Book Description
Giardiasis is still a significant infectious and parasitic disease, caused by the protozoan Giardia intestinalis. There are estimates of more than 200 million cases of giardiasis occurred in the world annually. The advance in research in giardiasis during the last century and particularly during the last decade is considerable. Nevertheless, many challenges still are ahead in order to reach a higher control of this disease. This book tried to update the significant epidemiological and clinical research in many aspects with a multinational perspective. This book with 9 chapters has been organized in 3 major sections: 1. "Overview, Epidemiology and Clinical Aspects," 2. "Biological and Diagnostic Aspects," and 3. "Treatment, Prevention and Public Health."

Book Description
Giardia is a relatively simple eukaryotic microbe, causing acute and chronic diarrhea which has been used as a model to understand complex biological processes occurring in eukaryotic cells. Further, due to its parasitic lifestyle, Giardia is an excellent system for the study of the mechanisms of adaptation and cell differentiation from the perspectives of molecular and cell biology. This book presents a comprehensive review of the current state of knowledge regarding all aspects of Giardia’s biology, including epidemiology, cell and molecular biology, genetics, pathogenesis, diagnostics, and clinical treatment. It was written by internationally renowned authors, the leading researchers in the field including several chapters with techniques and resources available for the study of this microorganism. Questions that need to be addressed to fully understand the molecular mechanisms of the parasite as well as the cause of its pathology are presented. Furthermore, Giardia’s biology is compared with that of other parasites in relation to their complexity. This volume is an indispensable resource for researchers working with this parasite. It is a “must” for libraries and the bookshelves of everyone interested in the biology of parasites and early-branching eukaryotes.

Book Description
One of the top four contributors to the global burden of disease is diarrheal infections. Intestinal parasites are major causes of morbidity and mortality associated with diarrheal diseases in both the developed and developing world. Amebiasis is responsible for 50 million cases of invasive disease and 70,000 deaths annually in the world. Giardiasis has an estimated worldwide prevalence of 280 million cases annually. In developed countries, Giardia lamblia infects about 2% of adults and 6-8% of children. The prevalence of G. lamblia infection is generally higher in developing countries, ranging from 3% to 90%. Furthermore, giardial infections contribute substantially to the 2.5 million annual deaths from diarrheal disease. In Asia, Africa, and Latin America, about 500,000 new giardiasis cases are reported each year. Cryptosporidium accounts for 20% and 9% of diarrheal episodes in children in developing and developed countries, respectively. Infection with Cryptosporidium can be chronic and especially debilitating in immunosuppressed individuals and malnourished children. A recent study to measure disease burden, based on disability-adjusted life years (DALYs), found that cryptosporidiosis and amebiasis produce about 10.6 million DALYs. This exceeds the DALYs of any helminth infection currently being targeted by the World Health Organization for preventive chemotherapy. Because of its link with poverty, Giardia and Cryptosporidium were included in the WHO Neglected Diseases Initiative in 2004. E. histolytica, G. lamblia, and C. parvum have been listed by the National Institutes of Health (NIH) as category B priority biodefense pathogens due to low infectious dose and potential for dissemination through compromised food and water supplies in the United States. Despite the prevalence of amebiasis, giardiasis, and cryptosporidiosis there are no vaccines or prophylactic drugs. The first-line drugs for invasive amebiasis and giardiasis chemotherapy are nitroimidazoles, with the prototype, metronidazole, being the most common drug used worldwide. Metronidazole has been shown to be both mutagenic in a microbiological system and carcinogenic to rodents, and frequently causes gastrointestinal side effects. In spite of the efficacy of nitroimidazole drugs, treatment failures in giardiasis occur in up to 20% of cases. Clinical resistance of G. lamblia to metronidazole is proven and cross resistance is a concern with all commonly used antigiardial drugs. Nitazoxanide, the only FDA-approved drug for the treatment of cryptosporidiosis, is effective in the treatment of immunocompetent patients and partially effective for immunosuppressed patients. Therefore, it is critical to search for more effective drugs to treat amebiasis, giardiasis, and cryptosporidiosis. This Research Topic for Frontiers in Microbiology will explore the recent progress in drug development for parasitic diarrheal diseases. This includes an understanding of drug resistance mechanisms. We would also welcome submissions on the drug development for other diarrheal parasites. We hope that this research topic will include a comprehensive survey of various attempts by the parasitology research community to create effective drugs for these diseases.

Book Description
Neglected tropical diseases (NTDs) is a diverse group of communicable diseases that prevail in tropical and subtropical conditions in 149 countries. NTDs affect more than one billion people and cost developing economies billions of dollars every year. According to the World Health Organization (WHO), NTDs mainly affect populations living in poverty, without adequate sanitation, and in close contact with infectious vectors, domestic animals, and livestock. Migration, as well as climate change and variability, are key factors in NTD prevalence. Therefore, NTDs deserve more study. Recently, viruses transmitted by vectors (arboviruses) that affect not only people living in the tropics, but also travelers and migrating populations, have been causing epidemics. Examples of these viruses include Dengue, Chikungunya, Zika, Mayaro, and encephalitis viruses. These viruses emerge and reemerge in multiple regions of the world, as occurred in the Americas recently (2013-2017) with Chikungunya and Zika. This book aims to update the significant epidemiological and clinical research of NTDs in many aspects with a multinational perspective.

Book Description
The enteric protozoans Cryptosporidium spp. and Giardia duodenalis are the most common diarrhoea-causing protozoan parasites worldwide. Cryptosporidium spp. is a leading cause of diarrhoea morbidity and mortality in children younger than 5 years of age in poor-resource settings in sub-Saharan Africa and South Asia. Although infection by G. duodenalis is rarely a fatal condition, giardiasis is commonly associated with childhood growth faltering and cognitive impairment. Because of their significant socioeconomic impact, particularly in low-income countries, giardiasis and cryptosporidiosis joined the "Neglected Disease Initiative" launched by the World Health Organization in 2004. Both Cryptosporidium spp. and G. duodenalis are ubiquitous in the environment and can infect a wide range of hosts with different specificities, meaning that humans may acquire the infection via waterborne, foodborne, or zoonotic transmission. Recent advances in detection and molecular epidemiology have indicated that certain species/genotypes of Cryptosporidium and G. duodenalis have an expanded range of suitable hosts, suggesting that their transmission pathways are more intricate than previously thought, challenging our current notion of host specificities. Therefore, there is a clear need for more studies aiming at investigatingthat aim to investigate the frequency and molecular diversity of these parasites in humans, production and companion animals, and wildlife species. This information would be extremely useful to elucidate the transmission dynamics of cryptosporidiosis and giardiasis, and to investigate the exact contribution of zoonotic events to human infections.
