Abstract
PURPOSE In the present study, gastrointestinal parasites (GIP) prevalence in sheep and goats from India was estimated by scientometrics. METHODS The GIP prevalence studies (86) reported during 1998-2021 was obtained from online databases, and offline literatures, meta-analysis was undertaken by using "meta" package in R-Software. RESULTS The pooled GIP prevalence in India was 65% (95% level CI 56-74%, PI 12-96%) in sheep, 74% (95% level CI 66-80%, PI 14-98%) in goats and 68% (95% level CI 62-73%, PI 15-96%) in sheep and goats. Period-wise analysis revealed a higher GIP prevalence during 1998-2010 than the recent periods. Among the zones, GIP prevalence was higher in the Central zone (79%) in sheep, North zone (82%) in goats, and Central zone (78%) in sheep and goats. Based on the state-wise analysis, a higher GIP prevalence was observed in Haryana for sheep, Himachal Pradesh for goats, and Uttarakhand for sheep and goats. In India, a higher prevalence was reported by nematodes than other parasite classes. Based on climatic regions, a higher GIP prevalence was observed in semi-arid Steppe type region (84%). CONCLUSION The high prevalence zones, states, species, sample types, parasite classes, parasite species and climate regions of GIP will be useful in decision-making and resource use efficiency by policymakers and stake holders. There is an urgent need to prevent the occurrence of GIP infections in sheep and goats by adopting scientific management practices, effective therapeutic measures, and hygienic practices on farms to augment the economic benefits to sheep and goat farmers in India.

A comparison of Mini-FLOTAC and McMaster techniques, overdispersion and prevalence of parasites in naturally infected North American bison (Bison bison) in the USA. CURRENT RESEARCH IN PARASITOLOGY & VECTOR-BORNE DISEASES 2022; 2:100103. [PMID: 36437837 PMCID: PMC9684701 DOI: 10.1016/j.crpvbd.2022.100103] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 06/27/2022] [Revised: 10/31/2022] [Accepted: 11/01/2022] [Indexed: 11/09/2022]
Abstract
Several quantitative diagnostic techniques are available to estimate gastrointestinal parasite counts in the feces of ruminants. Comparing egg and oocyst magnitudes in naturally infected samples has been a recommended approach to rank fecal techniques. In this study, we compared the Mini-FLOTAC (sensitivity of 5 eggs per gram (EPG)/oocysts per gram (OPG)) and different averaged replicates of the modified McMaster techniques (sensitivity of 33.33 EPG/OPG) in 387 fecal samples from 10 herds of naturally infected North American bison in the Central Great Plains region of the USA. Both techniques were performed with fecal slurries homogenized in a fill-FLOTAC device. In the study population, prevalence of strongyle eggs, Eimeria spp. oocysts, Moniezia spp. eggs and Trichuris spp. eggs was 81.4%, 73.9%, 7.5%, and 3.1%, respectively. Counts of strongyle eggs and Eimeria spp. oocysts obtained from 1 to 3 averaged technical replicates of the modified McMaster technique were compared to a single replicate of the Mini-FLOTAC. Correlation between the two techniques increased with an increase in the number of averaged technical replicates of the modified McMaster technique used to calculate EGP/OPG. The correlation for Moniezia spp. EPG when averaged triplicates of the modified McMaster technique were compared to a single replicate of the Mini-FLOTAC count was high; however, the correlation for Trichuris spp. eggs was low. Additionally, we used averaged counts from both techniques to show the overdispersion of parasites in bison herds. Mini-FLOTAC is an acceptable alternative to the McMaster for bison parasites. Increasing technical replicates of McMaster increases correlation with mini-FLOTAC. Gastrointestinal parasites are overdispersed in bison.

