Background and Aim: Eimeria spp. are gastrointestinal protozoans that affect animal productivity, thereby causing symptoms that range from bloody diarrhea to death. These symptoms cause economic losses to farmers. The distribution of Eimeria spp. in cattle has, therefore, been reported to have spread widely, especially in the tropics and subtropics. Indonesia is a tropical country at high risk of Eimeria infections. This study aimed to identify the prevalence and risk factors related to the levels of eimeriosis in beef cattle originating from different geographic areas in Indonesia. Materials and Methods: Here, 817 fecal samples were collected from beef cattle in Indonesia, including 282 calves, 535 adults, 530 males, and 287 females. In addition, 156 semi-intensively and 661 intensively managed cattle were randomly collected. Then, fecal samples were analyzed by parasitology examinations. Results: Screening examination using the sugar flotation modification method showed that Eimeria spp. were prevalent in Indonesia, as 65.4% of the bacterial strain was detected. The prevalence of identified Eimeria spp. in Indonesia was highest in North Maluku (Maluku Island) (94.1%), whereas the lowest levels were observed in West Java (24.0%) (Java Island). The prevalence was also found to be higher in males (79.3%) than females (51.9%). Similarly, levels in semi-intensively managed cattle (66.7%) were higher than those subjected to intensive management (65.9%). However, its prevalence in calf and adult cattle was similar. Conclusion: Bovine eimeriosis spp. were detected at high prevalence in Indonesia, and high-level risks were observed in infected males, including those under the semi-intensive management. In addition, although the results from oocyst examinations were based on qualitative analysis, the endemicity levels of Eimeria spp. among farms in Indonesia should be considered because Eimeria spp. were distributed in most parts of Indonesia. Based on the results of this study, we provide the first information about the prevalence of bovine eimeriosis from different geographical locations in Indonesia, which have differing climates associated with the level of the existing risk factors. Hence, farmers are advised to pay more attention to strict biosecurity techniques on their farms, thereby favoring the early control of bovine eimeriosis.

AbstractA total of 350 faecal samples from unweaned alpacas over 3 months of age were collected from 23 herds in order to determine the prevalence of Eimeria spp. in Southern Peru and to identify the risk factors associated to Eimeria infection in young alpacas. Samples were examined by a flotation technique and the identification of risk factors was assessed by a logistic regression analysis. Sixty four percent of the examined animals shed Eimeria oocysts; herd prevalence was 96%, with an intra-herd prevalence of 60% (range 5.9-100%). Five different Eimeria species were identified, being E. lamae (91%), E. alpacae (87%) and E. punoensis (78%) the most prevalent; E. macusaniensis (35%) and E. ivitaensis (13%) were less common. Mixed-species infections were more frequent (78%) than single infections (22%). E. lamae was the most common monospecific infection and E. lamae/E. alpacae the most frequent association. The geographical area has a significant effect on Eimeria infection rates (74.9% wet Puna vs 37.4% dry Puna) as well as the breeding system (65.1% traditional vs 63.8% modern). In contrast, the sex of the animals (64.6% males vs 64.0% females) showed no influence on the prevalence of infection by Eimeria. The high prevalence found at both individual and herd level and the common presence of highly pathogenic Eimeria species may lead to important economic losses for alpaca breeders and could require the implementation of suitable control measures.

Bovine trichomoniasis is a venereal disease that causes substantial economic losses to the cattle industry worldwide. It has been endemic in the USA since its discovery in the 1930s. The reasons for this long-lasting endemism are poorly understood. The main objective of this study was to identify herd-level risk factors for trichomoniasis in Wyoming beef cattle. A questionnaire was sent to all Wyoming beef cattle producers. The overall response proportion was 23.4 %. Questionnaires were returned from producers throughout the state in different geographical regions and with various herd sizes. In total, 863 questionnaires were analysed for correlation between the disease endemism and 25 variables. Tritrichomonas foetus infections were found to be significantly (P<0.05) associated with neighbouring a positive herd(s), grazing on public allotments and commingling with other herds. In addition, a delay in fixing broken fences approached statistical significance (P = 0.078). This study provides producers with valuable information and useful suggestions on how to effectively control and reduce the risks of bovine trichomoniasis.

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 &lt; 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. &nbsp;

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 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.

Eimeria infections are common in sheep industry worldwide, however information about their epidemiology is scarce in southern state of Rio Grande do Sul, Brazil. Therefore, a cross-sectional study was carried out to determine the prevalence, species characterization, and associated risk factors between Eimeria species and sheep flocks. Fecal samples from 428 sheep from 21 farms were tested for the presence of oocysts. The overall prevalence of Eimeria spp. was 68.69% and was significantly affected by age of the sheep, with highest prevalence in animals under 18 months of age. Eight Eimeria species were identified. Eimeria ovinoidalis (85.71%) was the most common, followed by Eimeria crandallis (80.95%), Eimeria granulosa (78.95%), Eimeria ahsata (61.90%), Eimeria faurei (42.86%), Eimeria bakuensis (38.10%), Eimeria punctata (14.29%), and Eimeria pallida (9.52%). All herds were positive, with concomitant infections. Among management and husbandry practices; farm size, animal density, farming system, breeding objectives, and pasture system influenced the prevalence of Eimeria species. The infection was more prevalent on small farms with high animal density, in sheep raised for meat, semi-intensive system, and rotational grazing (p < 0.05). The wide distribution of this protozoan and the high frequency of pathogenic species show the importance and potential damage of coccidiosis in sheep flocks in Rio Grande do Sul.

