obstruction (foreign body, parasites, intussusception etc.), functional obstruction (due to drugs or idiopathic megacolon), painful defecation, stress or reluctance to defecate, as well as metabolic diseases such as obesity and hyperthyroidism. This was a case of idiopathic megacolon, which resulted in obstipation. Parasite infestation may have contributed to this disease, as patient was not regularly dewormed and questionable lung pattern on radiographs suggested parasite migration.…
constitute a major important discovery for global health (Takashima et al., 2017). Malaria parasite has a complex life cycle because it has a multi-stage life cycle and at each stage, the parasite expresses hundreds of unique antigens. In addition, malaria has a highly complexed genome and sophisticated immune evasion measures (Sack et al., 2017). This complexity makes it difficult to develop a vaccine for malaria parasites (Hoffman et al., 2017). Progress during the last years has been…
IL-18, whereas non-fatal infections are accounted for by diffident initiations of Th1 cytokines (38). These responses are highly beneficial for the parasite during acute phases of the infection to keep the host cells alive. However during the chronic and latent phases, the parasite initiates immune suppression (39). Hence we hypothesize that the parasite property to alter host immune responses could be directly linked to AD progression. Through our study we find correlation factors between AD…
Naegleria Fowleri Parasites are living organisms that survive by living and feeding off another organism. There are millions of different kinds of parasites, but, this paper will discuss the biology and life-cycle of the parasitic organism, Naegleria Fowleri. It will also go into the dangerous health effects on the human body caused by an infection of the parasite. What is Naegleria Fowleri? Naegleria Fowleri, more commonly known as the “brain-eating amoeba,” are “microscopic, single-celled…
system of evolutionary changes. In isolation, parasites could not survive and reproduce, plants could not spread their seeds, viruses could not infect their host, and organisms could not form adaptations from their environment that allow them to slowly evolve into better-adapted organisms. Parasites are organisms that need a host to survive and reproduce. Without a host, there is simply no way for parasites to live. One very interesting example of a parasite is the Dicrocoelium dendriticum or…
The main topic of both the lecture and the reading is about several possible predictions on how agnostids have lived and behaved. The reading asserts three possibilities with some evidence. However, the lecture completely denies whatever mentions in the passage through several conclusive observations. First, both the…
1. The three treatment options function synergistically to benefit the patient with prostate cancer. The ionizing radiation causes single and double stranded breaks to the neoplastic cells DNA, this halts replication and cell function until it can be repaired. Etoposide is a podophyllotoxin that inhibits topoisomerase II, the enzyme responsible for unwinding the DNA. If the DNA cannot unwind, the cell will be unable to replicate, transcribe mRNA, or repair itself. If the cell is unable to repair…
that affects not only bone marrow but also leukocytes due to the fact that they are connected to the same area of the body. (Zimmermann, 2016) Without some line of defense in our bodies we become susceptible to every that bacteria, virus, disease or parasite and will inevitably…
involved. Schistosomiasis caused by Schistosoma haematobium. 1.2) Name the intermediate and definite host of this particular parasites mentioned in 1.1 Intermediate host - Freshwater snails Definite host - Humans, primates (Tierney et al., 2007) 1.3) Discuss the life cycle of this parasite mentioned in 1.1. According to Weerakoon et al.(2015), the schistosome parasite has a life cycle whereby the definite host is mammalian in nature, and the intermediate host is that of freshwater snails.…
falciparum, which causes cycles of pain, fever and chills. The parasite devotes the main phase of its life cycle in the salivary glands of the female mosquito “Anopheles Gambiae.” Malaria has complex life cycle but involves two host, a vertebrate host (Humans); and an invertebrate host (mosquito). Sporozoites of parasite transmitted by bite of female Anopheles mosquito (that has bitten someone with malaria at a particular stage). [5] When this…
