Abstract
Amprolium (AMP) is an organic compound used as a poultry anticoccidiostat. The aim of this work is to repurpose AMP to control the land snail, Eobania vermiculata in the laboratory and in the field. When snails treated with ½ LC₅₀ of AMP, the levels of alkaline phosphatase (ALP), total lipids (TL), urea, creatinine, malondialdehyde (MDA), catalase (CAT), and nitric oxide (NO) were significantly increased, whereas the levels of acetylcholinesterase (AChE), total protein (TP), and glutathione (GSH) decreased. It also induced histopathological and ultrastructural changes in the digestive gland, hermaphrodite gland, kidney, mucus gland, and cerebral ganglion. Furthermore, scanning electron micrographs revealed various damages in the tegumental structures of the mantle-foot region of E. vermiculata snails. The field application demonstrated that the AMP spray caused reduced percentages in snail population of 75 and 84% after 7 and 14 days of treatment. In conclusion, because AMP disrupts the biology and physiology of the land snail, E. vermiculata, it can be used as an effective molluscicide.

Abstract
Development of anticoccidial resistance and concerns of drug residues have prompted the evaluation of alternatives to allopathic drugs. In current study, anticoccidial effect of amprolium was compared with that of Curcuma longa and Zingiber officinale. Ninety (90) sheep, naturally infected with Eimeria spp. and having a minimum oocyst per gram (OPG) count of faeces above 5000 were randomly selected and divided into six groups of 15 animals each. Animals were supplemented with amprolium @ 62.50 mg/kg body weight (bw) (GI), turmeric @ 200 and 300 mg/kg bw (GII and GIII) and ginger @ 200 and 300 mg/kg bw (GIV and GV), orally for 7 days and GVI animals were kept as untreated infected control. Faecal samples were collected on '0' day before treatment and on 8th, 14th, 21st and 28th day after starting treatment and evaluated using Faecal oocyst count reduction test (FOCRT). The efficacy of amprolium was 93.18%, 96.82%, 95.56% and 95.80% on 8th, 14th, 21st and 28th day, after starting treatment. Turmeric @200 mg/kg b.w. showed efficacy of 41.49%, 52.37%, 61.47% and 60.08% and turmeric @ 300 mg/kg bw was 44.92%, 54.32%, 64.21% and 61.95% effective on 8th, 14th, 21st and 28th day, respectively. Ginger @200 mg/kg bw showed efficacy of 38.51%, 53.48%, 55.38% and 55.53% and ginger @ 300 mg/kg bw was 39.65%, 54.81%, 57.18% and 58.22% effective on 8th,14th, 21st and 28th day, respectively. The results justify use of amprolium for clinical coccidiosis while Curcuma longa and Gingiber officinale could be used as natural prophylactic alternatives.

Abstract
Enteromyxum leei is an enteric myxozoan parasite of fish. This myxozoan has low host specificity and is the causative agent of myxozoan emaciation disease, known for heavy mortalities and significant financial losses within Mediterranean, Red Sea, and Asian aquaculture industries. The disease has rarely been documented within public aquaria and, to our knowledge, has never been confirmed within the USA. This case report describes an outbreak of E. leei in a population of mixed-species east African/Indo-Pacific marine fish undergoing quarantine at a public aquarium within the USA. Four of 16 different species of fish in the population, each of a different taxonomic family, were confirmed infected by the myxozoan through cloacal flush or intestinal wet mount cytology at necropsy. Clinical and histopathological findings in this case are similar to previous findings describing myxozoan emaciation disease, e.g. severe emaciation, cachexia, enteritis, and death. Sequence analysis of the 18S rDNA of intestinal samples from a powder blue tang Acanthurus leucosternon and an emperor angelfish Pomacanthus imperator confirmed the parasite to have 99-100% identity with other E. leei sequences. Spore morphology and ultrastructure were consistent with previous reports of E. leei. Treatment of clinically affected fish by oral administration of the coccidiostats amprolium and salinomycin led to reduction of mortalities and resolution of clinical signs. This case report highlights the importance of thorough examination and surveillance of fish during quarantine, particularly with respect to enteric myxozoans.