Changes in the Serum Protein Fractions in Goats after Treatment of Natural Gastrointestinal Parasite Infections. Vet Med Int 2021; 2021:9946519. [PMID: 34888029 PMCID: PMC8651421 DOI: 10.1155/2021/9946519] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/05/2021] [Accepted: 11/17/2021] [Indexed: 11/18/2022] Open
Abstract
Gastrointestinal parasitic infections in small ruminants belong to major health problems. The regulation of gastrointestinal infections in goats and the responses developed against them appear to be different from those observed in sheep. In the literature, there is a lack of data on the effect of gastrointestinal parasitic infections on the serum protein profile in goats. Therefore, the aim of the study was to determine the electrophoretic pattern of serum proteins in goats naturally infected with gastrointestinal parasites and to compare the changes in the total serum proteins and serum protein fractions (albumin and α1-, α2-, β-, and γ-globulins) obtained after antihelminthic treatment. Eight adult female goats of the white shorthaired breed from a small dairy goat farm at the age ranging between 3 and 5 years with average body weight 35.4 ± 3.2 kg and body condition score (BCS) from 1.5 to 2.5 were used in the study. The serum proteins in goats were separated into five fractions: albumin, α1- and α2-globulins, and β- and γ-globulins. Significant changes after treatment were found in the relative concentrations of albumin (P < 0.01) and α2- (P < 0.05), β- (P < 0.001), and γ-globulins (P < 0.01), as well as albumin/globulin ratio (P < 0.01). The mean concentration of total serum proteins was, after the antiparasitic treatment, significantly higher. Among the globulin fractions, the γ-globulin fraction contributed most significantly to these changes (P < 0.001). The results presented in the study suggest a significant effect of antiparasitic treatment in goats on the synthesis of blood serum proteins and on the changes of the proportion of serum protein fractions.

Abstract
The present study was undertaken to work out the population structure of trichostrongylids affecting the small ruminants of Kashmir valley. The faecal samples were collected from each zone and sector of the valley and were examined by qualitative as well as quantitative techniques for presence of trichostrongyle eggs, followed by coproculture using petridish method for harvesting of infective larvae. The overall prevalence revealed Haemonchus spp. to be the most predominant trichostrongyle worm followed by Trichostrongylus spp., Oesophagostomum spp., Teladorsagia spp., Chabertia spp. and other larvae, the difference being statistically significant. In south Kashmir, a different trend was observed for trichostrongyle worms with predominance of Trichostrongylus spp., followed by Haemonchus spp., Oesophagostomum spp. and other larvae, the difference being statistically significant (P<0.05). Teladorsagia spp. and Chabertia spp. were not recorded in the south Kashmir, while as Oesophagostomum spp. and Chabertia spp. were not recorded in the north Kashmir. In small ruminants of Kashmir valley, predominance of Haemonchus spp. was observed in private sector farms than government sector farms, whereas predominance of Trichostrongylus spp. was observed in government sector farms than private sector farms, and both the difference were statistically significant. Non-significantly Teladorsagia spp. was found more in government sector farms than private sector farms. In government sector farms Oesophagostomum spp. and Chabertia spp. were recorded, while as in private sector farms Oesophagostomum spp. and Chabertia spp. were not recorded. It is concluded that trichostrongylid worms are prevalent throughout Kashmir valley in the small ruminants and appropriate control strategies need to be adopted for their control.

Abstract
Coprological studies on the prevalence of gastrointestinal helminth (GI) parasites in domestic ruminants from Srikakulam district of Andhra Pradesh, India, were carried out for a period of one year from January 2019 to December 2019. Fecal examination was done using direct smear, sedimentation and floatation methods. Altogether 3527 fecal samples were examined including 595 from cows, 485 from buffaloes, 1342 from sheep and 1105 from goat. Out of 3527 fecal samples examined, 1084 were found to be positive with three groups of gastrointestinal parasites (GI) showing an overall prevalence of 30.7%. Maximum infection was noted with nematodes (39.1%) and trematodes (37.3%), least infection was noted with cestodes (3.5%) and mixed infections were found to be moderate (20.01%). Host wise prevalence of parasitic infection has shown highest in the case of cattle recording 43.03%, followed by 40.8% in buffaloes, 29.4% in sheep, and 21.4% in goats. Total six varieties of parasites were recorded, the predominant being Haemonchus (Strongyle group) (29.25%), followed by Paramphistomum (25.5%), Fasciola (11.9%), Strongyloides (7.6%), Moniezia (3.5%) and Trichuris (2.2%). Season wise data on prevalence showed, high rate of infection in summer season (32.0%) when compared to winter (30.2%) and rainy (29.9%) seasons. Further studies are needed to design a rational for sustainable management of GI parasite infections in domestic animals of local regions.

