Abstract
Cryptocaryon irritans, a parasitic ciliate, pose a major threat to marine teleost fish aquaculture. So far, no effective and safe control method is available. In this study, the protective efficacy of a recombinant truncated surface antigen of C. irritans (rCiSA32.6t) for large yellow croaker (Larimichthys crocea) against the parasite challenge with a sub-lethal dose of the infective theronts was evaluated by comparing the relative percent survivals (RPS), the specific antibody titers in sera, and the expression levels of the immune-related genes among the negative or adjuvant control fish, fish intraperitoneally immunized with rCiSA32.6t. The results showed that a RPS of 50.1% in rCiSA32.6t-immunized fish was achieved in comparison to negative control fish against C. irritans. A significant increase was noted in the antigen-specific immunoglobulin M (IgM) and immunoglobulin T (IgT) antibody levels in the sera of the rCiSA32.6t-vaccinated fish. Compared to the negative control fish, quantitative real-time PCR analysis indicated that the interleukin-1beta, IgT, and IgM heavy chain mRNA level in the fish head kidney, spleen, gill, and skin tissue were upregulated post-rCiSA32.6t immunization. This study indicates that the rCiSA32.6t can provide a high level of immune protection against C. irritans infection in grouper and is therefore pursued as a candidate C. irritans vaccine.

Toxoplasma gondii Recombinant Antigens in the Serodiagnosis of Toxoplasmosis in Domestic and Farm Animals. Animals (Basel) 2020; 10:ani10081245. [PMID: 32707821 PMCID: PMC7459674 DOI: 10.3390/ani10081245] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/30/2020] [Revised: 07/15/2020] [Accepted: 07/20/2020] [Indexed: 12/22/2022] Open
Abstract
Simple Summary The very common parasite infections in animals are caused by members of Apicomplexa, including Toxoplasma gondii, Neospora sp., and Sarcocystis sp. These parasites pose serious veterinary problems. For example, the development of unambiguous diagnostic algorithms and determining the correct diagnosis are hindered by the similar antigenic structure of these parasites, as well as the multitude of similar disease symptoms presented in an infected animal. The intracellular parasite, T. gondii, infects a wide range of warm-blooded animals, including humans. This parasite is widespread among different animal populations, contributes to the loss of reproductive and malformations in young individuals, and can become a serious economic concern for farmers. Additionally, the consumption of undercooked or raw meat and the consumption of improperly processed milk product derived from farm animals are the main parasite transmission routes in humans. This work reviews potential improvements to diagnostic techniques that use recombinant antigens for serodiagnosis of toxoplasmosis in various species of animals. Abstract Toxoplasmosis is caused by an intracellular protozoan, Toxoplasma gondii, and is a parasitic disease that occurs in all warm-blooded animals, including humans. Toxoplasmosis is one of the most common parasitic diseases of animals and results in reproductive losses. Toxoplasmosis in humans is usually caused by eating raw or undercooked meat or consuming dairy products containing the parasite. Diagnosis of toxoplasmosis is currently based on serological assays using native antigens to detect specific anti-T. gondii antibodies. Due to the high price, the available commercial agglutination assays are not suited to test a large number of animal serum samples. The recent development of proteomics elucidated the antigenic structure of T. gondii and enabled the development of various recombinant antigens that can be used in new, cheaper, and more effective diagnostic tools. Continuous development of scientific disciplines, such as molecular biology and genetic engineering, allows for the production of new recombinant antigens and provides the basis for new diagnostic tests for the detection of anti-T. gondii antibodies in animal serum samples.

Prevalence of Toxoplasma gondii in Chicken samples from delta of Egypt using ELISA, histopathology and immunohistochemistry. J Parasit Dis 2014; 40:485-90.

Abstract
Estimates of the zoonotic diseases are helpful for monitoring and improving public health. Laboratory-based surveillance provides crucial information for assessing zoonotic disease trends and developments. Toxoplasmosis is considered as a zoonotic disease and has both medical and veterinary importance since it leads to abortion in humans and several animal species. In view of the worldwide importance of T. gondii, this study aimed to estimate the prevalence of T. gondii in chickens from the Delta of Egypt. A total of 304 blood and brain samples were collected from Egyptian chickens from Gharbiya, Qalyoubiya, Minufiya, Beheira, Kafr EL-Shaykh and Dakahlia Provinces. In order to determine the serological and histopathological prevalence of T. gondii, the samples were examined by ELISA, histopathology and immunohistochemistry (IHC). The prevalence of T. gondii was 11.18, 6.91, 6.91 % by ELISA, histopathology and IHC, respectively. Statistically significant differences in the prevalence of T. gondii were observed on the basis of season, sex and habitat. These data provide valuable information regarding the epidemiology of T. gondii infections in Egyptian chickens, which can be employed in developing efficient strategies for disease management and control.

Abstract
Recombinant antigenic proteins of Toxoplasma gondii are alternative source of antigens which are easily obtainable for serodiagnosis of toxoplasmosis. In this study, highly antigenic secretory organellar proteins, dense granular GRA2 and GRA3, rhoptrial ROP2, and micronemal MIC2, were analyzed by bioinformatics approach to express as water-soluble forms of antigenic domains. The transmembrane region and disorder tendency of 4 secretory proteins were predicted to clone the genes into pGEX-4T-1 vector. Recombinant plasmids were transformed into BL21 (DE3) pLysS E. coli, and GST fusion proteins were expressed with IPTG. As a result, GST fusion proteins with GRA225-105, GRA339-138, ROP2324-561, and MIC21-284 domains had respectively higher value of IgG avidity. The rGST-GRA225-105 and rGST-GRA339-138 were soluble, while rGST-ROP2324-561 and rGST-MIC21-284 were not. GRA231-71, intrinsically unstructured domain (IUD) of GRA2, was used as a linker to enhance the solubility. The rGST-GRA231-71-ROP2324-561, a chimeric protein, appeared to be soluble. Moreover, rGST-GRA231-71-MIC21-284 was also soluble and had higher IgG avidity comparing to rGST-MIC21-284. These 4 highly expressed and water-soluble recombinant antigenic proteins may be promising candidates to improve the serodiagnosis of toxoplasmosis in addition to the major surface antigen of SAG1.

Abstract
The precise diagnosis of an acute and recent Toxoplasma infection in pregnant women and the newborn child is important before treatment. This study describes a new Toxoplasma gondii IgG avidity test based on a combination of recombinant GRA1, GRA7 and SAG1 antigens and shows that this test is useful for diagnostic purposes and may replace the lysed, whole-cell antigens. Although more sera need to be tested, the results obtained here suggest that the IgG avidity test performed with rec-antigens correlated more with the stage of a T. gondii infection than the IgG avidity results obtained with the lysed, whole-cell antigen test, the VIDAS Toxo IgG avidity (bioMérieux).
