Summary of "Age patterns of Cryptosporidium species and Giardia duodenalis in dairy calves in Egypt."

Little is known of the occurrence and age patterns of species/genotypes and subtypes of Cryptosporidium spp. and Giardia duodenalis in calves in Egypt. In this study, 248 fecal specimens were collected from dairy calves aged 1 day to 6 months on eight farms in three provinces during March 2015 to April 2016. Cryptosporidium spp. were detected and genotyped by using PCR-RFLP analysis of the small subunit rRNA (SSU rRNA) gene, while G. duodenalis was detected and genotyped by using PCR and sequence analyses of the triose phosphate isomerase (tpi), glutamate dehydrogenase (gdh) and β-giardin (bg) genes. The overall infection rates of Cryptosporidium spp. and G. duodenalis were 9.7 and 13.3%, respectively. The highest Cryptosporidium infection rate (26.7%) was in calves of age ≤ 1 month while the highest G. duodenalis infection rate (44.4%) was in calves of 2 months. Three Cryptosporidium spp. were identified, including C. parvum (n = 16), C. bovis (n = 5) and C. ryanae (n = 3), with the former being almost exclusively found in calves of ≤3 months of age and the latter two being only found in calves of over 3 months. Subtyping of C. parvum by PCR-sequence analysis of the 60 kDa glycoprotein gene identified subtypes IIaA15G1R1 (n = 15) and IIaA15G2R1 (n = 1). The G. duodenalis identified included both assemblages E (n = 32) and A (n = 1), with the latter belonging to the anthroponotic subtype A2. These data provide new insights into the genetic diversity and age patterns of Cryptosporidium spp. and G. duodenalis in calves in Egypt.

Medical and Biotech [MESH] Definitions

Chronic endemic respiratory disease of dairy calves and an important component of bovine respiratory disease complex. It primarily affects calves up to six months of age and the etiology is multifactorial. Stress plus a primary viral infection is followed by a secondary bacterial infection. The latter is most commonly associated with PASTEURELLA MULTOCIDA producing a purulent BRONCHOPNEUMONIA. Sometimes present are MANNHEIMIA HAEMOLYTICA; HAEMOPHILUS SOMNUS and mycoplasma species.

A species of gram-negative bacteria causing PNEUMONIA, MYCOPLASMA in calves. Mycoplasma dispar also possibly plays a synergistic role with other BACTERIA and VIRUSES to cause other RESPIRATORY TRACT DISEASES in calves.

A civilization of ancient Northeastern Africa, concentrated along the lower reaches of the Nile River in the area of Egypt. It was active from 3100 B.C. until its conquest by Alexander the Great in 332 B.C.

A species of VARICELLOVIRUS that causes a fatal MENINGOENCEPHALITIS in calves.

A species of parasitic protozoa that infects humans and most domestic mammals. Its oocysts measure five microns in diameter. These organisms exhibit alternating cycles of sexual and asexual reproduction.
