Prevalence Of Bovine Fasciolosis Research Articles

Prevalence of bovine fasciolosis and direct financial losses in cattle slaughtered in Bamenda and Bafoussam abattoirs, Western Highlands, Cameroon.

Bovine fascioliasis is a parasitic disease that affects cattle. It leads to direct and indirect great economic loss due to animal mortalities, growth retardation and expenditure on anthelmintics, reduction livestock productivity and essentially condemnation of infected liver by inspection service. The study was carried out to determine the seasonal prevalence and estimated financial losses of fascioliasis in cattle in the Western Highlands of Cameroon. A total of 2167 cattle were selected. Later, the cattle, have being the carcasses, were dissected, and the livers were dissected and carefully examined for adult liver flukes. Faeces were collected immediately after the cattle were killed and examined using the formol-ether concentration technique. Condemned livers were weighted to estimate the financial losses using the average price of a kilogram of liver. A total 428 of cattle were found with infected livers or egg in the faeces giving a total prevalence of 19.75%. Among the infected carcass, 18.64% had both the Fasciola eggs in the faeces and flukes in the liver while 1.10% had only flukes in the liver. Results revealed that prevalence of Fasciola spp. was significantly higher during the rainy season (23.48%) than 16% in the dry season (p=0.00). A significantly (p=0.000) higher prevalence was also observed in females (33.9%) than in males (13.1%). Age range showed significant (p=0.000) influence with the animals of 8-10 years old recorded the highest prevalence of 39.3%. Furthermore, 433.1kg of liver was condemned giving a direct financial loss of 1221,550 FCFA (2049.64 USD) and an annual financial loss due to liver condemnation estimated to 1814,775 (3045.01 USD). Findings of this study indicated that bovine fascioliasis is prevalent in cattle in the Western Highlands of Cameroon, and it leads to an important financial loss particularly in the rainy season.

Correlation between the Fasciola hepatica infection rate (number of parasites in the liver parenchyma) and the antibody titration, detected by ELISA assay.

This study aimed to demonstrate the existence of a possible correlation between the level of liver fluke infection in cattle caused by Fasciola hepatica and the titers of anti-parasite antibodies in the blood. 113 blood samples were taken from non-dewormed pasture cattle in the communal slaughterhouse of the Jijel city in order to determine the serological titration of anti-fluke antibodies by the ELISA method. After slaughtering the animals studied, a count of parasites present in the inspected livers was carried out in order to assess the level of parasitic infection. The prevalence of bovine fasciolosis (due to Fasciola hepatica) based on counting the number of flukes in the inspected livers was around 61.06%, while the seroprevalence obtained is 55.75%. The sensitivity and specificity of the ELISA test used in this study were, respectively, 91.3% and 100%. A very strong correlation (r = 0.93 to p < 0.0001) was statistically demonstrated between the antibody titers and the number of flukes in the inspected livers. According to the results of this study, there is a strong statistical correlation between serum antibody titers and the number of flukes present in the liver (the higher the number of parasites in the liver, the higher the level of anti-flukes antibodies in the blood).

Prevalence and associated risk factors assessment of bovine fasciolosis in the Imbo Region, Burundi

Fasciolosis is a zoonosis that limits the productivity of ruminants worldwide, but there is a lack of information on its occurrence in Burundi. Therefore, this study aimed to fill the information gap by determining the prevalence and risk factors associated with bovine fasciolosis in the Imbo Region of Burundi. Two prevalence studies were conducted in parallel in the five communes of the five provinces in the Imbo region. In the first study, a total of 426 fecal samples were collected from randomly selected cattle farms and microscopically examined to determine Fasciola egg burden. Survey data on cattle husbandry were collected from owners of these cattle and analyzed to determine the risk factors for bovine fasciolosis. In the second study, 467 cattle were randomly selected in abattoirs and their livers were examined postmortem to determine liver fluke burdens. Data were entered separately into Microsoft Excel and analyzed using R software. The overall prevalence of bovine fasciolosis was 47.7% (42.9–52.4, 95% CI) for microscopic examination and 33.2% (28.9–37.5, 95% CI) for postmortem examinations. The majority of positive cattle (60.6%) had light intensity infections as determined by eggs per gram of feces (epg). Postmortem examinations corroborated these results and indicated that 80% of cattle had light intensity infections. Chi-square analysis showed a statistical association with the presence of bovine fasciolosis and the age, sex, and origin of cattle and the practices of cattle owners (P < 0.05).

