Giardia lamblia is highly infectious protozoan parasite capable of causing gastrointestinal illness in both humans and animals. The objective of this study was to determine the prevalence of Giardia lamblia infection in children < 5 years old and calves. Enzyme Linked Immunosorbent Assay (ELISA) has been used for the detection of Giardia lamblia. A total of 266 children and 15 calves diarrheic fecal samples were tested for Giardia lamblia during January 2011 to May 2012. The prevalence of Giardia lamblia infection among children was 3.8% while 13.3% in calves. Giardia lamblia was highest in children between 24 and 60 months of age (8.7%). Giardia lamblia infection was higher in male (4.7%) than in female (2.0%). Male calves (14.3%) have slightly higher prevalence than female calves (12.5%). The highest prevalence (33.3%) of Giardia lamblia infection in calves was between the ages 6 and 9 months. This is the first study to determine the prevalence of Giardia lamblia infection in calves using ELISA method in Bangladesh. A larger scale study is needed for accurate estimates of prevalence of Giardia lamblia to undertake an appropriate control strategy in future.DOI: http://dx.doi.org/10.3329/bjvm.v9i2.13474

Full textAbstract:
Giardia lamblia (also referred to as Giardia intestinalis and Giardia duodenalis) is the most common intestinal parasite in the world, affecting approximately 200 million people annually. Symptoms of Giardia include foul-smelling diarrhea, abdominal cramping, bloating, gas, and nausea. Although usually self-limiting, Giardia can progress to dehydration, malnutrition, and failure to thrive, especially in immunocompromised individuals. Early diagnosis and treatment is imperative to prevent and control infection of Giardia. Infectious Disease Society of America diagnostic guidelines recommend obtaining stool studies to diagnose Giardia; when stool studies are negative but suspicion remains high, duodenal aspirate microscopy is the only alternative diagnostic strategy suggested. We report a patient diagnosed incidentally with Giardia from a duodenal biopsy specimen obtained during a workup for a gastrointestinal bleed. There are limited cases of Giardia diagnosed by duodenal biopsy reported in the literature. We review studies that suggest duodenal biopsy can be a very sensitive strategy for the diagnosis of Giardia.

AbstractThis study describes the in vivo activity of Lactobacillus acidophilus in Giardia lamblia infected BALB/c mice. Experimentally, it was observed that daily administration of lactobacilli 7 days before or in simultaneous inoculation with Giardia trophozoites efficiently reduced G. lamblia infection in mice. More specifically, excretion of Giardia cysts were reduced significantly in probiotic-treated groups, and resolution of infection was observed by day 21 post-inoculation. It was also observed that the lactobacillus count increased tremendously and continuously in faeces of all probiotic-fed mice, and was significantly higher as compared with that in control mice. Histological analysis of microvilli membrane integrity revealed that probiotic administration also protected mice against parasite-induced mucosal damage, whereas Giardia-infected mice had severe villous atrophy, oedema, vacuolation and ileitis. Immunologically, the anti-Giardia serum IgG level was not stimulated significantly by probiotic treatment administered both prior to and simultaneous with Giardia infection, but remained high after the infection peak. Taken together, the data demonstrates the anti-giardial effect of the probiotic in vivo by modulation of the intestinal epithelial cells, inhibiting the colonization of Giardia trophozoites and thereby reducing the severity of Giardia infection.

Helicobacter pylori și Giardia lamblia sunt răspândite în întreaga lume. Helicobacter pylori este un factor favorizant pentru prezența Giardia lamblia în stomac datorită neutralizării pH-ului gastric prin secreția de urează. Prezentăm cazul unui copil în vârstă de 5 ani, cu simptome gastro-intestinale intermitente în antecedentele personale patologice recente, care s-a internat în clinica Pediatrie 1 Târgu Mureș pentru dureri abdominale, grețuri, inapetență și hematemeză. Endoscopia digestivă superioară a evidențiat multiple sufuziuni hemoragice ale mucoasei gastrice, iar examenul histopatologic al mucoasei gastrice antrale a identificat coexistența infecției cu Helicobacter pylori și Giardia lamblia. Evoluția pacientului a fost favorabilă sub terapia de eradicare a infecției cu Helicobacter pylori și tratamentul antiparazitar administrat, endoscopia de control arătând o mucoasă fără modificări vizibile macroscopic, iar reevaluare histopatologică evidențiind modificări regenerative ale mucoasei gastrice. Particularitatea cazului este reprezentată de identificarea prezenței parazitozei cu Giardia lamblia în mucoasa gastrică, mediu fiziologic acid, alcalinizat de ureaza secretată de Helicobacter pylori, asigurând astfel condiții favorabile dezvoltării acestui parazit la un copil în vârstă de 5 ani, dintr-un mediu socio-economic favorabil, cu simptome gastro-intestinale intermitente în antecedentele personale patologice recente.

