Prevalence of gastrointestinal parasite in small ruminants of District Dir Upper Khyber Pakhtunkhwa Province of Pakistan

Prevalência de parasita gastrointestinal em pequenos ruminantes do distrito Upper Dir, da província de Khyber Pakhtunkhwa, no Paquistão

Abstract

The present research was planned to assess the occurrence of intestinal parasites in small ruminants of Upper Dir of Khyber Pakhtunkhwa Province of Pakistan. For this purpose, the faecal material was collected randomly with gloved fingers directly from the rectum region of sheep and goats and the faecal materials were then put in hygienic plastic bottles with 10% formalin. The overall 315 (n=184 sheep and n= 131 goats) faecal samples were collected out of 315 samples, 281 were found positive for different parasites. Patterns-wise prevalence of GI parasites of the study area was found. Overall Single parasitism 89.20% (281/315) with 94.0% (173/184) in sheep and 82.43% (108/131) in goats. Double parasitic infection in small ruminant recorded in which Fasciola+ Haemonchus. contortus in sheep were found their prevalence was 25.54% (47/184). While in goats, the double parasitic infection in which Haemonchus contortus+Trichuris spp were found and their prevalence were 23.43% (30/131). The species found in the sample of sheep were includes, i.e., Strongyloides papillosus (41.30%), Heamonchus controtus (21.73%), Trichuris ovis (17.39%), and Fasciola hepatica (13.58%), the corresponding value for goat were Strongyloides spp 33.33% (36/108), Haemonchus spp 28.70%, (27/108), Trichuris spp 25.20% (27/184) and Fasciola spp 10.68% (14/184). The sheep of the study area are more infected as compared to goats. This study suggested that gastrointestinal parasites are major health problems of small ruminants in the study area. Therefore, a comprehensive study on species of gastrointestinal parasites circulating in the area, control options, cost-effective strategies and awareness about gastrointestinal parasites among the farmers in the study area should be instituted.

Resumo

A presente pesquisa foi planejada para avaliar a ocorrência de parasitas intestinais em pequenos ruminantes do distrito Upper Dir, da província de Khyber Pakhtunkhwa, no Paquistão. Para tanto, o material fecal foi coletado aleatoriamente com dedos enluvados diretamente da região do reto de ovelhas e cabras, e os materiais fecais foram colocados em garrafas plásticas higiênicas com formol a 10%. No total, 315 (n = 184 ovelhas e n = 131 cabras) amostras fecais foram coletadas; destas, 281 foram consideradas positivas para diferentes parasitas. A prevalência de padrões de parasitas GI da área de estudo foi encontrada. Parasitismo global único 89,20% (281/315) com 94,0% (173/184) em ovinos e 82,43% (108/131) em cabras. Infecção parasitária dupla em pequenos ruminantes registrada em Fasciola + Haemonchus contortus em ovinos, sua prevalência foi de 25,54% (47/184). Já em caprinos, a dupla infecção parasitária em que Haemonchus contortus + Trichuris spp foram encontrados e sua prevalência foi de 23,43% (30/131). As espécies encontradas na amostra de ovinos foram: Strongyloides papillosus (41,30%), Heamonchus controtus (21,73%), Trichuris ovis (17,39%) e Fasciola hepatica (13,58%), o valor correspondente para cabra foi Strongyloides spp. 33,33% (36/108), Haemonchus spp. 28,70%, (27/108), Trichuris sp 25,20% (27/184) e Fasciola spp. 10,68% (14/184). As ovelhas da área de estudo estão mais infectadas do que as cabras. Este estudo sugeriu que os parasitas gastrointestinais são os principais problemas de saúde dos pequenos ruminantes na área de estudo. Portanto, um estudo abrangente sobre as espécies de parasitas gastrointestinais que circulam na área, opções de controle, estratégias de baixo custo e conscientização sobre parasitas gastrointestinais entre os agricultores na área de estudo deve ser instituído.