Coprological and postmortem assessment and economic significance of bovine fasciolosis in cattle slaughtered at Tarcha Municipal Abattoir, Southern Ethiopia

Bovine fasciolosis caused by Fasciola hepatica and Fasciola gigantica, is a neglected tropical snail-borne trematode disease of cattle that poses an adverse effect on animals' health culminating in economic damage. Cross-sectional investigation on coprological and postmortem assessment and economic significance of bovine fasciolosis in cattle slaughtered at Tarcha Municipal Abattoir, Southern Ethiopia through simple random sampling techniques was conducted from December 2020 to August 2021. Out of 384 cattle examined, 20.3% and 29.94% were found harboring Fasciola through coprological examination and postmortem examination respectively. The leading cause of fasciolosis in the study area was Fasciola gigantica (53.9%) as compared to F. hepatica (46.1%). The investigation revealed that the sex, origin, and body condition of the cattle has a statistically significant effect on the prevalence of bovine fasciolosis. The odds of male animals infested with fasciolosis were 2.25 times higher than female cattle and those of poor body-conditioned cattle were three times higher than cattle with good body condition. In postmortem examination, an average of 6 flukes were found in a single infested liver and the mean fluke count was (10 ± 1.97) in severely infested livers while in lightly infested livers (3± 1.79). Considering postmortem examination as the gold standard for diagnosis of fasciolosis, the sensitivity of the direct sedimentation technique was found to be 68% and the specificity 100% with substantial agreement (k = 0.74) between the two methods. The estimated yearly direct financial losses incurred owing to fasciolosis was around 2,227,536 2, Birr (47,945.24 USD). Thus, bovine fasciolosis is one of the economically important animal diseases in the study area, which necessitates integrated control measures to tackle its effect on animal health and subsequent economic impact.

Influence of irrigation type in the prevalence of bovine fasciolosis, Cajamarca-Peru

Fasciolosis is a relevant zoonotic disease in the Peruvian Andes, it causes considerable economic losses by reducing cattle productivity and currently, resistance to anthelmintics is reported, so it is necessary to find new ways to comprehensively control this parasitosis. In this context, the objective of this study was to demonstrate the influence of the type of irrigation on the prevalence of bovine (Bos taurus) fasciolosis in dairy production units in the province of San Marcos, Cajamarca region, Peru. A total of 20 dairy cattle were introduced in two farms with different irrigation systems: traditional or flood irrigation (n = 10) and technified or sprinkler irrigation (n = 10). Starting in March and for ten consecutive months they were fed the rations produced on the farms and the prevalence of fasciolosis was monitored using the coproparasitological technique of natural sedimentation. In the livestock unit using flood irrigation, eggs excretion began in August, with a final prevalence of 60%; while in the livestock unit using sprinkler irrigation, the first cases were detected in September and the final prevalence was 20%. To the results, Fischer’s test determined that there was no association between the prevalence of the parasite and the type of irrigation (p=0.1698). The study suggests that the prevalence of fasciolosis in cattle fed rye-grass (Lolium perenne) / clover (Trifolium repens) grown with flood irrigation was higher than that of sprinkler irrigation; however, it is recommended to investigate with a larger number of samples and use more specific diagnostic methods.

