Enterococcus spp in Wastewater and in Mallards (Anas platyrhynchos) Exposed to Wastewater Wetland
In this study, twelve Mallards living in an artificial wastewater wetland were exposed to treated wastewater containing 1 x 104 x 10 enterococci 100 ml for a period of 55 days. Faecal samples were collected before, during and after exposure and analysed for Enterococcus spp. The isolates were phenotyped using the PhenePlate system. 270 Enterococcus spp. of Mallard origin were analysed, together...
متن کاملLead toxicity in captive and wild Mallards (Anas platyrhynchos) in Spain.
Forty captive Mallards (Anas platyrhynchos), of both sexes, were separated into five groups and dosed with lead shot via oral intubation; one group was used as a control. Lead dosage differed in terms of shot number and size, as well as administration time. One hundred and thirty-five wild mallards were trapped between 1998 and 2001 in the Boada and Nava lagoons near the Canal de Castilla, in t...
متن کاملEmbryotoxic and teratogenic effects of petroleum hydrocarbons in mallards (Anas platyrhynchos).
Egg surface applications of microliter quantities of crude and refined oils of high aromatic content are embryotoxic to mallards (Anas platyrhynchos) and other avian species; applications of aliphatic hydrocarbons have virtually no effect. Mallard eggs at 72 h of development were exposed to a mixture of aromatic hydrocarbons or to aromatic compounds representative to those present in crude oil ...
متن کاملPrecocial hindlimbs and altricial forelimbs: partitioning ontogenetic strategies in mallards (Anas platyrhynchos).
Precocial development, in which juveniles are relatively mature at hatching or birth, is more common among vertebrates than altricial development, and is likely to be the basal condition. Altricial development characterizes many birds and mammals and is generally viewed as an alternate strategy, promoting fast growth rates, short developmental periods and relatively poor locomotor performance p...
متن کاملPectoralis muscle performance during ascending and slow level flight in mallards (Anas platyrhynchos).
In vivo measurements of pectoralis muscle length change and force production were obtained using sonomicrometry and delto-pectoral bone strain recordings during ascending and slow level flight in mallards (Anas platyrhynchos). These measurements provide a description of the force/length properties of the pectoralis under dynamic conditions during two discrete flight behaviors and allow an exami...
