Biochem Biophys Rep 2023; 33:101424. [PMID: 36660764 PMCID: PMC9843214 DOI: 10.1016/j.bbrep.2023.101424] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/23/2022] [Revised: 01/04/2023] [Accepted: 01/05/2023] [Indexed: 01/11/2023] Open
Abstract
Background Understanding the pathogenesis of animal trypanosomiasis can be improved by studying the genetics of bovine trypanosomes. Pathogenic animal trypanosomes are a major impediment to livestock production, with negative economic consequences spreading beyond Sub-Saharan Africa to subtropical regions of Northern Africa, Southeast Asia, and Central and South America. An atypical K1 strain of Trypanosoma evansi (T. evansi) isolates from infected cattle in Nigeria was analyzed. The therapeutic effect of phenolic-rich compounds on the histopathology of wistar rats infected with the K1 strain was studied. Methods The K1 strain T. evansi was analyzed molecularly using PCR and sequence analysis of the Spacer-1 ribosomal RNA gene. To assess the evolutionary relationship, this was phylogenetically compared to other species studied in different parts of the world. Thirty adult male wistar rats were divided into six groups of five each. Animals in group A served as the standard control (not infected). Group B animals were infected but not treated. Group C animals were infected and given 3.5 mg/kg body weight of the standard drug diminazene aceturate. Animals in groups D, E, and F were infected and treated with phenolic-rich compounds isolated from Brassica oleracea (B. oleracea) at concentrations of 100, 200, and 400 mg/kg body weight, respectively. The phytochemicals were extracted using standard analytical procedures, and GCMS analysis revealed the presence of phenolic-rich compounds. The animals were given 0.2 mg/ml trypanosome intraperitoneally, diluted with normal saline. The vital organs of the animals were harvested and histologically examined. Results The nested PCR amplification of the trypanosome's ITS-1 region revealed a DNA amplicon of 627 base pairs. The rRNA nucleotide sequence was deposited in GenBank under the accession number MN462960. Basic Local Alignment search of the obtained ITS-1 rRNA sequences revealed that the K1 strain trypanosome and other strains from different regions have an evolutionary relationship. The phenolic-rich compounds had protective effects on the organs of infected animals, resulting in a decrease in parasitemia levels. They have anti-trypanosome activities at the minimum and maximum effective doses of 200 and 400 mg/kg body weight, respectively. Conclusions The K1 strain T. evansi was isolated from naturally infected cattle in this study. The results indicate that phenolic-rich compounds have anti trypanosoma activities capable of healing organ damage caused by trypanosomiasis.

Abstract
Background and Aim Animal trypanosomiasis is a major contributor to agricultural and economic losses, especially in sub-Saharan Africa. We have shown that some animal species expressed genes that are significant players in immune response to bovine trypanosomosis, impeding signs and symptoms of the disease. We hypothesize that such animals are contributors to disease transmission dynamics and severe outcomes. Therefore, this study aims to ascertain trypanosome species diversity in cattle and their potential role as reservoirs for the transmission of human disease. Materials and Methods We performed a molecular genotyping of trypanosome internal transcribed spacer 1 (ITS-1) and 18S ribosomal RNA genes on genomic DNA extracts from randomly sampled N'Dama cattle from slaughterhouses in Nigeria. We identified trypanosome species circulating among the animals through polymerase chain reaction and genomic sequencing. We performed multiple sequence alignments as well as conducted a phylogenetic relationship between identified species. Results In all, 9 of 127 (7.1%) samples were positively amplified (band sizes ranging from 250 bp to 710 bp), including an isolate with two distinct bands (700 and 710 bp), indicating two trypanosome types. Sequence similarity and homology analysis identified four species, namely: Trypanosoma vivax, Trypanosoma congolense forest type, T. congolense savannah type, and Trypanosoma brucei. Interestingly, one of the bands, additionally verified by nucleotide sequencing, was identified as a human trypanosome (Trypanosoma brucei gambiense), confirming our hypothesis that cattle are potential reservoir hosts for human trypanosomes. Conclusion Overall, we observed different trypanosome species in our study area, with animals on the same farm infected with multiple species, which could complicate treatment and disease control strategies. Finding human trypanosome species strengthens the argument that disease transmission dynamics are modulated by other vertebrates, further complicating control programs.

Molecular identification of bloodmeal sources and trypanosomes in Glossina spp., Tabanus spp. and Stomoxys spp. trapped on cattle farm settlements in southwest Nigeria. MEDICAL AND VETERINARY ENTOMOLOGY 2019; 33:269-281.

