Gastrointestinal parasites impose severe constraints on sheep production worldwide. lnformation on prevalence of helminthosis in the ovine species could provide a useful guide towards effective control. Investigated in this study was helminthosis prevalence in some Nigerian sheep. The sheep included initial 64 yearlings (12 each of Balami, BL, and Uda, UD, and 20 each of Yankasa, YK and West African Dwarf, WAD, in a sex ratio of 1:1 per breed) and their 156 offspring. Faecal samples were collected from the sheep six-weekly over a period of 3 years and examined for the presence of various helminth species using the modified McMaster technique. Total helminths, Strongyles, Strongyloides, Moniezia, Trichuris and Nematodirus prevalence were 95.9, 87.3, 38.2, 60.6, 45.0 and 46.4%, respectively. Based on prevalence, breeds and seasons ranked (p < 0.05) thus: YK = WAD > BL > UD and late rainy> early rainy> late dry > early dry. Females and older sheep (≥ 4months) had higher (p < 0.05) prevalence than males and lambs (< 4months), respectively. Prevalence increased with decreased body condition score (BCS). Year, birth type and parity did not influence prevalence. It is concluded that there is high prevalence of helminthosis in the study area, with variation between breeds, sex, age groups and seasons. These variations could be exploited through selective breeding and cross breeding to control the disease with or without minimal use of anthelminthics.     Les parasites gastro-intestinaux imposent de sévères contraintes à la production ovine dans le monde. Les informations sur la prévalence de l'helminthose chez les ovins pourraient fournir un guide utile pour une lutte efficace. La prévalence de l'helminthose chez certains moutons nigérians a été étudiée dans cette étude. Les moutons comprenaient au départ 64 yearlings (12 chacun de Balami, BL et Uda, UD, et 20 chacun de Yankasa, YK et West AfricanDwarf, WAD, dans un rapport de masculinité de 1 : 1 par race) et leurs 156 descendants. Des échantillons de matières fécales ont été prélevés sur les moutons six fois par semaine sur une période de 3 ans et examinés pour la présence de diverses espèces d'helminthes en utilisant la technique modifiée de McMaster. La prévalence totale des helminthes, Strongyles, Strongyloides, Moniezia, Trichuriset Nematodirus était de 95.9, 87.3, 38.2, 60.6, 45.0 et 46.4%, respectivement. Sur la base de la prévalence, des races et des saisons classées (p <0.05) ainsi : YK = WAD>BL> UD et pluvieux tardif> pluvieux [email protected] 13 précoce> sec tardif> sec tôt. Les femelles et les moutons plus âgés (≥ 4 mois) avaient une prévalence plus élevée (p<0.05) que les mâles et les agneaux (<4 mois), respectivement. Laprévalence augmentait avec la diminution du score de l'état corporel (le 'BCS'). L'année, letype de naissance et la parité n'ont pas influencé la prévalence. Il est conclu qu'il existe uneprévalence élevée d'helminthose dans la zone d'étude, avec des variations entre les races, lesexe, les groupes d'âge et les saisons. Ces variations pourraient être exploitées par unesélection sélective et des croisements pour lutter contre la maladie avec ou sans utilisationminimale d'anthelminthiques.

Gastrointestinal Parasitism

SummaryThe aim of the present study was to determine copro-prevalence of gastrointestinal parasites and their associated potential risk factors in pigs of Punjab (India). A total of 839 faecal samples were collected from pigs of all age group and sex from different agro-climatic zones of Punjab covering all seasons and subjected to qualitative and quantitative examination. Among the samples examined, 28.4 % were positive for gastrointestinal parasites and their respective prevalences were Ascaris suum (11.1 %), coccidia (9.41 %), Trichuris suis (6.43 %), Balantidium coli (4.5 %), amphistome (3.33 %), strongyle (2.14 %) and Ascarops strongylina (1.78 %). Upon sporulation of coccidian positive samples, 8 species of Eimeria were recorded (Eimeria polita, E. spinosa, E. scabra, E. perminuta, E. suis, E. debliecki, E. neodebliecki and E. porci). Among the various risk factors analysed, season, agro-climatic zones and managemental practices had a signifi cant (p<0.05) effect on gastrointestinal parasitism of pigs. Quantification of the infection levels in various seasons and age groups revealed the highest mean egg per gram in rainy season (1966. 6± 1146.5) and grower pigs (1457.1 ± 500.4). Coproculture analysis revealed the presence of larvae of Hyostrongylus rubidus and Oesophagostomum species. The results of the current study would be of immense help in formulation and implementation of control strategies for effective control of gastrointestinal parasitism in pigs.