Abstract
AIM This study was conducted to determine the prevalence of gastrointestinal (GI) worms in Wonosobo and thin-tailed sheep from the slope of Mount Sumbing. MATERIALS AND METHODS Fecal samples (n=305) were collected directly from the rectum of Wonosobo and thin-tailed sheep during the dry and rainy seasons in Wonosobo Regency, Central Java Province, Indonesia. The presence of GI helminth eggs in the fecal samples was assessed using the modified McMaster egg counting technique. The identification of the eggs or oocysts was done on the basis of their morphology and size. RESULTS The highest prevalence of GI worms was observed in male thin-tailed sheep (76.47%) during the rainy season, whereas the lowest prevalence was observed in female Wonosobo sheep (47.36%) during the dry season. The types of GI nematodes observed in these two types of sheep were Haemonchus contortus, Ostertagia spp., Trichostrongylus spp., Bunostomumspp., Trichuris spp., and Moniezia spp. The GI worms with the highest prevalence were of Haemonchus spp. and were observed in male thin-tailed sheep. The prevalences of the two types of sheep assessed at an altitude of 1150 m above sea level were higher than those observed at the altitude of 1586 m. The prevalence of clinical and sub-clinical parasites infestation in Wonosobo and thin-tailed sheep in Kwadungan village was significantly different (p<0.05). CONCLUSION This study showed that two types of local sheep on the slope of Mount Sumbing are infected with various GI worms during the dry and rainy seasons. The highest prevalence of GI worms was found in thin-tailed sheep at an altitude of 1150 m above sea level during the rainy season, with H. contortus being the most prevalent GI parasites.

Abstract
Gastrointestinal parasites are important in small ruminant farming because they can impact negatively on the productivity of animals. The objectives of the present study were to estimate the prevalence of gastrointestinal parasites and to assess mortality attributable to gastrointestinal parasite infection in sheep and goats. We collected fecal samples from 114 sheep and 292 goats from 34 farms for coprological examination. In addition, we evaluated necropsy records for sheep and goats that were submitted from 2002 to 2016 to the pathology diagnostic laboratory in the School of Veterinary Medicine at St. George's University, Grenada. Out of 406 small ruminant (292 goat and 114 sheep) fecal samples examined, 385 were positive for gastrointestinal parasites, giving an overall prevalence of 95% (95% confidence interval (CI) 92% to 97%). All the 34 farms visited were found to have positive animals to at least one type of gastrointestinal parasite; 100% herd prevalence (95% CI: 88% to 100%). Among the 292 goat fecal samples examined, 285 were positive for gastrointestinal parasites (98%; 95% CI: 95% to 99%) whereas the proportion of positive fecal samples in sheep was 88% (95% CI: 80% to 93%). There was a significant difference in prevalence of gastrointestinal parasites between sheep and goats (p = .0002). The proportion of infection with coccidia in goats and sheep was 76% and 75%, respectively. For helminthes, the proportions were as follows: Moniezia spp., 14% in goats and 4% in sheep; Strongyloides spp., 36% in goats and 21% in sheep; strongyle type eggs 89% in goats and 66% in sheep. Mixed infections in both sheep and goats were more common (92%) than single ones (8%). Out of 220 necropsy records evaluated, 29% of mortality was due to Haemonchus contortus infection. Moniezia spp and Oesophagostomum spp. were also commonly found.

