Dynamics of prevalence and distribution pattern of avian Plasmodium species and its vectors in diverse zoogeographical areas - A review.

This article aimed to provide a comprehensive list of the common avian Plasmodium parasites in the birds and mosquitoes, to specify the common Plasmodium species and lineages in the selected regions of West of Asia, East of Europe, and North of Africa/Middle East, and to determine the contribution of generalist and host-specific Plasmodium species and lineages. The final list of published infected birds includes 146 species, among which Passer domesticus was the most prevalent in the studied areas. The species of Acrocephalus arundinaceus and Sylvia atricapilla were reported as common infected hosts in the examined regions of three continents. The highest numbers of common species of infected birds between continent pairs were from Asia and Europe, and no common record was found from Europe and Africa. The species of Milvus migrans and Upupa epops were recorded as common species from Asia and Africa. The lineage of GRW11 and species of P. relictum were the most prevalent parasites among all the infection records in birds. The most prevalent genus of vectors of avian malaria belonged to Culex and species of Cx. pipiens. The lineage SGS1 with the highest number of occurrence has been found in various vectors comprising Cx. pipiens, Cx. modestus, Cx. theileri, Cx. sasai, Cx. perexiguus, Lutzia vorax, and Culicoides alazanicus. A total of 31 Plasmodium species and 59 Plasmodium lineages were recorded from these regions. SGS1, GRW04, and GRW11, and P. relictum and P. vaughani are ...

Authors: Abdeta D, Kebede N, Giday M, Terefe G, Abay SM Abstract Microbial resistance to the few conventional antitrypanosomal drugs, increasing resistance of vectors to insecticides, lack of effective vaccines, and adverse effects of the existing antitrypanosomal drugs justify the urgent need for effective, tolerable, and affordable drugs. We assessed antitrypanosomal effects of the hydromethanolic extract of Echinops kebericho Mesfin roots against Trypanosoma congolense field isolate using in vitro and in vivo techniques. Parasite load, packed cell volume (PCV), body weight, and rectal temperature in Swiss albino...

Conclusion: This study demonstrates that the crude extract of A. hispidum DC, one of the plants used traditionally to treat malaria, inhibits the growth of P. falciparum in vitro and could be a potential source of antimalarial drug. The report has highlighted genotoxic and cytotoxic effects of the selected plant extracts on human leukocytes as well. PMID: 33029160 [PubMed]

(Nagoya University) Using the model Orobanchaceae parasitic plant Phtheirospermum japonicum, scientists have discerned the molecular mechanisms underlying plant parasitism and cross-species grafting, pinpointing enzymeβ-1,4-glucanase (GH9B3) as an important contributor to both phenomena. Targeting this enzyme may help control plant parasitism in crops.

In this study, we present a new method for the simultaneous detection of CXCR4, mesodermal markers and NCCs markers during chicken embryo developmental stages HH18 –HH25 by combining double whole-mount in situ hybridization (ISH) and immunostaining on floating vibratome sections. The simultaneous detection of CXCR4 and markers for the mesodermal and neural crest cells in multiple labelling allowed us to compare complex gene expression patterns and it could b e easily used for a wide range of gene expression pattern analyses of other chicken embryonic tissues. All steps of the procedure, including the preparation of p...

Conclusions: The low prevalence of asymptomatic malaria parasite carriage by the children living in the Cape Coast Metropolis suggests that the malaria control interventions in place in CCMA are highly effective and that additional malaria control interventions are required for the KEEA district to reduce the prevalence of asymptomatic malaria parasite carriers. No molecular evidence of P. ovale and P. vivax was identified in the afebrile children sampled from the selected schools. PMID: 33029151 [PubMed]

AbstractThe historically southeastern mosquito speciesCulex erraticus has over the last 30  years undergone a marked expansion north. We evaluated this species’ potential to participate in local disease cycles in the northeastern USA by identifying the vertebrate sources of blood inCx. erraticus specimens from New Jersey. We found that the majority of bloodmeals (92.6%) were derived from birds, followed by 6.8% from mammals (of which half were human), and a single amphibian bloodmeal from a spring peeper (0.56%). Medium- and large-sized water birds from the order Pelecaniformes made up 60.4% of the bird species ...

Publication date: August 2017 Source:Microbial Pathogenesis, Volume 109 Author(s): Seema Patel Zoonotic diseases are a subset of infectious diseases, which account for enormous morbidity and mortality. Pathologies like malaria, rabies, Lyme disease, leptospirosis, avian flu etc. are microbe- and parasite-caused ailments, where the etiological agents are introduced into or on the human body via ticks, mosquitoes, birds, rodents, bats, and deer, among other members of kingdom Animalia. While some of the zoonotic diseases are well-investigated and caution taken against, a lot many are yet to be recognized. This ignorance cos...

Mepron, a thick liquid antimicrobial drug used to treat Babesia and malaria, as well as a fungal infection called Pneumocystitis carinii. In 2011, the United Kingdom stopped requiring that dogs brought into the country be inspected for ticks. Earlier this year, several dogs tested positive for babesia, a malaria-like disease transmitted to ticks that previously had only been found in foreign. These dogs had never left the U.K. While babesiosis is a new worry to U.K. dog owners, it's been a threat to human beings for years -- it just hasn't become a health-scare-of-the-week like Zika, West Nile, avian and swine flu. Most...