The objective of this study was to evaluate the effect of grazing cowpea pastures on growth, parasite egg count and biomarkers of immune response in goats. Spanish and Savannah goats (n = 48) stratified by initial body weight (42.0±7.0 kg) and fecal egg count (FEC), were randomly assigned to three pasture forages (Cowpea varieties: Mississippi silver (MS), or Iron and Clay (IC) or Pearl millet (PM) as control with 4 replicates, for a 28-day feeding trial. Forage samples collected at the start of the study were analyzed for nutrients, chemical and polyphenols content. Body weight, body condition score, and fecal egg count were measured weekly. Blood was collected from goats on days 0 and 28 for PCV and white blood cell differential counts. The concentration of total proteins, prostaglandin E2 (PGE2) and total antioxidant capacity (TAC) were evaluated in blood serum. Concentration of DNA isolated from fecal samples was used as a measure of gut health. Goats grazed on cowpea forage (MS and IC) had higher body weight (p = 0.01) compared to goats grazed on PM. Percent lymphocyte (p = 0.008) and neutrophil (p = 0.013) increased in MS fed goats. Goats grazed on MS pasture had decreased FEC (p = 0.03) also. Cowpea pasture grazing had no effect on serum protein concentration, PCV and BCS (p > 0.05), but decreased PGE2 concentration in serum. The concentration of TAC in serum, increased at day 28 (p < 0.05). The concentration of fecal microbial DNA decreased in all the treatment groups at day 28. Cowpea forage grazing had an impact on body weight, FEC, and blood serum parameters (PGE2, TAC) in goats. These results demonstrate that freshly grazed cowpea forage has potential impact and benefits on growth and health of goats. Integrating cowpea diet in goat feeding system may enhance growth performance, stimulate and prime the immune system for defense against gastrointestinal parasites.

SUMMARYEffective control of gastrointestinal parasites is necessary in sheep production. The development of anthelmintics resistance is causing the available chemically based anthelmintics to become less effective. Biological control strategies present an alternative to this problem. In the current study, we tested the larvicidal effects ofBacillus thuringiensisvar.israelensisCry11Aa toxin againstHaemonchus contortuslarvae. Bacterial suspensions [2 × 108colony-forming units (CFU) g−1of the feces] ofB. thuringiensisvar.israelensisand recombinantEscherichia coliexpressing Cry11Aa toxin were added to naturallyH. contortusegg-contaminated feces. The larvae were quantified, and significant reductions of 62 and 81% (P< 0·001) were, respectively observed, compared with the control group. A 30 mL bacterial suspension (1 × 108CFU mL−1) ofB. thuringiensisvar.israelensisand recombinantE. coliexpressing Cry11Aa toxin were then orally administered to lambs naturally infected withH. contortus. Twelve hours after administration, feces were collected and submitted to coprocultures. Significant larvae reductions (P< 0·001) of 79 and 90% were observed respectively compared with the control group. The results suggest that the Cry11Aa toxin ofB. thuringiensisvar.israelensisis a promising new class of biological anthelmintics for treating sheep againstH. contortus.