ABSTRACT Mast cells are important for protective immunity to intestinal helminth infections and as mediators of allergic disease. Their role in protozoan infections is less well described. We have therefore analyzed mast cell responses and parasite control in mice infected with the protozoan Giardia lamblia. We also measured immunoglobulin A (IgA) responses to the parasite, as IgA can have a protective role in this model. c-kitw/wv mice failed to make parasite-specific IgA, mount a mast cell response, or eliminate the infection. Anti-c-kit-treated C57BL/6 mice had normal IgA responses, lacked mast cell responses, had reduced interleukin-6 (IL-6) mRNA in the small intestine, and failed to control the infection within 10 days. IL-9-deficient mice had a significant but reduced mast cell response and still controlled the infection within 2 weeks. Interestingly, IL-6-deficient mice had enhanced mast cell responses yet failed to rapidly control the infection. However, prevention of mast cell responses in IL-6-deficient mice by anti-c-kit treatment did not lead to parasite elimination. Both IL-6- and IL-9-deficient mice had normal IgA production. IL-6-deficient mice had significant serum levels of mast cell mediators, histamine and mast cell protease 1, following infection. Together, these results show that mast cells are important for the rapid control of Giardia infections in mice. Furthermore, they show that IL-6 is not necessary for these mast cell responses. Instead, they suggest that mast cell production of IL-6 appears to be important for control of this infection.

Full textAbstract:
Helicobacter pylori and Giardia lamblia are common worldwide. Helicobacter pylori is a favoring factor for the presence of Giardia lamblia in the stomach due to the neutralization of the gastric pH through the secretion of urease. We present the case of a 5-year-old child, with intermittent gastro-intestinal symptoms in the recent personal pathological history, admitted in the Pediatrics Clinic 1 Târgu Mureș for abdominal pain, nausea, loss of appetite and hematemesis. The superior digestive endoscopy revealed multiple hemorrhagic lesions of the gastric mucosa, and the pathological exam of the antral gastric mucosa identified the coexistence of Helicobacter pylori and Giardia lamblia. The evolution of the patient was favorable under the eradication therapy of the infection with Helicobacter pylori and the antiparasitic drugs, the control endoscopy revealing a gastric mucosa without macroscopically obvious modifications, and the pathological re-evaluation pointed out regenerative modifications of the gastric mucosa. The particularity of the case is represented by the identification of the parasite Giardia lamblia in the gastric mucosa, a physiologically acid environment, alkalinized by the urease secreted by Helicobacter pylori, therefore providing favorable conditions for the development of this parasite in a 5-year-old child, from a favorable socio-economic environment, with intermittent gastrointestinal symptoms in his recent personal pathological history.

ABSTRACTWe have studied immune mechanisms responsible for control of acuteGiardia lambliaandGiardia murisinfections in adult mice. Association of chronicG. lambliainfection with hypogammaglobulinemia and experimental infections of mice withG. murishave led to the hypothesis that antibodies are required to control these infections. We directly tested this hypothesis by infecting B-cell-deficient mice with eitherG. lambliaorG. muris. Both wild-type mice and B-cell-deficient mice eliminated the vast majority of parasites between 1 and 2 weeks postinfection withG. lamblia. G. muriswas also eliminated in both wild-type and B-cell-deficient mice. In contrast, T-cell-deficient andscidmice failed to controlG. lambliainfections, as has been shown previously forG. muris. Treatment of wild-type or B-cell-deficient mice with antibodies to CD4 also prevented elimination ofG. lamblia, confirming a role for T cells in controlling infections. By infecting mice deficient in either αβ- or γδ-T-cell receptor (TCR)-expressing T cells, we show that the αβ-TCR-expressing T cells are required to control parasites but that the γδ-TCR-expressing T cells are not. Finally, infections in mice deficient in production of gamma interferon or interleukin 4 (IL-4) and mice deficient in responding to IL-4 and IL-13 revealed that neither the Th1 nor the Th2 subset is absolutely required for protection fromG. lamblia. We conclude that a T-cell-dependent mechanism is essential for controlling acuteGiardiainfections and that this mechanism is independent of antibody and B cells.

ABSTRACT In this study, we investigated the role of interleukin-6 (IL-6) in Giardia lamblia infections in mice. Elevated IL-6 expression was found in wild-type mice 15 days postinfection. Furthermore, IL-6-deficient mice controlled infections only slowly although normal immunoglobulin A production was observed. Thus, IL-6 is necessary for early control of acute G. lamblia infections.

