The present study was developed to evaluate the in vitro effects of free essential oils (OEs) and nanostructured Ocimum basilicum and Eucalyptus globulus against trophozoites of T. gallinae. T. gallinae trophozoites were recovered by the swab method from naturally infected urban pigeons, followed by cultivation in TYM medium (trypticase-yeast-maltose extract).

PhD thesis, University of Leeds. Disease is usually ignored as a potential driver of species decline. This is concerning since disease could have a greater impact on a species as it becomes vulnerable to other extinction risks. This thesis investigated Trichomonas gallinae infection in the UK’s fastest declining farmland bird, the European Turtle Dove Streptopelia turtur. It employed molecular techniques to acquire data on parasite prevalence and identify strains, and trialled the application of Next Generation Sequencing technology to disease surveillance. AVIAN PATHOLOGY 08/01/09 Prevalence and genotyping of Trichomonas gallinae in pigeons and birds of prey in eastern Spain. Abstract : Avian trichomonosis is a world-wide parasitic disease caused by the protozoan Trichomonas gallinae.
Although several degrees of pathogenicity have been described on the basis of the clinical signs in birds, there are few reports concerning the genetic charaterization of the parasite and its relationship with pathogenicity. The parasite usually appears apathogenic but is occasionally responsible for outbreaks of the disease in avian populations, particularly affecting nestlings of ornithophagous raptors. PLOS 09/08/18 Prevalence and genotyping of Trichomonas infections in wild birds in central Germany. Abstract Avian trichomonosis is a widespread disease in columbids and other birds, caused by ingestion of the unicellular flagellate Trichomonas gallinae which proliferate primarily in the upper respiratory tracts.
Studies using genetic analyses have determined some highly pathogenic lineages in birds, but the prevalence and distribution of potentially pathogenic and non-pathogenic T. gallinae lineages in wild birds is still not well known. We examined 440 oral swab samples of 35 bird species collected between 2015 and 2017 in Hesse, central Germany, for Trichomonas spp. infection and for determining the genetic lineages.
Of these birds, 152 individuals were caught in the wild and 288 individuals were admitted from the wild to a veterinary clinic. J Wildl Dis. 2018 Oct;54(4):755-764.

Parasites & Vectors 18/05/17 High prevalence of Trichomonas gallinae in wild columbids across western and southern Europe.
Prevalence of Trichomonas in columbids Stock doves, wood pigeons, collared doves and turtle doves in our study throughout a range of European sites showed a high prevalence of infection by Trichomonas sp.
These results are in agreement with previous findings in the UK . Although we only had a small sample size of collared doves, the prevalence seems high (67%). Additionally, if we separate the results by countries, Spanish collared doves suggest a much lower prevalence by Trichomonas sp. (33%) than in the UK (86%, see ) and lie closer to the prevalence shown in Iraq (10%, see ), but the samples from Malta showed a prevalence closer to the results shown in the UK (Fig. 1). Both compared studies used swab samples [12, 46] as we did in our survey, thus the differences cannot be linked to the different sample material. In our study, stock doves had a much higher prevalence than previously suggested (22–40% [12, 45]).

JOURNAL OF WILDLIFE DISEASES - 2016 - ECOLOGIC DRIVERS AND POPULATION IMPACTS OF AVIAN TRICHOMONOSIS MORTALITY EVENTS IN BAND-TAILED PIGEONS (PATAGIOENAS FASCIATA° IN CALIFORNIA, USA. : Avian trichomonosis, a disease typically caused by the protozoan parasite Trichomonas gallinae , is a well recognized cause of death in many avian species.
In California, US, trichomonosis has caused periodic epidemics in Pacific Coast Band-tailed Pigeons ( Patagioenas fasciata monilis). We summarize reported mortality events and investigate ecologic drivers and population impacts associated with epidemic mortality due to trichomonosis in Band-tailed Pigeons. Between 1945 and 2014, 59 mortality events involving Band-tailed Pigeons were reported in California with the number of reported events increasing over time. Estimated mortality for these events was variable, ranging between 10 and 10,000 pigeons. FOLIA PARASITOLOGICA - 2015 - Trichomonosis in Eurasian sparrowhawks in the Czech Republic.

Isolate concentrations of 10 or 100 trichomonads/40 μl, from two T. gallinae isolates were inoculated onto a FTA Elute cards and analyzed by conventional polymerase chain reaction (PCR) using trichomonad-specific primers at 48 h, 2 weeks, and 3 weeks post inoculation.

Detection of the European epidemic strain of Trichomonas gallinae in finches, but not other non-columbiformes, in the absence of macroscopic disease. Finch trichomonosis is an emerging infectious disease affecting European passerines caused by a clonal strain of Trichomonas gallinae. Migrating chaffinches (Fringilla coelebs) were proposed as the likely vector of parasite spread from Great Britain to Fennoscandia.
To test for such parasite carriage, we screened samples of oesophagus/crop from 275 Apodiform, Passeriform and Piciform birds (40 species) which had no macroscopic evidence of trichomonosis (i.e. necrotic ingluvitis). These birds were found dead following the emergence of trichomonosis in Great Britain, 2009-2012, and were examined post-mortem.
Polymerase chain reactions were used to detect (ITS1/5·8S rRNA/ITS2 region and single subunit rRNA gene) and to subtype (Fe-hydrogenase gene) T. gallinae. Trichomonas gallinae was detected in six finches [three chaffinches, two greenfinches (Chloris chloris) and a bullfinch (Pyrrhula pyrrhula)]. J Parasitol. 2014 Jun;100(3):360-3.

PLOS 18/08/10 Emerging Infectious Disease Leads to Rapid Population Declines of Common British Birds. Abstract 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 disease on British populations of greenfinch Carduelis chloris and chaffinch Fringilla coelebs, two of the most common birds in Britain.

POULTRY SITE 14/07/14 New Parasite Found to Cause Deaths of Wild Pigeons. Poultry News New Parasite Found to Cause Deaths of Wild Pigeons 14 July 2014 US - University of California Davis researchers have identified the cause of death in wild band-tailed pigeons connected to newly discovered parasite. Researchers at UC Davis and the California Department of Fish and Wildlife have identified trichomonosis as a key factor in winter die-offs and population decline of bandtailed pidgeons, a native migratory game bird. (Dianne Ricky/courtesy photo) A new pathogen has been discovered by scientists investigating major die-offs of pigeons native to North America, according to studies led by the University of California, Davis, and the California Department of Fish and Wildlife.
AUDUBON 11/02/15 What’s Killing California’s Native Pigeons? A vicious parasite has felled thousands of birds. Here’s how you can help prevent its spread.(Trichomonas gallinae) Thousands of Band-tailed Pigeons have dropped dead along the Golden State’s coast. Since mid-December, caracasses of the migrartory species have been found in forests and mountains from San Diego to San Francisco (the birds winter in California). Here’s our guide to what’s going on. Why is this happening? The West Coast birds are being killed by a disease called avian trichomoniasis, caused by a single-celled protozoan called Trichomonas gallinae, autopsies at the California Department of Fish and Wildlife (CDFW) have shown.
(A similar but distinct parasite discovered in July 2014, called Trichomonas stableri, may be responsible for some of the bird deaths.)
