Poultry coccidiosis, caused by 7 Eimeria species, has a significant economic impact on the poultry industry and is managed mainly by chemotherapeutic drugs. However, alternative control measures are needed due to the emergence of drug-resistant strains. This study aimed to evaluate the anticoccidial effects of a multicomplex mineral-based diet in broilers infected with Eimeria acervulina. Broilers were fed a multicomplex mineral-based diet and infected with E. acervulina. Fecal oocyst shedding was 39.0% lower in the E. acervulina-infected broilers treated with the multicomplex mineral compared to that in untreated-infected broilers (365.7×106±45.7 versus 599.8×106±8.7, P<0.05). On day 6 post-infection, body weight gain was significantly higher in treated-infected chickens than untreated chickens (103.2±1.5% versus 94.1±1.7%, P<0.001). The lesion scores were similar between the 2 groups. Histopathological observations revealed that the width of the villi in the treated-infected chickens (286±9.5 μm) was significantly increased by 19.1% (240±10.8 μm, P<0.05) and 34.9% (212±7.3 μm, P<0.001) compared to those in the untreated-uninfected and untreated-infected groups, respectively. However, the villous height and crypt depth were similar between the untreated- and treated-infected groups. The positive effects of the dietary multicomplex mineral, including reduced fecal oocyst shedding, increased weight gain, and increased villi width, suggest its potential application in mitigating the adverse effects of Eimeria infection in both conventional and organic chicken industries.

Coccidiosis in chickens is an intestinal parasitic disease caused by protozoan parasites named Eimeria spp. In some Eimeria infections, intestinal lymphocytes are known to highly express chicken NK-lysin (cNK-lysin), an antimicrobial peptide with anticoccidial activity. Therefore, this study aims to investigate the expression of cNK-lysin in E. necatrix-infected chickens and its role in E. necatrix infection. The expression of cNK-lysin transcript was significantly increased in E. necatrix sporozoites-treated lymphocytes. In E. necatrix infection, cNK-lysin transcript was induced in intestinal lymphocytes but not in the spleen. The recombinant cNK-lysin exhibited anticoccidial activity against E. necatrix sporozoites as well as immunomodulatory activity on macrophages by inducing proinflammatory cytokines. These results indicated that E. necatrix infection induces high local expression of cNK-lysin and the secreted cNK-lysin helps protect coccidiosis.

Anticoccidial Activity of Berberine against Eimeria-Infected Chickens
Binh Thanh Nguyen, Rochelle Alipio Flores, Paula Leona Taymen Cammayo, Suk Kim, Woo Hyun Kim, Wongi Min
Korean J Parasitol 2021;59(4):403-408.

Avian coccidiosis has a major economic impact on the poultry industry, it is caused by 7 species of Eimeria, and has been primarily controlled using chemotherapeutic agents. Due to the emergence of drug-resistant strains, alternative control strategies are needed. We assessed anticoccidial effects of berberine-based diets in broiler chickens following oral infection with 5 Eimeria species (E. acervulina, E. maxima, E. tenella, E. mitis, and E. praecox). When 0.2% berberine, a concentration that does not affect weight gain, was added to the diet, the 4 groups infected with E. acervulina, E. tenella, E. mitis, or E. praecox showed significant reductions in fecal oocyst shedding (P<0.05) compared to their respective infected and untreated controls. In chickens treated 0.5% berberine instead of 0.2% and infected with E. maxima, fecal oocyst production was significantly reduced, but body weight deceased, indicating that berberine treatment was not useful for E. maxima infection. Taken together, these results illustrate the applicability of berberine for prophylactic use to control most Eimeria infections except E. maxima. Further studies on the mechanisms underlying the differences in anticoccidial susceptibility to berberine, particularly E. maxima, are remained.

Dandan Liu, Lingming Kong, Jianping Tao, Jinjun Xu
Korean J Parasitol 2018;56(6):597-602.
Published online December 31, 2018
DOI: https://doi.org/10.3347/kjp.2018.56.6.597
Histomonas meleagridis is a facultative anaerobic parasite, which can cause a common poultry disease known as histomoniasis. The species and age of the birds impacts on the susceptibility, with turkey being the most susceptible species. Chickens are less susceptible to H. meleagridis than turkeys and usually serve as reservoir hosts. Here, the diagnosis of an outbreak of histomoniasis in backyard Sanhuang chickens is described. The primary diagnosis was made based on clinical symptoms, general changes at necropsy, histopathology, and the isolation and cultivation of parasites. The pathogen was further confirmed by cloning, PCR identification, and animal inoculation tests. A strain of H. meleagri- dis, named HM-JSYZ-C, with a higher pathogenicity level in chickens was obtained. The study lays a foundation for further investigations into H. meleagridis and histomoniasis in chickens.

