“…The disease of acute and chronic eimeriosis leads to the death of ostrich at the age of 3-4 months. The presence of helminths we have identified in ostriches is confirmed by other researchers (Ponce Gordo et al, 2002;Ederli & de Oliveira, 2015;Gallo et al, 2020). Analysis of the invasiveness of ostriches, showed that gradually changes parasstophauna pathogens helminths.…”

In ostrich farming is difficult to obtain the necessary production and economic results without protection of bird health. We determined the incidence of parasitic ostriches during the period of growing and keeping on specialized eco-zoos. Samples from small and large farms, as well as eco-parks in Kharkiv, Dnepr and Donetsk regions of Ukraine, were examined during 2016- 2020. We performed a parasitological study of 159 samples from three species of ostriches (black African ostrich, Australian common Emu (Dromaius), Rhea). Infestation of ostriches of different ages with two types of nematodes and Eimeria was established. We determoined that the population of ostriches in specialized farms and eco-zoos was infested with nematodes and protozoa with an extensiveness of invasion from 7.7% to 71.4% among adult birds, while young ostriches were infested with Emeria from 20.0% to 44.4%. The largest invasion by helminths and protozoa was observed among black African ostriches in Kharkiv region (41.4%), in Dnepr region it was 33.3%, and in Donetsk it reached 34.1%. Among the livestock of ostriches, there were both mono and mixinvasions. Most often, this was an invasion by Trichostrongylus spp. and Eimeria spp. in African black ostriches, capillaries and Eimeria in Emu. In Kharkiv region, the invasion of Capillaria by Trichostrongylus in African ostriches and Trichostrongylus in Emu were found when they were kept together. Acute and chronic eimeriosis disease can lead to the death of ostriches at the age of 3-4 months.

“…Gastrointestinal parasites are one of the most common pathogens, and can not only lead to nutritional and immune inadequacy as well as stunted growth and delayed development ( 4 , 5 , 6 , 7 , 8 23 ), but also have adverse effects on the quality of camel meat and milk ( 18 , 21 ). These consequences of parasitical infection are potential threats to food safety and the health of the majority of herders ( 1 , 9 , 12 , 13 , 27 , 28 ).…”

IntroductionGastrointestinal parasites are some of the most common pathogens which are seriously harmful to the camel’s health. The infection status of gastrointestinal parasites in camels (Camelus bactrianus) in the Tianshan Mountains pastoral area in China is still unclear. The aim of this study was to investigate the species and infection intensity of gastrointestinal tract parasites in local camels.Material and MethodsA total of 362 fresh faecal samples were collected and examined for parasite eggs using the saturated saline floating and natural sedimentation method. The parasite eggs were subjected to morphological and molecular examination and identification, and the infection rate and mean intensity of the parasites were analysed.ResultsA total of 15 gastrointestinal tract parasite species’ eggs were identified, with a detection rate of 100%. Ostertagia spp. (100%) and Trichostrongylus spp. (98.1%) were dominant. Camels were often coinfected by 5–14 species. The average number of eggs per gram of faeces was higher for Ostertagia spp. (298), Haemonchus contortus (176) and Nematodirus spp. (138). The number of species of parasites infecting young camels was significantly lower than that of adult camels, but the infection intensity in young camels was significantly higher.ConclusionGastrointestinal parasites were highly prevalent in camels from the Tianshan Mountains pastoral area in China. This finding provides important epidemiological data for the prevention and control of associated infections in camels.

“…Free-range poultry and captive wild birds are commonly housed in limited areas with high animal stocking and access to the environment and co-habit with other bird species and wild avifauna, consequently being exposed to a wide variety of generalist or host-specific gastrointestinal (GI) parasites, namely coccidia and helminths, which are still responsible for severe health and economic concerns in poultry farms and zoological collections worldwide [ 1 , 2 , 3 , 4 , 5 , 6 ].…”

“…There are also other species of Libyostrongylus , such as L. magnus and L. dentatus , the latter having only been recorded in North America thus far. Codiostomum struthionis is also commonly found in ratites, inhabiting the distal cecum and upper rectum of adult birds and occasionally being responsible for hemorrhagic processes and oedema in the cecum’s mucosa [ 2 , 12 , 13 , 14 , 15 ].…”

Mini-FLOTAC (MF) has recently been proposed for the fecal quantification of gastrointestinal (GI) parasites in birds due to its higher sensitivity and precision in comparison with the McMaster method. The current research aimed to test the use of MF in routine diagnosis of coccidia and helminth infections in several domestic and exotic bird collections in Portugal. Between July 2020 and April 2021, a total of 142 fecal samples from organic layers, peacocks and ratites were collected in four Portuguese bird collections and processed using MF and fecal cultures to identify and calculate GI parasite shedding and prevalence. The McMaster method was also used to compare the shedding levels obtained for both quantitative techniques. MF’s relative sensitivity and specificity were also assessed, using McMaster as the reference technique. The implementation of MF resulted in an average Eimeria spp. shedding higher in peacocks from bird collection 2 (502 OPG), followed by peacocks from collection 1 (107 OPG) and organic layers (24 OPG) and peacocks from collection 3 (9 OPG). Peacocks were also positive for Capillaria spp., Trichostrongylus tenuis and Strongyloides pavonis, whereas ostriches and emus were infected by L. douglassii. The MF protocol for exotic animals and the McMaster method did not differ significantly for each parasitic agent and bird species, and MF achieved relative sensitivities and specificities higher than 70% for Galliform Eimeria spp., peacock helminths and ratites’ L. douglassii infections. Higher L. douglassii EPG values were identified using the MF protocol for exotic species (2 g of feces/38 mL of sucrose solution), followed by McMaster 2/28, MF 5/45 and MF 2/18. The use of MF allowed for obtaining different intestinal parasitic populations in several bird species and locations, and MF 2/38 is globally proposed as the most suitable protocol for bird fecal samples as an alternative to the McMaster method in the diagnosis of avian intestinal parasitic infections.
