Molecular detection and subtype distribution of Blastocystis in farmed pigs in southern China.

Blastocystis is one of the most common causative agents of intestinal diseases, which can cause enteric diseases in animals and humans. However, limited data is available on the prevalence or subtypes of Blastocystis infections in farmed pigs in southern China. In this study, a total of 396 fecal samples were collected from farmed pigs in three provinces in southern China in 2016, and screened for Blastocystis by PCR amplification of the small subunit rRNA (SSU rRNA) gene fragment.

Characterization of Neoschoengastia gallinarum from subtropical China by rDNA and identification of two genotypes based on mitochondrial cox1.

Genetic variations in the 18S ribosomal DNA (18S), 28S ribosomal DNA (28S), second internal transcribed spacer of ribosomal DNA (ITS2), and mitochondrial cytochrome c oxidase subunit 1 (cox1) of Neoschoengastia gallinarum collected from subtropical China were examined. First, a portion of the 18S (p18S), a portion of the 28S (p28S), and the complete ITS2 were separately amplified from individual mites and sequenced. The lengths of the sequences of p18S, p28S, and ITS2 were found to be 1379 bp, 3465~3468 bp, and 200 bp, respectively.

Shenfu injection attenuates lipopolysaccharide-induced myocardial inflammation and apoptosis in rats.

Shenfu injection (SFI), a Chinese medicinal product, shows potent efficacy in treating sepsis. The aim of the present study was to clarify the protective effects of SFI against lipopolysaccharide (LPS)-induced myocardial inflammation and apoptosis. Experiments were carried out in Sprague-Dawley (SD) rats treated with LPS or LPS + SFI, and in H9C2 cardiomyocytes.

Prevalence and genotypes of Enterocytozoon bieneusi in pigs in southern China.

Enterocytozoon bieneusi is one of the most important causative agents of microsporidiosis, causing diarrhoea the symptoms of enteric disease in humans and animals. Although there is some information on the prevalence and genotypes of E. bieneusi in China, there is still a lack of data in pigs in southern China.

Vaccination with Eimeria tenella elongation factor-1α recombinant protein induces protective immunity against E. tenella and E. maxima infections.

Avian coccidiosis is caused by multiple species of the apicomplexan protozoan, Eimeria, and is one of the most economically devastating enteric diseases for the poultry industry worldwide. Host immunity to Eimeria infection, however, is relatively species-specific. The ability to immunize chickens against different species of Eimeria using a single vaccine will have a major beneficial impact on commercial poultry production.

Genetic analysis of Toxocara cati (Nematoda: Ascarididae) from Guangdong province, subtropical China.

Toxocara cati (cat roundworm) is a common parasitic nematode that infects humans and other hosts, causing toxocariasis. Although its significance as a pathogen, the epidemiology, genetics and biology of T. cati remain poorly understand in China.

Immune effects of a precocious line of Eimeria necatrix with different doses and at different immunization times.

This study was designed to assess the immune protective effects of the vaccine strain of a precocious line of Eimeria necatrix with different doses and at different immunization times. The immunizations had a negative effect on weight gains of chickens to a certain degree but could be compensated during the "compensatory growth period" after immunity was established in the chickens. The number of oocysts excreted was positively correlated with the immunization dose.

Observation of the excretion pattern of a precocious line of Eimeria necatrix and the strengthening of immune homogeneity.

The excretion frequencies of cecal and intestinal droppings of Chinese Lingnan yellow chickens were observed for 10 consecutive days. The chickens were then orally inoculated with a precocious line of Eimeria necatrix, and the oocysts present in the cecal and intestinal droppings were separately collected and monitored using the McMaster method. The results showed that the excretion frequency of cecal droppings was significantly lower than that of intestinal droppings, and the oocysts of E.

The complete mitochondrial genome of the dwarf tapeworm Hymenolepis nana--a neglected zoonotic helminth.

Hymenolepis nana, commonly known as the dwarf tapeworm, is one of the most common tapeworms of humans and rodents and can cause hymenolepiasis. Although this zoonotic tapeworm is of socio-economic significance in many countries of the world, its genetics, systematics, epidemiology, and biology are poorly understood. In the present study, we sequenced and characterized the complete mitochondrial (mt) genome of H.

Genetic variability among Hymenolepis nana isolates from different geographical regions in China revealed by sequence analysis of three mitochondrial genes.

Hymenolepis nana is a common tapeworm that parasitizes in the small intestine of rodent animals and humans. The present study examined the sequence diversity of three mitochondrial (mt) genes namely NADH dehydrogenase subunits 5 (nad5), small subunit ribosomal RNA (rrnS), and ATPase subunit 6 (atp6) of H. nana from mice in different geographical regions of China.

Rapid detection and identification of four major Schistosoma species by high-resolution melt (HRM) analysis.

Schistosomiasis, caused by blood flukes belonging to several species of the genus Schistosoma, is a serious and widespread parasitic disease. Accurate and rapid differentiation of these etiological agents of animal and human schistosomiasis to species level can be difficult. We report a real-time PCR assay coupled with a high-resolution melt (HRM) assay targeting a portion of the nuclear 18S rDNA to detect, identify, and distinguish between four major blood fluke species (Schistosoma japonicum, Schistosoma mansoni, Schistosoma haematobium, and Schistosoma mekongi).

A specific indel marker for the Philippines Schistosoma japonicum revealed by analysis of mitochondrial genome sequences.

In the present study, near-complete mitochondrial (mt) genome sequences for Schistosoma japonicum from different regions in the Philippines and Japan were amplified and sequenced. Comparisons among S. japonicum from the Philippines, Japan, and China revealed a geographically based length difference in mt genomes, but the mt genomic organization and gene arrangement were the same.

The full mitochondrial genome sequence of Raillietina tetragona from chicken (Cestoda: Davaineidae).

In the present study, the complete mitochondrial DNA (mtDNA) sequence of Raillietina tetragona was sequenced and its gene contents and genome organizations was compared with that of other tapeworm. The complete mt genome sequence of R. tetragona is 14,444 bp in length.