Toxoplasma gondii causes serious infection worldwide in humans and animals. In this study, the seroepidemiology of toxoplasmosis was investigated in wild boars (Sus scrofa) (n=377), wild rabbits (cape hare, Lapus capensis) (n=331), and wild chickens (red junglefwol, Gallus gallus) (n=571) in 4 forested and country sided area of Hubei province of China. For this, blood samples were collected and tested by indirect hemagglutination test (IHA). The seroprevalence was found to be 7.2%, 5.1%, and 12.6% in wild boars, rabbits, and chickens, respectively, with significant differences among these species. The prevalence of T. gondii infection in male and female wild boars was found to be 7.9% and 6.5% (P<0.01), in male and female rabbits was 5.6% and 4.9% (P<0.01), and in male and female chickens was 17.1% and 7.7% (P<0.01), respectively, with significant differences between 2 genders of chickens (P<0.01). The findings of this study may help in planning of the prevention measures against T. gondii infection in wild animals in this area.

Morphology and Molecular Phylogeny of Raillietina spp. (Cestoda: Cyclophyllidea: Davaineidae) from Domestic Chickens in Thailand
Preeyaporn Butboonchoo, Chalobol Wongsawad, Amnat Rojanapaibul, Jong-Yil Chai

Raillietina species are prevalent in domestic chickens (Gallus gallus domesticus) in Phayao province, northern Thailand. Their infection may cause disease and death, which affects the public health and economic situation in chicken farms. The identification of Raillietina has been based on morphology and molecular analysis. In this study, morphological observations using light (LM) and scanning electron microscopies (SEM) coupled with molecular analysis of the internal transcribed spacer 2 (ITS2) region and the nicotinamide adenine dinucleotide dehydrogenase subunit 1 (ND1) gene were employed for precise identification and phylogenetic relationship studies of Raillietina spp. Four Raillietina species, including R. echinobothrida, R. tetragona, R. cesticillus, and Raillietina sp., were recovered in domestic chickens from 4 districts in Phayao province, Thailand. LM and SEM observations revealed differences in the morphology of the scolex, position of the genital pore, number of eggs per egg capsule, and rostellar opening surface structures in all 4 species. Phylogenetic relationships were found among the phylogenetic trees obtained by the maximum likelihood and distance-based neighbor-joining methods. ITS2 and ND1 sequence data recorded from Raillietina sp. appeared to be monophyletic. The query sequences of R. echinobothrida, R. tetragona, R. cesticillus, and Raillietina sp. were separated according to the different morphological characters. This study confirmed that morphological studies combined with molecular analyses can differentiate related species within the genus Raillietina in Thailand.

Effect of Diclazuril on the Bursa of Fabricius Morphology and SIgA Expression in Chickens Infected with Eimeria tenella
Bian-hua Zhou, Li-li Liu, Jeffrey Liu, Fu-wei Yuan, Er-jie Tian, Hong-wei Wang
Korean J Parasitol 2015;53(6):675-682.

DOI: https://doi.org/10.3347/kjp.2015.53.6.675
The effects of diclazuril on the bursa of Fabricius (BF) structure and secretory IgA (SIgA) expression in chickens infected with Eimeria tenella were examined. The morphology of the BF was observed by hematoxylin and eosin staining, while ultrastructural changes were monitored by transmission electron microscopy. E. tenella infection caused the BF cell volumes to decrease, irregularly arranged, as well as, enlargement of the intercellular space. Diclazuril treatment alleviated the physical signs of damages associated with E. tenella infection. The SIgA expression in BF was analyzed by immunohistochemistry technique. The SIgA expression increased significantly by 350.4% (P<0.01) after E. tenella infection compared to the normal control group. With the treatment of diclazuril, the SIgA was relatively fewer in the cortex, and the expression level was significantly decreased by 46.7% (P<0.01) compared with the infected and untreated group. In conclusion, E. tenella infection in chickens induced obvious harmful changes in BF morphological structure and stimulated the expression of SIgA in the BF. Diclazuril treatment effectively alleviated the morphological changes. This result demonstrates a method to develop an immunological strategy in coccidiosis control.

