Anemia is estimated to affect half the school-age children and adolescents in developing countries. The main causes are parasitic infections, malaria, and low iron intake. This study aimed to describe the prevalence of anemia, parasitic infections, and nutritional status of children attending public primary schools in Aracaju, Northeast Brazil. Of 360 students, 26.7% were anemic, and prevalence was higher in children under 8 and over 15 years of age. Overall prevalence of intestinal parasites was 42%, with Ascaris lumbricoides (28.7%), Trichuris trichiura (15.6%), and hookworm (1.7%) most freq

&lt;em&gt;Abstract.&lt;/em&gt;—A new checklist of 36 metazoan parasites recorded in European eels &lt;em&gt;Anguilla anguilla &lt;/em&gt;in Ireland is presented and reviewed. Some of these parasite taxa are eel specialists but most utilize a range of fish hosts. Many were accidentally brought to Ireland during fish introductions. Changing distributions of preferred intermediate hosts have affected some parasite species. Commercial transport of eels has been implicated in the introduction and spread of several potentially pathogenic parasites, including the Asian nematode &lt;em&gt;Anguillicola crassus&lt;/em&gt;. The current status of this and two &lt;em&gt;Pseudodactylogyrus &lt;/em&gt;species, similarly introduced to Ireland, is discussed. Analysis of parasite assemblages of Irish eel populations indicates that individual host characteristics, such as size and diet, are important at the infra-community level. Likewise, variation in biotic and abiotic features of ecosystems is reflected in composition and structure of eel parasite component communities. Environmental changes, such as eutrophication and species introductions, were found to affect eel parasite assemblages. Better regulation of fish introductions and translocations is needed to protect the ecological integrity of Ireland’s freshwater systems and to avoid economic damage by nonindigenous parasites. Restrictions on live eel transport and on eel stocking programs may be necessary to protect recreational fisheries and the Irish aquaculture industry.

Abstract:
Malaria is a leading public health problem in tropical and subtropical countries of the world. In 2019, there were an estimated 229 million malaria cases and 409, 000 deaths due malaria in the world. The objective of this chapter is to discuss about the different Plasmodium parasites that cause human malaria. In addition, the chapter discusses about antimalarial drugs resistance. Human malaria is caused by five Plasmodium species, namely P. falciparum, P. malariae, P. vivax, P. ovale and P. knowlesi. In addition to these parasites, malaria in humans may also arise from zoonotic malaria parasites, which includes P. inui and P. cynomolgi. The plasmodium life cycle involves vertebrate host and a mosquito vector. The malaria parasites differ in their epidemiology, virulence and drug resistance pattern. P. falciparum is the deadliest malaria parasite that causes human malaria. P. falciparum accounted for nearly all malarial deaths in 2018. One of the major challenges to control malaria is the emergence and spread of antimalarial drug-resistant Plasmodium parasites. The P. vivax and P. falciparum have already developed resistance against convectional antimalarial drugs such as chloroquine, sulfadoxine-pyrimethamine, and atovaquone. Chloroquine-resistance is connected with mutations in pfcr. Resistance to Sulfadoxine and pyrimethamine is associated with multiple mutations in pfdhps and pfdhfr genes. In response to the evolution of drug resistance Plasmodium parasites, artemisinin-based combination therapies (ACTs) have been used for the treatment of uncomplicated falciparum malaria since the beginning of 21th century. However, artemisinin resistant P. falciparum strains have been recently observed in different parts of the world, which indicates the possibility of the spread of artemisinin resistance to all over the world. Therefore, novel antimalarial drugs have to be searched so as to replace the ACTs if Plasmodium parasites develop resistance to ACTs in the future.

Abstract:
Plasmodium falciparum, the most devastating human malaria parasite, confers higher morbidity and mortality. Although efforts have been made to develop an effective malaria vaccine, stage- and species-specific short-lived immunity crippled these efforts. Hence, antimalarial drug treatment becomes a mainstay for the treatment of malaria infection in the wake of the unavailability of an effective vaccine. Further, there has been a wide array of antimalarial drugs effective against various developmental stages of P. falciparum due to their different structures, modes of action, and pharmacodynamics as well as pharmacokinetics. The development of resistance against almost all frontline drugs by P. falciparum indicates the need for combination therapy (artemisinin-based combination therapy; ACT) to treat patients with P. falciparum. A higher pool of parasitemia under discontinuous in vivo artemisinin drug pressure in a developed humanized mouse allows the selection of artesunate resistant (ART-R) P. falciparum. Intravenously administered artesunate, using either single flash doses or a 2-day regimen, to the P. falciparum-infected human blood chimeric NOD/SCID.IL-2Rγ−/− immunocompromised (NSG) mice, with progressive dose increments upon parasite recovery, was the strategy deployed to select resistant parasites. Parasite susceptibility to artemisinins and other antimalarial compounds was characterized in vitro and in vivo. P. falciparum has shown to evolve extreme artemisinin resistance as well as co-resistance to antimalarial drugs. Overall, the present information shall be very useful in devising newer therapeutic strategies to treat human malaria infection.

