Two new species of the genus Pachyseius are described from leaf litter in Turkey. Pachyseius destitutus sp. nov. is described based on the female, and P. quadrigeminus sp. nov. is described based on the female and male. These species have some uncommon character states for the genus, such as the absence of dorsal shield seta z1, four pairs of setae on the ventri-anal shield, and a male with a h...
Trichomoniasis, caused by the protozoan Trichomonas gallinae, has as main hosts birds of Columbidae family, which have a high prevalence without manifesting disease. The continuous growth pigeon population and its cosmopolitan nature mean that today there is worldwide distribution this species, being responsible for maintenance trichomoniasis in almost entire world. transmission disease may be ...
A total of 130 faecal samples were collected from various breeds of parrots. Eighty eight samples were found positive for single or mixed infection of Heterakis gallinae and Ascardia galli. Faecal samples were examined for counting of egg/gram of faeces using McMaster egg counting technique having overall prevalence of 67.70 % with individual relative percentage as 73.86 and 26.14 respectively....
The influence of cold (4°C)used to prepare cells for metabolic investigations was examined with Trichomonas gallinae in this study. Cells washed withcold diluent in a refrigerated centrifuge were found to be less stimulated in their gas production at 37°C when exposed to glucose ormaltose than cells washed at room temperature conditions. Such cold-prepared cells had higher initial glycogen cont...
Finch trichomonosis, caused by the protozoal parasite Trichomonas gallinae, was first recognized as an emerging infectious disease of British passerines in 2005. The first year of seasonal epidemic mortality occurred in 2006 with significant declines of greenfinch Carduelis chloris and chaffinch Fringilla coelebs populations. Here, we demonstrate that large-scale mortality, principally of green...
Avian trichomonosis, caused by the flagellated protozoan Trichomonas gallinae, is a recently emerged infectious disease of British passerines. The aetiological agent, a clonal epidemic strain of the parasite, has caused unprecedented finch mortality and population-level declines in Britain and has since spread to continental Europe. To better understand the potential origin of this epidemic and...
With the purpose of identifying the causes of disease and death in backyard turkeys, 768 interviews with growers were carried out in communities of the coastal region of Oaxaca, Mexico. Later, a clinical sanitary evaluation was performed on five randomly selected turkeys of different age and sex. The laboratory tests included: necropsy for clinical diagnosis of diseases and for a histopathologi...
Emerging infectious diseases are increasingly cited as threats to wildlife, livestock and humans alike. They can threaten geographically isolated or critically endangered wildlife populations; however, relatively few studies have clearly demonstrated the extent to which emerging diseases can impact populations of common wildlife species. Here, we report the impact of an emerging protozoal disea...
Finch trichomonosis, caused by Trichomonas gallinae, emerged in the Canadian Maritime provinces in 2007 and has since caused ongoing mortality in regional purple finch (Carpodacus purpureus) and American goldfinch (Carduelis tristis) populations. Trichomonas gallinae was isolated from (1) finches and rock pigeons (Columbia livia) submitted for post-mortem or live-captured at bird feeding sites ...
