“…The ability of pre-parasitic stages to survive in the environment directly influences the level of infection (Gupta et al, 1987). Therefore, in dry areas, humidity is the most important parameter that influences larval development (Chiejina and Fakae, 1984;Tarazona et al, 1985;Uriarte and Gruner, 1989), so that the worm burden is of minor intensity compared with wet areas where larval stages are more influenced by temperature (Michel, 1969).…”

A total of 322 gastrointestinal tracts were examined from traditionally reared goats originating from a dry area of central Spain. A large spectrum of gastrointestinal nematodes was observed, Teladorsagia circumcincta and T. trifurcata being the most prevalent species, followed by Trichostrongylus vitrinus and Nematodirus filicollis. Trichostrongylus capricola recorded a high level of infection despite low prevalence. A nematode infection rate of 93 % and an average burden of over 3000 worms indicates the highly prevalent infection in Spanish goats. The seasonal pattern shows a real risk of infection all year round, with two peaks in the summer and autumn. Females were more frequently infected than males.

“…It is reported that Gastrothylax crumenifer, Paramphistomum cervi, and Paramphistomum epiclitum are common in ruminants in some regions (Gupta et al 1987;Panyarachun et al 2013;Wang et al 2006). G. crumenifer is an important member of paramphistomes parasitizing the rumen and/or reticulum of ruminants.…”

In the present study, we sequenced and analyzed the mitochondrial (mt) genome of Gastrothylax crumenifer and compared it with other selected trematodes. The full mt genome of G. crumenifer was amplified, sequenced, assembled, analyzed and then subjected to phylogenetic analysis. The complete mt genome of G. crumenifer is 14,801 bp in length and contains two rRNA genes, two non-coding regions (LNR and SNR), 12 protein-coding genes, and 22 transfer RNA genes. The gene organization of the G. crumenifer mt genome is the same as that of other trematodes, except for Schistosoma haematobium and Schistosoma spindale. All the genes are transcribed in the same direction and rich in "A + T", which is in accordance with other trematodes, such as Fasciola hepatica, Paramphistomum cervi, and Fischoederius elongatus. Phylogenetic analysis using concatenated amino acid sequences of the 12 protein-coding genes showed that G. crumenifer is closely related to F. elongatus. The availability of mt genome sequence of G. crumenifer can provide useful DNA markers for studying the molecular epidemiology and population genetics of this parasite and other paramphistomes.

“…Therefore, several workers conducted epidemiological studies on gastrointestinal parasitic infections in different species of domestic animals inhabiting different ecological conditions and geographical provinces. Seasonal occurrence and variable prevalence rate (39.34-92.4 %) of these parasitic infections have been reported from different states of India as Andhra Pradesh (Sreedhar et al 2009), Chhattisgarh (Pathak andPal 2008), Haryana (Gupta et al 1987), Jammu and Kashmir (Mir et al 2008;Tariq et al 2010;Khajuria et al 2012;Lone et al 2012), Karnataka (Murleedharan 2005, Maharashtra (Maske et al 1990;Chavhan et al 2008;Sutar et al 2010;Padwal et al 2011), Meghalaya (Bandyopadhyay et al 2010a, Punjab , Sikkim (Rahman et al 2012) and Uttar Pradesh Sultana 2003, 2009). From the state of Rajasthan such studies or reports are too scanty especially in tribal region of southern Rajasthan.…”

A total of 415 adult domesticated ruminants, 130 cattle (Bos taurus), 108 buffaloes (Bubalus bubalis), 94 goats (Capra hircus) and 83 sheep (Ovis aries) inhabiting tribal rural areas of southern Rajasthan, India were investigated for evidence of gastrointestinal protozoan and helminthic infections. In southern Rajasthan humid ecosystem is predominant and has number of perennial freshwater bodies. Fresh faecal samples of these animals were examined microscopically by direct wet smear with saline and 1 % Lugol's iodine and formalin ether concentration. Of these 296 (71.32 %) were found to be infected with different species of gastrointestinal parasites. The highest (93.84 %) prevalence of these parasitic infections was found in cattle followed by goats (82.97 %), sheep (55.42 %) and buffaloes (46.29 %). Except cattle no other ruminants revealed protozoan infection. A total 8 species of gastrointestinal parasites were encountered. Among these parasites Fasciola hepatica was the commonest (15.18 %) followed by Haemonchus contortus (11.32 %), Ancylostoma duodenale (10.36 %), Trichuris trichiura (9.15 %), Amphistome species (7.95 %), Moniezia expansa (6.98 %), Strongyloides stercoralis (4.57 %) and Balantidium coli (3.37 %). The prevalence rate of these parasitic infections also varied seasonally. The highest prevalence rate was found in rainy season (84.21 %) followed by winter (73.9 %) and summer (52.8 %). The possible causes for variation in prevalence of parasitic infections are also discussed.
