Abdui Raheem Medical Laboratory Techniques Department, Technical Institute / Kufa Al-Furat Al-Awsat Technical University ABSTRACT The study was carried out for access to the hematological changes in patients infected with Giardia lamblia which were performed on 60 blood samples from patients infected with Giardia lamblia and 30 samples of healthy persons. The Samples were collected from patients who attended governmental hospitals: Al-Sadder Medical City, Al-Hakeem General Hospital and Al-Zahra’a Educational Hospital for Child Birth and Children for the period from November 2018 to February 2019. The following tests were performed: Mean corpuscular hemoglobin concentration (MCHC), Mean corpuscular hemoglobin (MCH), Mean corpuscular volume (MCV), Packed cell volume (PCV), Hemoglobin (Hb), Red blood cells (RBCs), White blood cells (WBCs), and platelets (PLTs). The results showed a significant increase (P >0.05) in the number of white blood cells and platelets in patients infected with Giardia lamblia in comparison with control. There was a significant decrease (P >0.05) in the PCV, MCH, MCHC, MCV, and RBCs in patients infected with Giardia Lamblia in comparison with control. Key words: Giardiasis, PCV, MCH, MCHC, MCV and RBCs. Introduction The intestinal parasites infection is one of the most widely known type of parasitic infection among the world (1). Since these parasites and their larval stage can be easily transmitted by contaminated food and water or by direct contact and the carelessness of the vendors of vegetables to clean the vegetables and the contamination of their hands especially in the course of transport and sale have an important role in the infections (2) and if these vegetables were irrigated with untreated sewage (3). Giardia lamblia is one of the most widely known parasites which infect humans and other mammals and the most common causative agent for diarrhea in the world (4)(5). Its incidence is 20-40% in the developing countries (6). The parasite has two phases, cyst and trophozoite (7). Giardia lamblia mainly infects mammals such as humans, cats, dogs and cows (8). The parasite is released from the cyst because of gastric acidity and gastric enzymes (9). The trophozoite attaches itself to the surface of the intestinal epithelium by the ventral sucking disk and then reproduces by binary fission (10). The factors contributing to the presence of clinical features vary depending on the virulence of the parasite strains, numbers of cysts, age of the host and the status of the immune system through infection (11). Some patients with giardiasis has subnormal values of certain blood parameters due to absorption of vitamin B12 (12). The study aims to investigate some hematological profiles in patients infected with giardiasis. 04 Al-Kufa University Journal for Biology / VOL.12 / NO.1 / Year: 2020 Print ISSN: 2073-8854 Online ISSN: 2311-6544 Materials and Methods Sixty samples of feces were collected from patients of different ages. General stool examination, using light microscope (Olympus, CH: Japan) examination was applied for fresh feces obtained from patients complaining from abdominal discomfort and diarrhea, attending to Al-Sadder Medical City Al-Hakeem General Hospital and Al- Zahra’a Teaching Hospital between November, 2018 to February, 2019. Blood samples in EDTA tubes were mixed well in a mixture apparatus and then 0.2 ml of blood from each sample was aspirated by the detector (Sysmex, XP 300 Japan). When the assay was completed, the results were analyzed automatically by the computer and displayed on the monitor and printed, to estimate WBCs count, RBCs, PCV, Hb., MCHC, MCH and MCV. Thirty blood samples were collected from patients from primary health centers with no history of infection with giardiasis and who were apparently healthy by physical examination.

Discussion Giardia lamblia is one of the intestinal parasites that live in the small intestines of humans causing a number of changes including physiological and hematological changes (13). The results showed a significant decrease in RBCs, Hb and PCV (p<0.05) in patients with giardiasis compared to the control group. These criteria are based on a dense coating flagellates on the intestinal epithelium that damages microvilli and interferes with absorption of fat and other nutrients which probably triggers the onset of disease (14). Some patients had subnormal values of certain parameters, particularly serum vitamin B12 and vitamin B12 absorption, fat, and D- xylose. Giardiasis infection is marked by the hypoproteinema with hypogammaglobulinemia, folic acid and fat-soluble architecture of intestinal villi (15). In children giardiasis may be associated with and contribute to protein energy malnutrition (16). Malabsorption syndrome with malabsorption of fat, folic acid and D-xylose occur in the severely affected, and those become weak and anemic (17). The 04 Al-Kufa University Journal for Biology / VOL.12 / NO.1 / Year: 2020 Print ISSN: 2073-8854 Online ISSN: 2311-6544 study has also showed a decrease in the concentration of MCV, MCH and MCHC. The reason is that these criteria are based on RBCs, concentration of Hb. and PCV. The number of platelets showed a significant increase (P<0.05) in patients with giardiasis. Platelets play an important role in mechanical defense against microorganisms, including parasites especially Giardia lambelia which cause an increase in platelets (18).