Toxoplasma gondii is a protozoan parasite with a broad range of intermediate hosts. Chickens as important food-producing animals can also serve as intermediate hosts. To date, experimental studies on the pathogenicity of T. gondii in broiler chickens were rarely reported. The
objective
of the present study was to compare the pathogenicity of 5 different T. gondii strains (RH, CN, JS, CAT2, and CAT3) from various host species origin in 10-day-old chickens. Each group of chickens was infected intraperitoneally with 5×108, 1×108, 1×107, and 1×106 tachyzoites of the 5 strains, respectively. The negative control group was mockly inoculated with PBS alone. After infection, clinical symptoms and rectal temperatures of all the chickens were checked daily. Dead chickens during acute phage of the infection were checked for T. gondii tachyzoites by microscope, while living cases were checked for T. gondii infection at day 53 post-inoculation (PI) by PCR method. Histopathological sections were used to observe the pathological changes in the dead chickens and the living animals at day 53 PI. No significant differences were found in survival periods, histopathological findings, and clinical symptoms among the chickens infected with the RH, CN, CAT2, and CAT3 strains. Histopathological findings and clinical symptoms of the JS (chicken origin) group were similar to the others. However, average survival times of infected chickens of the JS group inoculated with 5×108 and 1×108 tachyzoites were 30.0 and 188.4 hr, respectively, significantly shorter than those of the other 4 mammalian isolates. Chickens exposed to 108 of T. gondii tachyzoites and higher showed acute signs of toxoplasmosis, and the lesions were relatively more severe than those exposed to lower doses. The results indicated that the pathogenicity of JS strain was comparatively stronger to the chicken, and the pathogenicity was dose-dependent.

Effects of Simple and Disposable Chicken Cages for Experimental Eimeria Infections
Jeongmi Yoo, Sung H. Kang, Jipseol Jeong, Woo H. Kim, Suk Kim, Hyun S. Lillehoj, Wongi Min
Korean J Parasitol 2011;49(3):299-302.
Published online September 30, 2011
DOI: https://doi.org/10.3347/kjp.2011.49.3.299

During experimental Eimeria infections in chickens, facilities are often contaminated by fecal oocysts known to be highly resistant to both chemical and enzymatic treatments. Thus, studies using experimental Eimeria infections have been limited due to the difficulty of complete elimination of residual oocysts from both cages and facilities. To overcome this limitation, simple, inexpensive, and disposable cages were constructed from cardboard boxes and tested during experimental Eimeria maxima infections. The cages were used in animal rooms with only a 1.7% evidence of coccidia contamination between adjacent cages. No significant differences in fecal oocyst output and body weight gain were noted between animals housed in disposable cages and animals housed in wire control cages. This cage design is a useful means for preventing oocyst contamination during experimental conditions, suggesting that this disposable cage design could be used for other avian infectious disease studies.

Viability of preserved Cryptosporidium baileyi oocysts
Chan-Gu Surl, Se-Min Kim, Hyeon-Cheol Kim
Korean J Parasitol 2003;41(4):197-201.
Published online December 20, 2003
DOI: https://doi.org/10.3347/kjp.2003.41.4.197

The present study was undertaken to determine the viability and infectivity of oocysts of Cryptosporidium baileyi that had been stored from 1 to 40 months at 4℃ preserved in 2.5% potassium dichromate solution. Oocysts of C. baileyi were purified from the feces of experimentally infected chickens using discontinuous sucrose gradients. Subsequently, the purified oocysts were suspended in 2.5% potassium dichromate solution at a concentration of 1 × 107 organism/ml, and their viabilities were assessed by nucleic acid staining, histologic examination, and infectivity to 2-day-old chickens. All chickens inoculated with oocysts that had been stored for 1-18 months developed patent infections, while chickens infected with older oocysts remained uninfected. Between 5.8% and 82.2% of the oocysts, stored at 4℃ in 2.5% potassium dichromate solution, were found to be viable, as determined by nucleic acid staining. Parasite colonization in the bursa of Fabricius was detected in the microvillus border of bursal epithelium. The finding that C. baileyi oocysts remain infective to chickens for at least 18 months offers important time-saving advantages to investigators who frequently require large numbers of oocysts.

Longevity of Toxocara cati Larvae and Pathology in Tissues of Experimentally Infected Chickens
Oryan, Ahmad , Sadjjadi, Seyyed Mahmoud , Azizi, Shahrzad
Korean J Parasitol 2010;48(1):79-80.
DOI: https://doi.org/10.3347/kjp.2010.48.1.79
This study was conducted to determine the distribution patterns and duration of stay of Toxocara cati larvae in organs of chickens and to investigate chronic phase and potential zoonotic risk of toxocariasis in chickens. Chickens were orally infected with 1,000 embryonated T. cati eggs and necropsied 240 days post-infection. Organs of the chickens were examined at gross and microscopic levels; tissues were digested to recover larvae. Peribronchiolitis with infiltration of lymphocytes, and hyperplasia of bronchiolar associated lymphatic tissues (BALT) and goblet cells, were evident in the lungs of infected chickens. There were mild hemorrhages and infiltration of lymphocytes and a few eosinophils in the meninges. Larvae were recovered from 30% of the exposed chickens. Larvae recovery indicated that T. cati larvae stay alive for at least 240 days in the chicken brain. Therefore, chickens may potentially act as a paratenic host in nature and transfer T. cati larvae to other hosts.
