Abstract:

AbstractThe most common and widespread liver flukes of the genus Fasciola are Fasciola hepatica and F. gigantica. Adults of both species occur in many domestic ruminants and in humans and can cause serious disease. The differential diagnosis of these flukes infection is very important because of their different transmission and epidemiological characteristics. A simple and rapid PCR-restriction fragment length polymorphism (RFLP) assay, using the common restriction enzymes AluI and RsaI, is described to distinguish between both fasciolid species. After the digestion of the mitochondrial cytochrome c oxidase 1 (CO1) PCR product with the restriction enzyme AluI, the RFLP profile obtained from F. hepatica revealed two fragments, whereas F. gigantica was not cut. The RsaI digestion generated two fragments from F. gigantica, whereas it did not cut the PCR product from F. hepatica. Results were confirmed with CO1 sequence analysis of both F. hepatica and F. gigantica. The present study suggests that the PCRRFLP method described here can be used for the proper identification of Fasciola species.

Abstract:

AbstractFascioliasis is an important food-borne parasitic disease caused by the two trematode species, Fasciola hepatica and Fasciola gigantica. The phenotypic features of fasciolid adults and eggs infecting buffaloes inhabiting the Central Punjab area, Pakistan, have been studied to characterize fasciolid populations involved. Morphometric analyses were made with a computer image analysis system (CIAS) applied on the basis of standardized measurements. Since it is the first study of this kind undertaken in Pakistan, the results are compared to pure fasciolid populations: (a) F. hepatica from the European Mediterranean area; and (b) F. gigantica from Burkina Faso; i.e. geographical areas where both species do not co-exist. Only parasites obtained from bovines were used. The multivariate analysis showed that the characteristics, including egg morphometrics, of fasciolids from Central Punjab, Pakistan, are between F. hepatica and F. gigantica standard populations. Similarly, the morphometric measurements of fasciolid eggs from Central Punjab are also between F. hepatica and F. gigantica standard populations. These results demonstrate the existence of fasciolid intermediate forms in endemic areas in Pakistan.

Abstract:

The aim of this thesis was to characterize Kunitz-type (KT) protease inhibitors expressed by the helminth parasite Fasciola hepatica during infection of the mammalian host. KT inhibitors have traditionally been considered serine protease inhibitors. A P1 residue, typically Lys or Arg, within a reactive loop, determines serine protease inhibition specificity. Recombinant KT inhibitor expression was carried out for the gene identified in F. hepatica (fhktl) that encodes an uncommon P1 Leu residue. Inhibition studies found that FhKT1 did not inhibit serine proteases, but did inhibit cysteine protease, particularly cathepsin L-like cysteine proteases. Molecular modelling predicted that residues P1 Leu15 to P4’ Arg19 of the KT inhibitor interact with the S2 and S2’ pockets of the cysteine protease. Interrogation of the F. hepatica draft genome identified seven KT inhibitors in this parasite, which were found to fall into 5 distinct groups. The fhktl group is made up of three highly similar KT genes, two with a P1 Leu residue (fh ktl.1 and fh k tl.2), but another with a P1 Arg (fh ktl.3). Recombinant FhKT1.3was found to inhibit cysteine proteases, as well as trypsin. Transcriptomic analysis revealed that the fhkt genes are temporally regulated across mammal-associated parasite life-cycle stages, with only the fhktl group expressed at all stages. The fhktl group was also found to be the most highly expressed, as well as the only FhKTs secreted by the parasite. Based on the inhibition specificity of FhKT1 inhibitors, their constituative expression, tissue-specific localization and their presence in parasite secretions, these inhibitors are proposed to be multi-functional, with a primary role in the regulation of F. hepatica and host cathepsin L- like cysteine proteases. Based on the ability of FhKT1.3 to inhibit trypsin, this inhibitor could also function in parasite defence. FhKT1 represents a target at which a novel drug or vaccine could be directed.