Abstract
AIM The aim of this study was to explore the prevalence of gastrointestinal parasitism in small ruminants in relation to various risk factors in the western zone of Punjab. MATERIALS AND METHODS During the study, 603 fecal samples (391 of sheep and 212 of goats) were examined qualitatively by floatation and sedimentation techniques, and quantitatively by McMaster technique. RESULTS Out of the 603 fecal (391 sheep and 212 goats) samples examined, 501 were found positive for endoparasitic infection with an overall prevalence of 83.08%, consisting of 85.16% and 79.24% in sheep and goats, respectively. Egg per gram in sheep was apparently more 1441.88±77.72 than goats 1168.57±78.31. The associated risk factors with the prevalence of gastrointestinal tract (GIT) parasites showed that females (85.97%) were significantly more susceptible than males (69.23%). Age wise the adults (>6 months) were significantly more prone to parasitic infection as compared to young ones (<6 months). Seasonal variation was recorded throughout the year and was significantly highest during monsoon (90.10%), followed by winter (83.84%) and summer (78.35%). CONCLUSION The study revealed an overall prevalence of 83.08% of GIT parasitic infections in small ruminants constituting 85.16% in sheep and 79.24% in goats in the western zone of Punjab. The most relevant risk factors for the prevalence of gastrointestinal parasitism in ruminants were sex, age, and season.

Abstract
A longitudinal study was conducted in low-input low-output farming systems to determine the prevalence of gastrointestinal parasitic infections in different age groups, sex and associated risk factors in goats. A total of 580 indigenous goats were randomly selected in areas representing the five agro-ecological regions of Zimbabwe in the dry and wet seasons. Blood and faecal samples were collected from each animal and egg/oocyst per gram of faeces (epg/opg), larval culture, and packed cell volumes (PCV) were determined. Factors affecting parasitic infections were evaluated. Highest prevalence was determined for Eimeria oocysts (43%), strongyles (31%) and lower levels in trematodes and cestodes. Parasites identified were Haemonchus, Strongyloides and Oesophagostomum. Area, season, sex and age significantly influenced patterns of gastrointestinal infections (P < 0.05). Cannonical correlations indicated that parasite species composition varied by area and impacts of risk factors also differed. Risk of infection was very high for goats sampled in Natural regions (NR) I, II, III (OR = 6.6-8.2; P < 0.05) as compared to those in NR IV and V. Highest helminths and Eimeria infections were observed in the wet vs. dry season (P < 0.05). Young animals were more susceptible to parasitic infections (P < 0.05). Prevalence was higher in males than females, with odds of infection for males being almost three times to that for females (P < 0.0001). Knowledge concerning gastrointestinal helminth biology and epidemiological infection patterns caused by these parasites is essential in the development of appropriate control strategies and this has a potential to reduce production losses.