1. Introduction

Gastrointestinal parasites cause mortalities, production loss, and weight loss in small ruminants (goats and sheep), thereby impeding their production system. Small ruminants (goat and sheep) constitute a significant portion of livestock in a country (Siddiki et al., 2009SIDDIKI, A.Z., UDDIN, M.B., HASAN, M.B., HOSSAIN, M.F., RAHMAN, M.M., DAS, B.C., SARKER, M.S. and HOSSAIN, M.A., 2009. Coproscopic and haematological approaches to determine the prevalence of helminthiasis and protozoan diseases of Red Chittagong cattle. Pakistan Veterinary Journal, vol. 30, pp. 1-6.). Livestock has greater importance in raising the financial position of a country because livestock is the chief source of protein, and their products like skin, bones, and many goods are made from the fetch of these animals (Gupta et al., 1987GUPTA, R.P., YADAV, C.L. and CHAUDHRI, S.S., 1987. Epidemiology of gastrointestinal nematodes of sheep and goats in Haryana, India. Veterinary Parasitology, vol. 24, no. 1-2, pp. 117-127. http://dx.doi.org/10.1016/0304-4017(87)90136-1. PMid:3590608.
http://dx.doi.org/10.1016/0304-4017(87)9...
). Common abdominal parasites of livestock are coccidia species of phylum protozoa. Trematodes belong to flukes, nematodes commonly called roundworms, cestodes famous on tapeworms, while the most abundant nematodes in small ruminants are Tricho Strongyloides which their prevalence are worldwide (Awraris et al., 2012AWRARIS, T., BOGALE, B. and CHANIE, M., 2012. Occurrence of gastrointestinal nematodes of cattle in and around Gondar town, Amhara regional state, Ethiopia. Acta Parasitologica Globalis, vol. 3, no. 2, pp. 28-33.). Nematodes have a single host life cycle in small or large ruminant’s guts to complete their life cycle (Scott and Sutherland, 2009SCOTT, I. and SUTHERLAND, I., 2009. Gastrointestinal nematodes of sheep and cattle: biology and control. Chichester: Wiley Blackwell.). Nematode’s infections are very significant economically that are the leading agents for poor growth and insufficient production. Livestock are highly susceptible to different infections of these nematodes (Lashari and Tasawar, 2011LASHARI, M.H. and TASAWAR, Z., 2011. Prevalence of some gastrointestinal parasites in sheep in southern Punjab, Pakistan. Pakistan Veterinary Journal, vol. 31, no. 4, pp. 295-298.), Paramphistomiasis, Fascioliasis, Tricho strongylosis, Haemonchosis and oesophagostomiasis GI parasitism can affect the growth and production of livestock (Speedy, 1992SPEEDY, A.W., 1992. Progress in sheep and goat research. Wallingford: CAB International, pp. 179-188.). Haemonchosis cause serious mortalities in sheep and goats also cause significant loses if there is no treatment programmes and appropriate monitoring of parasites (Besier et al., 2016BESIER, R.B., KAHN, L.P., SARGISON, N.D. and VAN WYK, J.A., 2016. Diagnosis, treatment and management of Haemonchus contortus in small ruminants. Advances in Parasitology, vol. 93, pp. 181-238. http://dx.doi.org/10.1016/bs.apar.2016.02.024. PMid:27238006.
http://dx.doi.org/10.1016/bs.apar.2016.0...
). Trematodes are endoparasites that have indirect life cycles with one or more intermediate host’s molluscs (Berra and Au, 1978BERRA, T.M. and AU, R.J., 1978. Incidence of black spot disease in fishes in Cedar Fork Creek, Ohio. The Ohio Journal of Science, vol. 78, no. 6, pp. 318-322.). Parasites of trematodes are universally distributed in ruminants' animals and have attained a high zoological position in the world (Rafique et al., 2009RAFIQUE, A., RANA, S.A., KHAN, H.A. and SOHAIL, A., 2009. Prevalence of some helminths in rodents captured from different city structures including poultry farms and human population of Faisalabad, Pakistan. Pakistan Veterinary Journal, vol. 29, no. 3, pp. 141-144.). The common fluke’s Fasciola hepatica lives in the liver of sheep and causes fascioliasis. Fasciola hepatica intends countless financial harm that are universally discrete classes (Irfanullah et al., 2016IRFANULLAH, NISAR, M.F., JADOON, A.A.K. and TABASSUM, S., 2016. Prevalence of Fasciola hepatica in domesticated cattle of District Karak, Khyber Pakhtunkhwa, Pakistan. Asian Journal of Animal Sciences, vol. 10, pp. 85-91.). Mature trematodes parasitic infection in animals that are the basis to infection in sheep and goats remain dependent on the geographic diversity of chosen class everywhere. Scientific suggestions about trematodes infection clinical symptoms, which are typically happening in hot regions of the biosphere, contain weakness, weight loss, reduce milk manufacture, water-logged, decreasing quality, watery diarrhoea, decrease in the number of products, and even death caused by parasites (Gupta et al., 1987GUPTA, R.P., YADAV, C.L. and CHAUDHRI, S.S., 1987. Epidemiology of gastrointestinal nematodes of sheep and goats in Haryana, India. Veterinary Parasitology, vol. 24, no. 1-2, pp. 117-127. http://dx.doi.org/10.1016/0304-4017(87)90136-1. PMid:3590608.
http://dx.doi.org/10.1016/0304-4017(87)9...
).