Abstract Helminth and protozoan infections are responsible for important diseases in grazing sheep, which can be especially threatening in an autochthonous breed at risk of extinction like the Churra Galega Mirandesa Portuguese sheep breed. The aim of the present study was to determine the diversity, prevalence and burden of gastrointestinal parasites in these sheep and to assess the effects of deworming practices, cohabiting animals on the farm and feed management. Coprological qualitative and quantitative analysis (flotation, natural sedimentation and McMaster method) were used to identify and quantify gastrointestinal parasites and a questionnaire was designed and applied. A total of 512 faecal samples were collected from 49 flocks, and 49 replies to the questionnaire were received. Parasites were identified in 100% of the flocks, and in 97% of the samples. The genera or species that have been morphologically identified were: strongyle-type, Nematodirus spp., Skrjabinema spp., Moniezia expansa, Moniezia benedeni, Trichuris spp., Capillaria spp., Eimeria spp., Dicrocoelium spp. and Fasciola hepatica. This is the first report in Portugal of Skrjabinema spp. The burden of parasites’ oocysts and eggs per gram in faecal samples ranged, respectively, from 50 to 17,550 for Eimeria spp., and from 50 to 6250 for strongyle-type eggs. Factors affecting parasitic infections were evaluated using a multivariate logistic regression. Grazing time and a lack of anthelmintic treatment were positively associated with Nematodirus spp. infection. This study showed that there is a high prevalence and diversity of gastrointestinal parasites in the Churra Galega Mirandesa sheep breed.

This study was conducted with the aim of determining the dry season (January-May, 2018) prevalence of gastrointestinal parasites in special breeds of ruminants in Sokoto Metropolis. A total of 100, 85 and 75 faecal samples were collected from Sudanese breed of Sheep, WAD/Sahel Goats and Friesian Cattle respectively. Faecal samples were examined using standard parasitological techniques (Simple flotation and Centrifugal sedimentation). For the Sheep, a total of 51 samples were positive for presence of gastrointestinal parasites. Male animals have higher prevalence (52.9%) than their female (47.1%) counterparts. The major parasites observed were Eimeria and Strongyles with prevalence of (64.71%), while the least observed parasites were mixed infections (35.29%). From the total of 85 goat faecal samples examined, an overall prevalence of 54.7% was observed. The prevalence rates for Strongyle, Eimeria and mixed infections were 57.5%, 34.0% and 8.5% respectively. The prevalence was more in males than in the females. Strongyleeggs were more, compared to other helminthes eggs. For the Friesian Cattle, sixty (60) samples out of 75 samples analyzed were positive for either Strongyleeggs or Eimeria (oocyst) infection or both (mixed) constituting about 80% prevalence. Forty-two (70%) samples were positive for Strongyle eggs, 14 (23.3%) for Eimeria oocyst and 4 (6.7%) for mixed infection of both. From the overall prevalence, female had a high prevalence of 34(56.7%) than male cattle 26(43.3%). Based on the results of the present findings, it was concluded that gastrointestinal parasitic infections also occur during the dry season in Sokoto which may be as a result of carry-over of infection during the succeeding rainy season.

Bovine Fasciolosis is a vector – borne zoonosis and one of the most neglected tropical diseases that cause huge economic losses and poor animal conditions in Nigeria. The prevalence of Fasciolosis in Cattle slaughtered in the Federal Capital Territory, Abuja was investigated. Faecal samples were collected from the cattle antemortem and analysed using copro ELISA test-kits and gross lesions were inspected at postmortem. Out of one hundred and eighty six (186) faecal samples analysed, over-all prevalence was 98(52.7%). From each abattoir was 38 (38.8%), 36 (36.7%) and 24 (24.5%) at Karu, Dei-Dei and Gwagwalada abattoirs respectively. Based on body condition scoring, infection rates were 39 (58.2%), 45 (58.4%) and 20 (47.6%) from cattle with poor, moderate and good body conditions accordingly. Males had a higher prevalence rate of 48 (50%) than females with 40 (44.4%). Based on the breed of cattle, infection rate of the diseases was 41 (66.1%), 39 (62.9%) and 20 (32.3%) in White fulani, Sokotogudali and Red bororo accordingly. Out of 186 cattle inspected at postmortem, 47 livers were condemned totally due to the presence of liver flukes (Fasciola species) in the hepatic parenchyma, fluke tracts, livers were friable and chirrotic. This led to an estimated loss of about three million, one hundred and two thousand naira (3,102,000.00). There was no statistically significant association between the infection and breed, sex and body condition score (p>0.05). Treatment of all cattle with an effective flukicides, vector control, enlightening of cattle farmers for proper intervention against fasciolosis are recommended.

