Equines are affected by a large number of endoparasites, these can cause gastrointestinal signs, respiratory, poor performance, slow growth and even cause sudden death. They are prone to Gasterophilus infections because the pastures where they graze are contaminated with infective stages (eggs and larvae) of Gasterophilus, resulting in continuous infestation and re-infestation. The parasite is unique among equine helminths in having three possible routes of transmission: lactogenic, oral, and percutaneous. ROUTE OF ADMINISTRATION AND HOW TO USE: Orally, over the animal tongue, inside the mouth which must be without any food Therapeutic Dose: 200 mcg of Ivermectin + 6.6 mg of Base Pirantel / kg of body weight.
Gasterophilus intestinalis, also known as horse bot fly, is a species of insect of the family Oestridae, and is found worldwide. Previous study has shown that the high prevalence and intensity restricted the wild process seriously. It is well known that botflies are considered as relatively stenothermal parasites and matured females need warm, sunny, and windless weather. Scanning electron photomicrographs of eggs are used to illustrate differences among the eight Gasterophilus species. The horse botfly (Gasterophilus spp.) may cause restlessness and stamping as the flies hover and lay eggs on the hair of the horse's lower limbs and head.Dermatobia hominis, the human botfly, may infest horses in Central and South America.
the Gasterophilus spp., and most of the investigations are centered on the analysis of the total IgG dynamics. The maggots do not live within the animal’s intestines but instead develop from eggs laid by free-living adult flies after the feces have been passed.
But unprotected young foals are at risk of suffering severe damage and even death after massive infections. Form and disposition of the hooks are species specific and are used for species determination. USE OF SYRINGE: Determine the weight of the horse and dial the correct setting on the plunger, having the side of the wheel nearest the barrel on the desired mark.
The eggs of Gasterophilus intestinalis on the hairs of front legs are far removed from their destination and depend on direct assistance from the horse to find their way into the mouth. Life Cycle: Adult Hypoderma, known also as heel flies or gad flies, are ~15 mm long, hairy, and bee-like in appearance. BOTS IN HORSES Bot flies are medium to large brown striped insects, 10-20mm long, a bit like a scrawny wasp or drone bee with a single pair of wings.
Refer to the manufacturer's label for directions for use and cautions for trichlorfon. DOSAGE AND ADMINISTRATION: This syringe contains sufficient paste to treat one 1250 lb horse at the recommended dose rate of 91 mcg ivermectin per lb (200 mcg/kg) body weight. Flies lay their eggs on horses around the chin, mouth, lips, shoulders and forelegs depending on the species. However, little information is available on the genetic variation of Gasterophilus spp. and Gasterophilus spp.6 Lesions characteristically develop where the skin comes into contact with the ground, namely feet, buttocks and trunk. Dosage and Administration: This syringe contains sufﬁcient paste to treat one 1250 lb horse at the recommended dose rate of 91 mcg ivermectin per lb (200 mcg/kg) body weight. An overview on important endoparasites, their vectors, distribution, and disease symptoms is given in Table 1 [4,5] in order to understand the challenge which we are faced worldwide.
SAFETY DIRECTIONS: Poisonous if swallowed.May irritate the eyes.
The adults, which have a bumblebee-like appearance, are prominently active in the summer. nasalis were found, but there was a distinct seasonal variation in their abundance. infection in horses from south-eastern, central, and the north-eastern part of Poland (7, 26). Dosage and Administration Administer orally as a single dose rate to horses at the recommended dose level of 0.2mg ivermectin per kilogram of bodyweight. The presence of parasites can be associated with various factors related to the animal and environmental or geographical factors. Each syringe delivers 120 mg ivermectin, sufficient to treat 600 kg of bodyweight.

