Aim: The aim was to determine hemato-biochemical alterations and to determine the better treatment of theileriosis in naturally infected calves.

Materials and Methods: A total of 74 Holstein crossbred calves below 6 months of age, of either sex were included for present investigation in Bikaner. Based on the clinical examinations and laboratory results, 20 calves included for hemato-biochemical studies (before and after treatment) and divided into two groups (having 10 calves each).

Results: The clinical examination of these calves revealed weakness, ticks infestations, high fever above 104°F, pronounced swelling of prescapular, prefemoral, parotid lymph nodes, loss of elasticity of skin, anemia, lacrimal discharges, pulpy cornea, tachycardia, and dyspnea. There was highly significant decrease (p<0.01) in hemoglobin, total erythrocyte count, packed cell volume and total leukocyte count, serum glucose, total protein, globulin and albumin level and highly significant increase in aspartate aminotransferase and alanine aminotransferase level as compared to healthy control animals in Group I and II. The animals of Group II treated with buparvaquone along with single blood transfusion shows better recovery then animals of Group I treated with bupavaqone and hematinic.

Conclusions: Significant changes were found in hemato-biochemical parameters in theileria affected calves before treatment as compare to healthy control calves. Significant improvement was observed in hemato-biochemical parameters in buparvaquone and single blood transfusion treated calves as compare to another group, so it is concluded that buparvaquone and single blood transfusion is better combination for treatment of theileriosis.

Aim: This study aims to study the estrus induction, ovulation, and conception rate of delayed puberty in buffaloes heifers by feeding a herbal plants Aegle marmelos (bael/bili/bhel leaf) and Murraya koenigii (Curry leaf).

Materials and Methods: Totally, 24 buffalo heifers with delayed puberty were selected for the present study and divided randomly in four equal groups (n=6). Before experiment, all animals were dewormed with albendazole at 10 mg/kg body weight to prevent them from the stress of parasitism. In the present experiment, four group taken and Group I (n=6) treated with A. marmelos, Group II (n=6) treated with M. koenigii, Group III (n=6) treated with mixture of A. marmelos and M. koenigii and fed for 9 days. Group IV (n=6) considered as control and fed with concentrate only. The blood samples were collected from all the animals on day 0 (before treatment), 4, 9 (during treatment), on the day of estrus and day 8 after the onset of estrus. The 10 ml blood was collected from the jugular vein of all the experimental animals for estimation of serum calcium, inorganic phosphorus, and progesterone (P₄). The estrus response, ovulation, conception rate along with serum calcium, inorganic phosphorus, and progesterone level were determined by the standard protocol.

Results: From Group III 4 heifers, from Group II 3 heifers, and from Group I and IV (Control) 2 heifers each, exhibited the estrus. The estrus response was recorded as 33.33%, 50.00%, 75.00%, and 33.33% in Group I, Group II, Group III, and Group IV, respectively. In treatment Group III, serum calcium found significantly more (p<0.05) on day 8 post-estrus as compared to other groups at a similar interval. Inorganic phosphorus and progesterone show no significant difference between groups. The ovulation and conception rates are comparatively better in Group III (75%) buffalo heifers than other groups.

Conclusion: Herbal supplementation of A. marmelos and M. koenigii in combination, as well as M. koenigii alone, were found effective in fertility improvement in delayed pubertal buffalo heifers by increasing ovulation and conception rate.

Aim: The aim of the present study was to diagnose severe outbreaks of bovine babesiosis in Punjab state, in the year 2015 and to suggest control and preventive measures to animal owners.

Materials and Methods: Mortality of animals was recorded in two cattle herd comprising a total of 465 cattle in Sangrur (n=125) and Faridkot (n=340) districts. There was a history of purchase of animals at one farm. 23 blood samples were collected from diseased (n=15) and healthy animals (n=8) for hematological analysis, parasitological, and polymerase chain reaction (PCR)-based diagnosis. Ticks were also collected from animals for identification.

Results: Out of 465 cattle at risk, 28 were critically ill and 14 died of disease with morbidity, mortality, and case fatality rate of 6.02%, 3.01%, and 50.00%, respectively. Clinical signs and necropsy findings were suggestive of babesiosis. Ticks collected from both the outbreaks were identified as Rhipicephalus (Boophilus) microplus. Thin blood smears from infected animals (especially with clinical sign of hemoglobinuria) were found positive for Babesia bigemina organisms; however, molecular diagnosis (PCR) further confirmed the disease. Animals were successfully treated with diminazene aceturate, hematinics, and antipyretics.

