Abstract
Bovine tropical theileriosis caused by Theileria annulata, is a serious constraint to Indian dairy industry with more fatal infections in exotic cattle and substantial losses to cross-bred and indigenous zebu cattle. The present communication is to place on record the first report of molecular based confirmed case of cerebral theileriosis caused by T. annulata coupled with its morphological detection, clinical manifestations, haematological alterations and therapeutic management in a cross bred cattle calf from India. After preparation of peripheral thin blood smear from cross bred cattle calf at the site of collection and fixation with methanol, blood sample brought to Department of Veterinary Parasitology, College of Veterinary Science and A.H, Jabalpur and stained by standard protocol for Giemsa staining. Genomic DNA was isolated from the collected blood sample using QIAamp® DNA blood mini kit following the manufacturer's recommendations and PCR was performed. The cross bred cow calf revealed high rise in temperature (105.5°F), increased heart rate, labored breathing with seromucous nasal discharge, enlargement of prescapular lymph node and animal exhibited tonic clonic convulsions in response to any sudden noise. Giemsa stained thin blood smear revealed intraerythrocytic piroplasm and Koch'sblue bodies of T. annulata within the cytoplasm of lymphocytes. The species of Theileria was confirmed by molecular amplification of genomic DNA as T. annulata.

Abstract
BACKGROUND Cryptosporidium, an opportunistic, zoonotic, apicomplexan parasite, is one of the most common causes of diarrhea in neonatal bovine calves around the globe. Bovine calves act as a major source of infection by excreting huge numbers of highly resistant oocysts in faeces, which can survive for a long time in extreme environmental conditions. As low as ten oocysts can cause disease and mortality, leading to the requirement of an early and accurate diagnosis for proper and favorable prognosis, management, and control. AIMS The current study was conducted with the objective to evaluate various diagnostic techniques (acid fast staining, negative staining, fluorescent, ELISA, PCR, nested PCR, and qPCR) for the detection of Cryptosporidium in the faecal samples of diarrheic bovine calves. METHODS Two hundred diarrheic faecal samples from bovine calves were collected and subjected to these techniques for Cryptosporidium diagnosis. Results of these were evaluated for diagnostic comparison. RESULTS Out of 200 faecal samples evaluated, 24% (48/200) were detected positive for Cryptosporidium using a combination of two techniques as gold standard criteria. Cohen's kappa value indicated moderate to almost perfect agreement (0.616 to 0.986) among all the techniques used in the present study. Leishman staining showed the lowest sensitivity (54.17%), while nested PCR and qPCR showed the highest sensitivity (97.92%). Diagnostic specificity of all these tests ranged from 98.68 to 100%. CONCLUSION Auramine stain was used for the first time in the bovine calves in India for the detection and diagnostic comparison of Cryptosporidium. It showed strong agreement with the molecular as well as classical diagnostic techniques, and can be used for primary screening for better diagnosis.

Abstract
Bovine tropical theileriosis caused by Theileria annulata is an overwhelming haemoprotozoan tick-borne disease in taurine and cross-bred cattle in Punjab, India. However, there seems to be no report from India of cutaneous nodules associated with the disease. This report describes a five-year-old cross-bred cow presented to a university clinic with a history of fever, inappetence and malaise for the past six to seven days. Clinical examination revealed normal vital parameters, pale mucous membranes, mild enlargement of the prescapular lymph nodes and multiple subcutaneous nodular masses (2-4 cm) on the neck and abdomen. Haematology revealed mild anaemia and leucopenia with 48% neutrophils, 48% lymphocytes and 4% eosinophils. Romanowsky-stained smears of fineneedle aspiration biopsy samples from swollen lymph nodes and subcutaneous masses showed an increased number of lymphoid cells, suggesting cutaneous lymphomatosis. However, a critical examination of the smears from subcutaneous nodules showed a large number of Koch's blue bodies in macrophages and lymphoblasts, and several piroplasms were also noticed within the red blood cells in lymph node smears. A peripheral blood smear revealed mild to moderate parasitaemia. Extracted DNA from the parasitologically positive blood sample was subjected to nested polymerase chain reaction (nPCR) using T. annulata speciesspecific primers encoding the 30-kiloDalton major sporozoite surface antigen. The desired 572-base pair amplified product of the nPCR was comparable to the positive control. This seems to be a rare case of T. annulata in an adult cross-bred cow, showing cutaneous nodular involvement.

