| an outbreak of toxoplasmosis in an aviary collection of nicobar pigeons (caloenas nicobaria). | three out of 10 nicobar pigeons (caloenas nicobaria) in an aviary collection in south africa were found dead with no presenting clinical symptoms. histological examination of formalin-fixed tissues from all these birds revealed necrotic foci in various visceral organs (liver, spleen, heart, kidney and lungs), plus diffuse pulmonary congestion and oedema with vasculitis. numerous protozoal tachyzoites were present in all organs and there was strong positive immunohistochemical (ihc) labelling of ... | 2008 | 19244825 |
| [animal reservoirs of human virulent microsporidian species]. | the main objective of the present study was to determined the occurrence of encephalitozoon intestinalis, e. hellem, e. cuniculi, and enterocytozoon bieneusi in poland in animal faecal using the fish (fluorescent in situ hybridization) and multiplex fish techniques. additional objectives included: (1) identification of animal hosts of microsporidia that are infectious to humans amongst free-ranging, captive, livestock and domestic animals; (2) a molecular analysis of randomly selected parasite i ... | 2009 | 19579789 |
| the mysterious spotted green pigeon and its relation to the dodo and its kindred. | the closely related and extinct dodo (raphus cucullatus) and rodrigues solitaire (pezophaps solitaria), both in the subfamily raphinae, are members of a clade of morphologically very diverse pigeons. genetic analyses have revealed that the nicobar pigeon (caloenas nicobarica) is the closest living relative of these birds, thereby highlighting their ancestors' remarkable migration and morphological evolution. the spotted green pigeon (caloenas maculata) was described in 1783 and showed some simil ... | 2014 | 25027719 |
| bioinspired superhydrophobic thermochromic films with robust healability. | thermochromic films with intriguing functionalities have great potential in soft actuators, heat storage devices, and interactive interface sensors. inspired by the unique features of bird feathers (such as nicobar pigeon, anna hummingbird, mandarin duck, etc.), a superhydrophobic thermochromic film (stf) with robust healability is proposed for the first time through sandwiching an electric heater between a top thermochromic layer and a bottom poly(vinylidene fluoride-co-hexafluoropropylene) (pv ... | 2020 | 32118397 |
