“…The most prevalent species of Eimeria found in this study were E. bovis (67.9%), E. ellipsoidalis (39.1%), E. cylindrica (31.8%), and E. zuernii (30.3%) in cattle. These species were widespread also in other countries ( 8 , 12 , 36 , 43 , 44 ), while some species, such as E. pellita, E. bukidonensis , and E. brasiliensis ( 7 , 8 , 12 , 43 , 44 ), were not found in our study. In water buffaloes, E. ellipsoidalis was the most prevalent (36.3%) species, followed by E. auburnensis (26.7%), E. bovis (22.3%), and E. zuernii (18.2%); in addition, E. bareillyi , the buffalo host-specific species, showed a prevalence of 12.3%.…”

“…The 10-year surveillance program indicates that eimeriosis is common (up to 100%) in cattle and water buffaloes in the Mediterranean area studied as in different parts of the world (5,7,8,11,13,15,35,36). The overall prevalence of Eimeria spp.…”

“…The results of seasonality showed there were no significant differences between the seasons. Some authors found statistically significant differences between seasons and prevalence in animals (1,7,8,35,41,42), but in the Mediterranean area the large ruminant farming system is mainly intensive and so the presence of Eimeria might not be influenced by the weather or by grazing, but rather by overcrowding and herd management (e.g., hygiene of pens).…”

“…More than 20 Eimeria species are described in cattle ( 8 ), and among them, 12 species can affect also water buffaloes ( Bubalus bubalis ) ( 9 , 10 ) although coccidia are usually host-specific parasites. E. zuernii, E. bovis , and E. auburnensis are the most pathogenic species in both hosts worldwide ( 11 , 12 ), while E. bareillyi is a pathogenic species specific only for water buffaloes ( 13 ).…”

Coccidiosis due to Eimeria spp. are widespread parasitic infections in cattle and water buffaloes and may impair health, welfare, and production of these livestock species. The aims of this study were (i) to investigate the prevalence and seasonal dynamics of eimeriosis and (ii) to characterize the Eimeria species in large ruminants in a Mediterranean area, in order to plan effective control strategies. Parasitological data were obtained from a 10-year surveillance program (2010-2019) on 3,631 farms (2,089 buffalo and 1,542 cattle farms) sampled in central and southern Italy. Pooled fecal samples were analyzed using the FLOTAC technique with an analytic sensitivity of 2 oocysts per gram of feces (OPG) utilizing a saturated sodium chloride flotation solution (specific gravity = 1.200). Eimeria species identification was performed by morphometric analysis after a one week incubation of oocysts in a 2.5% potassium dichromate solution. The results showed high prevalence of Eimeria (up to 100%) in both cattle and buffaloes in the 10 years of surveillance, even if a slight reduction was reported in the last three years. The overall prevalence of eimeriosis was 91.7% (95% confidence interval, 95% CI = 90.2-93.1) in cattle farms and 81.5% (95% CI = 79.8-83.1) in water buffalo farms. The mean OPG value was 66.8 (min = 2; max = 8,065) in cattle and 55.9 (min = 2; max = 15,415) in water buffaloes, but this difference was not statistically significant (p > 0.05). In total, nine species of Eimeria were found in cattle the most prevalent being Eimeria bovis, E. ellipsoidalis, E. cylindrica, and E. zuernii, whereas in water buffaloes eight species of Eimeria were found, the most prevalent being E. ellipsoidalis, E. auburnensis, E. bovis, and E. zuernii. Mixed infections were common in both ruminant species. The seasonal pattern showed a higher prevalence of eimeriosis in cattle in spring (86.9%) whereas in buffalo farms the prevalence was higher in winter (82.3%) and summer (82.4%). In conclusion, the 10-year surveillance program indicates that eimeriosis is common in cattle and water buffaloes and therefore continuous effective control strategies are needed.

A pilot study for the isolation of Eimeria spp. oocysts from environmental straw samples in comparison with individual faecal examination of fattening calves

et al. 2023

The diagnosis of eimeriosis in calves mainly relies on the presence of diarrhoea and the excretion of Eimeria oocysts in the faeces. Restraining the animals to collect rectal samples for diagnostic purposes is stressful and time-consuming. The aim of this study was to evaluate a method for the quantification of oocysts in environmental barn straw samples. To investigate the recovery rate of the method, straw and Eimeria negative faeces were spiked with Eimeria oocysts in plastic bags and mixed with water and 0.05% Tween 20 (v/v); the liquids were filtered twice through sieves (mesh size 300 and 52 μm), centrifuged and the number of oocysts in the sediment determined using a McMaster counting chamber. A recovery rate of 52.4% (95% confidence interval: 48.2–56.5%) was obtained. In the following, field straw (n = 156) and individual faecal samples (n = 195, also analysed by McMaster counting chambers) were collected on four different farms. Eimeria oocysts were present on all farms in faecal (84/195, 43.1%) and straw samples (119/156, 76.3%). In 37 (23.7%) straw samples, sporulated oocysts were observed, with a sporulation rate ranging from 0 to 40%. Despite high variability between farms and examination days, mean numbers of oocysts in the straw positively correlated with mean numbers of oocysts excreted in the faeces (ρSpearman = 0.60). The examination of environmental straw samples may represent an easy-to-perform, non-invasive, inexpensive preliminary diagnostic approach for surveillance of eimeriosis at group level, having the potential to assess the infection pressure.