Abstract
In the Indian sub-continent, equine piroplasmosis (EP) is an imperative tick-borne disease of equids predominately caused by obligatory intra-erythrocytic protozoa Theileria equi. Present exploration is the first epidemiological survey report based on Indirect Immunofluorescence Antibody test (IFAT). A total of 120 equines (98 horses and 22 donkeys/mules) from five districts of two main agro-climatic zones of Punjab were screened. The overall prevalence was 58.33%, with western plane zone at higher infection risk for T. equi (74.50%, OR = 7.45, 95% CI = 62.24-85.76); followed by western zone (46.38%, OR = 4.63, 95% CI = 34-57.7). District wise highest and lowest prevalence was recorded in district Fazilka (80.76%) and Bathinda (35.29%) respectively. IFAT revealed elevated risk of infection of T. equi in the farms with inappropriate management structure. The risk factor connected with the type of host species had an odds ratio of 1.67 for donkeys/mules versus horses for T. equi infection. Followed by presence/absence of tick on animal. This study reveals the endemicity of EP in Punjab with prominence of various odds of infection, associated with latent infection of T. equi detectable by serological techniques as it was noticed that western plane zone and western zone are more prone to EP infection.

Abstract
Ancylostoma caninum, a blood feeding nematode parasite (Family: Ancylostomatidae, Superfamily: Ancylostomatoidea) can cause anaemia, dark reddish-brown to black haemorrhagic diarrhoea, dehydration, wasting and deaths due to heavy blood loss. Adult hook worm parasites recovered from the intestine of a stray dog at the time of necropsy were identified as A. caninum based on morphological characters and morphometric observations involving scanning electron microscopy (SEM). Different developmental stages of hookworm eggs viz. 8 cell stage, morula, gastrula and vermiform were observed during the culture process of faecal sample. High quality SEM photographs showed teeth of dimensions 52.5, 42.3 and 23.5 μm on one side and 55.4, 43.8 and 21.0 μm on the other side along with the presence of characteristic transverse cuticular striations on body surface of A. caninum parasites.

Abstract
Summary
The eggs recovered during faecal screening of Asiatic lions (kept at MC Zoological Park, Punjab, India) were delineated as Toxascaris leonina eggs based on morphometric and molecular studies (polymerase chain reaction targeting internal transcribed spacer sequences). Therapeutic management with fenbendazole @10 mg/kg body weight, once daily orally for three consecutive days proved ineffective with maximum faecal egg count reduction (FECR) on day 3 post treatments (69.35 %). But, therapeutic intervention with extended period dose schedule (5 consecutive days) with fenbendazole (@10 mg/kg body weight) proved effective and showed a maximum FECR of 95.34 % at day 7 post treatments. But, when ivermectin (@100μg/kg body weight) was given orally on three alternate days, proved effective as FECR of 95.74 % was recorded at day 7 post treatments. Thus, present study highlights the molecular confi rmation of T. leonina and its management using fenbendazole and ivermectin in Asiatic lions.

Abstract
Equine piroplasmosis caused by Theileria equi, an apicomplexan intracellular haemoprotozoan parasite effects equids throughout the world. Current investigation is the first detailed epidemiological survey report based on conventional (blood smear) and primary polymerase chain reaction (PCR) for the detection of T. equi on 464 equids (426 horses and 38 donkeys/mules) in Punjab province of India. PCR targeting 18S rRNA gene of T. equi produced high fidelity 709bp amplification products with 100% concordance with blood films. The prevalence of infection was proportional (P≤0.01) to temperature and aridness of the regions, which turned out to be the most important physical factor pertaining to T. equi infection. Spatial distribution analysis revealed an increasing trend of disease prevalence from north-eastern to south-western region of Punjab by both the techniques. Haemato-biochemical analysis revealed significant decrease in total erythrocyte count and haemoglobin; and increase in mean corpuscular haemoglobin, serum globulin, glucose, creatinine, aspartate aminotransferase and bilirubin levels (P≤0.05). This study divulges the endemicity of equine theileriosis in Punjab with the prominence of various odds of infection, emphasising the pathophysiological manifestation associated with latent infection of T. equi detectable by PCR.

