An outbreak of Acinetobacter baumannii septicemia in a neonatal intensive care unit of a university hospital in Brazil BJID
Brito,Denise von Dolinger de; Oliveira,Elias José; Abdallah,Vânia O. Steffen; Darini,Ana Lúcia da Costa; Gontijo Filho,Paulo P..
We studied an outbreak of two multi-drug resistant clones of Acinetobacter baumannii in the Neonatal Intensive Care Unit of the Uberlândia Federal University Hospital in Minas Gerais state, Brazil, and we analyzed the contribution of cross-transmission in the rise in infection rates. Eleven neonates who developed multi-drug resistant A. baumannii nosocomial infection were matched to 22 neonates who were admitted to the same unit and did not develop an infection during the outbreak period, in order to identify risk factors for infection. Three out of the 11 neonates died. Epidemiological investigation included molecular typing, using pulsed field gel electrophoresis. Prior to the outbreak, from December 2001 to March 2002, no case of infection by this...

ANTHROPOGENIC IMPACTS ON YELLOW-SPOTTED RIVER TURTLE Podocnemis unifilis (REPTILIA: PODOCNEMIDIDAE) FROM THE BRAZILIAN AMAZON Acta biol.Colomb.
Santos ARRAES,Débora Regina; Albuquerque CUNHA,Helenilza Ferreira; TAVARES-DIAS,Marcos.
The purpuse of this study was to investigated the influence of anthropogenic impacts on Podocnemis unifilis nesting on a stretch from Falsino river, with two forest reserves, and one urban area on the Araguari river, state of Amapá, eastern Amazon (Brazil). A total of 180 nests were found, being 89.4 % in the forest reserves and only 10.6 % in urban areas. On Falsino river, we observed a spawning pattern, because the number of nests was correlated to the length and width of the nesting locations. On Araguari river, the P. unifilis nests were generally found in areas with surrounding vegetation up to 5 meters in height, minimum distance of 120 meters from residences and immediately or after places of higher exploration of pebbles. Females from Falsino river...

Infection and colonization by Staphylococcus aureus in a high risk nursery of a Brazilian teaching hospital BJID
Silva,Helisângela de Almeida; Abdallah,Vânia O. Steffen; Carneiro,Cláudia Lúcia; Gontijo Filho,Paulo P..
Neonates are susceptible to nosocomial infections due to immunological immaturity, prolonged hospital stay and the use of invasive procedures. We evaluated the incidence of infections and the prevalence of colonization by MRSA (Methicillin-resistant Staphylococcus aureus) and MSSA (Methilin-susceptible Staphylococcus aureus), as well as colonization risk factors. Staphylococcal infections were observed by analyzing medical records in the HICS (Hospital Infection Control Service) and the HRN (High Risk Nursery). Additionally, four inquiries concerning colonization prevalence were made for S. aureus, from January/2000 to December/2002. Clinical specimens from the nostrils, mouth and anus were cultivated in mannitol-salt agar plates and identification was...

Late onset sepsis in newborn babies: epidemiology and effect of a bundle to prevent central line associated bloodstream infections in the neonatal intensive care unit BJID
Resende,Daiane Silva; Peppe,Anna Laura Gil; Reis,Heloisio dos; Abdallah,Vânia Olivetti Steffen; Ribas,Rosineide Marques; Gontijo Filho,Paulo Pinto.
Aim:We assessed late onset sepsis (LOS) rates of neonates in a neonatal intensive care unit (NICU) before and after implementing an evidence-based bundle to prevent these infections in a country with poor resources.Methods:We evaluate trends of LOS between October 2010 and August 2012 in a large tertiary hospital in Brazil. We designed a protocol based of CDC guidelines for insertion of maintenance of central venous catheter targeted to reduction of bloodstream infections. During this period two major events occurred: a great increase of LOS rates in January months and relocation of the unit to a provisory place. Additionally we evaluated the risk factors and etiology of these infections.Results:A total of 112 (20.3%) cases defined as LOS were found. The...

Brito,Denise Von Dolinger de; Oliveira,Elias Jose; Darini,Ana Lúcia da Costa; Abdallah,Vânia Olivetti Steffen; Gontijo Filho,Paulo P..
Staphylococcus aureus and coagulase-negative staphylococci (CoNS) are among the most important nosocomial pathogens in patients from neonatal intensive care units, mainly in bloodstream infections. The main objective of this study is to determine the occurrence of nosocomial infections by these microorganisms using two surveillance systems (Laboratorial Surveillance and National Nosocomial Infection Surveillance System) and to determine the most important risk factors during a two-year period (2001-2002). Two outbreaks by both methicillin susceptible S. aureus (MSSA) (1.5%) and methicillin resistant CoNS (MRCoNS) (1.0%) were observed, from January to February/02 and August to September/02. Endemic incidence rates of 3.77% and 5.16% of S. aureus and CoNS,...

Brito,Denise V.D. de; von Dolinger,Elias J.O.; Abdallah,Vânia O.S.; Darini,Ana Lúcia C.; Gontijo Filho,Paulo P..
Staphylococcus aureus and coagulase-negative staphylococci are the main cause of sepsis in Neonatal Intensive Care Unit (NICU). Central venous catheters (CVCs) are an important part of critical neonates' treatment and are associated with sepsis. The aim of this study was to investigate two outbreaks caused by Staphylococcus aureus and Staphylococcus epidermidis associated with CVC inserted by phlebotomy in critical neonates. The surveillance was performed from January 2001 to December 2005 at the Brazilian NICU. The genotypic analysis of oxacillin susceptible S. aureus (OSSA) and oxacillin resistant S. epidermidis (ORSE) was performed based on pulsed-field gel electrophoresis (PFGE). Staphylococcus was the most frequent pathogen (65.8%) with highest...

Use of a nursery area by cownose rays (Rhinopteridae) in southeastern Brazil Neotropical Ichthyology
Rangel,Bianca S.; Rodrigues,Alexandre; Moreira,Renata G..
ABSTRACT Using non-lethal methods for data collection of individuals and participatory monitoring by fishermen, we provide the first empirical evidence of the use of a nursery area by neonate and young-of-the-year cownose rays Rhinoptera bonasus and R. brasiliensis in southeastern Brazil. Two methods were used to collect data: (1) information provided by fishermen (reports, pictures, and videos) and (2) field sampling by researchers. A total of 746 cownose rays were captured; 113 have been identified as R. bonasus, 15 as R. brasiliensis, and 618 were reported by fishermen and could not be identified to the species. Records of newborns were made only in late spring and summer in 2015, 2016, and 2017, which suggests an annual reproductive cycle, with birth...