Abstract
Coccidiosis is one of the most economically important diseases of poultry. This study determined the preponderance of chicken Eimeria in southern Nigeria and assessed the parasite's resistance to three anticoccidial drugs: Amprolium hydrochloride; Amprolium hydrochloride + Sulfaquinoxaline-Sodium; and Toltrazuril. Multiplex PCR amplification of the SCAR region was used to confirm Eimeria preponderance. Resistance was assessed following the inoculation of 2.32 × 105 infective oocysts into broilers. Data on weight gain, feed intake, feed conversion and fecal oocyst shed were recorded. At 7 days post inoculation 9 birds per treatment were sacrificed and assessed for macroscopic lesions in four intestinal regions. Percent optimum anticoccidial activity (POAA), Anticoccidial index (ACI) and Anticoccidial sensitivity test (AST) were used to access resistance. The preponderance of Eimeria spp. were E. tenella (77%), E. necatrix (55%), E. acervulina (44%) and E. mitis (11%), with multi-species infection occurring in 55% of samples assessed. Fecal oocyst shedding was low (P < 0.05) in the medicated groups. Lesions in the cecal region were present in all infected groups regardless of treatment and accounted for 27.8% of lesion scores by severity and 37.5% of lesion scores by frequency. Overall, lesion scores were less (P < 0.05) in birds of the medicated groups compared with the infected-unmedicated group. The high preponderance of E. tenella in the field, and the occurrence of cecal lesions - caused mainly by E. tenella- despite drug administration, indicate resistance in populations of this species in our isolate. Based-on the POAA, ACI and AST values, the Eimeria isolate showed reduced sensitivity to toltrazuril.

Abstract
Eimeria sp. is a host-specific intracellular parasite that mostly affects young animals. This parasite causes great economic losses in livestock sector. A 6 weeks old calf was brought to Referral Veterinary Polyclinic, ICAR-Indian Veterinary Research Institute, Izatnagar with the history of inappetance and passage of foul smelling diarrhoeic feces rich in occult blood and mucous for the last 3 days. On clinical examination, calf was found to be present in lateral recumbency and showed severe tenesmus, prolapsed rectal mucosa along with small quantity of blood mixed feces sticking to the perineum and tail regions. Diagnosis was done based on clinical observations and fecal examination which showed oocysts of Eimeria sp. The prolapsed rectal mucosa was corrected aseptically by manual procedure. The calf was treated with a combination of sulfadimidine and amprolium along with supportive therapy. The calf recovered clinically after 5 days of therapy and further fecal examination showed no evidence of oocysts of Eimeria sp.

Abstract
This trial was undertaken with the objective to evaluate the efficacy of amprolium, toltrazuril and their combination in rabbits naturally infected with Eimeria species (32 × 103 ± 4.63 oocysts per gram (OPG) of faeces). Thirty-six rabbits (11 weeks old with average body weight (BW) 2000 ± 75 g), were randomly allocated into six groups (six kits each), namely, negative untreated and was retained as negative control (group 1), infected and kept untreated (group 2), treated with single oral dose of amprolium at 50 mg/kg BW for 5 days (group 3), received toltrazuril at 5 mg/kg BW for 2 days (group 4), treated orally with toltrazuril at 2.5 mg/kg BW, two doses with 5 day interval (group 5) and given oral doses of both amprolium and toltrazuril at 50 mg and 5 mg/kg BW (group 6), respectively. Clinical signs, mortalities, production data (feed consumption, feed conversion rate, BW, body weight gain (BWG), and performance index (PI)), OPG of faeces and the percentage of OPG reduction were recorded. The results indicated that both toltrazuril, amprolium and their concurrent use significantly (P<0.05) reduced OPG and effectively controlled coccidiosis related mortality, fully abolished the clinical signs, improved feed consumption, BW, weight gain and feed conversion rate. From the observations of the present study it can be concluded that the oral administration of both drugs and their combined use ameliorated the adverse impacts of intestinal coccidiosis in rabbits as therapeutic, but the concurrent use of both drugs was more superior.

