Lysis of Erythrocytes by Trichomonas gallinae

Avian Diseases, 1996
The hemolytic activity of five live isolates of Trichomonas gallinae was investigated. The isolates were subsequently tested against the erythrocytes of seven adult animal species. Each of the five isolates tested lysed all human blood groups, as well as rabbit, rat, chicken, horse, bovine, and sheep erythrocytes.

An analysis of oxidative metabolism in trichomonas gallinae

Comparative Biochemistry and Physiology Part B: Comparative Biochemistry, 1976
Abstract 1. 1. Key enzymes of oxidative metabolism were assayed in cell-free extracts of the anaerobic protozoan, Trichomonas gallinae . 2. 2. The sole enzyme of the tricarboxylic acid (TCA) cycle detected was malic dehydrogenase. 3. 3. T.

Persistence ofTrichomonas gallinaein Birdseed

Avian Diseases, 2017
Trichomonas gallinae has emerged worldwide as a cause of mortality in songbirds (passerines). The congregation of numerous birds, including the reservoir hosts, pigeons and doves (columbids), at backyard feeding and watering sources has been suggested as a potential driver for the outbreaks. Evidence supporting a role for water in transmission has been

Trichomonas gallinae INFECTIONS IN THE RINGDOVE (Streptopelia risoria)

Journal of Wildlife Diseases, 1982
Twenty Trichomonas-free ringdoves (Streptopelia risoria) were intubated with Trichomonas gallinae derived from pigeons (Columba livia). By 15 days post-intubation (DPI) five doves had T. gallinae-type lesions (Cankers) in the pregastric portion of the digestive system, and six doves had T. gallinae present without lesions. Sixteen Trichomonas-free ring

Use of FTA technology for detection of Trichomonas gallinae

Veterinary Parasitology, 2015
Trichomonas gallinae is the causative agent for avian trichomonosis, which can have important population implications for domestic turkeys, columbids, raptors, and various passeriformes. Continued population surveillance and genotype distribution is needed to elucidate transmission dynamics and prevalence of T.

Studies on Trichomonas gallinae Infections in Pigeon Squabs

The Journal of Parasitology, 1946
A survey of the literature shows that Trichomonas gallinae, pathogenic for birds, has been experimentally placed in a variety of avian hosts (see review paper by Levine, Boley, and Hester, 1941). To mention only a few, natural occurrences of trichomoniasis have been reported in domestic varieties of turkeys (Volkmar, 1930; Hawn, 1937), chickens (Levine

Scanning electron microscopy study of Trichomonas gallinae

Veterinary Parasitology, 2003
A scanning electron microscopy (SEM) study of Trichomonas gallinae (Rivolta, 1878), provided more information about the morphology of this flagellated protozoan. SEM showed the morphological features of the trophozoites; the emergence of the anterior flagella, the structure of the undulating membrane, the position and shape of the pelta, axostyle and ...

THE SENSITIVITY OF TRICHOMONAS VAGINALIS AND TRICHOMONAS GALLINAE TO ULTRAVIOLET RADIATION

Photochemistry and Photobiology, 1981
Abstract The formation of colonies in solid medium was used as a criterion of viability to determine the effect of ultraviolet radiation on Trichomonas vaginalis. Both viability (colony) counts and total cell (hemocytometer) counts were used to estimate physiological ages of cell populations to be irradiated. Washed‐cell suspensions in 0.6% saline were

Purification and properties of malic dehydrogenase from Trichomonas gallinae

Experimental Parasitology, 1974
Abstract The malic dehydrogenase (MDH 2 , l -malate: NAD oxidoreductase, E.C. 1,1.1.37) of Trichomonas gallinae was purified 215-fold and characterized. The molecular weight was found to be 72,000 and the enzyme protein contained essential cations and sulfhydryl groups.

Variations in Virulence of Strains of Trichomonas gallinae in Pigeons

The Journal of Parasitology, 1948
It has long been known that not all pigeons which harbor Trichomonas gallinae die of the infection or even show gross lesions indicative of the parasite's presence. Likewise, the squabs of some birds in a loft may nearly always die of trichomoniasis in a few days or weeks after hatching; whereas other parents in nearby nests, though infected, will ...