Prevalence of Bovine Fasciolosis in and Around Anchar Woreda, West Hararghe, Eastern Ethiopia

The present study was conducted from April 2015 up to the end of November 2015 in the west Hararghe Zone, Oromia region, Eastern part of Ethiopia in and around Anchar district with the aim to determine or to know the prevalence of bovine fasciolosis in and around Anchar and to recommend the controlling method of fasciolosis in study area. The method employed in the study area was sedimentation technique. A total of 385 were selected randomly from the study populations and from the total examined 79 (20.5%) cattle were positives for fasciolosis. The recorded fasciolosis prevalence was varying from 18.9% to 25.5% in the different sites of the study area and the overall prevalence rate of 20.8. The prevalence of disease in age (young) 2.45% and Adult 28, 89% Sex (Male) 1.63% and female 37.81% and body condition (poor) 22.1% and 19.46% was recorded.

Epidemiological Survey and Confirmation of Autochthonous Cases of Bovine Fasciolosis in the Serrana Mesoregion of Santa Catarina, Brazil

Fasciola hepatica is reported as a trematode of great importance, causing fasciolosis, one of the most neglected zoonotic parasitic diseases in the world. In Brazil, potential losses of around US$ 210 million per year were calculated, with bovine fasciolosis alone. The State of Santa Catarina is located in the South Region of Brazil, with a herd of more than 4 million ruminants. The Serrana Mesoregion, historically free of fasciolosis, is composed of 30 municipalities, which have a consolidated agricultural tradition, mainly in extensive ruminant livestock. The objective of the present work was to investigate the occurrence and distribution of autochthonous cases of bovine fasciolosis in the region. For this, different analyzes were carried out in rural properties from eight municipalities, and in three slaughterhouses under the State Inspection Service (SIE), which received animals from all the Serrana Mesoregion. The rural properties were randomly selected, and up to 20 fecal samples were collected from random cattle older than 1 year, for analysis by coproparasitological sedimentation test. The traceability records of the positives were checked, for identifying autochthonous cases. Additionally, the tracking data of cattle slaughtered between the years of 2018 and 2021, which presented liver condemnations, were analyzed for defining autochthonous cases of bovine fasciolosis. In total, there were fecal samplings in 106 farms, with 1,927 tested cattle. From these, 178 (9.2%) were positive and autochthonous, but the overall result did not reflect the heterogeneity found between the evaluated municipalities. During the analyzed period, 11,556 cattle were slaughtered, with 1,744 (15.1%) liver condemnations due to fasciolosis in animals that never left the Serrana Mesoregion. The present study confirmed the presence of autochthonous cases of bovine fasciolosis in municipalities of the Serrana Mesoregion, and verified a high rate of positivity in animals slaughtered in the regional slaughterhouses. When the prevalence of bovine fasciolosis in vivo was compared with the postmortem positivity index in five municipalities, the results disagreed in four municipalities (p-value < 0.05), emphasizing the need for field investigation for the better understanding of the distribution and frequency of the parasitosis.

Prevalence of Bovine Fasciolosis and its Financial Loss at Gulliso Slaughter House, West Wallaga Zone Western Ethiopia

A cross-sectional study conducted in Guliso, from September 2021 to June 2022 sought to identify the kind and prevalence of common Fasciola species in cattle as well as the financial damage resulting from liver condemnation. The study's foundation was a post-mortem examination of the livers of animals that had been killed at the abattoir in the Guliso municipality and its environs. 384 study animals were chosen for post-mortem examination using random systematic sampling procedures in this investigation. In the study, 128 (33.3%) cows had bovine fasciolosis overall. 54 animals (14.1%) had Fasciola gigantica, 49 animals (12.3%) had Fasciola hepatica, and 25 animals (6.5%) had mixed infections. Within the various body condition ratings, there was a significant difference (P&lt;0.05) in the prevalence of bovine fasciolosis. Animals with poor and medium body condition ratings had the highest prevalence (96%) and lowest prevalence (84.7%), respectively, whereas animals with good body condition scores had the lowest prevalence (9.73%). Regarding age, sex, and animal origin, there was no statistically significant difference (P&gt;0.05) in the prevalence of bovine fasciolosis. The estimated yearly financial loss at the abattoir resulting from liver condemnation linked to liver flukes was 138,528 Ethiopian birr. Given the current findings, fasciolosis may be viewed as a serious issue in the area and its environs since the ecological parameters and management circumstances support the survival of both the parasite and its intermediate host, the snail. To prevent pasture contamination and lower the worm burden from affected animals, strategic treatments must be applied at the right time. To maximize the long-term returns from such endemic locations, integrated control techniques involving livestock owners must be developed to reduce the population and activity of snail intermediate hosts.

