Epidemiology of bovine fascioliasis in the Nile Delta region of Egypt: Its prevalence, evaluation of risk factors, and its economic significance

Abstract

Aim:This study focuses on the risk factors associated with the prevalence of Fasciola affecting cattle population in three provinces belonging to the Nile Delta of Egypt and to estimate the economic losses as a result of fascioliasis.Materials and Methods:From January 2015 to end of December 2015, records of 21 farms (4976 cattle) were analyzed to screen the prevalence of fascioliasis among cattle farms, to identify its associated risk factors and its economic impacts on Nile Delta region of Egypt.Results:The overall prevalence of fascioliasis in the Nile Delta region of Egypt was 9.77%. The prevalence of fascioliasis was found to be statistically significantly associated with age, sex, breed, and type of farms. The highest prevalence was observed in <2 age group (10.91%), and the lowest was >3 age groups (8.35%). In terms of body condition scores, cattle with medium and poor conditions were associated with fascioliasis more than those with good body condition. Besides, cattle raised in organic farms were associated with lower risk of fascioliasis than those in conventional farms. The prevalence of fascioliasis was noted more prominent in districts with moderate temperatures and with relative humidity (>60%). The annual overall costs for fascioliasis were estimated to be 221.2 USD/cow due to the significant reduction in body weight, reduction in milk production, and the treatment costs for fascioliasis.Conclusion:The results provided could be helpful for improving the control and preventive strategies.

Epidemiological and ultrasonographic investigation of bovine fascioliasis in smallholder production system in Eastern Nile Delta of Egypt

“…This study was conducted in the eastern region of Nile Delta of Egypt, where the majority of the farmers use Nile River's water for irrigation of their land and drinking purpose of their animals. That's why; ruminant animals in such areas are at high risk of liver flukes endemicity (Haseeb et al, 2002;El-Tahawy et al, 2017). high prevalence could argue the remarkably high prevalence of human fascioliasis in Egypt (Haseeb et al, 2002)…”

“…The annual overall costs due to fascioliasis in Egypt is 221 USD per cow due to reduction in body weight, reduction in milk production, and treatment costs (El-Tahawy et al, 2017).…”

Genotyping study of Fasciola gigantica isolated from cattle in Aqrah city, Iraq

“…On the other hand, sequence alignment and phylogenetic tree analysis (Figure 3) reveal complete matching of this study isolates with international records, subsequently, there was no any type of mutations or polymorphisms (as SNPs). This result may be due to that cattle infected mainly by F. gigantica only, in contrast to other ruminants, like sheep, which can infected by F. hepatica and/or F. gigantica, then increasing the possibility of hybridization and cross-mating inside host body, and the following offspring have midway external characters with diverse polidies (4,5,25). The key restraint of this article results is due to F. gigantica isolated from the liver of cattle only in Aqrah city in Kurdistan region of Iraq, thus, in the future it must consider various hosts in different regions of the country.…”

Trematodoses in Cattle and Buffalo Around Schistosomiasis Endemic Areas in Central Sulawesi Province of Indonesia

“…Penularan Schistosomiasis, menurut Hu et al (2017) negara lain pun berkisar antara 386% (Islam et al 2016;Karim et al 2015;Khoramian et al 2014;Bedada et al 2017;Elkhatam & Khalafalla 2016;El-Tahawy et al 2017;Elshraway & Mahmoud 2017;Hussein & Khalifa 2010;Hassan et al 2017;Elliott et al 2015;Pandya et al 2015;Yadav et al 2015). Infeksi oleh Fasciola gigantica pada sapi dan kerbau di Indonesia pada studi ini dapat terjadi berkaitan dengan kondisi iklim yang memungkinkan perkembangbiakan inang antaranya, yakni keong Lymnea rubiginosa (Widjajanti 2004).…”

“…Hal ini juga dapat menjadi penyebab tingginya prevalensi trematodosis pada penelitian ini. Hewan yang tidak menerima antihelmintika dapat memiliki risiko tinggi menderita trematodosis (El-Tahawy et al 2017;Kheider 2014).…”
