Abstract
Cryptosporidium is a genus of single-celled protozoa, infecting a wide range of animals and humans. Although Cryptosporidium infections of cattle have been reported in some provinces in China, there is no available information on the prevalence and predominant species of Cryptosporidium in cattle in Jiangxi province. To investigate the prevalence of Cryptosporidium in cattle in Jiangxi province of China, 556 fecal samples were collected from eight farms in four cities and the SSU rRNA locus of Cryptosporidium was amplified from the DNA of each fecal sample by PCR. The overall prevalence of Cryptosporidium was 12.8% (71/556) in cattle in Jiangxi province, with 24.3% (54/222) in Nanchang city, 7.8% (13/166) in Gao'an city, 3.7% (4/108) in Xinyu city, and 0.0% (0/60) in Ji'an city. The differences of the prevalence rates by region, breed, and age groups were statistically significant. All positive PCR products of Cryptosporidium were successfully sequenced and identified as three Cryptosporidium species, namely Cryptosporidium bovis (1/556, 0.18%), Cryptosporidium ryanae (7/556, 1.3%), and Cryptosporidium andersoni (63/556, 11.3%). Furthermore, 36 C. andersoni isolates were successfully classified into three MLST (multilocus sequence typing) subtypes based on four genetic loci (MS1, MS2, MS3, and MS16). The predominant MLST subtype was A4, A4, A4, A1 (n = 30). These findings not only revealed the prevalence and predominant species of Cryptosporidium in cattle in Jiangxi province, but also provided a baseline for studying the genetic structure of C. andersoni, offering a novel resource for better understanding of the epidemiology of Cryptosporidium infection in cattle in Jiangxi province, southeastern China.

Cryptosporidium Infection Increases the Risk for Chronic Diarrhea Among People Living With HIV in Southeast Asia: A Systematic Review and Meta-Analysis. Asia Pac J Public Health 2020; 32:8-18.

Abstract
We conducted a systematic review research and meta-analysis to reveal the
relationship between the risk of chronic diarrhea and
Cryptosporidium infection in people living with HIV in
Southeast Asia. We performed online peer-reviewed literature research from
January 2005 to December 2017, which included PubMed, Science Direct, ProQuest,
EBSCO, Cochrane, and Web of Science databases. Calculation of size effects in
the meta-analysis was performed by STATA 13.0 software to estimate relative
risks (RRs) with 95% confidence intervals (CIs) for any associations. Seven
cross-sectional research articles were recruited in this study based on the
inclusion and exclusion criteria. Our analysis revealed a significant
relationship between cryptosporidiosis and the risk of chronic diarrhea in
people living with HIV, with RR = 1.325; 95% CI = 1.157 to 1.517; and
P < .000. Our results suggested that cryptosporidiosis
increases the risk of chronic diarrhea, and low CD4+ lymphocyte cell
counts aggravate the degree of diarrhea. Therefore, clinicians should be more
aware in treating HIV-positive people, especially those with low CD4+
cell counts, and we suggest that Cryptosporidium laboratory
examinations be conducted immediately.

Molecular detection and epidemiological risk factors associated with Cryptosporidium infection among cattle in Peninsular Malaysia. Food Waterborne Parasitol 2019; 14:e00035. [PMID: 32095605 PMCID: PMC7033977 DOI: 10.1016/j.fawpar.2019.e00035] [Citation(s) in RCA: 8] [Impact Index Per Article: 1.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/06/2018] [Revised: 01/09/2019] [Accepted: 01/24/2019] [Indexed: 01/06/2023] Open
Abstract
Enteric protozoa infection among cattle may pose a threat to productivity and survival leading to negative impacts on the livestock industry. A number of these pathogens are also known to be zoonotic and are of public health concern. Despite the importance of these enteric protozoa to both animal and human health, there remains a paucity of published information on the epidemiological risk factors that may be associated with bovine cryptosporidiosis in Southeast Asia. The present study was undertaken to determine the molecular prevalence and associated risk factors for Cryptosporidium infection among beef and dairy cattle in Peninsular Malaysia. Faecal samples were collected from 824 cattle in 39 farms (526 beef and 298 dairy) situated in 33 locations throughout the country, and subjected to PCR detection for Cryptosporidium using primers targeting the 18S SSUrRNA gene. Epidemiological variables including host, environment and management factors were subjected to univariate and multivariate logistic regression analyses to determine the potential risk factors for infection. The prevalence of Cryptosporidium among the cattle was 12.5%, with significant difference in the infection rate among the various breeds. There was no significant effect of gender, and both the beef and dairy cattle were at similar odds for infection. The younger cattle had a significantly higher infection rate compared to the older animals. Multivariate analysis revealed that deworming practice, distance to human settlement, geographical location (zone) and farm management system were significant risk factors associated with Cryptosporidium infection. The cattle that were reared on farms located in the northeast of the country, closest (≤200 m) to human settlements, reared extensively, and dewormed every four months were at highest risk of infection. The present study constitutes the first attempt to analyze the multivariable epidemiological risk factors involved in bovine cryptosporidiosis in Malaysia and in Southeast Asia. It is envisaged that the data obtained will facilitate better control and prevention measures for Cryptosporidium infection among cattle in the region. Due to the potential zoonotic nature of the infection, serious steps should be instituted for animal treatment and biohazard waste management on local cattle farms.

Acta Parasitol 2017; 62:772-774. [PMID: 29035847 DOI: 10.1515/ap-2017-0092] [Citation(s) in RCA: 6] [Impact Index Per Article: 0.9] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/14/2017] [Accepted: 08/02/2017] [Indexed: 11/15/2022]
Abstract
Cryptosporidiosis is a common protozoan infection in humans and domestic animals. It is the culprit for significant neonatal morbidity in cattle as well as weight loss and delayed growth, which leads to large economic losses in the farming industry. Furthermore, bovine Cryptosporidium is also a principal source of human Cryptosporidium infections. The purpose of this study is to determine prevalence and genotype of Cryptosporidium spp. from feces of dairy cows from the northern parts of Thailand (Chiang Rai, Chiang Mai, and Lumpang provinces). A total of 500 fecal samples were collected directly from the rectum and they were examined for potential presence of Cryptosporidium infection by using tests such as DMSO-modified acid fast stain, immunofluorescence antibody test (IFAT) and polymerase chain reaction (PCR). The prevalence of Cryptosporidium spp. was 5% by DMSO-modified acid fast stain, 7% by IFAT and 7.6% by PCR respectively. The main genotypes of Cryptosporidium spp. identified were Cryptosporidium parvum and Cryptosporidium bovis. Therefore, as a result of this study, it can be said that, due to the potential cross-species transmission of Cryptosporidium parvum, infected dairy cows may pose a potential zoonotic risk to humans.