Coprological Prevalence and Associated Risk Factor of Bovine Fasciolosis Around Furda Veterinary Clinic, East Hararghe, Ethiopia

Aim This study was conducted using the sedimentation method to assess the prevalence and associated risk factors of bovine fasciolosis around Furda Veterinary Clinic, East Hararghe, Ethiopia. Method A cross-sectional study design was conducted from October 2020 up to June 2021 to know the prevalence and its associated risk factors of bovine Fasciolosis, taking animal origin, sex, age and body condition as risk factors and standard deviation. The sedimentation technique was used for the recovery of fasciola eggs from fresh fecal. Results From a total of 384 animals selected randomly and coprologically examined, 117 of them contained fasciola eggs with a 30.5% total prevalence in the study area. The prevalence of bovine fasciolosis on the basis of animal origin was highest in Gorowodo 23 (28.7%), followed by Dada 24 (30.4%), Harawa 15 (20.5), Rasa Janata 25 (33.8%), and Tirtiro 30 (38.5%). Based on the sexes of animals, the prevalence rate of 74 (32.7%) in females and 43 (27.2%) in males were obtained. While animals of different ages were recorded at 43 (29.9%) and 74 (30.8%), respectively. Whereas 44 (33.6%), 45 (28.8%), and 28 (28.9%) were found to be in poor, moderate, and good physical condition, respectively. All of the risk factors investigated (animal origin, sex, age, and body conditions) were found to be non-significantly associated with the prevalence of bovine fasciolosis (p&gt;0.05). Conclusion This study reveals that bovine fasciolosis was a highly prevalent disease in the study area and needs immediate control and prevention by the animal health office and veterinarians working together, treating cattle with anthelmintics before and after the rainy season, and increasing owner awareness about the disease.

Prevalence of fasciolosis (Liver flukes) infection in cattle in Zamfara, Nigeria: A slaughterhouse surveillance data utilizing postmortem examination

Bovine fasciolosis, caused by Fasciola gigantica (F. gigantica) and rarely F. hepatica, is an economically important disease affecting cattle in tropical Africa. The aims of this study were to determine a year prevalence of bovine fasciolosis and correlate determinants of infection in slaughtered cattle at the municipal abattoir in Zamfara, Nigeria. Fasciola gigantica was detected in 15% (1740/11,562) cattle slaughtered during a daily postmortem examination (PME) between November 2016 and October 2017. This approach demonstrated an increase risk of liver fluke infection in older cattle (p=0.001, AOR=1.476, 95% CI: 1.188-1.832) and during rainfall (p=0.003, AOR=1.604, 95% CI: 1.176-2.187). Liver condemnation had been significantly found in hot-dry season (p≤0.001, AOR=0.518, 95% CI: 0.417-0.643) and adult cattle (p=0.003, AOR=1.726, 95% CI: 0.586-0.899). This study is an account of bovine fasciolosis prevalence and infection dynamics in part of the northwest region of Nigeria, which provides preliminary information for further studies to guide the design of appropriate control steps to lower the impact of the disease and safeguard public health.

Economic model of bovine fasciolosis in Nigeria: an update.

Bovine fasciolosis is a zoonotic infection transmitted by infected freshwater snail-Lymnaea (Radix) natalensis-in tropical regions. The prevalence of bovine fasciolosis in Nigeria is overwhelming with huge financial cost. In the chronic form of the disease, hyperplastic cholangitis and calcification of bile ducts occur with severe liver damage. The aim of the study was to estimate annual economic losses of bovine fasciolosis in Nigeria. Disease prevalence was estimated at 18.3% (8.5-30.6), average annual disease incidence is maintained at 2.5%, an estimated mortality rate of 1.5%, a total liver condemnation rate of 11.1% were estimated from affected liver due to fasciolosis, annual slaughter rate of 10.5% and a total cattle population of 20 million. A total of 7.3% livestock owners consider fasciolosis as a threat, while only 4.3% have ever used molluscicide. Treatment cost of controlling fasciolosis is estimated at US$375,000, which puts the total annual loss due to fasciolosis at US$26.02 million. Both direct and indirect sources of production losses have an impact on the livestock industry in Nigeria. Bovine fasciolosis threatens food security in Nigeria; therefore, further awareness among livestock owners is needed on control strategies to improve the income base for small-scale livestock farmers.