Abstract:

5'-Deoxy-5'-methylthioadenosine (MTA) is derived from s-adenosylmethionine (AdoMet) during the synthesis of the polyamines spermidine and spermine. Methionine can be regenerated from MTA by one of two mechanisms. In mammalian cells and some microorganisms, MTA is degraded to adenine and 5-methylthioribose-1-phosphate (MTR-1-P) via MTA phosphorylase. In certain other microbes, however, MTA is catabolized in two steps; first to adenine and 5-methylthioribose (MTR) via MTA nucleosidase followed by conversion of MTR to MTR-1-P via MTR kinase. This study was to demonstrate the presence of MTA nucleosidase or MTA phosphorylase in both redia containing cercariae and adult Fasciola hepatica Linnaeus, 1758. If MTA nucleosidase was present, it was wanted to determine if MTR kinase was also present. The phosphate-dependent cleaving activity of MTA phosphorylase was demonstrated in the cell-free extracts of adult Fasciola hepatica along with an unidentified MTR metabolizing activity. Redia containing cercariae showed MTA nucleosidase and MTR kinase activity.

Arquivos Portugueses das Ciências Biológicas. Tomo XXXVI (in press)
Fasciola hepatica is a parasitic trematode with debilitating and socio-economically devastating effects. At present near to 600 million animals and 2.4 million people in the entire world suffer from fascioliasis. Genetic characterization is of the utmost importance to an efficient epidemiologic control of helminth infections. In the present study we aimed to provide the first insights into the genetic variability of F. hepatica in Portugal. 47 isolates from different hosts (cattle and sheep) and geographical locations (Beja, Castelo Branco, Coimbra, Évora, Faro, Leiria, Lisboa, Portalegre, Santarém and Setúbal) were analyzed through Random Amplified Polymorphic DNA-Polymerase Chain Reaction (RAPD-PCR), Restriction Fragment Length Polymorphism (RFLP) and sequencing of NADH dehydrogenase subunit 1 (nad1) gene, cytochrome c oxidase subunit 1 (cox1) gene and Internal Transcribed Spacers (ITS) region. RAPD-PCR and RFLP patterns were similar for all the analyzed samples, despite their host and geographical origin. Nucleotide sequencing revealed low levels of genetic diversity within Portuguese isolates and no direct correlation was observed between haplotype and geographical location or host. Phylogenetic analysis revealed a high similarity within samples from Mediterranean countries, such as Portugal, Spain, Tunisia, Algeria and Egypt, possibly due to livestock import/export trade between these countries. Moreover, Portugal presents a low risk of fascioliasis drug-resistance.

Abstract:

The excretions, secretions and surface components of a parasite are by their nature centrally involved in the host/parasite interaction. Rats, like cattle, are capable of developing resistance to fasciolosis after primary infection and are therefore considered a suitable laboratory model for cattle. The objective of this study was to characterise the excretory/secretory (ES) and surface components of Fasciola hepatica as it develops in the rat, and to identify those components involved in the host/parasite interaction that may have diagnostic and/or protective value. Three trials were conducted during the study in order to produce supplies of rat antiserum which was protective against F. hepatica, Rats were infected with either 10 (first trial) or 20 (second and third trials) F. hepatica metacercariae as information from the literature indicated that these doses were adequate to stimulate the production of protective antibody levels. The rat sera from the three trials were checked for the presence of protective antibodies by passive protection studies. Only in the latter two trials was the level of protection conferred on recipient statistically significant. The probable causes for the lack of significant protection in trial 1 are discussed. The silver stained protein profiles of ES from newly excysted (D0) flukes and one-day old (D1) flukes were characteristic and were similar to each other. The ES of parenchymal 14-day old (D14) and adult (D56) flukes were markedly different from D0 and D1 flukes but similar to each other. The silver stained total ES protein profiles of the developing flukes were very different from the total biosynthetically (³⁵S-methionine) radio-labelled ES protein profiles. Possible reasons for this are discussed. However, as with the total silver stained ES protein profiles there were clear changes in the profiles of the biosynthetically radio-labelled ES as the flukes developed. It is suggested that these differences in the ES products may reflect the changing environment and activities of the flukes. The possible functions of the changing ES products are discussed.

