-The external ant community of Hospital Municipal de Morrinhos, in Morrinhos, Goiás State, was characterized by the low rates of richness, diversity, dominance and equity of species abundance. Pheidole sp.1, a polygynic species was numerically dominant in this environment, although it coexists with potentially competitive species. This ant species prevailed within all hospital departments and its space-time distribution was a little aggregated (variance/mean ratio = 1.102, χ 2 = 29.38, P < 0.01). Escherichia, Salmonella, Aeromonas, Enterococcus, Staphylococcus and Klebsiella were the bacteria associated to this ant species in nearly all hospital annexes. The unicolonialism of Pheidole sp.1 tends to increase the contamination and dissemination process of infecto-contagious agents. The control and management of this ant species must be followed by practices that reduce the colonization process by other queens and the quantity of site nidifi cation within the hospital.KEY WORDS: Urban ant, Pheidole, polygyny, community RESUMO -A comunidade de formigas da área externa ao hospital do Hospital Municipal de Morrinhos, GO, caracterizou-se pelos baixos índices de riqueza, diversidade, dominância e eqüidade de abundância das espécies. Pheidole sp.1, uma espécie poligínica, dominou esse ambiente apesar da coexistência com espécies potencialmente competitivas. A mesma espécie de formiga predominou no interior de praticamente todas as repartições do hospital e sua distribuição espaço-temporal aproximou-se da agregada (variância/média = 1.102, χ 2 = 29.38, P < 0.01). Escherichia, Salmonella, Aeromonas, Enterococcus, Staphylococcus e Klebsiella foram os gêneros de bactérias associados a essa espécie de formiga em praticamente todas as repartições do hospital. O unicolonialismo de Pheidole sp.1 tende a potencializar o processo de contaminação e disseminação de agentes infecto-contagiosos. O manejo e controle da espécie devem ser acompanhados de técnicas que reduzam o processo de colonização por novas rainhas e a quantidade de locais de nidifi cação no interior do hospital. PALAVRAS-CHAVE: Formiga urbana, Pheidole, poliginia, comunidadeVárias espécies de formigas se beneficiam com a presença do homem, tanto na zona rural como na urbana, e algumas destacam-se como pragas devido aos problemas ocasionados direta ou indiretamente à população humana (Vinson 1986, Vander Meer et al. 1990. Espécies de formigas que vivem no interior de edifi cações em ambiente urbano são caracterizadas pelo tamanho corporal pequeno, poliginia, mobilidade das colônias e unicolinialismo (Passera 1994). As principais espécies consideradas pragas urbanas no Brasil são exóticas, destacando-se Monomorium pharaonis (L.), Monomorium fl oricola Jerdon, Paratrechina longicornis (Latreille) e Tapinoma melanocephalum (Fabricius) . Linepithema humile (Mayr), Paratrechina fulva (Mayr), Wasmannia auropunctata (Roger) e algumas espécies de Camponotus, Pheidole, Brachymyrmex e Solenopsis, nativas do Brasil, também são importantes pragas urbanas.A infecção hospi...

“…A wide variety of carbapenemase-producing Enterobacteriaceae have been reported worldwide 3,4 . Carbapenem resistance is mediated the by transfer of mobile genetic elements such as plasmids and transposons, which are easily transferred to other bacterial genera and species, i.e., Enterobacter cloacae, Citrobacter freundii, Salmonella spp., Escherichia coli, among others.…”

Introduction:In this study, we used phenotypic methods to screen carbapenem-resistant Enterobacteriaceae (CREs) and evaluated their antimicrobial sensitivity profile. Methods: One hundred and seventy-eight CREs were isolated at a university hospital in south Brazil in a one-year period. Samples were assessed using disk diffusion tests with inhibitors of β-lactamases such as phenylboronic acid (AFB), cloxacillin (CLOXA), and ethylenediaminetetraacetic acid (EDTA). Strains with differences in zone diameters ≥ 5mm for disks supplemented or not were considered producers of carbapenemases. Results: Klebsiella pneumoniae was the most prevalent CRE, which appeared in 80.3% cases (n = 143). Among clinical materials, the rectal swab was responsible for 43.4% of the isolations (n = 62), followed by urine (18.9%; n = 27). Among the CREs identified in this study, the growth of 56.7% (n = 101) isolates, which were putative producers of Klebsiella pneumoniae carbapenemase (KPC), were inhibited by AFB, whereas 7.3% (n = 13) isolates were inhibited by both AFB and CLOXA and were considered as putative producers of plasmid-mediated AmpC; approximately 3.4% (n = 6) were inhibited by EDTA, which possibly produced metallo-β-lactamase. Lastly, 32.6% (n = 58) cases showed negative results for AFB, CLOXA, and EDTA sensitivity, and represented another class of β-lactamases and/or mechanism of resistance. Conclusions: Phenotypic screening of CREs is important for clinical laboratories that monitor outbreaks of resistant microbes. Phenotypic tests that use carbapenemase inhibitors and enhancers such as AFB, CLOXA, and EDTA are necessary since they are good screening methods for the detection of carbapenemases.