  • Giardiasis Importance Giardiasis, a Gastrointestinal Disease Characterized by Acute Or Chronic Diarrhea, Is Caused by Protozoan Parasites in the Genus Giardia
    Giardiasis Importance Giardiasis, a gastrointestinal disease characterized by acute or chronic diarrhea, is caused by protozoan parasites in the genus Giardia. Giardia duodenalis is the major Giardia Enteritis, species found in mammals, and the only species known to cause illness in humans. This Lambliasis, organism is carried in the intestinal tract of many animals and people, with clinical signs Beaver Fever developing in some individuals, but many others remaining asymptomatic. In addition to diarrhea, the presence of G. duodenalis can result in malabsorption; some studies have implicated this organism in decreased growth in some infected children and Last Updated: December 2012 possibly decreased productivity in young livestock. Outbreaks are occasionally reported in people, as the result of mass exposure to contaminated water or food, or direct contact with infected individuals (e.g., in child care centers). People are considered to be the most important reservoir hosts for human giardiasis. The predominant genetic types of G. duodenalis usually differ in humans and domesticated animals (livestock and pets), and zoonotic transmission is currently thought to be of minor significance in causing human illness. Nevertheless, there is evidence that certain isolates may sometimes be shared, and some genetic types of G. duodenalis (assemblages A and B) should be considered potentially zoonotic. Etiology The protozoan genus Giardia (Family Giardiidae, order Giardiida) contains at least six species that infect animals and/or humans. In most mammals, giardiasis is caused by Giardia duodenalis, which is also called G. intestinalis. Both names are in current use, although the validity of the name G. intestinalis depends on the interpretation of the International Code of Zoological Nomenclature.

Giardia intestinalis, a protozoan parasite infecting large number of people around the world each year, has been eluding the use of CRISPR/Cas9 technique so far which may be caused by its rather complicated genome containing four copies of each gene in its two nuclei. Apart from only single exception (Ebneter et al., 2016), without the use of CRISPR/Cas9 technology in its full potential, researchers in the field have not been able to establish knock-out cell lines to study the functional aspect of Giardia genes. In this work, we show the ability of in-vitro developed CRISPR/Cas9 components to successfully edit the genome of G. intestinalis. Moreover, we used ‘self-propagating’ CRISPR/Cas9 system to establish full knock-out cell lines for mem, cwp1 and mlf1 genes. We also show that the system function even for essential genes, as we knocked-down tom40, lowering the amount of Tom40 protein by more than 90%.

  • The Intestinal Protozoa
    The Intestinal Protozoa A. Introduction 1. The Phylum Protozoa is classified into four major subdivisions according to the methods of locomotion and reproduction. a. The amoebae (Superclass Sarcodina, Class Rhizopodea move by means of pseudopodia and reproduce exclusively by asexual binary division. b. The flagellates (Superclass Mastigophora, Class Zoomasitgophorea) typically move by long, whiplike flagella and reproduce by binary fission. c. The ciliates (Subphylum Ciliophora, Class Ciliata) are propelled by rows of cilia that beat with a synchronized wavelike motion. d. The sporozoans (Subphylum Sporozoa) lack specialized organelles of motility but have a unique type of life cycle, alternating between sexual and asexual reproductive cycles (alternation of generations). e. Number of species - there are about 45,000 protozoan species; around 8000 are parasitic, and around 25 species are important to humans. 2. Diagnosis - must learn to differentiate between the harmless and the medically important. This is most often based upon the morphology of respective organisms. 3. Transmission - mostly person-to-person, via fecal-oral route; fecally contaminated food or water important (organisms remain viable for around 30 days in cool moist environment with few bacteria; other means of transmission include sexual, insects, animals (zoonoses). B. Structures 1. trophozoite - the motile vegetative stage; multiplies via binary fission; colonizes host. 2. cyst - the inactive, non-motile, infective stage; survives the environment due to the presence of a cyst wall. 3. nuclear structure - important in the identification of organisms and species differentiation. 4. diagnostic features a. size - helpful in identifying organisms; must have calibrated objectives on the microscope in order to measure accurately.