No evidence is accessible of parasites of goats and sheep in the present region. This evidence with suggestion is primarily essential for the identification and prevalence of parasitic disease that provides significant understanding for investigation and prevalence of helminthiasis in Dir upper. Therefore, this current research was aimed at examining and the occurrence of the different parasites found in the Gastrointestinal tract of both goat and sheep of Dir upper District of KPK.

2. Methods and Materials

2.1. Study area

The total area of District Upper Dir is 3699 square kilometers. It is situated with latitudes and longitudes of 35° and 71° N, respectively. Geographically upper Dir district is situated on the north side of Pakistan. This district is surrounded in North West by district Chitral, west by Bajwar agency, in the south by district Dir lower, while in the East by Swat district see (Figure 1) Mostly district Dir upper is covered with high mountains and hills. In contrast, there is no plain area in the study region.

Figure 1
Map of Study area Dir Upper KPK Pakistan.

2.2. Study population

The study population consisted of all goats and sheep in the study area.

2.3. Samples collection

Faecal samples were collected from upper Dir districts of the three most populated regions as Wari, Khas Dir, and Sharingal.

2.4. Direct smear methods (wet mount techniques)

2.4.1. Normal saline solution

A solution of the saline wet mount was made in which 2 grams of faces were mixed within the drop of saline upon a glass slide. A light microscope was used for smear examination as described by Urquhart et al. (1987)URQUHART, G.M., ARMOUR, J., DUNCON, J.L., DUNN, A.M. and JENNINGS, F.W., 1987. Veterinary parasitology. Essex: Longman Group, pp. 19 and 276-277..

2.5. Sedimentation technique

The sedimentation technique was used to detect some parasites’ eggs like trematodes eggs are larger than other parasitic eggs; therefore, these eggs settled down quickly in the test tube when centrifuged with a solution of NaCl. After this, a drop of settled down material put on the slides with a drop of NaCl and examined under the microscope at 4x and 10x ranges, respectively.

2.6. Statistical analysis

Statistically, analysis conducted using SPSS 16.0. The comparative occurrence of dissimilar gastrointestinal (GI) parasites class or individuals correspondingly measured as (%) of prevalence = (numbers of +samples/Total numbers of samples studied) x100. The evocative information gotten examined over manifold log deteriorations for the measurement of significance of association determined like age of species sex and ecology of occurrence and gastrointestinal parasites in small ruminants (Sajid et al., 2009SAJID, M.S., IQBAL, Z., KHAN, M.N., MUHAMMAD, G. and KHAN, M.K., 2009. Prevalence and associated risk factors for bovine tick infestation in two districts of lower Punjab, Pakistan. Preventive Veterinary Medicine, vol. 92, no. 4, pp. 386-391. http://dx.doi.org/10.1016/j.prevetmed.2009.09.001. PMid:19782414.
http://dx.doi.org/10.1016/j.prevetmed.20...
).

3. Results

The current study is based on the identification and prevalence of gastrointestinal parasites in small ruminants (goats and sheep) in District Upper Dir. It has not been reported previously by any other author of the mentioned area. Overall, in this present study, 312 (n=184 sheep and n= 131 goats) were collected in Upper Dir Pakistan (Table 1).

4. Discussion

This present research work showed the overall occurrence of the parasite in sheep and goat that were 94.0% (n=173/184 and 89.20% (n=108/131), respectively. Different species of nematodes recovered during this investigation have already been reported by different researchers in different parts of the world (Pedreira et al., 2006PEDREIRA, J., PAZ-SILVA, A., SÁNCHEZ-ANDRADE, R., SUAREZ, J.L., ARIAS, M., LOMBA, C., DÍAZ, P., LÓPEZ, C., DÍEZ-BAÑOS, P. and MORRONDO, P., 2006.

; Nwosu et al., 2007NWOSU, C.O., MADU, P.P. and RICHARDS, W.S., 2007. Prevalence and seasonal changes in the population of gastrointestinal nematodes of small ruminants in the semi-arid zone of north-eastern Nigeria.