These bots larvae can create a mild to moderate gastritis and ulceration of the stomach, causing pain when eating. Gasterophilus spp External Parasites: scabies acari and lice DOSAGE 200 mcg of ivermectin per each kilogram Syringe contains 14 g of ivermectin to 1%, which is enough to treat a 700 kg horse, or 1 g per every 50 kg. Our report documents the clinical and patho- logical features of external ophthalmomyiasis caused by Gasterophilus spp. 26 second stage larvae (L2) and 192 third stage larvae (L3) were collected from infested equines. Infectious Diseases of the Horse: Diagnosis, Pathology, Management, and Public Health A clinician and a pathologist have collaborated to produce this thorough and balanced account of infectious diseases affecting horses. INDICATIONS:Consult your veterinarian for assistance in the diagnosis, treatment, and control of parasitism.
Routine carbon disulfide cautions must be observed • Determine the weight of the horse and dial the correct setting on the plunger. The stomach bot (Gasterophilus spp.) is the larvae of the bot fly and is generally considered to be of little clinical significance. Nevertheless, in this region some aspects concerning the chronobiology of this important myasis caused by Gasterophilus spp. A Pathogenetic Study of Medial Hypertrophy and Hyperplasia of Pulmonary Vessels in the Cat. An average of 45% of horses become infected with gasterophilus spp every year, usually in the summer months to be hatched in the winter. are obligate parasites that infest the gastrointestinal tracts of equids, affecting the horses’ health by absorbing nutrients and secreting toxins [15, 19]. DOSAGE AND ADmINISTrATION Administer orally as a single dose rate to horses at the recommended dose level of 0.2mg ivermectin per kilogram of bodyweight. Introduction Emerged Parasitology 2015 7 Copulation Egg Spawn Find hosts Find mates .
L2 and L3 were collected from the pyloric portion of the stomach of horses originating from two farms located in the District of the Swiss Jura; Delémont: N 47°21'; E 7°20', Switzerland. In Florida 2 species of adult bot flies may be active through-out the year, although they are more abundant from late spring to early winter. Since the early 1900s until presently (2015), more than 25 products have become commercially avail-able for control of endoparasites in horses. When found, the point of fixation (cardia, non-glandular region, glandular region, pilorum-duodenum) was registered and the sample was collected and stored individually.
This larva was embedded deep within the muscularis and the submucosa.
Eggs Tree squirrel bot fly eggs are off-white and oblong, about 1.5 mm long, and resemble tiny grains of rice. The eyes, esophagus, lungs, rumen, and feces were examined from the cattle, and the small intestine was scrutinized from the horses. The presence in some regions of southern Europe of an unusually large number of different species of bot fly suggests a high degree of oestrid biodiversity in this area.
Order and Family: Diptera, Oestridae Size and Appearance: Length (mm) Appearance Egg 1.27-1.5mm Variable depending on species Grayish-yellow to off white. The pupae are known to be sensitive to frost, moisture and flooding, so the environmental conditions present play a significant role in the success of the parasite. Dosage and administration Administer orally as a single dose rate to horses at the recommended dose level of 0.2 mg ivermectin per kilogram of bodyweight. Under conditions of continued exposure to parasites, retreatment may be needed after 4-6 weeks. A parasitologic survey for internal parasites was done at routine necropsy of cattle (N = 142) and horses (N = 190, including 1 donkey) at the Livestock Disease Diagnostic Center, University of Kentucky, in 2000 and 2001. The tongue, pharynx, oesophagus and gums are examined for larvae of Gasterophilus spp., and the nose and sinuses for oestrid larvae. Females lay large numbers of eggs on the host near open wounds or body orifices (sites of castration or the umbilicus are common locations).
Strongyloides westeri is an intestinal threadworm commonly infecting young foals, and it has been associated with small intestinal enteritis, resulting in diarrhea.The pathogenicity of the parasite remains unclear, however. The presence of this myiasis is commonly diagnosis by at the slaughter of the horses, or even when L3 instars are observed in the rectum or they are passed by feces . It is recommended to treat with a boticide at least once a year in the late fall or early winter to decrease the transmission next year.Currently only ivermectin or moxidectin are effective against bots. As tapeworm infestation is unlikely to occur in horses before two months of age, treatment of foals below this age is not considered necessary. The syringe 6.84 g has 6 marks, each mark measure product for 100 kg of body weight.
