusions: These results show a high prevalence of P. aeruginosa in the Hospital das Clínicas of the Universidade Federal de Pernambuco. Despite featuring high resistance rates to older antimicrobials, as cephalosporins first and second generations and chloramphenicol, this pathogen showed good susceptibility to agents routinely used in this hospital.

“…CoNS are regularly shed onto the hospital environment by patients and medical personnel, whereupon they persist [14,18]. The hands of HCW can contaminate or become contaminated by ICU fomites and medical equipment after direct contact with these surfaces, and serve as vectors for the transmission of nosocomial pathogens [6,38]. The frequent isolation of CoNS from the hands of nurses (50%) in our study, and the isolation of CoNS from high-contact surfaces such as patient bed-rails, door handles, stethoscopes, medical charts and the unit telephone ( Table 1 and 2) is evidence of the important relationship between HCWs' hands and the inanimate environment in the transmission of nosocomial pathogens.…”

“…Due to their critical state, as well as other external risk factors, the rate of infection amongst ICU patients is several times higher than that of patients in other wards [4,5]. Several studies have determined environmental sources as focal points of outbreaks in critical care wards [6][7][8]. Although there is still much deliberation as to the actual role fomites (especially medical equipment) play in the transmission of HAIs in non-outbreak situations, a growing body of evidence highlights the significance of environmental disinfection in infection prevention [9][10][11].…”

Aims:A cross sectional study was conducted to determine the degree of microbial contamination of environmental surfaces and health-care workers (HCWs) in two multi-bed ICUs at a tertiaryreferral hospital in Bulawayo, Zimbabwe. Place and Duration of Study: Methodology: In total 64 surfaces were swabbed in two ICUs; inclusive of 6 hand swabs obtained from on-duty nurses. Fungal and bacterial isolates were identified using standard microbiological methods. Bacterial antibiogram profiles were determined by the Kirby-Bauer disc diffusion method. Mbanga et al.; JAMMR, 27(2): 1-15, 2018; Article no.JAMMR.42764 2 PCR was used to determine the presence of Extended Spectrum Beta Lactamase (ESBL) genes in isolated Enterobacteriaceae and the presence of the mecA gene in Staphylococcus aureus isolates. Results: Out of the 58 fomites and medical devices swabbed 50 (86.21%) were positive for bacterial contamination, with coagulase negative Staphylococci (CoNS) (20.31%) and Klebsiella species (20.31%) being the most prevalent environmental isolates. All 6 (100%) hand swabs obtained from the HCWs were positive for microbial contamination. A total of 51 (75%) of the 68 bacterial isolates were resistant to at least 3 antibiotics and 39 multi-drug resistance patterns were exhibited by the MDR isolates. Combinations of the ESBL genes blaCTX-M, blaTEM and blaSHV were detected in Escherichia coli, Klebsiella spp and Pseudomonas aeruginosa isolates. Methicillin-resistant Staphylococcus isolates (MRSA) were detected using phenotypic and molecular methods. Conclusion: ICU inanimate surfaces and medical equipment in the adult and paediatric ICUs of the referral hospital were heavily contaminated with MDR bacteria that could predispose critically ill patients to acquire nosocomial infections.

“…A infecção relacionada à assistência à saúde (IRAS)é definida como qualquer infecção adquirida após a internação do paciente, que se manifesta durante a internação ou mesmo após a alta, relacionada à internação ou a procedimentos hospitalares. Essa infecção pode ser causada pela microbiota do paciente ou por microrganismos do ambiente em que ele vivia (3) . Tendo em vista que os pacientes críticos em tratamento intensivo, na maioria das vezes se encontram em uso de cateter vesical de demora, em virtude do quadro de gravidade e da necessidade de acompanhamento preciso do débito urinário, ficam propensos ao desenvolvimento de infecções associadas às vias urinárias.…”

Objetivo: investigar as bactérias mais comuns em resultados de cultura de urina e de Aspirado Traqueal (AT) de pacientes internados em uma Unidade de Terapia Intensiva (UTI) de doenças infecciosas. Método: estudo exploratório descritivo, retrospectivo, abordagem quantitativa, realizado na UTI de um hospital público,em Fortaleza-Ceará, com 56 pacientes. Dados coletados de abril a agosto de 2015,organizados no Excel, sendo expostos em tabelas e gráficos. A pesquisa foi aprovada pelo Comitê de Ética da instituição, protocolo 037/2011. Resultados: prevaleceu o gênero masculino (68,5%), com a faixa etária variando entre 21 a 84 anos. Dentre os germes presentes nos exames avaliados, destacaram-se as bactérias A.baumannii, P.aeruginosas, E.coli, K.pneumoniae e Staphylococcus Aureus. Além da presença de fungo nas amostras, especificamente a Candida. Conclusão: Verificou-se elevada incidência de bactérias em culturas de urina e AT, com resultados positivos principalmente em amostras de aspirado traqueal e presença de fungo predominantemente nas culturas de urina. Descritores: Unidades de Terapia Intensiva. Infecção.Urina.
