“…With respect to protozoans in this host there are no available reports of their occurrence in Brazilian turkeys to the date.Recently, Brener et al (2006) studied the lesions caused by the gizzard nematode Cheilospirura hamulosa (Diesing, 1851) in turkeys from Brazilian backyard flocks, confirming its high pathogenicity, since this nematode species infects other galliform birds, mainly chickens and pheasants, provoking severe gross and microscopic lesions in these hosts. This paper deals with the prevalence and induced pathology of two helminth species, the intestinal nematode Heterakis gallinarum (Schrank, 1788), the renal digenetic trematode Paratanaisia bragai (Santos, 1934) Freitas, 1959, and the protozoan Histomonas meleagridis (Smith, 1895) in Brazilian turkeys.…”

In Brazil, reports of helminth infections occurring in turkeys are mostly restricted to general surveys of the parasites with no data on the associated pathology (Travassos 1965, Travassos et al. 1969, Vicente et al. 1995, in despite of the increasing economic importance of this bird for the ready-to-eat low fat food industry since the last decade. With respect to protozoans in this host there are no available reports of their occurrence in Brazilian turkeys to the date.Recently, Brener et al. (2006) studied the lesions caused by the gizzard nematode Cheilospirura hamulosa (Diesing, 1851) in turkeys from Brazilian backyard flocks, confirming its high pathogenicity, since this nematode species infects other galliform birds, mainly chickens and pheasants, provoking severe gross and microscopic lesions in these hosts. This paper deals with the prevalence and induced pathology of two helminth species, the intestinal nematode Heterakis gallinarum (Schrank, 1788), the renal digenetic trematode Paratanaisia bragai (Santos, 1934) Freitas, 1959, and the protozoan Histomonas meleagridis (Smith, 1895) in Brazilian turkeys. 24'44"S, 42 o 57'56"W) were investigated for helminths and protozoans. After individual clinical evaluation, taking into account the general conditions, birds were killed by jugular section (hypobolemic shock) and submitted to necropsy in accordance to the technique of Zander et al. (1997). Organs (digestive and respiratory tracts, liver, spleen, kidneys, and eyes) were opened in Petri dishes containing 0.85% NaCl solution. One of the kidneys of each animal was kept uncut for histological purposes. Helminths were fixed either in hot (nematodes) or cold (compressed/uncompressed trematodes) AFA (ethanol 70 o GL, 93 ml; formaldehyde, 5 ml; acetic acid, 2 ml). Portions of the parasitized organs were removed and immediately fixed in 10% formalin, to be further routinely processed for paraffin embedding. Five micrometers thick sections were stained with hematoxylin and eosin (HE). The recovered nematodes and trematodes were counted under a stereomicroscope. Some nematodes were clarified in acetic acid and phenol and mounted unstained in balsam; some trematodes were stained with alcoholic chloride carmine, dehydrated in an ethanol series (70-100 o ), cleared in phenol and mounted in balsam. Re- MATERIALS AND METHODS From RESULTSClinical signs were absent in turkeys parasitized with the cecal nematode H. gallinarum alone (Fig. 1); the prevalence of infection was of 70% with a range of intensity of 1-113 worms and a mean of 26 parasites; the microscopic lesions were represented by intense cecal chronic diffuse inflammatory processes with mononuclear and polymorphonuclear (heterophils) leucocytes infiltrations, that extended discretely to the submucosa, followed by edema. The mucosa presented multiple erosion foci together with parasites and cellular debris in transversal sections (Fig. 3).The prevalence of infection related to the association of H. gallinarum with the pleomorphic flagellate H. meleagridis w...

This review serves to summarize parasites found in Domesticated animals which were found in the Neo-Tropics. Indigenous domesticated Neo-tropical animals include South American camelids, (Lama gunacoa, Lama glama, Lama pacos, Vicuna vicuna), guinea pigs (Cavia porcellus), chinchillas (Chinchilla lanigera), turkeys (Meleagris gallopavo) and ducks (Cairina moschata, Anas platyrhynchos, Dendrocyga autumnalis). These animals were chosen due to their origin of existence (Neo-tropics) and over time these animals became domesticated and were distributed throughout the world. Over eighty (80) references were collected for this review and the papers spanned over eighty (80) years from 1934 to 2018. The gastrointestinal parasites reported for each animal were tabulated and their effects in the animal noted. Parasites reported in domesticated Neo-tropical animals had little to no effect on wild and free ranging animals with a few cases of illness and decreased productivity. The majority of articles viewed these animals as reservoir host which can infect humans and other domesticated livestock. It must also be noted that research done in the past did not focus on the effect these parasites had on these animals but only observed their potential as reservoirs for parasitic diseases.

“…The tapeworm is responsible for stunted growth of young chicken, emaciation of adult and decreased egg production of hen Samad et al, (1986). Recently, Brener et al,(2006) studied the lesions caused by the gizzard nematode Cheilospirura hamulosa Diesing, 1851 in turkeys from Brazilian backyard flocks, confirming its high pathogenicity, since this nematode species infects other galliform birds, mainly chickens and Pheasants, provoking severe gross and microscopic lesions in these hosts. He et al, (1990) showed that helminth infections had a significant effect on weight loss.…”

“…Data on helminths of domesticated turkeys are relatively very few and thus, the action of the parasitism affecting these hosts is little known. In Brazil, investigations related to the pathology induced by helminths in turkeys are restricted to those of the pioneer paper by Barretto and Mies-Filho (1942) and more recently to the results reported by Brener et al, (2006) describing the pathogenic action of the trematode Paratanaisia bragai, the nematodes Cheilospirura hamulosa, Heterakis gallinarum and the protozoan Histomas meleagridis infecting this avian host. But in Egypt Hussien (1991) and El-Azazy (1979) found that poultry are infected with cestodes R. echinobothridia and the peak of infection was in summer.…”

This work provides a detailed systematic morphology by optic and Scanning electron microscopy of two parasites Raillietina echinobothriida Megnin, 1880 and Spirora meleagaris n. sp. infecting domesticated turkey. The present study includes some important characters that not recorded in previous description. SEM revealed that the tegument of the first cestode exhibits, filamentous, microtriches and sensory papillae densely covered the tegument of entire body, rostellum armed with two rows of hummer-shaped hooks and provide by 16-20 rows of small, rose thorn-shaped accessory spines. In addition, the present studies have observed a number of taxonomic features in Spirora meleagaris n. sp. that differ from those mentioned in the same genus, mouth circular, bounded by a cuticular three circles plates, five pairs of cephalic papillae, an inner circle of two pairs situated on the wall of the buccal cavity, one pair of larges submedian amphids, and an outer circle of two pairs papillae. Buccal cavity supported by four chitinious cusped molar teeth anteriorly directed .Vulva near the end of the first third of the body, vulvular lips prominent. The male has unique rose like shaped pedunculated and unarranged numerous distributed sessile cervical papillae at the second third of the body that are distinguishable from other spirorid.
