“…All samples were transported the same day of collection in a pre-cooled portable fridge to the laboratory for immediate processing and analysis. For parasite identification and assessment of infection frequency, we used the formol-ether technique (Larki et al 2018 ), followed by staining of slides with Lugol (Badparva and Kheirandish 2017 ). All samples were examined under a light microscope and representative photographs were taken for the subsequent identification of the parasites based on their morphological characteristics.…”

Proper health management is essential for productivity in duck farming. However, there is limited information on the effect of management conditions on rates of metabolic problems and parasitic infections in anatids. We evaluated the rates of metabolic syndromes and gastrointestinal parasite involvement in Muscovy ducks up to 12 weeks of age, under 3 management conditions: backyard, organized, and organized with probiotics. Individuals under organized management developed 2 metabolic problems: ascites, which was rare (3.5%), fatal, and affected both males and females, and angel wing syndrome, which was more frequent (10.6%), has low impact on general health, and only affected males. The treatments do not have a significant effect on the development of ascites, but only individuals in controlled conditions presented this syndrome, and due to its low prevalence, further studies with a larger sample size are required. The risk of angel wing syndrome increased significantly with probiotic supplementation. Regarding to parasitic infection, the improvement of sanitary management and the use of probiotics supplementation reduced the occurrence of coccidiosis. Similarly organized management with probiotic supplementation showed a protective effect on helminthiasis by reducing the frequency of Heterakis gallinarum and greatly reducing the helminth egg load. Coccidiosis and helminthiasis infections were not significantly correlated with the final weight of the ducks. Therefore, organized management and the use of probiotics seems to reduce the impact of parasitic infection, although it increases the risk of developing metabolic syndrome.

“…Initially, it was believed that infection with Histomonas meleagridis (H. meleagridis) primarily resulted from eating Histomonas gallinarum (H. gallinarum) eggs, either directly or through earthworms harboring these eggs (Patra et al, 2013). However, recent studies have increasingly reported H. meleagridis infections without the presence of nematodes (Badparva and Kheirandish, 2017). Recently, researchers have widely explored alternative modes of chicken infection, specifically highlighting transmission through the mouth and cloaca.…”

“…This mechanism allows pathogens to penetrate the caecum and bursa of Fabricius (Sorvari and Sorvari, 1977;Huber et al, 2006;Patra et al, 2013). This mode of infection has been identified as a risk factor for the dissemination of H. meleagridis via the cloaca (Huber et al, 2006, Badparva andKheirandish, 2017).…”

The study of macro morphological changes is important for recognizing pathological processes and diagnosing diseases, especially co-invasions. The current study aimed to reveal macro morphological changes during spontaneous co-invasion of Eimeria spp., Histomonas meleagridis, and Trichomonas gallinae in adult chickens. The methods of evisceration and parasitological studies of the carcasses of adult domestic chickens (n = 31) aged 1.5-2.3 years, and (n = 8) are the control group, died of a natural death from farms in the Kharkiv region of Ukraine revealed the peculiarities of manifestations of macro morphological changes in organs, which were characterized by manifestations of pathologies in 100% of cases in dead chickens by changes in the intestines and liver, in 48.39% in the spleen, in 16.13% in the bursa of Fabricius, in 16.13% in the peritoneum and 9.68% in skin. In particular, a mucosal-hemorrhagic inflammatory process was observed in the intestines of chickens with damage to both thin and thick parts (duodeno-jejuno-ileo-typho-cloacitis). This inflammatory process was observed in combination with necrotic-granulomatous lesions on the intestinal wall. A combined lesion of the liver was detected - hepatomegaly on the background of steatosis, multifocal necrosis, and granulomas (shiny, vitreous, with a white center) in the presence of Histomonas meleagridis and Trichomonas gallinae. A granulomatous splenitis was diagnosed in the spleen of chickens. Necrotic-granulomatous lesions leading to cyst formation were identified in the bursa of Fabricius. Additionally, granulomatous lesions originating from trichomoniasis were observed on the peritoneum and skin. These findings highlight the systemic nature of pathological-anatomical changes resulting from the co-infection of eimeriosis, histomoniasis, and trichomoniasis in domestic chickens. This systemic manifestation signifies the occurrence of multi-organ failure and holds valuable diagnostic implications.