Poultry Coccidiosis

Coccidiosis is one of the most prevalent and economically important parasitic diseases caused by the infection with Eimeria species contributing to major economic losses of poultry industry worldwide. In this study, occurrence of Eimeria spp. in chicken reared under different management systems was studied. A total of 300 faecal samples from chicken were collected from six organised poultry farms and six backyard poultry units in and around Thrissur, Kerala. Out of this, 167 faecal samples were from organised farms and 133 from backyard poultry units. All the samples were artificially sporulated and examined for studying the oocysts morphology and morphometry. Out of 167 samples from organised farms 52 were found to be positive for Eimeria spp. while 61 out of 133 samples from backyard poultry were positive. The overall occurrence of Eimeria spp. in chicken from 12 different areas in and around Thrissur was 37.66 per cent (113/300). The species of Eimeria identified on morphological examination were E. tenella, E. necatrix and E. maxima. The occurrence rate of E. tenella was found to be significantly higher (46.01 %) compared to E. necatrix (39.82 %) and E. maxima (14.15 %). The rate of occurrence of Eimeria spp. infection was significantly higher in backyard poultry (45.86 %) compared to that in organised farms (31.13 %).

Abstract The present study aimed to perform an epidemiological and morphological identification of Eimeria infection in sheep in Brazil. Fecal samples from sheep were collected from 20 farms in northern Paraná, Brazil. An epidemiological questionnaire was used to evaluate the risk factors. Fecal samples containing oocysts per gram of feces (OoPG) ≥1000 were subjected to the modified Willis-Mollay method to perform oocyst identification. Sporulated oocysts were observed microscopically for morphological identification. A total of 807 fecal samples were collected. Based on the morphological characteristics of the sporulated oocysts, 10 species of Eimeria were identified, with main species observed: Eimeira ovinoidalis (98.1%), Eimeria crandallis (87.6%), Eimeria parva (79.1%), and Eimeria bakuensis (60.8%). Only 2.6% (7/268) of the sheep were infected with a single species, 4.8% (13/268) contained two different species, and 92.5% (248/268) were infected with three or more species. The analysis of risk factors showed that an intensive rearing, no rotation of pasture, dirt, and slatted floors, and age up to 12 months were associated with infection. This study showed a high prevalence of Eimeria natural infection in sheep from northern Paraná, Brazil. Furthermore, based on the risk factors, good management and hygiene practices must be employed to avoid infection.

Faecal samples were collected from a total of 11 calves on three dairy farms (four from two farms and three from one) where calves generally thrive well and no anti-coccidial treatment is habitually carried out. One of the farms keeps calves in groups on hay/straw bedding, one keeps calves in pairs on plastic slats and then in groups on concrete slats, and the third one keeps calves in groups on concrete slats. Faecal consistency and the total number of Eimeria spp. oocysts per gram faeces (OPG) were determined and species identification was carried out by morphology. Eimeria oocysts were detected in all calves at some point of the study period, and diarrhoea was seen in 55% of the calves. The highest peak in oocyst excretion was 69,300 OPG. The first peak in oocyst excretion was seen 2-3 weeks after calves had been moved to group pens, and a second peak was seen 2-3 weeks later. Nine Eimeria species were found, including E. bovis and E. zuernii. The results are in accordance with previous studies showing that one of the risk factors for Eimeria infection in calves is entering a group pen where older calves are already being kept.

Coccidiosis is a parasitic disease caused by the protozoan of the order Coccidia, the family Eimeriidae of the genus Eimeria which breeds rapidly in the digestive tract and is the most difficult disease to be controlled on cattle farms. Eimeria spp. in cattle can cause high economic losses and increase susceptibility against infectious diseases. Therefore, coccidiosis in cattle needs attention from the government. This paper reviews a number of diagnostic methods that can be used in the detection of Eimeria spp. in cattle based on the goals and objectives of the examination. The coccidiosis cases often do not show any clinical symptoms but can cause sudden death in livestock. The diagnostic method that still used at present is based on its morphology that should not be used in identifying Eimeria species because the morphological characteristics Eimeria spp. have similar shape and size structures between species (resembling morphology). An appropriate diagnostic method for Eimeria is needed in the context of controlling coccidiosis strategically.

Introduction: Parasitic diseases are a major setback to sustainable poultry production. This study determined the occurrence of Eimeria species and haemosporidia among domestic chickens and helmeted guinea fowls in live-bird markets in Lagos State, Nigeria. Methods: Blood samples and intestinal contents at three distinct segments of the gut were collected from 60 domestic chickens and guinea fowls each. Wet smears of intestinal contents were microscopically examined for oocysts typical of Eimeria species while thin films of blood were Giemsa-stained for the demonstration of protozoa. Results: Results revealed that 19(31.7%) and 21(35%) chickens and guinea fowls w er e positive for Eimeria spp. infection respectively. There was no significant difference (P>0.05) in Eimeria spp. infections between the chicken breeds nor between sexes of both birds. Oocysts of Eimeria were mostly recovered from the caeca and small intestines of the guinea fowls and chickens respectively. Domestic chickens were infected with three different haemoprotozoa: Plasmodium spp. (23.3%), Leucocytozoon spp. (6.7%) and Haemoproteus spp. (3.3%); while Plasmodium spp. (15%) and Haemoproteus spp. (3.3%) were the only blood protozoa infecting guinea fowls. The infection rates of haemosporidia between the breeds of chickens and the sexes of both birds did not differ significantly (P>0.05). Conclusion: Eimeria parasites and haemosporidia are prevalent among chickens and guinea fowls sold in Lagos State. To prevent severe economic losses in the future, appropriate control measures should be designed and implemented.
