Abstract
Purpose
Cryptosporidium spp. and Giardia duodenalis are zoonotic protozoan parasites that are widely seen in domestic and wild animals worldwide. While these pathogens, which affect the digestive system of the hosts, cause high economic losses in animal breeding, they are also considered an important public health problem. In recent years, molecular-based studies revealed that 120 genotypes belonging to 44 Cryptosporidium species and eight G. duodenalis assemblages (G. duodenalis A–H) circulate among hosts. The aim of the study was to determine the presence and prevalence of cryptosporidiosis and giardiosis in buffaloes, for which there was only one previous study on the subject in Türkiye.
Methods
In this study, Cryptosporidium spp. and Giardia duodenalis were researched in water buffaloes using polymerase chain reaction (PCR) and DNA sequencing. A total of 510 water buffalo stool samples were obtained from Sivas province, an important water buffalo breeding center in Türkiye.
Results
Cryptosporidium spp. were detected in 20 samples (3.92%), whereas five samples (0.98%) were found to be infected with G. duodenalis. DNA sequence analyses of 18S rRNA and β-giardin genes revealed that five Cryptosporidium species, C. occultus (n = 1), C. andersoni (n = 1), C. ryanae (n = 16), C. parvum (n = 1), and C. bovis (n = 1), and G. duodenalis assemblages E were circulated in water buffaloes in Türkiye, respectively. In this work, C. ryanae was the most prevalent Cryptosporidium species, and DNA sequence analyses of these samples showed that 100% nucleotide identities were present between them. Cryptosporidium occultus (PP754270), C. andersoni (PP754271), C. ryanae (PP754272–PP754279, PP754281–PP754285, PP754287–PP754289), C. parvum (PP754280), and C. bovis (PP754286) obtained from water buffaloes in this study shared 98.59–100%, 99.88–100%, 99.49–100%, 99.62–100%, and 99.87–100% nucleotide similarity with isolates present in GeneBank, respectively. In addition, G. duodenalis (PP798352–PP798356) isolates had 99.56–100% (β-giardin) nucleotide identities with G. duodenalis isolates.
Conclusion
The existence of cryptosporidiosis (the five species) in water buffaloes was reported for the first time in the country. Moreover, one species (C. occultus) has been reported for the first time in Türkiye.
期刊介绍:
Acta Parasitologica is an international journal covering the latest advances in the subject.
Acta Parasitologica publishes original papers on all aspects of parasitology and host-parasite relationships, including the latest discoveries in biochemical and molecular biology of parasites, their physiology, morphology, taxonomy and ecology, as well as original research papers on immunology, pathology, and epidemiology of parasitic diseases in the context of medical, veterinary and biological sciences. The journal also publishes short research notes, invited review articles, book reviews.
The journal was founded in 1953 as "Acta Parasitologica Polonica" by the Polish Parasitological Society and since 1954 has been published by W. Stefanski Institute of Parasitology of the Polish Academy of Sciences in Warsaw. Since 1992 in has appeared as Acta Parasitologica in four issues per year.