The prevalence recorded in the present study is lower than the study conducted by (Gadahi et al., 2009GADAHI, J.A., ARSHED, M.J., ALI, Q., JAVAID, S.B. and SHAH, S.I., 2009. Prevalence of gastrointestinal parasites of sheep and goat in and around Rawalpindi and Islamabad, Pakistan. Veterinary World, vol. 2, no. 2, pp. 51-53.). They reported overall prevalence among the sample from the sheep n=48(53.33%) and n=206(66.45%) from goat were detected positive for GI parasites. Thus the result of the present study is nearly similar to the study conducted by (Singh et al., 2017SINGH, E., KAUR, P., SINGLA, L.D. and BAL, M.S., 2017. Prevalence of gastrointestinal parasitism in small ruminants in western zone of Punjab, India. Veterinary World, vol. 10, no. 1, pp. 61-66. http://dx.doi.org/10.14202/vetworld.2017.61-66. PMid:28246448.
http://dx.doi.org/10.14202/vetworld.2017...
). They reported the prevalence rate of goat 212 (85.16%) while in sheep 391 (79.24%), the occurrence of gastrointestinal parasites tended to be higher in sheep 62 (72%) than in goats 160(63%) (Asif et al., 2008ASIF, M., AZEEM, S., ASIF, S. and NAZIR, S., 2008. Prevalence of gastrointestinal parasites of sheep and goats in and around Rawalpindi and Islamabad, Pakistan. Journal of Veterinary & Animal Sciences, vol. 1, pp. 14-17.).

In risk factor Patterns wise prevalence of GI parasites of the study area was found in overall single parasitism 89.20% (281/315) with 94.0% (173/184) in sheep and 82.43% (108/131) in goat with the occurrence of Strongyloides 41.3% (76/173), Heamonchus spp 24.77% (40/173), Trichuris spp 17.39% (32/173) and Fasciola spp 13.58% (25/173) in sheep while the prevalence of Strongyloides spp 27.48% (36/108), Heamonchus spp 23.39% (33/108), Trichuris spp 21.37% (28/108) and Fasciola spp 8.39% (11/108) in goat were found see (Table 2).

Similarly, a study conducted in various part of the world revealed that the result of the present study is nearly similar to the study conducted by (Gadahi et al., 2009GADAHI, J.A., ARSHED, M.J., ALI, Q., JAVAID, S.B. and SHAH, S.I., 2009. Prevalence of gastrointestinal parasites of sheep and goat in and around Rawalpindi and Islamabad, Pakistan. Veterinary World, vol. 2, no. 2, pp. 51-53.). In their investigation, 53.33% prevalence for sheep and 66.45% prevalence for goat have observed in which most of the sample were positive with multiple infections than single infection 38 (42.22%) and 156 (50.32) in sheep and goats respectively also study conducted by (Raza et al., 2014RAZA, M.A., YOUNAS, M. and SCHLECHT, E., 2014. Prevalence of gastrointestinal helminths in pastoral sheep and goat flocks in the Cholistan desert of Pakistan. The Journal of Animal & Plant Sciences, vol. 24, no. 1, pp. 127-134.) reported their prevalence with significant P value = 0.01 in single infections of parasites.

In the current study, the double parasitic infection rate in goats and sheep was 48.36% (89/184) and 42.18% (54/131) in goats of District Upper Dir KPK Pakistan, with nematodes and protozoa 25.54% (47/184), and Nematodes 22.82% (42/184) in sheep and nematodes-nematodes 23.43%(30/148), and 42.18% (54/131) see (Table 3) in goats respectively.

The present study result of double parasitic infection was nearly similar to the study instigated by Ayaz et al. (2013)AYAZ, M.M., RAZA, M.A., MURTAZA, S. and AKHTAR, S., 2013. Epidemiological survey of helminths of goats in southern Punjab, Pakistan. Tropical Biomedicine, vol. 30, no. 1, pp. 62-71. PMid:23665709. in small ruminants and greater than the study conducted by (Rafiullah et al., 2011RAFIULLAH, T.A., SAJID, A., SHAH, S.R., AHMAD, S. and SHAHID, M., 2011. Prevalence of gastrointestinal tract parasites in cattle of Khyber Pakhtunkhwa. ARPN J Agr Biol Sci, vol. 6, pp. 9-15.). Their investigation reported higher double parasitic infection with a significant P value=0.02. This infection rate is due to the variation present in weather grazing behaviour, and many other risk factors responsible for the prevalence of parasitism in small ruminants discussed earlier.

In the current study, triple parasitic infection in sheep of District Upper Dir were nematodes and protozoan with the prevalence rate of 25.54% (47/184) of species Fasciola spp+ H. contortus + T. ovis. And H. Contortus + Trichuris +Strongyle 26.56% (34/184) and Hemunchus spp+Strongyle spp +Faciola spp = 17.96% (23/131) see (Table 4) in goats. These tipple parasitic infections were also investigated by various researchers in various parts of the world, like 42.225 by (Gadahi et al., 2009GADAHI, J.A., ARSHED, M.J., ALI, Q., JAVAID, S.B. and SHAH, S.I., 2009. Prevalence of gastrointestinal parasites of sheep and goat in and around Rawalpindi and Islamabad, Pakistan. Veterinary World, vol. 2, no. 2, pp. 51-53.), who reported the prevalence of parasitic infections in small ruminants of the species Trichurus spp+Coccidia spp and Haemonchus spp.
