“…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.

“…Our systematic literature search yielded 1694 manuscripts using the established search strategies. As per the eligibility criteria (after exclusion of duplicate texts and articles related to other topics and exclusion of text based on review criteria or owing to method quality), 182 studies were selected for analysis ( Table 1 ) [ 2 – 4 , 6 , 7 , 9 – 25 , 27 – 37 , 39 , 40 , 42 – 45 , 47 – 56 , 58 , 60 – 63 , 65 – 69 , 71 , 72 , 74 , 75 , 77 – 83 , 85 – 93 , 95 – 104 , 106 – 109 , 111 , 114 – 123 , 125 – 130 , 132 , 135 , 136 , 138 – 140 , 142 – 146 , 148 – 150 , 153 – 164 , 167 , 169 – 173 , 175 – 192 , 194 – 204 , 207 – 210 , 212 – 215 , 217 – 219 ].

The genus Entamoeba includes a variety of widely distributed species adapted to live in the digestive tracts of humans and a large variety of animals of different classes. The objective of this study was to investigate the prevalence, distribution, and molecular epidemiology of Entamoeba spp. in different classes of hosts in Brazil. Studies that analyzed hosts from several classes, including humans and domestic, wild, or captive animals, were considered. The pooled prevalence of Entamoeba spp. was calculated using the random-effects model. A total of 166 studies on humans and 16 on animals were included. The prevalence of Entamoeba spp. in the Brazilian population was 22% (95% CI: 21–24). The state with the highest prevalence was Paraiba with 72%, followed by Federal District with 53%, and Rondonia with 50%. In immunocompromized patients, the prevalence was 18%, and cancer (36%) was the most prevalent cause of immunosuppression. The prevalence of Entamoeba spp. in animal hosts was 12% (95% CI: 7–17). Captive wild animals and domestic farm animals showed the highest prevalence, with 16% and 15%, respectively. The species found more often were E. coli (86.5%), E. dispar (7.9%), and E. histolytica (3.1%). In conclusion, a high prevalence (22%) of Entamoeba spp. was found in the Brazilian population, with a prevalence of up to 50% mainly in the northern, northeastern, and central-western regions. The pathogenic species E. histolytica is distributed in most Brazilian regions, with significant prevalence percentages. Among animals, unidentified Entamoeba species were most prevalent in mammals.

Helminths are endoparasites that infect a variety of bird species. Endoparasite infections can cause severe diseases, including kill captive avian hosts and represents a problem to maintenance and conservation. The eggs and larval forms of these parasites are usually eliminated in the host feces. The main interest of this study is to report the occurrence of eggs and oocysts in feces from captive wild birds in Goiânia Zoo and free-living birds in its surroundings. The fecal samples were subjected to parasitological examination to identify the presence of helminths and to classify their eggs based on morphological characteristics. Eggs of nematode parasites (Positive/N) were identified as Ascaridia spp. in Brotogeris chiriri (2/2), Dromaius novaehollandiae (1/1) and Rhea americana (2/2); Ascarididae in Pavo cristatus nigripensis (1/1); Capillaria spp. in Ara chloropterus (1/1) and Penelope jacucaca (1/1); Capillaria plagiaticia in Anodorhynchus hyacinthinus (1/2) and Ara spp. (2/2); Capillaria venusta in Rhamphastus tucanus (1/2); and unidentified nematode eggs from Amazona amazonica (2/2). Eimeria spp. oocyst was founded in feces from A. hyacinthinus (1/2). Considering free-living birds, Diphyllobothrium spp. eggs were founded in Ardea alba (2/2) and Nycticorax nycticorax (2/3). Co-infection of Eustrongylides spp. was founded in A. alba (1/2). This is the first occurrence of: Ascaridia spp. parasitizing B. chiriri; and C. venusta parasitizing R. tucanus. In conclusion, the helminth eggs found in the abovementioned host bird species are consistent with those reported in the literature, and treatment and control protocols were based on their identification.