Abstract
AIM The aim of this study was to explore the prevalence of gastrointestinal parasitism in small ruminants in relation to various risk factors in the western zone of Punjab. MATERIALS AND METHODS During the study, 603 fecal samples (391 of sheep and 212 of goats) were examined qualitatively by floatation and sedimentation techniques, and quantitatively by McMaster technique. RESULTS Out of the 603 fecal (391 sheep and 212 goats) samples examined, 501 were found positive for endoparasitic infection with an overall prevalence of 83.08%, consisting of 85.16% and 79.24% in sheep and goats, respectively. Egg per gram in sheep was apparently more 1441.88±77.72 than goats 1168.57±78.31. The associated risk factors with the prevalence of gastrointestinal tract (GIT) parasites showed that females (85.97%) were significantly more susceptible than males (69.23%). Age wise the adults (>6 months) were significantly more prone to parasitic infection as compared to young ones (<6 months). Seasonal variation was recorded throughout the year and was significantly highest during monsoon (90.10%), followed by winter (83.84%) and summer (78.35%). CONCLUSION The study revealed an overall prevalence of 83.08% of GIT parasitic infections in small ruminants constituting 85.16% in sheep and 79.24% in goats in the western zone of Punjab. The most relevant risk factors for the prevalence of gastrointestinal parasitism in ruminants were sex, age, and season.

Abstract
Anthelmintic resistance against commonly used anthelmintic fenbendazole was evaluated by employing faecal egg count reduction test (FECRT) in naturally occurring gastrointestinal (GI) nematodes in the semi organized sheep and goat farms of Ludhiana and Amritsar districts. A total of 80 animals (20 each for sheep and goat in both districts) were randomly selected and their faecal samples were examined by qualitative and quantitative parasitological techniques. Results indicate presence of high level of resistance against fenbendazole in both sheep and goat population of Ludhiana and Amritsar districts. More resistance was observed in the GI nematodes from animals reared in Amritsar district as compared to Ludhiana district. The level of anthelmintic resistance observed was apparently more in sheep than goats.

Abstract
Cryptosporidiosis is an emerging waterborne protozoan disease and one of the major causes of neonatal diarrhea in humans and animals. But the disease remains under diagnosed due to lack of availability of special stains in majority of laboratories at primary health centers. Therefore, it requires a rapid screening test for routine diagnosis in conventional laboratory set up. In this pursuit, the present study was planned. During this study, fecal samples from 100 representative animals randomly selected from 17 out breaks of bovine calf diarrhea, were stained with modified Ziehl Neelsen staining (mZN) and Leishman's stain to demonstrate cryptosporidial oocysts and for routine fecal examination, respectively. By mZN staining, 25 cases confirmed the presence of cryptosporidial oocysts. However, examination of Leishman's stained fecal smears revealed round hollow unstained bodies resembling cryptosporidia in 20 cases. Therefore, a comparative morphometric analysis was made between the two techniques to determine their relative efficacy in demonstrating cryptosporidia in the feces of affected animals. The analyses showed that the Leishman's stain can be effective in making a presumptive diagnosis of cryptosporidiosis with a little experience. Confirmation of cryptosporidiosis was done by histopathological examination of intestinal sections of calves died during these out breaks. The findings appear to have great clinical value for routine laboratory screening of fecal samples for cryptosporidiosis as conventional Romanowsky stains are readily available and used for multipurpose examination in most of the laboratories at grass root level. Perusal of literature proved this to be the first attempt at easy diagnostics for cryptosporidiosis.

Abstract
Aim: The study was conducted to know the prevalence of gastrointestinal parasites of captive wild animals at Bir Moti Bagh Mini Zoo (Deer Park), Patiala, Punjab. Materials and Methods: A total of 31 fecal samples from eight species of captive animals including Civet cat (Viverra zibetha), Porcupine (Hystrix indica), Nilgai (Boselaphus tragocamelus), Spotted deer (Axis axis), Black buck (Antelope cervicapra), Sambar deer (Cervus unicolor), Hog deer (Axis porcinus), and Barking deer (Muntiacus muntjak) were screened using classical parasitological techniques including sedimentation and floatation technique. Results: Out of 31 fecal samples examined, 20 were positive for parasitic ova/oocysts of different species indicating an overall prevalence of 68.0%. The six different types of parasites observed in the study included strongyle (67%), Strongyloides spp. (14%), coccidia (38%), Trichuris spp. (19%), ascarid (10%), and Capillaria spp. (10%). Strongyles were the most common parasites observed (67%) followed by coccidia (38%). Mixed helminth and protozoan infection were observed in 48% of animals. No cestode or trematodes were detected during the study. Conclusion: The high prevalence of gastrointestinal parasites without overt clinical signs of disease or mortality as observed in this study is suggestive of subclinical infection. The findings will help in formulating the appropriate deworming protocol for parasitic control in these captive animals.