Abstract
Despite the advent of anticoccidial drugs and vaccines, coccidiosis continues to result in substantial economic losses to the poultry industry. Berberine, a natural alkaloid is well known in studies involving synergistic approaches, thereby reducing the dosage of principal drugs. Therefore, a study was designed to see whether a synergistic anticoccidial effect could be obtained between amprolium and berberine, in vivo using broiler chicken. Anticoccidial activity was measured in comparison to the reference drug amprolium on the basis of oocyst output reduction, mean weight gain and feed conversion ratio. Oocyst output was measured using Mc-Masters counting technique. Different combinations of berberine and amprolium were tested and out of which 1:1 ratio was the most effective for controlling these parasites. Oral gavaging of 100(50 + 50) mg/kg body weight of 1:1 ratio of amprolium and berberine caused the equivalent reduction in number of oocysts (38.85 ± 9.61) one day prior to that of standard drug amprolium (49.95 ± 16.65) as well as pure berberine (44.4 ± 9.61) used in the study. Weight gain of birds was also highest in the synergistic group (1547.43 ± 12.86) among all the infected groups. Besides feed conversion ratio in the synergistic group was also better (1.387 ± 0.026). The results of this study proved the effectiveness of both amprolium and berberine and revealed synergism between amprolium and berberine against coccidian oocysts, confirmed by significant reduction in the number of coccidian oocysts shed in the feces, leading to better weight gain and improved feed conversion ratio. The study deep-rooted the synergistic potential of berberine, a natural bioactive compound for controlling a protozoan parasite and the results of this study corroborate with its use for treatment of severe diarrhoea, amoebiasis and intestinal infections.

Abstract
Two sensitive and selective spectrofluorimetric methods are proposed to determine ethopabate (ETH) and amprolium hydrochloride (AMP). First derivative synchronous spectrofluorimetry determines the natively fluorescent ethopabate at 288 nm in presence of amprolium hydrochloride which is a non fluorescent quaternary compound with average recovery 100.54±0.721 over a concentration range of 0.01-0.8 μg/mL. Limits of detection (LOD) and quantification (LOQ) are 0.002 and 0.007 μg/mL, respectively. The second method is direct synchronous spectrofluorimetry for determining amprolium hydrochloride at 362 nm after a reaction with 5% NaOH and 0.08% potassium ferricyanide that is optimized by a two-level factorial design. This method is linear over a concentration range of 0.01-0.65 μg/mL with average recovery 99.4±1.28. Limits of detection (LOD) and quantification (LOQ) are 0.002 and 0.006 μg/mL, respectively. The proposed methods are found to be valid and applicable for the analysis of ETH and AMP in their veterinary formulation. They are successfully applied to determine the studied drugs in chicken plasma and their residues in chicken muscle, liver, egg and chicken-based baby food product with recoveries in the ranges of 95.71-108.73% and 97.36-111.89% and for ETH and AMP, respectively.

Abstract
Various anti-protozoal dugs have been popularly used in the treatment of goat coccidiosis; however, residual effects are well noticed in host animals. The present study was undertaken with the objective to evaluate the anticoccidial efficacy of Artemisia absinthium, as a safe alternative in comparison to two conventional anticoccidial drugs (toltrazuril and amprolium) in goats (Capra hircus) naturally infected with Eimeria spp. (>5,000 oocyst per gram of faeces). Goat kids (1-3 month old, 10 kg body weight) were randomly allocated into five groups (eight kids each). Group A was negative for coccidiosis and was retained as uninfected and untreated (negative control). Group B was infected and was kept untreated (positive control). Group C was given a single oral dose of toltrazuril (Baycox 5 %) at 20 mg kg(-1) BW (IM). Group D received amprolium soluble powder 20 w/w% at 50 mg kg(-1) BW 5 days daily. Group E was given a single dose of ethanolic extract of Artemisia absinthium at 2 g kg(-1) BW. Clinical signs, body-weight gain (BWG) and number of oocysts per gram faeces (OPG) were monitored daily for 30 days post treatment (DPT). The OPG was highly reduced as early as 7 DPT and there was a marked improvement in body weight gain (7 DPT) and faster clinical recovery (3-6 DPT) in the toltrazuril treated kids compared to amprolium and Artemisia absinthium treated groups (P ≤ 0.05). In Artemisia absinthium treated kids, the oocysts continued to be in faeces up to 28th day post treatment indicating that ethanolic extract of herb was less efficacious against caprine coccidiosis as compared to amprolium and toltrazuril. From the observations of the present study it can be concluded that control of goat coccidiosis through single treatment of toltrazuril was highly effective as compared to the other two treatments. However, integrated control involving pasture management, chemical and herbal control will be a more realistic and sustainable means of controlling coccidiosis in goats. Further studies at different doses and concentrations using different solvent preparations of the plant extract are recommended to arrive at a certain conclusion about the anti-coccidial efficacy of Artemisia absinthium, which has been reported to be highly effective against other parasites in ruminants.