Full textAbstract:
Giardia lamblia is an early branching eukaryote and although distinctly eukaryotic in its cell and molecular biology, transcription in G. lamblia demonstrates important differences from these processes in higher eukaryotes. α-amanitin is a relatively selective inhibitor of eukaryotic RNA Polymerase II (RNAP II), and is commonly used to study RNAP II transcription. Therefore, we measured the sensitivity of G. lamblia RNAP II transcription to α-amanitin and found that unlike most other eukaryotes, RNAP II transcription in Giardia is resistant to 1 mg/ml amanitin. To better understand transcription in G. lamblia, we identified 10 out of the 12 known eukaryotic rph genes, including all ten that are required for viability in Saccharomyces cerevisiae. The amanitin motif (amanitin binding site) of Rpbl from G. lamblia differs from other eukaryotes at six highly conserved sites in which substitutions have been associated with amanitin resistance in other organisms. These observations of amanitin resistance provide a molecular framework for the development of novel drugs with selective activity against G. lamblia. Giardia trophozoites exhibit antigenic variation of a surface protein encoded by a family of genes known as the vsp genes. A single trophozoite expresses only one vsp at a time and it has been previously determined that steady state mRNA of only the expressed vsp is detectable in Northern blots. Our nuclear run-on assays indicated transcription of only the expressed vsp genes, suggesting that control is primarily at the level of transcription rather than post-transcription. In order to better understand vsp gene control mechanisms, we used a luciferase reporter to determine the vsp core promoter, which is present within 100 bp upstream of the ORF in the case of vspCS and vspA6. The fact that the vsp promoter is able to drive expression irrespective of the antigenic variant type indicates that control requires a chromosomal context as do most epigenetic mechanisms of control. Based on the existing data, we provide a privileged site model for the control of vsp gene expression, in which vsp transcription takes place in a set nuclear location which is occupied by a singe vsp locus at a time.

Full textAbstract:
Diarrhea caused by rotavirus and Giardia is a major health problem among children attending day-care centers because of inadequate personnel hygiene. Epidemiological evidence suggesting person-to-person transmission of enteric pathogens has long been recognized. This study was initiated to investigate the effectiveness of handwashing for the removal of rotavirus and Giardia from contaminated hands. The palms of participant hands were innoculated with approximately 103 Giardia cysts or 105 plaque forming units of rotavirus and the effect of washing using tap water alone, a liquid soap or a bar soap on their removal was assessed. Handwashing with liquid soap was found to be very effective in the removal of rotavirus and Giardia cysts as compared to washing with bar soap or tap water alone. The overall recovery of viruses in both bar soap and liquid soap was low (0.03-22.5%), probably due to virus inactivation by the detergent.

Full textAbstract:
Introdução: A Giardia lamblia é um protozoário de característica cosmopolita e zoonótica, vista como um preocupante problema no que diz respeito a saúde pública, estão inseridos especialmente em regiões de clima tropical, porém podem ser detectados em temperaturas diversificadas. Há diversas formas da expressão clínica da giardíase, que pode ser assintomática, aguda ou crônica e tais expressões estão veiculadas à diversos elementos no que diz respeito ao hospedeiro, por exemplo como seu status imunológico, seu estado nutricional, e fatores que se referem ao parasito, como a virulência e a patogenia da cepa. Objetivos: Tem-se por escopo relatar a importância na medicina veterinária, na saúde pública e a relevância no controle da infecção. Material e Métodos: Estruturalmente, Scielo e PubVet foram as bases de dados, acessadas no ano de 2021 e desfrutou-se dos dois e três artigos, respectivamente. Resultados: A infecção por Giardia spp ocorre de forma direta, através de cistos eliminados junto das fezes que sobrevivem durante meses no meio ambiente e por meio dos trofozoítos, que se desenvolvem no intestino delgado através da ingestão de cistos, ocasionando os sinais clínicos da infecção que consistem em diarreia mucoide com odor fétido, desidratação, emagrecimento e má absorção intestinal, assim, o homem, ruminantes e pequenos ruminantes, suínos, equinos, caninos e felinos podem se contaminar. O diagnóstico pode ser clínico ou laboratorial e o tratamento constitui-se a base de fármacos anti-helmínticos. Ressalta-se que é indispensável práticas de boa higiene e prevenção de contaminação nas fezes em água e alimentos, a vermifugação, a higienização dos pelos dos animais e a prevenção através da vacina em cães. Conclusão: De acordo com o que foi supracitado, a proximidade dos animais acometidos principalmente cães e gatos deve ser ponderado, além do mais, o protozoário é uma zoonose e é notório que a giardíase é um problema de saúde pública e deve ser observado.