Abstract
Equine piroplasmosis is a febrile, tick-borne disease of equids predominately caused by obligatory intra-erythrocytic protozoa Theileria equi in the Indian sub-continent. A cross-sectional study was carried out on 464 equids (426 horses and 38 donkeys/mules) in Punjab, India to assess the level of exposure to equine piroplasmosis by 18S rRNA gene nested polymerase chain reaction (nPCR) and equine merozoite antigen-2 (EMA2) indirect-ELISA (enzyme linked immunosorbent assay), to investigate risk factors and haemato-biochemical alterations associated with the infection. The endemicity of the disease was confirmed by positive PCR amplification in 21.77% and positive antibody titers in 49.78% equid samples. There was a fair agreement between these two diagnostic techniques (Kappa coefficient=0.326). The spatial distribution analysis revealed an increasing trend of T. equi prevalence from north-eastern to south-western region of Punjab by both the techniques correspondingly, which proffered a direct relation with temperature and inverse with humidity variables. The relatively prominent risk factor associated with sero-positivity was the presence of other domestic animals in the herd, while the propensity of finding a positive PCR amplification was higher in donkeys/mules, animal kept at unorganised farm or those used for commercial purposes as compared to their counterparts. There was a significant increase in globulins, gamma glutamyl-transferase, total bilirubin, direct bilirubin, indirect bilirubin, glucose levels and decrease in total erythrocyte count, haemoglobin, packed cell volume by animals, which were revealed positive by nPCR (may or may not positive by indirect-ELISA) and increase in creatinine, total bilirubin, direct bilirubin, glucose and decrease in total erythrocytes count by animals, which were revealed positive by indirect-ELISA (alone). To our knowledge, this study, for the first time, brings out a comprehensive report on the status on spatial distribution of T. equi in Punjab (India) state, thoroughly investigated by molecular and serological techniques, evaluating various environmental and demographic risk factors along with the haemato-biochemical alterations in the exposed animals.

Abstract
An overall prevalence of 38.90 % was recorded for bovine cryptosporidiosis on coprological examination of 144 faecal samples collected from neonatal cattle calves from organised dairy farms in and around Ludhiana, Punjab by modified Ziehl-Neelsen staining. Further, a gradual decline in the percent prevalence was seen with increase in the age of the host from <1 month (64.1 %) to 4-5 months (12.5 %). The highest prevalence was recorded during the monsoon season (47.06 %) followed by summer (37.73 %) and winter (30.0 %) season and the seasonal variation was statistically significant (p ≤ 0.05). Female calves showed higher prevalence (44.32 %) than their male counterparts (27.66 %). Further, prevalence of cryptosporidiosis was significantly higher (p ≤ 0.05) in the diarrhoeic calves (52.70 %) as compared to the non-diarrhoeic (24.28 %) thus indicating a relatively higher risk (1.75 times) of the disease in diarrhoeic than normal calves.

Abstract
Out of 44 cases of dermatitis in dogs, 11 cases of parasitic origin were analyzed by cytopathology. Histopathologic examination of punch biopsies was also done for correlation with cytologic findings. Sarcoptic dermatitis was recorded in six cases, wherein, besides sarcoptic mites, neutrophils, macrophages, and plasma cells and keratinizing epithelial cells were also seen. Hematology revealed a relative neutrophilia and mild eosinophilia. Four cases of severe and generalized demodicosis complicated with bacteria and/or Malassezia sp. infection were also recorded. Histopathologically numerous Demodex sp. mites in varying stage of maturation were found damaging the hair follicles along with associated pathological changes and foreign body granulomas in one case. In addition, flea allergy dermatitis was also observed in one dog. In nutshell, cytology was found to be unequivocally effective in diagnosing parasitic dermatitis.

Abstract
A rare case of canine hepatozoonosis in a mongrel dog with para-clinico-pathological observations has been reported. The study included detailed haemato-biochemical changes at two stages, i.e. before treatment and after treatment with adopted therapy. Before therapy, blood picture revealed normocytic hypochromic anaemia and neutrophilic leucocytosis with variable counts of platelets. Thirty-seven percent of neutrophils were found infected with gametocytes of Hepatozoon canis. Following treatment, further decrease in haemoglobin value with a relative increase in lymphocyte count was seen. Biochemically, increase in alkaline phosphatase, blood urea nitrogen and creatinine levels along with hyperproteinemia was seen. The 14 days chemotherapy did not bring a respite for the dog and the level of parasitaemia was 33% after the treatment. The alkaline phosphatase and creatinine level further rose up following therapy with sulphadiazine and clindamycin. Continual study is required to explain the best possible therapeutic combination to deal H. canis.

