“…In agreement with our findings, high prevalences were found in England (63-100 %; Coles and Pearson 2000), Australia (81 %; Bucknell et al 1995), and Saudi Arabia (86.6 %; Anazi and Alyousif 2011). Conversely, lower prevalences were found in the most part of European Countries, such as Swisse (65 %; Brocard and Pfister 1991), France (2-34 %; Bernard et al 1994), Poland (40-47 %;Gawor 1995;Niedźwiedź et al 2013), Sweden (9.9 %; Höglund et al 1997), Belgium (58 %; Agneessens et al 1998), and Germany (2.8 %; Rehbein et al 2013), and in Countries outside Europe, such as the USA (14 %; Lyons et al 2000), Brazil (17-32 %; Sequeira et al 2001;Felix et al 2007), and Turkey (9.8 %; Gökçen et al 2008).

“…Felix et al (2007) found that males were more parasitized than females, whereas Agneessens et al (1998) and Niedźwiedź et al (2013) found that mares were more frequently infected than stallions and geldings. However, according to Agneessens et al (1998), the difference between genders is not likely to be genetically determined, but it may be a reflection of different management conditions. Bucknell et al (1995) found that G. nasalis was less prevalent in horses under 2 years of age than in older ones, whereas they did not found a difference for G. intestinalis prevalence.…”

Gasterophilus larvae are common obligate parasites of the digestive tract of the equids. Horses become infected with this parasite by ingesting the larvae hatched from eggs laid by the female flies. In this study carried out monthly, we (i) counted the Gasterophilus eggs deposited by female flies on the coat of 30 grazing horses, (ii) counted and identified the Gasterophilus larvae retrieved from the digestive tract of 128 slaughtered horses, and (iii) compared these results to meteorological data. Eggs were deposited on all monitored horses, and were present from October to January and from May to September, whereas they were absent from February to April. The number of laid eggs was significantly different between the months, body regions, genders, and age classes (p < 0.05). Larvae were recovered in 112 (87.5%) horses, and 6 species of Gasterophilus were identified. The prevailing species were Gasterophilus intestinalis (recovered in 110 horses; 85.9%) and Gasterophilus nasalis (69 horses; 53.9 %), recovered in all months. Gasterophilus inermis (5 horses; 3.9%), Gasterophilus pecorum (3 horses; 2.3%), Gasterophilus haemorrhoidalis (3 horses; 2.3%)¸ and Gasterophilus meridionalis (2 horses; 1.6%) larvae were also found. Significant differences were found among monthly larval burdens for both Gasterophilus spp. and G. intestinalis (p < 0.05), but not for G. nasalis (p > 0.05). Larval burdens and prevalences did not differed significantly between both genders and age classes (p > 0.05). Monthly eggs and larvae trends were not significantly correlated (p > 0.05). With regard to the meteorological variables, minimum air temperature was significantly correlated with the eggs trend (rho = 1.000; p < 0.001) and maximum air temperature with the Gasterophilus spp. (rho = 0.972; p < 0.001) and G. intestinalis (rho = 0.972; p < 0.001) larvae trends. In addition, the number of hours with a temperature below +10 °C was significantly correlated with G. intestinalis larvae trend (rho = 0.602; p < 0.05). Our findings confirmed that in Sardinia, Gasterophilosis is an important parasitosis in the horses, and it needs more attention and extensive and/or correct treatment to reduce its prevalence.

Prevalence and intensity of gastrointestinal parasites were studied through a longitudinal survey in 400 horses over a 17-month period in an abattoir in Germany. Three hundred and ten horses (77.5 %) were demonstrated harbouring endoparasites either by direct recovery of parasites from the digestive tract and/or in terms of faecal egg counts (strongyles). The following parasites were found (percentage prevalence, range of counts): Gasterophilus intestinalis larvae (2.25 %, 1-154), Gasterophilus nasalis larvae (0.25 %, 44), Trichostrongylus axei (11.0 %, 1-3,620), Habronema majus (8.0 %; 1-422), Habronema muscae (26.5 %, 1-3,563), Habronema spp. fourth-stage larvae (5.5 %; 1-1,365), Parascaris equorum (total prevalence 11.3 %; adults 8.8 %, 1-178; fourth-stage larvae 2.5 %, 5-2,320), Anoplocephala perfoliata (28.5 %, 1-2,013) and Paranoplocephala mamillana (1.0 %, 1-11). Strongyle eggs (≥10 eggs per gram of faeces) were recorded in 60.8 % of the horses (10-6,450 eggs per gram of faeces).Prevalences of infection with T. axei, P. equorum and strongyles did not show a correlation to specific seasons. In contrast, a significant variation among seasons of collection was shown for the infection rates of Habronema spp. (p < 0.05) and A. perfoliata (p < 0.001). Seasonal prevalence of Habronema spp. infection was significantly (p < 0.01) higher in summer (39.0 %), autumn (34.8 %) and winter (36.5 %) than in spring (18.7 %), and A. perfoliata were significantly (p < 0.001) more often recorded during autumn (36.1 %) and winter (36.5 %) than in spring (17.3 %) and summer (15.9 %). Prevalences of T. axei, Habronema spp., strongyles and A. perfoliata in male and female horses were almost alike, but ascarids were significantly (p = 0.025) more often recorded in male than in female horses.
