“…In this study, there was a 6-fold increase in Eimeria spp. infection in ≤ 1 year animals (14.7%, Table 1) compared to >1 year old animals (2.7%); this is consistent with the data of other researchers reporting a strong correlation (P < 0.05) between age groups and infection (Chibunda et al 1997;Abebe et al 2008;Nalbantoglu et al 2008;Almeida et al 2011;Yu et al 2011;Dawid et al 2012;Dong et al 2012;NisarKhan et al 2013). All these results run counter to the study of Abebe et al (2008) who reported that risk of infection by Eimeria species appeared to increase with the age of the examined calves.…”

“…Research performed in other countries has revealed prevalence rates of Eimeria spp. varying from 17.9% to 93% in Poland (Pilarczyk et al 2000;Klockiewicz et al 2007;Pilarczyk et al 2009), 33% in Hungary (Farkas et al 2007), 22.6% and 33.3% in Brazil (Almeida et al 2011;Poscoti-Bruhn et al 2011), 35% to 47.1% in China (Yu et al 2011;Dong et al 2012), 50% in Pakistan (Nisar-Khan et al 2013), 22.7% and 68% in Ethiopia (Abebe et al 2008;Dawid et al 2012), 20%, 68% and 75% in Turkey (Arslan and Tuzer 1998;Cicek et al 2007;Nalbantoglu et al 2008), 29%, 50% and 52% in South Africa (Matjila and Penzhorn 2002), and 35% in Tanzania (Chibunda et al 1997). The rate was reported to be 21.3% and 18% to 50% in the Kurdistan and East-Azerbaijan provinces of Iran (Yakhchali and Gholami 2008;Yakhchali and Zarei 2008;Davoudi et al 2011).…”

Information on the occurrence, diversity and economic losses due to Eimeria infection on cattle farms is lacking in Western Iran. The principal aim of this study was to determine the prevalence and diversity of Eimeria species in cattle in Hamedan province, Western Iran. In a cross-sectional study performed from June 2010 to April 2013, 400 faecal samples were collected randomly from animals without clinical signs from different cattle farms of Hamedan province and examined for Eimeria species infection using parasitology methods. The overall infection rate of Eimeria species was 8.25%. Nine species of Eimeria were identified including: E. bovis (23.7%), E. zuernii (19.2%), E. canadensis (12.6%), E. ellipsodalis (11.4%), E. alabamensis (10.4%), E. pellita (9.1%), E. auburnensis (6.8%), E. cylindrica (4.6%) and E. bukidnonensis (2.3%). There were statistically significant differences with respect to Eimeria infection and age group (P < 0.0001, OR = 6), although no statistically significant relationships were found for sex (P = 0.35) or faecal consistency (P = 0.587). In conclusion, this study is the first to report the prevalence and diversity of Eimeria species in cattle in Hamedan province. Infection with pathogenic Eimeria spp. was asymptomatic in all animals; this is the reason for the transmission of infection by carriers in this region. Therefore, integrated strategies should be utilised to prevent and control Eimeria spp. infection on cattle farms.

“…The adult animals generally suffer from sub-clinical form of disease and act as a source of infection to young and/or newly added stock. A variable prevalence rate of coccidiosis in adult dairy animals has been reported by several workers worldwide, including India (Muraleedharan 2005;Manya et al 2008;Yu et al 2011;Dong et al 2012;Gupta et al 2012;Laha et al 2013). Recent studies from Punjab state reported a prevalence rate of 3.77 % (Singh et al 2012a) and 0.95 % (Singh et al 2012b) from cattle and buffalo populations, respectively.…”

“…The prevalence of coccidiosis in cattle and buffaloes has been well reported from different parts of world (Yu et al 2011;Dong et al 2012) including India (Manya et al 2008;Laha et al 2013) but information regarding prevalence of coccidiosis in cattle and buffalo populations from Punjab state seems to be sporadic Jyoti et al 2011;Singh et al 2012a, b). Moreover, no attempt has been made to determine the species composition of coccidian infection in Punjab.…”

A total of 2089 faecal samples (956 buffaloes and 1133 cattle) were collected from 21 districts of five major agro-climatic zones of Punjab during April, 2013-May, 2014. An overall prevalence rate of 32.17 % (672/ 2089) was recorded for coccidiosis in dairy animals with a significantly higher (P \ 0.01) infection rate in buffaloes (35.46 %) in comparison to cattle (29.39 %). Quantitative analysis revealed oocyst per gram of faeces ranging from 200 to 10,000 (1083.72 ± 227.20) and 100 to 2400 (748.72 ± 81.38), in cattle and buffalo populations, respectively. The results of multivariate analysis showed that prevalence of coccidiosis in cattle population was associated with various risk factors viz. districts (P = 0.000; OR 2.749; 95 % CI 1.238-6.107), agro-climatic zones (P = 0.004; OR 2.707; 95 % CI 1.707-4.293) and seasons (P = 0.000; OR 1.106; 95 % CI 0.811-1.509). Similarly, in buffalo population an association with districts (P = 0.000; OR 2.163; 95 % CI 0.702-6.668), agro-climatic zones (P = 0.000; OR 1.237; 95 % CI 0.673-2.277) and seasons (P = 0.100; OR 1.382; 95 % CI 1.003-1.903) was recorded. The findings of the current study would provide a basis for evolving effective control strategy for the management of coccidiosis in dairy animals of the region.

“…infection in ≤ 1 year animals (36.96%, Table 6) compared to >1 year old animals (11.66%). This general young bias in Eimeria infection is well documented in cattle throughout the world [9,18,36,[39][40][41]. Acquired immunity has been shown to cause a decrease in infection of various Eimeria species with host age [40,42].…”

Subclinical bovine coccidiosis is an economic problem worldwide because they appear normal outwardly, but developmental stages damage the absorptive surface of the intestine and weaken the immune system. Information on the occurrence, diversity and economic losses due to Eimeria infection in cattle is lacking in Al-Baha area. The objective of this work was to study prevalence of subclinical bovine coccidia, throughout Al-Baha area and to evaluate various factors that might potentially influence prevalence and rate of pathogen excretion. A cross sectional study was conducted from July 2014 up to Jun 2015. Out of the total 534 fecal samples examined for Eimeria, 167 (31.27%) were found infected with eight species of Eimeria. Eimeria bovis was found to be the highest frequent species (25.84%), followed in order by E. zuernii (20.78%), E. ellipsoidalis (13.11%), E. canadensis (10.86%), E. alabamensis (8.05%), E. auburnensis (7.78%), E. cylindrica (5.43%), and E. subspherica (2.06%). Young cattle (≤12 month old) had significantly higher infection (P<0.01) of Eimeria. Higher infection of Eimeria was observed in female cattle compared to male ones. Co-infection was commonly present and declined with host age. Positive pair-wise associations were found between Eimeria species. In conclusion, this study was confirm that farm management frequently does not meet the requirements of effective coccidian control and the pathogenic coccidian, E. bovis and E. zuernii are the highest prevalent species in Al-Baha cattle populations. Further epidemiological investigations are required to investigate the different agro-ecological risk factor on the occurrence of bovine coccidiosis.