Abstract
Dot-ELISA (enzyme-linked immunosorbent assay) Immunocomb(®) assay was conducted to detect the presence of antibodies against Ehrlichia canis in blood samples of 60 privately owned dogs suspected to be infected with E. canis from the Small Animal Clinics, College of Veterinary Science, Guru Angad Dev Veterinary and Animal Sciences University, Ludhiana, Punjab (India). Antibodies reactive to E. canis were detected in plasma in 48 samples out of 60 samples by Immunocomb(®) Dot-ELISA. Out of these 39.58% samples were low positive (Titre 1:20-1:40), 31.25% were medium positive (Titre 1:80-1:640) and 29.16% were high positive (Titre >1,280), for the infection. When examined by microscopy, only two samples revealed typical E. canis morulae. Haemato-cellular examination revealed thrombocytopenia along with anaemia and leucopenia. Results suggest that E. canis infection circulates in dogs in India in low non-detectable numbers by microscopy and is transmitted by the brown dog tick Rhipicephalus sanguineus.

Abstract
For comparative evaluation, a real time PCR assay was standardized by using TaqMan primer and probe targeting the internal transcribed spacer 1 (ITS-1) region of rRNA for Trypanosoma evansi and sensitivity was evaluated by using DNA, extracted from diethyleamino ethane cellulose purified trypanosomes and trypanosomes infected whole blood of mice. The minimum detection limit for purified trypanosomal DNA was 0.01 ng (≈ 0.33 genomic DNA of T. evansi) whereas for whole blood the minimum detection limit was 0.1 ng (≈ 6.12 genomic DNA). T. evansi infected mice blood samples were collected at different interval post infection and were analysed by conventional parasitological methods (CPT) viz. wet blood smear, thin blood smear, thick blood smear, quantitative buffy coat and real time PCR and found that TaqMan assay was two fold sensitive than CPT in case of in vivo infectivity in mice and gave positive signal at 36 h post infection where as QBC and blood smear examination was able to detect at 60 h and 72 h post infection respectively. A total 109 (80 cattle and 29 buffaloes) blood samples were collected from in and around Ludhiana district and analysed by CPT and real time PCR. The overall prevalence of T. evansi by CPT in cattle and buffaloes was 2.75 per cent. The prevalence rate was 2.5 per cent in cattle and 3.45 per cent in buffaloes. By real time PCR overall prevalence was 12.84 per cent in cattle and buffaloes, with a prevalence rate of 12.50 per cent in cattle and 13.79 per cent in buffaloes.

Abstract
The present report describes outbreak of cryptosporidiosis in neonatal cross bred cattle calves ageing 1–2 months in an organized dairy farm. The protozoan infection was confirmed by identifying bright red oocysts of Cryptosporidium spp. in the faecal samples after staining with modified acid Fast Zeihl–Neelsen stain. Metronidazole and furazolidone combination was able to induce clinically and parasitological recovery. This is believed to be the first report on the successful use of this drug combination against cryptosporidiosis.

Pulmonary paragonimiasis is an important zoonotic disease reported from many parts of the world. It is an endemic problem in human population in north-eastern states of India. There seems no report of pulmonary paragonimiasis in canine population from India. The present case describes first report of pulmonary paragonimiasis in a female dog suggesting possibility of this fluke becoming established in canine population in the country. The dog revealed mild coughing with serous nasal discharge. Faecal sample revealed eggs of Paragonimus spp. Treatment with fenbendazole resulted in marked improvement as revealed by clinical signs and chest radiography.

Abstract
Indirect plate enzyme-linked immunosorbent assay was standardized and evaluated for its effectiveness in immunodiagnosis of paramphistomosis in experimental and clinical cases in sheep, goat, cattle and buffaloes by using somatic whole adult antigen of Paramphistomum epiclitum and Gastrothylax crumenifer. Plate enzymelinked immunosorbent assay (ELISA) was standardized using 2 μg/ml of antigen concentration with 1:200 and 1:1,000 of sera and conjugate dilution. Indirect Plate ELISA was able to demonstrate the antibody titre at different weeks postinfection in experimental sheep. Immune response at weekly interval varied in all the four experimental sheep. A paired t-test between two types of somatic antigens (P. epiclitum and G. crumenifer) showed that experimental sheep sera showed more affinity for homologous antigen as compared to heterologous antigen. A comparison of plate ELISA on suspected field sera and fecal samples examination by sedimentation method revealed that 77 samples were found to be positive by ELISA but only seven by fecal examination. Sensitivity of plate ELISA was found to be 85.71%, whereas specificity was 23.65% indicating that this test is quite sensitive for clinical cases; an early diagnosis, however, lacks specificity. In comparison to ELISA test the sensitivity and specificity of fecal examination were 7.79 and 88%, respectively.