Evolutionary studies have also defined it as a member of one of the earliest diverging eukaryotic lineages that we are able to cultivate and study in the laboratory. Despite early recognition of its striking structure resembling a half pear endowed with eight flagella and a unique ventral disk, a molecular understanding of the cytoskeleton of Giardia has been slow to emerge. Perhaps most importantly, although the association of Giardia with diarrhoeal disease has been known for several hundred years, little is known of the mechanism by which Giardia exacts such a toll on its host. What is clear, however, is that the flagella and disk are essential for parasite motility and attachment to host intestinal epithelial cells. Because peristaltic flow expels intestinal contents, attachment is necessary for parasites to remain in the small intestine and cause diarrhoea, underscoring the essential role of the cytoskeleton in virulence. This review presents current day knowledge of the cytoskeleton, focusing on its role in motility and attachment.

The pathogenic mechanisms are usually unknown and the available reports can be controversial. Methodology: The present study aimed to know, for the first time, the evolution of the hematological profile of the gerbils, experimentally infected with Giardia lamblia, up to the infection’s resolution. Hematological variables have been tested. Results: White blood cells have not presented meaningful alterations during the course of the infection. A significant reduction in the number of red blood cells (p = 0.021), in the concentration of hemoglobin (p = 0.029) and in the value of the hematocrit (p = 0.016) has been observed, starting from the second week of infection, ratifying an anemia related to giardiasis. Reduction in the level of serum iron starting from the third week of infection, despite not being significant, could suggest the participation of iron in the anemia. However, the weight of the animals was kept and the hematimetric parameters started to return to the basic values after the parasitological cure without iron reposition.

  • Chilomastix Mesnili and a Method for Its Culture. by William C
    View metadata, citation and similar papers at core.ac.uk brought to you by CORE provided by PubMed Central CHILOMASTIX MESNILI AND A METHOD FOR ITS CULTURE. BY WILLIAM C. BOECK, I~.D. (From the Deparlment of Medical Zoology of the School of Hygiene and Public Health, the Yohns Hopki~ University, Baltimore.) (Received for publication, July 26, 1920.) In January, 1920, a chronic case of diarrhea due to a flagellate infection was brought to the notice of the author and upon examina- tion the flagellate was identified as Chilomastix mesnilL Attempts to culture this parasitic flagellate proved successful. Observations made from time to time upon the flagellates in both the stools of the patient and the cultures, as well as data derived from a study of permanent preparations, have revealed further information regarding the biology of this organism. It is the purpose of this paper to describe this parasite and its activities and to give a method of culture for the growth of this organism in artificial medium. Regarding its phylogeny, Chilomastix mesnili belongs to the family Tetramitid~e, the order Polymastigina, and the class Mastigophora. The habitat of the parasite is the sm~ll intestine of man. It is often the cause of chronic or intermittent diarrhea. Cases of infec- tion by Chilomastix in man have been reported from nearly every locality in the world. Chalmers and Pekkola1 state that they have always found Chilomastix associated with other protozoa and not entirely by itself. But in the case of infection referred to above Chilomastix was the only protozoan parasite found.

  • Giardia in Dogs
    GIARDIA IN DOGS What are Giardia? Giardia are sometimes confused with “worms” because they invade the gastrointestinal tract and can cause diarrhea. Giardia are one-celled parasites classified as protozoa. Most dogs that are infected with Giardia do not have diarrhea or any other signs of illness. When the eggs (cysts) are found in the stool of a dog without diarrhea, they are generally considered a transient, insignificant finding. However, in puppies and debilitated adult dogs, they may cause severe, watery diarrhea that may be fatal. How did my dog get Giardia? A dog becomes infected with Giardia when it swallows the cyst stage of the parasite. Once inside the dog's intestine, the cyst goes through several stages of maturation. Eventually, the dog is able to pass infective cysts in the stool. These cysts lie in the environment and can infect other dogs. Giardia may also be transmitted through drinking infected water. How is giardiasis diagnosed? Giardiasis or infection with Giardia is diagnosed by performing a microscopic examination of a stool sample. The cysts are quite small and usually require a special floatation medium for detection, so they are not normally found on routine fecal examinations. Occasionally, the parasites may be seen on a direct smear of the feces. A blood test is also available for detection of antigens (cell proteins) of Giardia in the blood. This test is more accurate than the stool exam, but it may require several days to get a result from the laboratory. How is giardiasis treated? The typical drug used to kill Giardia is metronidazole, an antibiotic.
