Eimeria infections in goats in Southern Portugal Infeções por Eimeria em caprinos do Sul de Portugal

2014

Coccidiosis caused by Eimeria species is a major form of intestinal infection affecting intensively and semi-intensively reared goats. The province of Alentejo is the main goat-producing area in Portugal. Therefore, all 15 Serpentina goat farms in Alentejo were analyzed regarding the occurrence and diversity of Eimeria species. Fecal samples obtained from 144 animals (52.1% dairy goats, 47.9% pre-pubertal goats) were examined using the modified McMaster technique to determine the number of oocysts per gram of feces. Eimeria spp. oocysts were present in 98.61% of the fecal samples and, overall, nine different Eimeria species were identified. The most prevalent species were E. ninakohlyakimovae (88%) and E. arloingi (85%), followed by E. alijevi (63%) and E. caprovina (63%). The average number of oocysts shed was significantly lower in dairy goats than in pre-adult animals. Astonishingly, no clinical signs of coccidiosis were observed in any of the animals examined, even though they w...

The average number of oocysts shed was significantly lower in dairy goats than in pre-adult animals. Astonishingly, no clinical signs of coccidiosis were observed in any of the animals examined, even though they were shedding high numbers of oocysts and were infected with highly pathogenic species. Thus, implementation of routine diagnostic investigation of the occurrence and diversity of caprine Eimeria species may be a useful tool for determination and better understanding of their potential economic impact on goat herds in southern Portugal.

Prevalence of Eimeria Oocysts in West African Dwarf goats at the University of Ibadan Farm

Nigerian Journal of Animal Production, 2021

An outbreak of acute coccidiosis is reported in West African Dwarf (WAD) goats kept under a semi intensive management system at the University of Ibadan farm. During the period of the outbreak, clinical signs observed among the animal included anorexia, fever, coughing, ocular and nasal discharges and diarrhoea. Sixty nine out of eighty-five (85%) animals were scouring, 6 out of 20 (30%) pregnant did abort, 8 out of 80 (10%) died through severe infection. Average oocyst counts was 2.73 x 10°/gram faeces in kids and 0.9 x 10 gram faeces in adult goats. Eimeria species predominant in goats and percentage occurrence were E. arloingi (77.5%), E. ninakohlyakimovae (62.89%), E. hirci (58.6%). E, alijevi (39.5%). Areas of glandular degeneration and necrosis of epithelium of the small intestine were seen. Also coccidia schizonts, immature oocysts, and neutrophilic infiltrations can be seen in the intestinal mucosa. The presence of pathogenic species of the Eimeria in WAD goats suggest that ...

Management and Control of Eimeria Infection in Goats

Goat Science - Environment, Health and Economy [Working Title], 2021

Coccidian parasites of the genus Eimeira cause coccidiosis in farm animals, which develop in both the small and the large intestines. Coccidiosis is a major economic concern in many livestock, especially in young animals, as a result of losses caused by clinical infection (diarrhea) and subclinical (poor weight gain in particular) and the required treatment costs. Herein, we summarize geographical distribution of Eimeria parasites, their life cycle, pathogenesis, clinical signs, economic losses due to coccidiosis, diagnosis, recent information on control and prevention, and anticoccidial drugs for Eimeria infection in goats. With regard to poverty alleviation in most developing agricultural countries, it is important to maintain and develop goat-related industries. Proper management should be used to prevent losses and reduce the productivity from coccidiosis in young animals by: reducing the level of environmental contamination by infectious oocysts; minimizing stress; and avoiding...

Identification of the Eimeria species present in goats (Capra aegagrus hircus) in Nuevo León, Mexico

Revista MVZ Córdoba, 2022

Objective. To identify, describe and determine the frequency of species of the genus Eimeria from goat feces from the state of Nuevo Leon, Mexico. Materials and methods. From 403 samples of goat excreta from 13 municipalities of Nuevo Leon, Mexico. Subsequently, after sporulation of the parasite dispersal forms (Oocysts), identification was made according to their morphology and morphometry by means of histograms and linear regression analysis. Results. A total of 60.29% of the animals sampled were positive for the presence of oocysts of Eimeria spp. The municipalities in which this parasite was most frequently detected were Ramones and Pesquería with 100% of positive samples, while a lower frequency was observed in the municipality of Aramberri with 3.4%. The morphological and morphometric analysis of the sporulated oocysts allowed the identification of 8 different types of Eimeria in the group of animals studied: E. caprina, E. caprovina, E. christenseni, E. ninakohlyakimovae, E. jolchijevi, E. alijevi, E. arloingi and E. apsheronica. Conclusions. Most of the identified Eimeria spp. showed a high degree of polymorphism. According to their morphometric characteristics, eight species were identified, including E. apsheronica, which has not been previously described in Mexico. Further studies of Eimeria species circulating in goats in Mexico are required.

Eimeria species in dairy goats in Brazil

Veterinary Parasitology, 2012

The focus of this work is to determine the distribution and identify species of Eimeria parasites of dairy goats in the livestock of the National Goat and Sheep Research Center in Sobral, State of Ceará, Northeast Brazil. Results showed the presence of multiple species in 196 of 215 analyzed samples (91.2%). Fifty five out of these were from kids (28%) and 141 from adult goats (72%). Eight different Eimeria species were identified and their prevalence in the herd was: Eimeria alijevi Musaev, 1970 (26.. Moreover, E. ninakohlyakimovae showed higher prevalence in kids (97%), followed by E. arloingi and E. alijevi (88%). On the other hand, E. alijevi (77%) was more common in adult goats followed by E. hirci (74%) and E. ninakohlyakimovae (70%). The species E. caprina had low frequency in both kids (27%) and adult goats (13%). Data indicated that infection was relatively common among kids and adult goats. The implementation of a routine diagnostic strategy can be useful in maintaining Eimeria populations under monitoring and will enable the determination of its potential impact on dairy goat herds in Northeast Brazil.