Abstract
The interactions of host, vector and parasite in bovine trypanosomiasis transmission cycles in southwest Nigeria are not yet well understood. Trypanosoma (Trypanosomatida: Trypanosomatidae) species infection prevalences and bloodmeal sources were determined in transmitting vectors of the genera Glossina (Diptera: Glossinidae), Tabanus (Diptera: Tabanidae) and Stomoxys (Diptera: Muscidae) collected using Nzi traps in cattle settlements in southwest Nigeria. Sequenced cytochrome B mitochondrial DNA segments obtained from vector digestive tracts identified bloodmeal sources from eight host species, namely human, cattle, hippopotamus, giraffe, gazelle, spotted hyena, long-tailed rat and one unidentified species. Overall, 71.1% [95% confidence interval (CI) 63.0-78.1], 33.3% (95% CI 21.9-47.0) and 22.2% (95% CI 16.2-29.9), respectively, of Glossina, Tabanus and Stomoxys flies were positive for trypanosomes. The observed trypanosome species were Trypanosoma vivax, Trypanosoma congolense, Trypanosoma brucei, Trypanosoma evansi, Trypanosoma simiae and Trypanosoma godfreyi. Trypanosome DNA was more prevalent in tsetse (34.8% Tr. vivax, 51.1% Tr. b. brucei, 5.2% Tr. congolense, 4.4% Tr. simiae and 24.4% mixed infections) than in other flies and the main determinants in all flies were seasonal factors and host availability. To the best of the present group's knowledge, this is the first report of Trypanosoma species in Tabanus and Stomoxys flies in Nigeria. It indicates that vector control programmes should always consider biting flies along with tsetse flies in the control of human and animal trypanosomiasis.

New insights from Gorongosa National Park and Niassa National Reserve of Mozambique increasing the genetic diversity of Trypanosoma vivax and Trypanosoma vivax-like in tsetse flies, wild ungulates and livestock from East Africa. Parasit Vectors 2017; 10:337. [PMID: 28716154 PMCID: PMC5513381 DOI: 10.1186/s13071-017-2241-2] [Citation(s) in RCA: 18] [Impact Index Per Article: 2.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/18/2017] [Accepted: 06/11/2017] [Indexed: 12/22/2022] Open
Abstract
BACKGROUND Trypanosoma (Duttonella) vivax is a major pathogen of livestock in Africa and South America (SA), and genetic studies limited to small sampling suggest greater diversity in East Africa (EA) compared to both West Africa (WA) and SA. METHODS Multidimensional scaling and phylogenetic analyses of 112 sequences of the glycosomal glyceraldehyde phosphate dehydrogenase (gGAPDH) gene and 263 sequences of the internal transcribed spacer of rDNA (ITS rDNA) were performed to compare trypanosomes from tsetse flies from Gorongosa National Park and Niassa National Reserve of Mozambique (MZ), wild ungulates and livestock from EA, and livestock isolates from WA and SA. RESULTS Multidimensional scaling (MDS) supported Tvv (T. vivax) and TvL (T. vivax-like) evolutionary lineages: 1) Tvv comprises two main groups, TvvA/B (all SA and WA isolates plus some isolates from EA) and TvvC/D (exclusively from EA). The network revealed five ITS-genotypes within Tvv: Tvv1 (WA/EA isolates), Tvv2 (SA) and Tvv3-5 (EA). EA genotypes of Tvv ranged from highly related to largely different from WA/SA genotypes. 2) TvL comprises two gGAPDH-groups formed exclusively by EA sequences, TvLA (Tanzania/Kenya) and TvLB-D (MZ). This lineage contains more than 11 ITS-genotypes, seven forming the lineage TvL-Gorongosa that diverged from T. vivax Y486 enough to be identified as another species of the subgenus Duttonella. While gGAPDH sequences were fundamental for classification at the subgenus, major evolutionary lineages and species levels, ITS rDNA sequences permitted identification of known and novel genotypes. CONCLUSIONS Our results corroborate a remarkable diversity of Duttonella trypanosomes in EA, especially in wildlife conservation areas, compared to the moderate diversity in WA. Surveys in wilderness areas in WA may reveal greater diversity. Biogeographical and phylogenetic data point to EA as the place of origin, diversification and spread of Duttonella trypanosomes across Africa, providing relevant insights towards the understanding of T. vivax evolutionary history.