AbstractA study on the prevalence and intensity of Toxocara canis (Werner, 1782) in dogs was carried out in Ile-Ife, Nigeria. Faecal samples were collected from 269 dogs between January and December 2004, processed by the Kato–Katz technique and then examined for T. canis eggs. The prevalence of T. canis obtained was 33.8%. The intensity of infection, measured as mean egg count per gram of faeces ( ± SEM) was 393.8 ± 83.4. The prevalence and intensity of T. canis in dogs aged 0–6 months were significantly higher (P < 0.05) than older age groups. The prevalence and intensity of T. canis infection were significantly higher in males than in female dogs (P < 0.05). Since T. canis is known to cause visceral larva migrans (VLM) in young children, there is the possibility that the high prevalence of T. canis infection obtained in this study might constitute an important risk factor for transmission to humans. Therefore, there is the need to educate the residents of Ile-Ife on the danger of close association of their children with household pets.

AbstractA study of gastrointestinal parasites in 269 faecal samples from dogs (Canis familiaris) collected from Ile-Ife, Nigeria between January and December 2004, revealed seven helminth species:Toxocara canis33.8%,Ancylostomasp. 34.6%,Toxascaris leonina3.3%,Trichuris vulpis3.7%,Dipylidium caninum4.1%,Uncinaria stenocephala0.7% andTaeniasp. 1.1%. The faecal egg intensities, determined as mean eggs per gram of faeces ( ± SEM) were:T. canis393.8 ± 83.4,Ancylostomasp. 101.5 ± 32.8,T. leonina14.3 ± 7.9,T. vulpis3.4 ± 1.5,D. caninum2.2 ± 0.8,U. stenocephala0.2 ± 0.2. The prevalence of intestinal parasites was significantly higher (P < 0.05) in dogs of age 0–6 months than in older age groups. There was no significance difference in overall prevalence of intestinal helminth parasites between male (58.3%) and female (50.0%) dogs (P>0.05). The prevalence of helminth parasites was significantly higher (P < 0.05) in free-ranging than in kennelled dogs. The prevalence of helminth parasites was also significantly higher (P < 0.05) in African shepherds than in Alsatians and other exotic breeds. Each helminth parasite had similar prevalences and intensities among both genders (P>0.05) except inT. vulpis. The overall prevalence of intestinal parasites may continue to rise due to lack of functional veterinary clinics for dog care in Ile-Ife. Therefore, there is the need to establish a veterinary facility in Ile-Ife.

Helminth parasites have been recognized as one of the major constraints to both goat and sheep production in Nigeria and other developing countries. A study aimed to determine helminth parasites of goats and sheep at slaughter in Lafia from June to July 2019. Two hundred fecal samples were collected and analyzed from 100 goats and 100 sheep using the direct smear method. The fecal sample examined revealed an overall prevalence of 155(77.5%), with goat having 80(80.0%), sheep 75(75.0%). Thirteen helminth parasites were found with nematode the most prevalent 103(66.5%), trematode had 35(22.6%), and cestode the least with 17(10.1%) and there was a statistically significant difference among the parasites (P<0.001). According to sex, females 59(43.7%) were more infected than males 25(38.5%) and there was a statistically significant difference (P<0.001). Age of sampled animals (Goat and Sheep) shows that <1 year had 28(18.1%), younger animals within the ages of <2 years 65(41.9%) were more infected with helminth parasites than adult animals from <3 years (13.5%) and >33 had 25(16.1%) and there was no statistically significant difference in age (P>0.312). According to breeds, the West African dwarf goats and sheep were more infected 104(52%), the Fulani breeds 73(36.5%) and the least was Balami sheep with 13(6.5%), Uda goat 10(5%) and there was a statistically significant difference among the breeds (P<0.001). This study revealed a high prevalence of helminth parasites of goat and sheep at slaughter in Lafia which may reduce productivity. It is recommended that goats and sheep be dewormed regularly.