Abstract
Aim: Gastrointestinal (GI) helminth parasitism is one of the major constraints for profitable sheep production. Due to variations in the prevalence of GI helminths from region to region, it becomes important to map out accurately the parasitic fauna of a particular region for development of suitable control measures. Materials and Methods: An extensive study of GI helminths was carried out in Budgam district of Kashmir Valley over a period of 1 year. A total of 1200 fresh ovine faecal samples from both sexes of young ones and adults were collected in sterilized plastic bags and examined by standard sedimentation and floatation techniques. Positive faecal samples (15-20%) in each season were examined by Stoll’s dilution method to determine the parasitic load. A total of 120 faecal samples (30 samples in each season) positive for strongyle eggs were subjected to coproculture using Petridish method and the third stage larvae were harvested to find out prevalence of different genera of strongyle worms. Results: The overall prevalence of GI helminths was found to be 77% with platyhelminths and nemathelminthes in 26.58 and 60.92% animals, respectively. The overall prevalence of mixed GI helminths was found to be 8.67%. Eggs of various helminths encountered in the present study were those of Fasciola spp. (3.58%), Dicrocoelium spp. (11.58%), paramphistomes (4.83%), Moniezia spp. (7.92%), strongyle worms including Nematodirus spp. (57.75%), Strongyloides spp. (1.67%), and Trichuris spp. (1.5%). On coprocultural examination Haemonchus spp. (55%) was found to be most predominant strongyle worm followed by Trichostrongylus spp. (17.5%), Ostertagia spp. (11.67%), Oesophagostomum spp. (9.17%), and Chabertia spp. (6.67%). On seasonal basis, highest prevalence of GI helminths was recorded in summer (83.00%) followed by spring (78.67%), winter (76.33%), and autumn (70.00%), the difference being statistically non-significant (p>0.05). The prevalence of platyhelminths (Fasciola spp., Dicrocoelium spp. and Moniezia spp.) was found to be non-significantly higher in winter, but paramphistomes showed the highest prevalence in the summer season. Nemathelminth infection was found highest in summer season and lowest during the winter season. Eggs per gram (EPG) ranged from 0 to 1800, and an average EPG count was found to be 454.35±27.85. EPG was found to be highest in summer (684.00±69.83) and lowest in winter (202.38±18.82). The overall prevalence of GI helminths was found more in adult sheep (83.00%) compared to young ones (53.11%), the difference being statistically significant (p<0.05). Similarly, the prevalence of helminths was found to be higher in females (78.32%) as compared to males (72.97%), the variation being statistically non-significant (p>0.05). Conclusion: Seasonal variation plays an important role in the prevalence of GI helminths in addition to age and sex of the animal.

[PMID: 27047018 PMCID: PMC4774656 DOI: 10.14202/vetworld.2015.1205-1209] [Citation(s) in RCA: 13] [Impact Index Per Article: 1.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/09/2015] [Revised: 09/08/2015] [Accepted: 09/13/2015] [Indexed: 11/24/2022] Open
Abstract
Aim: The aim of the present study is to assess the prevalence of intestinal and haemoprotozoan parasites of small ruminants (Sheep and Goats) in North Western part of Tamil Nadu, India. Materials and Methods: A total of 630 faecal samples (251-sheep, 379-goats) and 554 blood smears (242-sheep, 312-goats) were examined, for the presence of eggs of intestinal and haemoprotozoan parasites, respectively. The samples were received from the Veterinary college hospital and Veterinary dispensaries in North Western part of Tamil Nadu. Faecal samples were processed by sedimentation technique and examined under low power objective (×10), and blood smears were stained using Giemsa’s technique and examined under oil immersion (×100). Result: The analysis of data on the prevalence of intestinal and haemoprotozoan parasites of sheep and goats in North Western part of Tamil Nadu for the period from 2004 to 2013, showed an overall prevalence of intestinal parasites was found to be 67% and 35% in sheep and goats, respectively, whereas only 11% of sheep and 3% of goats had the haemoprotozoan parasitic infection. Highly, significant difference (p<0.01) in the prevalence of intestinal (χ2=65), and hemoprotozoan (χ2=15.4) parasitism was observed between sheep and goats. Intestinal parasites such as strongyles, Trichuris, Moniezia, amphistome, and coccidia were identified in which the highest prevalence was observed with coccidia, followed by strongyles, Monezia, Trichuris, and least with amphistome in both the sheep and goats. The haemoprotozoan parasites recorded were Theileria and Anaplasma species, of which, Anaplasma spp. being the highest and Theileria spp. the least prevalent in both the sheep and goats. The seasonal prevalence of intestinal parasites showed highest in rainy season, followed by moderate in winter and least with summer in both the sheep and goats, whereas the haemoprotozoan parasites recorded were the highest in summer followed by winter and least with rainy season. Conclusion: The present study suggests that North Western part of Tamil Nadu is highly endemic for intestinal parasites such as coccidia and strongyles and haemoprotozoans such as Anaplasma and Theileria species in small ruminants.
