Vet World 2023; 16:650-656. [PMID: 37041842 PMCID: PMC10082738 DOI: 10.14202/vetworld.2023.650-656] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/18/2022] [Accepted: 02/09/2023] [Indexed: 03/30/2023] Open
Abstract
Background and Aim: In several countries, two Entamoeba porcine species, Entamoeba suis and Entamoeba polecki (subtype 1 and 3), have been detected using molecular methods and identified pathogenicity associated with enteritis. However, globally, Entamoeba infection prevalence in pigs is extremely limited. This study aimed to coprologically and genetically examine pig parasites to estimate prevalence of Entamoeba in three pig farms in East Java, Indonesia.
Materials and Methods: Hundred porcine fecal samples (Landrace) were collected from three East Javan farms in well-known swine industry regions. Fecal samples were examined under microscope after sugar-flotation centrifugation, and molecular species and subtype identification were performed using polymerase chain reaction (PCR) and primer pairs targeting small-subunit ribosomal RNA.
Results: Microscopy examinations identified parasites in 89/100 fecal samples; Entamoeba spp. cysts were the most frequent in these samples. Polymerase chain reaction showed that 58 samples were comprised of mixed Entamoeba suis and Entamoeba polecki, 22 E. suis alone, and nine E. polecki alone infections. Epolec F6–Epolec R6 primers successfully amplified E. polecki ST1–4 subtypes, while Epolecki 1–Epolecki 2 amplified only the E. polecki ST1 subtype. Entamoeba polecki ST1-specific primers successfully detected the ST1 subtype in 19/67 E. polecki positive samples.
Conclusion: Entamoeba spp. prevalence in Indonesian pigs was previously shown to be high. On coprological examination of East Javan pigs, we detected high Entamoeba spp. levels, in which we genetically identified as E. suis (80.0%), E. polecki (67.0%), and E. polecki ST1 (19%).
Keywords: East Java, Entamoeba, Indonesia, pig, polymerase chain reaction, small-subunit ribosomal rRNA.

Abstract
BACKGROUND Protozoans of Entamoeba spp. are one of the most common enteric parasites that infect humans and diverse animals including deer. PURPOSE However, data regarding the prevalence and species/genotypes of Entamoeba spp. in deer in China is scarce. This study investigated the prevalence and species distribution of Entamoeba spp. in sika deer (Cervus nippon) in Anhui Province. METHODS In our survey, 336 fecal samples were collected from five sika deer farms in different regions of Anhui Province. All samples were examined for the presence of Entamoeba spp. by PCR and phylogenetic analysis of the conserved 18S rRNA gene. RESULTS 106/336 (31.5%) fecal samples were positive for Entamoeba spp. A statistically significant difference in the prevalence of Entamoeba spp. infection was observed between sampling farms (p < 0.001), and the prevalence of Entamoeba spp. in male and female sika deer showed no significant difference (p > 0.05). Sequence and phylogenetic analysis revealed the single species, E. bovis, was identified in this study. CONCLUSION This is the first report about the identification of E. bovis in farm-raised sika deer in China, and these results expand our understanding of host range and species distribution of Entamoeba spp. in ruminants.

Abstract
Entamoeba spp. is a common zoonotic intestinal protozoan that can parasitize most vertebrates, including humans and pigs, causing severe intestinal diseases and posing a serious threat to public health. However, the available data on Entamoeba spp. infection in pigs are relatively limited in China. To characterize the infection of Entamoeba spp. within pigs in southern China, 1254 fecal samples of diarrheic pigs were collected from 37 intensive pig farms in Hunan, Jiangxi and Fujian provinces and the infection of Entamoeba spp. was investigated based on the small subunit rRNA (SSU rRNA) gene. The overall infection rate of Entamoeba spp. was 58.4% (732/1254), including 38.4% (118/307) in suckling piglets, 51.2% (153/299) in weaned piglets, 57.9% (55/95) in fattening pigs and 73.4% (406/553) in sows, respectively. Moreover, age and the sampling cities in Jiangxi and Fujian provinces were found to be the key factors influencing the infection of Entamoeba spp. (p < 0.05). Two subtypes (ST1 and ST3) with a zoonotic potential of Entamoeba polecki and Entamoeba suis were detected in all age groups of pigs and all sampling areas, with the predominant species and predominant subtype being E. polecki (91.3%, 668/732) and E. polecki ST1 (573/668), respectively, and E. polecki ST1 + E. polecki ST3 (78.6%, 239/304) being the most frequently detected form of mixed infection. Severe Entamoeba spp. infection and zoonotic subtypes were found in this study, exposing a large public health problem in the study area, and strategies need to be implemented to eliminate the risk in the future.

Abstract
BACKGROUND Pleuropulmonary amoebiasis caused by complications of amoebic liver abscess (ALA) is rare. CASE PRESENTATION A 23 years old male, presented with shortness of breath, cough with yellowish phlegm, right chest pain, fever, bulging stomach, yellow eyes, and swelling of both legs. Abdominal ultrasound and CT scan thorax and abdomen revealed right fluidopneumothorax and liver abscess. Serological testing leads to Entamoeba histolytica infection, which was treated with metronidazole but no significant improvement on empyema and abscess liver size. Surgery was performed after percutaneous aspiration drainage failed to evacuate the abscess. HE and PAS staining from surgical tissue showed Entamoeba hystolitica infection. DISCUSSION Serological testing and radiological examination will be more useful in the early detection of cases of Entamoeba hystolitica infection. Surgery may be considered when purulent drainage does not show improvement in the patient's condition. CONCLUSION ALA complication that causes pulmonary empyema can be surgically treated if the pus cannot be drained.

Parasitic Intestinal Protists of Zoonotic Relevance Detected in Pigs by Metabarcoding and Real-Time PCR. Microorganisms 2021; 9:microorganisms9061189. [PMID: 34073014 PMCID: PMC8229027 DOI: 10.3390/microorganisms9061189] [Citation(s) in RCA: 9] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/11/2021] [Revised: 05/26/2021] [Accepted: 05/27/2021] [Indexed: 11/16/2022] Open
Abstract
Several parasite species are shared between humans and pigs. We explored the application of next-generation sequencing-based metabarcoding supplemented with real-time PCR to fecal DNAs from 259 samples from 116 pigs in Denmark to detect and differentiate single-celled intestinal parasites of zoonotic relevance. Enterocytozoon bieneusi, Balantioides coli, and Giardia duodenalis were observed in 34/37 (92%), 148/259 (57%), and 86/259 (33%) samples, respectively. Entamoeba polecki ST1, E. polecki ST3, and Entamoeba hartmanni were detected in 104/259 (40%), 161/259 (62%), and 8/259 (3%) samples, respectively. Metabarcoding and real-time PCR detected Cryptosporidium in 90/259 (35%) and 239/259 (92%) of the samples, respectively, with Cryptosporidium suis and Cryptosporidium scrofarum observed in nearly equal proportions. Blastocystis subtypes 1, 3, 5, and 15 were found in 72 (28%), 6 (2%), 176 (68%), and 36 (14%) of 259 samples, respectively. Iodamoeba was identified in 1/259 samples (<1%), while none of 37 tested samples was positive for Dientamoeba fragilis. Our results illustrate how metabarcoding exemplifies a 'one-fits-many' approach to detecting intestinal single-celled parasites in feces supplemented with real-time PCR for selected parasites. Using metabarcoding with pathogen-specific assays may help detect emerging and previously underdetected pathogens and further elucidate the role of micro-eukaryotic parasites in human and animal health and disease.