Abstract:

This study reports the localization and partial characterization of thioredoxin from the parasitic trematode Fasciola hepatica. Snails (Pseudosuccinia columella) were raised in culture and infected with F. hepatica so that Western blotting and immunohistochemical techniques could be utilized to determine the presence of thioredoxin in different stages of the parasites development. The results of these experiments showed that thioredoxin was present in the tegument, gut epithelium, excretory canal epithelium and sperm, of the adult parasite as well as in the tegument and gut of the redia and cercaria intermediate stages. In situ hybridization was used to determine the localization and possible differential mRNA expression of two different F. hepatica thioredoxin isotypes (Fh2020.A and Fh2020.SL) in the adult parasite. The in situ hybridization results showed that both isotypes are expressed in the tegument and gut epithelium. Fh2020.A stains with a greater intensity possibly demonstrating a difference in the amount of expression between the two isotypes. Recombinant F. hepatica thioredoxin expressed in bacteria using the pMAL Protein Fusion and Expression System was used to test its affects on the production of super oxide anion by murine peritoneal macrophages, bovine monocyte-derived macrophages and bovine whole blood neutrophils, and nitric oxide production by mouse peritoneal macrophages and bovine monocyte-derived macrophages. The results of the cellular assays were not definitive due to the fact that the maltose binding protein (MBP) moiety of the recombinant thioredoxin, when tested alone, increased production of nitric oxide by bovine monocyte-derived macrophages. Consequently, since the MBP could not be effectively separated from the thioredoxin portion of the recombinant, allowing the thioredoxin affects to be tested independently, no true conclusions regarding its affects on the host immune cells tested could be drawn. This is the first report of the localization of thioredoxin in both the adult F. hepatica as well as in specific intermediate stages of the parasite. These studies demonstrate the possible affects that a protein tag can have on experimental results and demonstrate how such data may be interpreted when a non-cleaved recombinant protein is used in cellular or other assays when compared to native or cleaved recombinant proteins.

Abstract:

Fasciola hepatica is responsible for substantial economic losses and animal welfare issues within the agricultural sector worldwide. The increasing incidence of fasciolosis, coupled with the emergence of flukicide resistance, makes vaccination an attractive alternative control strategy. Hidden antigens extracted from the gut of blood feeding parasites have proven to be excellent vaccine candidates against haematophagous parasites, most notably Haemonchus contortus and Rhipicephalus (Boophilus) microplus. Here, as a first step towards a prototype liverfluke vaccine an attempt to identify hidden gut antigens in F. hepatica was made. Proteomic analysis on extracts of adult F. hepatica was used to identify molecules exclusively found within the membrane-bound fraction including four proteases; cathepsin B2, legumain-2, a putative lysosomal pro-x-carboxypeptidase precursor and a saposin-like protein. Histological sections of adult F. hepatica were screened with a panel of 21 lectins to identify those with an affinity for glycoproteins on the parasite’s gut and to inform subsequent lectin affinity chromatography. Seven lectins showed affinity for the gut region, with peanut (PNA) and jacalin (JAC) lectins binding to glycoproteins on either the gastrodermal cells or gut lamellae, respectively. PNA and JAC were then used to purify glycoproteins from the crude S3 extract by affinity chromatography. The resultant fractions were separated by SDS-PAGE and the protein profiles analysed by mass spectrometry. The enriched lectin-binding fractions shared a number of proteins but one of note that was exclusively identified in the PNA-binding fraction was a cathepsin D-like aspartyl protease, which had not previously been studied in F. hepatica. The proteolytic activities of three somatic extracts of adult F. hepatica were therefore investigated. The ability of the respective fractions to digest haemoglobin, a potential food source, was measured in the presence/absence of class-specific enzyme inhibitors. These analyses confirmed the presence of cathepsin D-like aspartyl protease activity capable of digesting haemoglobin optimally at pH 2 - 2.5. Further characterisation of the cathepsin D-like aspartyl (FhCatD) protease revealed it to be highly conserved within trematodes, to be localized to the gastrodermis of immature (10 day) and adult fluke, and to be more highly expressed, at the RNA level, in the Newly Excysted Juveniles (NEJ) than adult stages. Western blot analysis of native somatic extracts, enriched lectin-binding fractions and recombinant FhCatD using antisera from naturally infected sheep, showed some recognition of the recombinant FhCatD but did not provide clear evidence that the cathepsin D is strongly antigenic during natural infection.

