“…Unlike some human worm parasites 18 , the prevalence of H. meleagridis has increased from 6.5 to over 30% in the birds of Khorramabad (Lorestan Province, Western Iran) rural areas 19 , due to negligence on the part of veterinarians, lack of knowledge of bird owners, or absence of appropriate medications. The ban on the use of nitroimidazole active compounds (because of their side-effects on animal product consumers) and arsenic compounds in the prevention and treatment of histomoniasis 19,20 has caused a gap in the treatment of this parasite and its diseases, resulting in the recurrence of histomoniasis 21 .…”

Objective: This study aimed to investigate the in vitro effect of the extracts of five Iranian medicinal herbs on Histomonas meleagridis protozoan parasite. Methods: This study was conducted in the following three phases in Khorramabad, Iran, in 2016: 1) preparing and extracting the 5 medicinal herbs Dracocephalum kotschyi, Satureja khuzestanica, Pulicaria gnaphalodes, Olea europaea, and Echinophora platyloba DC; 2) culturing the positive cases of fecal samples in the fortified commercial medium RPMI 1640 up to 1×10 6 parasite/ml of the parasite; and 3) investigating the effect of 1.25, 2.5, and 5 mg/ml densities of each extract and metronidazole compared with the negative control on hours 2, 4, 6, 24, and 72 with Trypan blue vital stain. Results: In this study, the D. kotschyi extract which destroyed 80% of the parasites in the first two hours was the most, and the S. khuzestanica extract was the second effective extract. However, metronidazole destroyed 60% of the parasites in the first two hours and 100% in the third day and may be excreted before being effective, showing relative resistance. Conclusion:The results of the present study demonstrated that herbal medicines may be a natural source for the production of new agent to treat histomoniasis infection.

“…Authors reported that there was no difference in weight gain, mortality and clinical lesion between ducks infected and the control over at thirty-five-day period. These results showed that the ducks were resistant to clinical disease but can be used as carriers for the disease to susceptible species [81]. In Italy an outbreak of Streptocara incognita was reported in Muscovy ducks ( Carina moschata domesticus ).…”

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.

“…Apart from turkeys and chickens, other members of the galliformes, including pheasants, partridges, and farm-reared bobwhite quails can serve as hosts ( 16 – 19 ). In contrary, other avian species like ostriches and ducks show a high resistance to disease even though they may contribute to the transmission of the parasite ( 20 , 21 ).…”

Unravelling the Immunity of Poultry Against the Extracellular Protozoan Parasite Histomonas meleagridis Is a Cornerstone for Vaccine Development: A Review

et al. 2018

The protozoan parasite Histomonas meleagridis is the causative agent of histomonosis in gallinaceous birds, predominantly in turkeys and chickens. Depending on the host species the outcome of the disease can be very severe with high mortality as observed in turkeys, whereas in chickens the mortality rates are generally lower. The disease is known for more than 100 years when in vitro and in vivo investigations started to understand histomonosis and the causative pathogen. For decades histomonosis could be well-controlled by effective drugs for prevention and therapy until the withdrawal of such chemicals for reasons of consumer protection in Europe, the USA and additional countries worldwide. Consequently, research efforts also focused to find new strategies against the disease, resulting in the development of an efficacious live-attenuated vaccine. In addition to efficacy and safety several studies were performed to obtain a deeper understanding of the immune response of the host against H. meleagridis. It could be demonstrated that antibodies accumulate in different parts of the intestine of chickens following infection with H. meleagridis which was much pronounced in the ceca. Furthermore, expression profiles of various cytokines revealed that chickens mounted an effective cecal innate immune response during histomonosis compared to turkeys. Studying the cellular immune response following infection and/or vaccination of host birds showed a limitation of pronounced changes of B cells and T-cell subsets in vaccinated birds in comparison to non-protected birds. Additionally, numbers of lymphocytes including cytotoxic T cells increased in the ceca of diseased turkeys compared to infected chickens suggesting an immunopathological impact on disease pathogenesis. The identification of type 1 and type 2 T-helper (Th) cells in infected and lymphoid organs by in situ hybridization did not show a clear separation of Th cells during infection but revealed a coherence of an increase of interferon (IFN)-γ mRNA positive cells in ceca and protection. The present review not only summarizes the research performed on the immune response of host birds in the course of histomonosis but also highlights the specific features of H. meleagridis as a model organism to study immunological principles of an extracellular organism in birds.
