4. Discussion Babesia has a worldwide economic importance due to the enormous losses it causes for the livestock industry. A subunit antigen attracted the attention for the development of anti-Babesia vaccine (Brown et al., 2006). In this respect, HSPs have emerged as prospective immunostimulatory components for vaccine development (Suto and Srivastava, 1995; Suzue and Young, 1996; Zugel and Kaufmann, 1999). Therefore, we investigated the characterization of a member of the HSP-70 family from B. bigemina. The sequence of BbigHSP-70 was found in the genome sequence database of B. bigemina through the blast search with homologue sequences of B. bovis and B. gibsoni. The sequence of BbigHSP-70 from the Argentina strain was identified by sequencing. Gene has 2 copies in most apicomplexan, but we did not analyze the copy number in B. bigemina; this will be done in a future study. Phylogenetic analysis of the amino acid sequence showed that all intraerythrocytic protozoan parasites, including Plasmodium spp., make one group located outside the paraphyletic group containing eumycetes and vertebrates. Since the HSP-70 of the parasites and hosts do not seem to be closely related, they likely evolved separately. The H SP-70 of Babesia, Theileria and Plasmodium seem to be closely related; therefore, the function of HSP-70 might be similar among these parasites. Jie et al. (1996) suggested that HSP-70 perform functions critical to the survival of B. microti parasites. As described
Pests – Pests like flies, ticks, lice, and mosquitos can all cause stress on beef cattle during any stage of life. Pests, like lice, can cause irritation to a cows hide. Lice can cause hair loss and rashes ultimately leaving the animal uncomfortable.
During every year everyone trembles in fear as a new and stronger strand of flu like sickness comes along. These viruses are met with vaccines that are swiftly made by the World Health Organization. The problem with the way that vaccines are made is, the World Health Organization not only makes the vaccines but also deems the vaccines safe. Since they are responsible for making and deeming the vaccines safe, mistakes can lead to mass deaths. For this reason there should be checks and balances where other agencies test the vaccines for potential threat of mental illness, dangerous ingredients, and death. This system is definitely due for an complete overhaul due to the lives of the families that are affected.
using 50 µg of the same antigen emulsified in Freund's incomplete adjuvant (Sigma) at 14-day intervals. Sera were collected 2 weeks after the last booster and checked for specific antibodies by an indirect immunofluorescence assay (IFA). 2.6. SDS-PAGE and Western blotting Proteins in the extracts were size-separated under reducing conditions by
Are vaccinations important and worth the risks? This is an age-old question that many people have asked since the creation of immunizations. Early last century, diseases like whooping cough, measles, and polio affected hundreds of thousands of people, killing thousands every year. According to the CDC, “More than 15,000 Americans died from diphtheria in 1921.” A vaccine was formulated for this disease, and since then there has only been one reported case in 2004. The vaccine for rubella has achieved the same results. The CDC stated that, “An epidemic of rubella (German measles) in 1964-65 infected 12½ million Americans, killed 2,000
Trypanosoma brucei is a parasite that causes the vector-borne parasitic disease Trypanosomiasis; also known as the African sleeping sickness. The Scientific classification of Trypanosoma is as follows: Domain- Eukaryota, Kingdom- Protista, Phylum- Euglenozoa, Class- Kinetoplastea, Order- Trypanosomatida, Family- Trypanosomatidae, Genus- Trypanosoma and Species- T. brucei. The name is derived from the Greek word trypano meaning “borer” and soma meaning “body” because of their cork-screw like motion. It is a unicellular eukaryote with a single flagella that aids in propulsion and motility. T. brucei is generally found in countries south of the Sahara Desert; the sub-Saharan. The tsetse fly is the vector responsible for transmission to the
Babesia, a major pathogen infecting erythrocytes in animals, is transmitted by ticks to vertebrates and results in serious economic losses in the livestock industry worldwide. B. caballi and T. equi are the major cause of equine piroplasmosis all over the world. The clinical signs include malaise, fever, hemolytic anemia, jaundice, and hemoglobinuria (Kuttler, 1988). Babesia microti, a rodent Babesia, infects humans in North America (Kogut et al., 2005). The babesicidal drugs such as diminazene aceturate and imidocarb dipropionate have adverse side effects related to their toxicity (Vial and Gorenflot, 2006). Therefore, the development of new drugs that have a chemotherapeutic effect against babesiosis with low toxicity to the hosts is urgently needed.
Millions of people around the world die because of diseases that have cures, but this can all be changed if there was a better way of administering these cures and vaccines. There are many non-profit organizations, such as, Project C.U,R,E., that go to developing countries and give vaccines or cures to the natives. But there are still millions of people around the world dying because of curable diseases, such as, malaria, tuberculosis, and acute lower respiratory infections. If I was to invent one thing that could change the world for the better it would be genetically engineered mosquitoes that would used to administer cures in developing countries. Imagine a swarm of mosquitoes that could cure malaria by biting a person, the number of lives
Several antigenic and genetic diversity are recognized (Aldous et al., 2003; Alexander, 1997; Kim et al., 2007) using molecular-based techniques for analyzing the genome sizes (Knipe and Hetsley, 2001).
