The Predominance of Giardia duodenalis AII sub-assemblage in young children from Salvador, Bahia, Brazil.

CONCLUSIONS: The higher frequency of AII sub-assemblage suggests that anthroponotic transmission is more common in Salvador, but that zoonotic transmission pathways are also present and a change in susceptibility to different molecular patterns of Giardia may occur during child growth.

Abstract To assess the prevalence and molecular characteristics of Cryptosporidium spp., Giardia duodenalis and Enterocytozoon bieneusi in natural grazing local breed cattle, 513 fecal samples from Tibetan yellow cattle and cattle-yaks were tested for these pathogens. Cryptosporidium, G. duodenalis and E. bieneusi in Tibetan yellow cattle prevalence were 0.7% (3/442), 3.8% (17/442) and 2.5% (11/442), respectively. Cryptosporidium bovis (n = 3), G. duodenalis assemblages A (n = 2) and E (n = 15) were identified based on sequence analysis. Among three E. bieneusi genotypes, I (n = 7), EbpC (n = 2...

In this study, frequency of different assemblages ofG. duodenalis was determined in sheep and goats bygdh gene and PCR-RFLP method. Same of other studies, assemblage E was dominant genotype in sheep and goats. Isolation of zoonotic assemblages as AI, AII, and BIII showed that sheep and goats should be considered as a source for human infection.

Authors: Sepahvand A, Hosseini-Safa A, Yousofi HA, Tajedini MH, Pahlavan Gharehbabah R, Pestehchian N Abstract Background: We aimed at genotyping and evaluating the predominance of G. duodenalis assemblages isolated from patients referred to medical laboratories in Khorramabad, Iran from Nov 2015 to Sep 2016. Hence, the development of a cost-effective HRM approach to determine genotypes of G. duodenalis based on the triosephosphate isomerase (tpi) gene was examined and the genotyping results with and without diarrhea was compared. Methods: Seventy G. duodenalis positive fecal samples were collected. A microscop...

Tang, Anai á da Paixao Sevá, Camila Albano dos Santos, Silvia Maria Santos Carvalho, Christiane Maria Barcellos Magalhães da Rocha, Bruno César Miranda Oliveira, George Rego Albuquerque The aim of this study was to determine the prevalence and risk factors of the main enteric parasitic infections that affect children and dogs in the municipality of Ilhéus, Bahia, Brazil; and to identify the geopolitical areas that should receive priority interventions to combat them. Between Mar ch and November 2016, fecal samples of 143 dogs and 193 children aged 1 mont...

This study examines the risk factors associated with pediatric diarrhea and carriage of zoonotic enteric pathogens among children living in communities where smallholder livestock production is prevalent. We conducted an observational study of children younger than 5 years that included the analysis of child (n = 306) and animal (n = 480) fecal samples for Campylobacter spp., atypical enteropathogenic Escherichia coli, Shiga toxin-producing E. coli, Salmonella spp., Yersinia spp., Cryptosporidium parvum, and Giardia lamblia. Among these seven pathogens, Giardia was the most commonly identified pathogen among children and a...

CONCLUSIONS: The results of this study demonstrate the potential risk of infection with Leptospira spp. in veterinarians working with pigs. Veterinarians could be also be at risk of infection with T. gondii and G. duodenalis. PMID: 32208594 [PubMed - in process]

Abstract Giardia duodenalis is a zoonotic enteric parasite that can infect humans and a number of animal species including rabbits with a worldwide distribution. Infection with G. duodenalis can cause serious public health problems and significant economic losses to animal husbandry. So accurate understanding of the prevalence and genotype distribution of G. duodenalis in rabbits is necessary. In the present study, a total of 616 fecal samples were collected from rabbits in Shandong province, eastern China, and examined in G. duodenalis prevalence and genotypes by nested PCR amplification of β-giardin (bg), g...

Authors: Shahnazi M, Naghizadeh F, Hajialilo E, Alizadeh SA, Saraei M, Alipour M Abstract Background: We aimed to investigate the genotypes of Giardia intestinalis among the food handlers in Qazvin, Iran. Methods: Overall, 1530 stool specimens were collected from the food handlers who visited Shahid Bolandian Health Center, Qazvin, Iran during 2016. Specimens were evaluated by microscopic and concentration methods. Twenty specimens with appropriate number of giardia cysts were selected followed by DNA extraction. Determination of giardia genotypes was achieved through PCR and sequencing the glutamate dehydrogen...