Prevalence of bovine fasciolosis from the Bolgatanga abattoir, Ghana

Fasciolosis is a neglected tropical foodborne trematodiasis caused by Fasciola hepatica and Fasciola gigantica. It is a widely distributed infection in livestock in Africa but its disease situation is less understood in many countries such as Ghana. In the present study, a cross-sectional survey was conducted at the Bolgatanga abattoir, in the Upper East Region of Ghana, to determine the prevalence and distribution of bovine fasciolosis and the Fasciola species involved. A total of 263 cattle were screened at slaughter and isolated Fasciola flukes were molecularly identified to species level by PCR-RFLP of the 28SrRNA gene using Ava II endonuclease. Fasciolosis prevalence was 10.27% across all age categories, and female and male animals were affected alike. Fasciola species differentiation revealed Fasciola gigantica in all cases. This study confirms the occurrence of F. gigantica and its predominance in Ghana Upper East Region and provides basal data for further investigations into the prevalence of Fasciola spp. in other parts of Ghana and neighbouring countries.

Prevalence of Bovine Fasciolosis in Selected Dairy Farms of Addis Ababa, Ethiopia

A cross sectional study is carried out in selected dairy farms in and around Addis Ababa on the prevalence of fasciolosis in Ethiopia, in four sub-cities, locally called Kifele Ketemas. The dairy farms were under intensive and semi-intensive management systems. A total of 384 cattle were randomly selected and sampled which accounts for 95% (N=365) and 5% (N=19) of the samples for intensive and semi-intensive dairy farms, respectively. Fecal samples were examined using the direct fecal microscopic examination and Benedict's sedimentation tests. Out of 384 samples examined, 57 samples were found to be positive using both tests, giving a prevalence of 14.84% (N=57). The prevalence of fasciolosis in study areas (Kifele Ketemas) is 52.63% (N=30) in Yeka, 33.33% (N=19) in Bole, 10.35% (N=6) in Gullele and 3.51% (N=2) in Kality area. The prevalence of bovine fasciolosis in Yeka is significantly higher (P 0.05) is observed between the age groups. Keywords: Bovine; Fasciolosis; Prevalence; Chi-square; Addis Ababa; Ethiopia.

Study of Prevalence and Associated Risk Factors of Bovine Fasciolosis in Jimma Horro District of Kellem Wollega Zone, Western Ethiopia

Fasciolosis is a parasitic disease of cattle that cause a significant economic loss in cattle production in Ethiopia. A cross-sectional study was conducted with aim of assessing prevalence and associated risk factors of bovine fasciolosis in Jimma Horro district from November 2016 to November 2017. Fecal samples from randomly selected 384 cattle of different age group, sex and body condition were collected and examined with parasitological techniques (sedimentation technique). The prevalence of bovine fasciolosis as determined from coprological examination was highest in Une (31.3%), followed by Makanisa (29.2%), Abono (26.1%) and Ilu Kitaye (24.0%) peasant associations. The overall prevalence of bovine fasciolosis was 27.6% (106/384) in the study areas. Multivariable logistic regression analysis identified season (OR= 4.6), sex (OR= 6.1), age groups (OR= 32.4) and body condition (OR= 5.8) of cattle as risk factors (P 0.05). The present finding shows that fasciolosis in cattle is the most economically important parasitic disease affecting cattle and common in Jimma Horro district. Hence, there is a need to create awareness about impact of disease on cattle production and appropriate control methods of fasciolosis should be designed and implemented. Further epidemiological investigation should be carried out in the study area.
