| [mallophaga of pigeons in cracow]. | infestation of columba livia domestica gmelin with mallophaga has been investigated in both, breeding and feral pigeons. all pigeons came from the area of cracow. five species of mallophaga have been distinguished: columbicola columbae columbae (l.), campanulotes bidentatus compar (burm.), coloceras damicornis fahrenholzi eichler, hohorstiella gigantea lata (piag.), neocolpocephalum (neocolpocephalum) turbinatum (denny). it appeared that the first two of the above-mentioned species showed the hi ... | 1996 | 8967083 |
| [observations on the vitality of lice from dead pigeons]. | experiments were carried out in july, september, october 1993 and january 1994 on 48 dead pigeons kept in cold storage (refrigerating machine) and at a window. the behaviour of mallophaga was observed. the insects left the feather after the cooling of the bird body, usually after 24 hours. the process lasted 3 days in cold storage conditions, while in outdoor (open-air) environment the mallophaga were still alive for another 14 days. the vitality of mallophaga is bigger in open-air, in moderatel ... | 1996 | 9012136 |
| health status of free-living pigeons (columba livia domestica) in the city of ljubljana. | in the year 2000 an epidemiological research was undertaken on the health status of free-living pigeons in the city of ljubljana, slovenia. a total of 139 pigeons were captured and examined for the most common bacterial, viral, and parasitic diseases. serum samples, oropharyngeal and cloacal swabs as well as samples of droppings and feathers were taken from the captured birds. antibodies to paramyxovirus type 1 were found in 84.2% of the sera examined, and 23.7% of birds were serologically posit ... | 2004 | 15168753 |
| extraordinary number of gene rearrangements in the mitochondrial genomes of lice (phthiraptera: insecta). | the arrangement of genes in the mitochondrial (mt) genomes of most insects is the same, or near-identical, to that inferred to be ancestral for insects. we sequenced the entire mt genome of the small pigeon louse, campanulotes bidentatus compar, and part of the mt genomes of nine other species of lice. these species were from six families and the three main suborders of the order phthiraptera. there was no variation in gene arrangement among species within a family but there was much variation i ... | 2006 | 16469069 |
| [analyses of the population structures of mallophaga infesting urban pigeons]. | a total of 70 pigeons from cracow area was examined and the representation of bird lice (mallophaga) infesting them estimated. mostly the populations of two dominant species: columbicola columbae columbae (l.) and campanulotes bidentatus compar (burm.) were assessed. 47% of birds inspected had less than 100 specimens of mallophaga, although the highest infested one had 900 specimens. sex and age of pigeons did not influence the number of bird lice present, and only weak health condition of indiv ... | 2000 | 16886355 |
| host defence mediates interspecific competition in ectoparasites. | 1. interspecific competition influences which, how many and where species coexist in biological communities. interactions between species in different trophic levels can mediate interspecific competition; e.g. predators are known to reduce competition between prey species by suppressing their population sizes. a parallel phenomenon may take place in host-parasite systems, with host defence mediating competition between parasite species. 2. we experimentally investigated the impact of host defenc ... | 2008 | 18194262 |
| a hitchhiker's guide to parasite transmission: the phoretic behaviour of feather lice. | transmission to new hosts is a fundamental challenge for parasites. some species meet this challenge by hitchhiking on other, more mobile parasite species, a behaviour known as phoresis. for example, feather-feeding lice that parasitise birds disperse to new hosts by hitchhiking on parasitic louse flies, which fly between individual birds. oddly, however, some species of feather lice do not engage in phoresis. for example, although rock pigeon (columba livia) "wing" lice (columbicola columbae) f ... | 2009 | 19038259 |
| [effects of the environment on health of feral pigeons (columba livia)]. | we examined 80 feral pigeons and their fecal samples from two feral pigeon lofts of the "pigeon action of basel" (switzerland) for different pathogens. the tested material harbored four pathogenic agents transmissible to humans (chlamydia spp., salmonella spec., campylobacter jejuni, cryptococcus neoformans) in addition several pathogens were found which are no zoonotic agents but potentially pathogenic for the pigeons themselves, such as trichomonas gallinae, coccidia, helminths, ectoparasites ... | 2015 | 25876285 |
| campanulotes compar (burmeister, 1838) (phthiraptera: ischnocera) in chickens (gallus gallus domesticus) from rio grande do norte state, brazil. the reemergence of an ectoparasite? | the importance of ectoparasites in the transmission of pathogens, as well as the variability of species from one region to another, motivated this notification of the ectoparasite lice campanulotes compar in range chickens (gallus gallus domesticus l.) reared in an extensive system in the city of apodi, rio grande do norte state, in the northeast region of brazil. the examined birds were infested with ten males and six females of c. compar. thus, c. compar is recorded as parasitizing chickens in ... | 2013 | 23347760 |
