Prevalence and molecular characterization of Cryptosporidium spp. and Giardia duodenalis in dairy cattle in Ningxia, northwestern China.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundCryptosporidium spp. and Giardia duodenalis are important gastrointestinal protists in humans and animals worldwide. In China, bovine cryptosporidiosis and giardiasis are of increasing concern because cattle are important reservoirs of these parasites, which have become potential threats to public health and to large numbers of cattle in recent years.
resultsA total of 1366 fecal samples from the Ningxia Autonomous Region were examined. The overall infection rates for Cryptosporidium spp. and G. duodenalis were 1.61% and 2.12%, respectively. Cryptosporidium was only detected in preweaned calves and adults older than 2 years, whereas G. duodenalis was only detected in calves aged less than 11 months. Cryptosporidium spp. were characterized with a PCR-restriction fragment length polymorphism analysis and DNA sequence analysis of the small subunit rRNA gene. Three Cryptosporidium species were identified: C. parvum (n = 15) and C. bovis (n = 4) in preweaned calves, and C. andersoni (n = 4) in adults aged over 2 years. A DNA sequence analysis of the gp60 gene suggested that the 15 C. parvum isolates all belonged to subtype IIdA15G1. Twenty-nine G. duodenalis isolates were analyzed by DNA sequencing of the triosephosphate isomerase (tpi) and glutamate dehydrogenase (gdh) genes. Two G. duodenalis assemblages were identified, assemblages E (n = 15) and B (n = 4, one subtype B1 and three subtype B2) in preweaned calves, and assemblage E (n = 10) in 3-11-month-old calves.
conclusionsThe predominance of C. parvum detected in preweaned calves and the first identified subtype IIdA15G1 in dairy cattle, and the dominant G. duodenalis assemblage E in this study differed considerably from those found in Henan, Heilongjiang, and Shannxi Provinces. Our findings further confirm the dominance of C. parvum IId subtypes in China.