Recurrent incidence of babesiosis among apparently healthy bovines in Egypt, submits the needs for suitably destined prevalence studies with rapid and accurate diagnosis and immediate treatment of infected animals are required to control this disease. The routine epidemiological survey and diagnosis usually based upon microscopical examination of Giemsa stained blood smears. This technique is insufficient for accurate detection and identification of Babesia species during mixed infections and not reliable for detecting the infection in carrier cases or subclinical infections with low parasitemia. Combination of molecular and serological diagnostic tools for the infection provides powerful tools for accurate diagnosis as well as for epidemiological investigations as means of overcoming limitations of microscopical examination. The polymerase chain reaction will be conducted using highly conserved and species specific genes for detecting the parasite DNA in the blood of infected animals based on the B. bigemina rhoptry associated proteins, Apical membrane protein 1 & Internal trancribed spacer and B. bovis Spherical body proteins 4. The serological diagnostic tools, including the indirect fluorescent antibody test, the Indirect enzyme-linked immunosorbent assay, a competitive ELISA will be conducted to detect Babesia antibodies in serum of naturally infected cattle based on Babesia lysate, Cyanogen bromide-activated Sepharose 4B, affinity purified antigen and expressed,
Take a look at the world around you. Whether you are in America or a third world country you are surrounded by some sort of disease. Preventable or not, the cure for many diseases is through vaccinations early on in childhood. Beginning at birth, parents are encouraged to immunize their children to prevent dangerous diseases they may come in to contact with. The new mandated vaccine law, SB277, which “removes all exemptions to vaccinate requirements for school entry” (California, 2015). Parents are outraged that they no longer have the choice as to whether or not they can vaccinate their children. Vaccinations are immediately beneficial to each person’s immunity and those around you. Do you remember the epidemic just recently
Before vaccines were invented, whenever an individual contracted a disease, it would easily spread to the people who were in contact with the individual. Many became carriers of the disease, resulting in an outbreak. No one was immune from the disease, thus making the vast majority a suitable host for the pathogen. In 1796, British physician Edward Jenner created the first vaccination for smallpox by applying matters of fresh cowpox lesions on an infected eight years old’s hand (Riedel 2005). The fundamental principle behind vaccine is by injecting an antigen (usually a killed or weakened bacteria cell) into a host body; the antigen will imitate an infection and attack the host body. However, since the antigen is weakened or dead before being administered, it will not make the body sick. The antigen triggers the immune system to produce T-lymphocytes1, B-lymphocytes2 and antibodies to attack the affected cells, as though the body was infected with a disease. In the future, when the vaccinated individual encounters the disease, his or her immune system will recognize the pathogen and immediately produce the needed antibodies to fight it, preventing the individual from infected (“Understanding How Vaccines Work” 2013).
4. Discussion The present study describes the identification, expression, and immunological characterization of a member of the profilin family from three pathogenic Babesia species. The deduced amino acid sequence of PROFs from B. bigemina and B. microti is similar to those of other known apicomplexan parasites consisting of polypeptide binding and putative PIP2-interaction sites, profilin family domain, and GlcNAc glycosylation sites (Yarovinsky et al., 2005, 2006; Kursula et al., 2008; Kucera et al., 2010; Jenkins et al., 2010). A phylogenetic analysis revealed that PROF of Babesia species was clustered into a clade closely related to the PROF from other piroplasmids (identities 39.9e73.6% and similarities 55.9e80.5%), indicating that PROF of B. bovis, B. bigemina and B. microti possess a function similar to those of piroplasmids’PROF.
There are three types parasites that cause disease and they are Protozoa, Helminths and Arthropods. Protozoa is a parasite within a single-cell organism. Protozoa can multiply by staying inside the host. Protozoa that live in the blood or tissue of humans are transmitted to other human by the bite of mosquito. Helminth is a worm parasite and helminth is caused by schistosomiasis. Anthropods is like an insect which carries parasitic diseases. There are different types of parasites that affect human and they are endoparasites, acanthamoeba, babesiosis, giardia, leishmaniasis and isosporiasis.
Imagine a world where people aren’t dying from preventable diseases, this ideal world is possible with the use of vaccines. Many people think vaccines are bad for you, and that vaccines cause long term illness, birth defects, and mental illnesses; however, these opinions are not backed up with scientific evidence and are faulty generalizations. These arise from false information spread over the internet. In reality, vaccines are much more beneficial than harmful to our bodies. Vaccines are an essential part of maintaining a healthy, happy life, and getting vaccinated is a necessity.