Full text
Abstract:
Climate change and habitat loss alter the landscape for wildlife, resulting in shifts in geographic ranges, occupation of smaller, remnant habitat patches, or use of novel environments. These processes often lead to sympatry between species that historically were non-sympatric. Such interactions increase competition for resources and expose species to novel parasites that reduce a species’ fitness leading to wildlife declines. We explore these interactions in species of endangered North American rodents—Northern flying squirrels (Glaucomys sabrinus) and Allegheny woodrats (Neotoma magister). Northern flying squirrels are declining in the United States due to competition with its congener, southern flying squirrels (Glaucomys volans). Evidence indicates that competition is mediated by a shared nematode, Strongyloides robustus. Transmission of this nematode to northern flying squirrels is increasing due to forest fragmentation and climate change. We also note the recent discovery of S. robustus as a novel parasite and a factor in the decline of the European red squirrel (Sciurus vulgaris). Likewise, in Allegheny woodrats, shrinking landscape changes have resulted in increased range overlap with raccoons (Procyon lotor) that harbor a nematode fatal to woodrats. The subsequent transmission of this nematode, Baylisascaris procyonis, to woodrats is a contributing factor to woodrat decline throughout the Appalachians.

Toxoplasmose é uma antropozoonose causada pelo protozoário Toxoplasma gondii, parasito intracelular obrigatório que tem por hospedeiros definitivos os membros da família Felidae. Todavia, também infecta diversos outros animais de sangue quente, correspondendo aos seus hospedeiros intermediários. A enfermidade apresenta caráter cosmopolita, em grande parte devido a capacidade de disseminação e baixa especificidade parasitária. Nesse sentido, estudos epidemiológicos estimam que até 90% da população humana já teve seu sistema imunológico desafiado pelo parasito. Cumpre salientar que, após a infecção o parasito pode se instalar nos tecidos e permanecer latente por toda a vida de seu hospedeiro, podendo ser reativado quando o sistema imunológico apresentar algum comprometimento. Entre os pacientes diagnosticados com Coronavírus-19, é observada uma alta resposta imunológica de linfócitos T, porém essa mesma resposta reflete uma acentuada linfopenia, com a elevação da produção de moléculas regulatórias PD-1 que atuam no apoptose dessas células, evento conhecido como “exaustão dos linfócitos”. Em paralelo, a infecção crônica de T. gondii também possui a particularidade de estimular a expressão de PD-1 e com a exaustão dessas células imunes é possível a reativação da Toxoplasmose. O diagnóstico é feito, primordialmente, com a pesquisa de anticorpos IgM e IgG, que indicam infecção aguda e contato ou infecção crônica, respectivamente. Diante do exposto, é notória a necessidade de investigações sorológicas para busca de infecções ativas por T. gondii na população em geral, visto que, embora as campanhas de vacinação contra o Coronavírus-19 avancem ao redor do planeta, seus efeitos deletérios à saúde humana ainda não são totalmente compreendidos e, infecções mistas com o protozoário não devem ser descartadas ou negligenciadas.

Abstract:
Bananas and plantains (Musa spp.) represent the fourth most important crop in the world. In 2017, an area of 5,637,508 hectares and a production of 153 million tons were reported. Fusarium wilt caused by the fungus Fusarium oxysporum f. sp. cubense (Foc), is considered one of the most destructive diseases of bananas and plantains worldwide. The pathogen Foc causes a typical wilt syndrome on infected plants, it has a saprophytic and parasitic phase in its life cycle. Fusarium wilt is a “polycyclic” disease. This pathogen shows a relatively diverse population genetic structure for a fungus apparently of asexual reproduction and is composed of different evolutionary lineages, which has 24 groups of vegetative compatibility (VCGs), two clades and nine clonal linage. Foc is a genetically diverse pathogen, although the available evidence so far indicates that it does not use the mechanisms of sexual reproduction, such as recombination, to increase its genetic diversity. Furthermore, the population of this fungus in Southeast Asia shows a high degree of variation, suggesting that Foc lineages evolved together with their hosts in Southeast Asia. Alternatively, it has been suggested that Foc has multiple independent evolutionary origins, both within and outside of the Musaceae origin center.

Abstract:
In this chapter, enhanced symbiotic organisms search (ESOS) algorithm and hydrological cycle (HC) algorithm are projected to solve factual power loss lessening problem. Symbiotic search algorithm is based on the actions between two different organisms in the ecosystem: mutualism, commensalism, and parasitism. Exploration procedure has been initiated arbitrarily, and each organism indicates a solution with fitness value. Quasi-oppositional-based learning and chaotic local search have been applied to augment the performance of the algorithm. In this work, hydrological cycle (HC) algorithm has been utilized to solve the optimal reactive power problem. It imitates the circulation of water form land to sky and vice versa. Only definite number of water droplets is chosen for evaporation, and it is done through roulette-wheel selection method. In the condensation stage, water drops move closer, combine, and also collusion occurs as the temperature decreases.

Abstract:
The bio-efficacy of Yorkol-branded ITNs collected from Bandundu-city was assessed on the Kisumu strain and wild specimens of Anopheles gambiae. The susceptibility of the wild An. gambiae s.l. was tested to select insecticides. Adult An. gambiae s.l. sampled by PSC and HLC were screened for the presence of Plasmodium falciparum. Blood samples were diagnosed by microscopy and RDTs. ITN distributed in Bandundu-city were fully effective on the Kisumu strain, but on wild An. gambiae s.l. population (22.3 ± 11.5%). Anopheles gambiae s.l. was the main vector in Bandundu. No significant difference was observed between the entomological indices before and after the deployment of nets (OR = 0.8; p = 0.39). Wild An. gambiae s.l. populations were resistant to pyrethroids and DDT, with the restoration of the susceptibility to pyrethroids post pre-exposure to PBO. Plasmodium falciparum was the main parasite species and was found alone or mixed with. P. malariae or P. ovale. The confirmation rates by microscopy and RDT were respectively 57.9% and 53.6%. Nets deployed in Bandundu-city were not effective on wild An. gambiae s.l. populations. This operational failure is likely explained by the observed resistance to pyrethroids. In the future only PBO-net should be deployed Bandundu-city.
