In addition to its effects on mycobacterial diseases, the information has shown the protection effect of BCG in helminthic diseases. In the current review, the role of BCG vaccine in non-specific protection helminthic infection is reviewed. In human alveolar echinococcosis (AE), treatment with BCG enhances host's innate immune response against the parasite via the number and activation of monocytes. In cysticercosis, despite the enhancement of Th1-biased immune responses by coadministration of rcC1 plus BCG-DNA, the level of induced protection did not increase compared to immunization with rcC1 antigen alone. Also, pretreatment of mice with live BCG vaccine induced a high level of protection against subsequent parasite infection with Taenia taeniaeformis. The reduction of the parasite burden in mice infected with Mesocestoides corti that received two doses of BCG post-infection demonstrated the therapeutic effect of BCG. The protective potential of the schistosomula/BCG vaccine against Schistosoma japonicum in sheep study showed a reduction in the number of adult worms and mean faecal egg counts post-challenge. In trichinellosis, BCG can induce hyperplasia of the reticuloendothelial system and activation of macrophages in mice. Therefore, these data revealed that BCG vaccination can exert non-specific protective effects for the prevention of diseases other than tuberculosis. Medicinal doses of BCG may be considered a new approach to the treatment of helminth infections.","PeriodicalId":7987,"journal":{"name":"Annals of parasitology","volume":"69 ","pages":"49-59"},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138443591","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Seventy-six samples of F. hepatica and 28 F. gigantica were collected from the slaughterhouses of endemic regions in Iran. Following a comprehensive analysis of the mitochondrial complete sequences of both F. hepatica and F. gigantica, the extracted DNAs from all samples were used as templates in multiplex PCR reactions containing two sets of primers specific for cytochrome c oxidase I (cox I) gene of both species. In a parallel experiment, PCR-RFLP was performed for each sample using internal transcribed spacer (ITS1) sequence. Furthermore, following a PCR amplification for cox I gene, the amplicons were purified for sequencing. To assess the validity of the multiplex PCR approach, the obtained data from the multiplex PCR and PCR-RFLP experiments were compared with each other. By sequence analysis of 104 samples, 76 and 28 samples were identified as F. hepatica and F. gigantica, respectively. Results revealed 100% and 92% of accuracy as for multiplex PCR and PCR-RFLP. The designed multiplex PCR strategy offers a valid alternative approach to the conventional methods with distinctive features including convenience, cost-effectiveness, time-saving (3 hours from sampling to obtain final results) and high efficacy.","PeriodicalId":7987,"journal":{"name":"Annals of parasitology","volume":"69 ","pages":"67-74"},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139073167","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A total of 598 parasite specimens were recovered from nine parasitized hosts, belonging to four taxonomic groups: one Myxozoa (Henneguya sp.); four Monogenea (Dactylogyridae gen. sp., Jainus sp., Urocleidoides sp. 1 and Urocleidoides sp. 2); one Nematoda (Procamallanus (Spirocamallanus) inopinatus) and two Copepoda (Ergasilus sp. and Gamispatulus schizodontis). Previous studies reported five parasitic associations in L. piau: two nematodes (P.

For the first time, this study records myxozoan and monogeneans parasitizing the host L. piau.

The primary objective of the present study was to made a comparison between healthy control subjects (group 1), Blastocystis-positive subjects (group 2), subjects with irritable bowel syndrome (IBS) who were Blastocystis-negative (group 3), and IBS patients who were Blastocystispositive (group 4) regarding the haematological indices. From each participant, blood has been collected and the complete blood count (CBC) has been measured. The current study also was designed to evaluate the correlation between blastocystosis and six selected hemogram parameters [monocyte-to-lymphocyte ratio (MLR), neutrophil-tolymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), red cell distribution width (RDW), platelet distribution width (PDW), and mean platelet volume (MPV)]. The results revealed that the total numbers of lymphocytes and platelets decreased significantly (P<0.0001), while the numbers of monocytes (P<0.0001) and neutrophils (P<0.0001) increased significantly in the bloods of IBS patients and non-IBS subjects who were infected with Blastocystis parasites in comparison with the healthy subjects in the control group. In addition, our results revealed for the first time that the levels of NLR, MLR, PLR, RDW, PDW and MPV were significantly higher (P=0.05-0.0001) in the bloods of IBS patients and non-IBS subjects who were infected with Blastocystis parasites than in their Blastocystis-negative counterparts. In conclusion, we believe that the levels of these hemogram parameters can be used as novel markers of blastocystosis. In addition, this study revealed that the infection with Blastocystis parasites had a significant impact on the haematological indices in both IBS patients and non-IBS individuals.","PeriodicalId":7987,"journal":{"name":"Annals of parasitology","volume":"68 3","pages":"491-500"},"PeriodicalIF":0.0,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"10460985","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