Abstract:

This work is based on helminthological data of amphibians, collected since 2013 until 2020, in the Republic of Moldova. The investigations on anura amphibians were conducted in the laboratory of Parazitology and Helminthology of the Institute of Zoology. One of the most common parasitic diseases in ruminants is fasciolosis, caused by the trematode Fasciola hepatica species. The results of parasitological research showed that adult cattle were infected with fascioles in 66.4% of cases, and young cattle - in 46.1% of cases. This is largely due to the grazing of animals of different species and ages in limited areas.The presence of the trematode species Haplometra cylindracea was established in 78% of cases in the amphibians in the Ranidae and Bufonidae families (Rana ridibunda, Rana lessonae, Rana temporaria, Bufo viridis). The results of laboratory helminthological investigations have shown that the relationships between the Fasciola hepatica miracidium and the Haplometra cylindracea miracidium are antagonistic. Amphibians of the Ranidae and Bufonidae families (Rana ridibunda, Rana lessonae, Rana temporaria, Bufo viridis) infested with Haplometra cylindracea tremateda may play an important role in the prophylaxis of fasciolosis.

Abstract:

Introdução: O aumento da população de cães e gatos em áreas urbanas tem papel epidemiológico importante na contaminação do solo de áreas públicas e na disseminação de infecções pelos mais variados gêneros de parasitos. A confirmação da presença de parasitos de importância médico veterinária serve de alerta a população humana a respeito dos riscos em que a mesma encontra-se exposta. Objetivo: Neste sentido, esta pesquisa teve como escopo principal avaliar a incidência de ovos, cistos e/ou larvas de parasitos no solo de bairros do município de Tucuruí, no Pará. Material eMétodos: Foram coletadas 15 amostras de solo de vias públicas e domicílios de cada bairro, no período de Novembro a Dezembro de 2021, totalizando 30 amostras. Após a coleta, as amostras foram acondicionadas em isopor, devidamente identificadas e encaminhadas ao Laboratório de Microbiologia e Parasitologia do IFPA/Campus Tucuruí. Em seguida, foram processadas pela técnica flutuação no açúcar (método de Sheather) e observadas ao microscópio óptico nas objetivas de 10X e 40X. Resultados: Do total de amostras coletadas, 50% (15 amostras) foram positivas para parasitas de solo com potencial zoonótico. O bairro com maior contaminação foi o Cohab (10 amostras positivas). Os principais protozoários encontrados nas amostras positivas foram: Iodamoeba butschlii (11,76%); Balantidium coli (8,82%); Hymenolepis diminuta (5,88%) e Entamoeba sp. (2,94%). Os helmintos encontrados foram: Taenia sp. (20,58%); Ancylostoma sp.(11,76%); Toxocara sp. (11,76%); Ascaris sp. (5,88%); Dipylidium caninum (5,88%); Trichuris vulpis (5,88%); Enterobius vermicularis (2,94%), Fasciola hepatica (2,94%) e Strongyloides stercoralis (2,94%). Conclusão: Os achados desse estudo comprovaram que em vias públicas e domicílios dos bairros estudados em Tucuruí, há parasitos com potencial zoonótico, ressaltando a necessidade de implantar ações integradas ligadas à saúde pública para a conscientização da população humana quanto às zoonoses, bem como suas formas de transmissão e prevenção.
