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, chi2 = 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 nidification within the hospital.
位于戈亚斯州莫林霍斯的市立莫林霍斯医院的外部蚂蚁群落具有物种丰富度、多样性、优势度和多度均匀度较低的特征。多雌蚁物种费氏小家蚁1号（Pheidole sp.1）在这种环境中数量上占主导地位，尽管它与潜在的竞争物种共存。这种蚂蚁物种在医院所有科室中都占优势，其时空分布略显聚集（方差/均值比 = 1.102，卡方 = 29.38，P < 0.01）。在几乎所有医院附属建筑中，大肠杆菌、沙门氏菌、气单胞菌、肠球菌、葡萄球菌和克雷伯氏菌都是与这种蚂蚁物种相关的细菌。费氏小家蚁1号的单巢性倾向于增加传染性病原体的污染和传播过程。对这种蚂蚁物种的控制和管理必须辅之以减少其他蚁群在医院内的定殖过程以及巢穴数量的措施。
