“…oocyst faecal count was also observed previously in other mammalian species (Faber et al, 2002;Taylor et al, 2007;Bruhn et al, 2011;Turner et al, 2012). Moreover, the periparturient increase in the emission of (oo)cysts was also reported for other intestinal protozoa, such as Cryptosporidium parvum and Giardia duodenalis in infected sheep and goats (Xiao et al, 1994;Ortega-Mora et al, 1999;Castro-Hermida et al, 2005).…”

Oocyst excretion pattern of three intestinal Eimeria species in female rabbits

The dynamic change in faecal Eimeria oocyst excretion was evaluated in 10 naturally infected female rabbits, starting from their weaning at 33 d of age until about 1 mo after their second parturition. Faecal samples collected from examined animals were quali-quantitatively analysed to evaluate presence and number of Eimeria oocysts. In addition, isolated Eimeria oocysts were identified at the species level following sporulation. Animals were found to be infected by Eimeria perforans, Eimeria exigua and Eimeria magna and shed Eimeria oocysts after weaning and after parturition. In particular, at 33 d of age all female rabbits examined were negative, while the discharge of Eimeria oocysts started at 39 th day of age and peaked between 46 th and 53 rd day of age. From 81-109 d of age until the first parturition and from 25 d of age of the litters born at the first parturition to the second parturition, all animals resulted negative. After parturition, Eimeria oocyst output occurred from 6 th to 12 th day after the first parturition and from 7 th to 13 th day after the second parturition, while a second period of oocyst excretion was observed from 18 th to 24 th day after both parturitions. These findings may indicate the existence of a relationship between the periparturient phase and Eimeria oocyst output and suggest an important role of the mothers in transmission of the infection to their litters.

“…However, in the following month, a considerable decrease in OPG count was observed. This fall was probably related to host immunity action against Eimeria, which already exists in calves aged three to seven months, like those in the present study (FABER et al, 2002). The decrease in the animal density in the paddock in July, in relation to June, and the less favorable environmental conditions for sporulation of oocysts, such as the low humidity at this time of the year, may also be related to the observed decline in OPG count, thus causing the observed differences between the months (p < 0.05).…”

“…The cause of this difference may have been an incident in which cows at the peripartum stage accidentally gained access to the paddock where the calves were. Faber et al (2002) suggested that close to the time of calving, the OPG count in feces increases, which may result in contamination of the pasture. Michel et al (1972), in England, reported that oocyst production in naturally infected cows increased during the peripartum period, with greater contamination of pasture during this period.…”

The frequency of species of the genus Eimeria in a dairy herd in the municipality of Boa Esperança, Southern region of the State of Minas Gerais was assessed. From 37 females of the Friesian breed aged three to seven months, 259 feces samples were analyzed between May and September 2008. The examinations to quantify oocysts per gram of feces (OPG) and identify Eimeria species were conducted at the Veterinary Parasitology Laboratory of the Federal University of Lavras. Eleven species of Eimeria were identified, namely: E. bovis (23.2%), E. zuernii (22.6%), E. ellipsoidalis (20.3%), E. cylindrica (14.1%), E. subspherica (5.4%), E. canadensis (3.5%), E. alabamensis (2.4%), E. auburnensis (2.4%), E. pellita (2.1%), E. brasiliensis (2%) and E. bukidnonensis (1.9%). E. bovis, E. zuernii and E. ellipsoidalis were the most frequent and the ones with the highest oocyst shedding over time (p < 0.05). Differences in OPG counts were found between most months studied (p < 0.05). The large number of Eimeria species found, in particular E. bovis and E. zuernii, indicates that Eimeria sp. has significant pathogenic potential in dairy cattle in the South of Minas Gerais.

“…Thus, stress factors like weaning, change of diet, sanitation and overcrowding can increase level of infection [11]. And also previous exposure might have a contribution to the development of certain level immunity of older calves as compared to younger that did not experienced previous exposure [18,19] resulting in more susceptibility to coccidiosis than older calves with immunity from previous exposure.…”

A cross-sectional study was conducted from December 2015 up to April 2016 to determine the prevalence of calf Coccidiosis, identify the associated risk factors and to determine the intensity of infection in selected dairy farms from eight woreda of south Wollo zone, Ethiopia. Fecal samples were randomly collected from nine hundred calves belonging to twenty purposively selected dairy farms and were examined for the presence of the oocysts of Eimeria by floatation technique using concentrated sucrose solution. The study revealed that the overall prevalence of coccidiosis was 24.3%. The risk factors considered were age, breed, production system and hygiene status of the dairy farms. The prevalence of Coccidiosis was higher within calves in poor hygiene dairy farms than caves from better hygiene. There was significant difference (P<0.05) in the prevalence of Coccidiosis between the different age groups with the highest prevalence in age category less than 6 months (31.5%). There was also significant variation (P<0.05) between calf breeds. The highest prevalence of Coccidiosis was recorded in calves with diarrheic faeces (61.5%) than the other calves with soft and normal fecal consistency (P<0.05). Appropriate monitoring and control of the disease is advisable in the study farms.