Conclusions: Two fatal outbreaks of babesiosis in cattle were diagnosed with application of conventional parasitological, hematological, and molecular diagnostic techniques. PCR was found to be far more sensitive in detecting the disease, especially in latent infections. Animal owners were advised to follow quarantine measures before mixing new animals in the herd and strategic acaricidal treatments for effective tick control.

Aim: This study was conducted for the isolation and molecular characterization of bovine herpesvirus 1 (BoHV-1) isolated from the nasal and vaginal swabs collected from naturally infected cattle showing clinical symptoms of the respiratory disease.

Materials and Methods: Isolation of BoHV-1 virus performed on clinical samples collected from 65 cattle from five states of India. The BoHV-1 isolates were further confirmed by polymerase chain reaction (PCR) using primers specific for glycoprotein B (gB) genomic region. PCR amplification was performed using previously published gB gene-specific primer pairs. gB PCR amplicons obtained from all isolates were sequenced, and phylogenetic analysis was performed using software.

Results: A total of 12 samples were found positive in cell culture isolation. 11 isolates showed the visible cytopathic effect on Madin-Darby bovine kidney after 72 h. Partial sequence analysis of gB gene of all isolates revealed 99.0-100% homology between them. All isolates showed 99.2-99.8% homology with Cooper stain.

Conclusion: BoHV-1.1 is the predominant circulating subtype of BoHV in India, and all isolates have homology with Cooper stain.

Aim: Cystic echinococcosis (CE) represents a serious parasitic disease at both animal and public health levels. The majority of reports negated the CE infection in buffaloes from Egypt; however, one study illustrated their infection with G6 genotype (camel strain). The present work contributed to update the epidemiological and molecular knowledge about CE infecting this economically important animal for better understanding of its role in maintaining the Echinococcus life cycle.

Materials and Methods: A total of 120 slaughtered water buffaloes at Mansoura abattoir, Dakahlia province, Egypt, were inspected for the existence of hydatid cysts. Cysts location and fertility were examined. Five out of 27 revealed cysts were tested molecularly using both cytochrome C oxidase subunit 1 and nicotinamide adenine dinucleotide hydrogen subunit 1 (nadh1) genes.

Results: Low prevalence (4.2%) as well as considerably low fertility rate (14.8%) of buffaloes CE was noted. G1 genotype (common sheep strain) was revealed from the five examined cysts. At the level of nadh1 partial sequences, a globally singleton G1 haplotype was reported.

Conclusion: This the first report about the G1 infection in buffaloes from Egypt. This study proposed the minimized role of this animal in echinococcosis transmission. These findings could provide preliminary data for the local control of this disease.

Keywords: buffalo, Echinococcus, Egypt, genotype, prevalence.

Aim: This research was conducted to identify the expression of choline acetyltransferase (ChAT) in human cerebral microvascular endothelial cells (HCMECs) and to clarify the capability of Ocimum sanctum Linn. ethanolic extract to stimulate the presence of ChAT in the aging HCMECs.

Materials and Methods: In this study, we perform an in vitro analysis some in the presence of an ethanolic extract of O. sanctum Linn. as a stimulator for the ChAT expression. HCMECs are divided become two groups, the first is in low passage cells as a model of young aged and the second is in a high passage as a model of aging. Furthermore to analysis the expression of ChAT without and with extract treatments, immunocytochemistry and flow cytometry analysis were performed. In addition, ChAT sandwich enzyme-linked immunosorbent assay is developed to detect the increasing activity of the ChAT under normal, and aging HCMECs on the condition treated and untreated cells.

Results: In our in vitro models using HCMECs, we found that ChAT is expressed throughout intracytoplasmic areas. On the status of aging, the ethanolic extract from O. sanctum Linn. is capable to stimulate and restore the expression of ChAT. The increasing of ChAT expression is in line with the increasing activity of this enzyme on the aging treated HCMECs.

Conclusions: Our observation indicates that HCMECs is one of the noncholinergic cells which is produced ChAT. The administrated of O. sanctum Linn. ethanolic extract may stimulate and restore the expression of ChAT on the deteriorating cells of HCMECs, thus its may give nerve protection and help the production of acetylcholine.

Aim: To know the prevalence of gastrointestinal nematode larvae (L₃) in the grazing land of cattle in Guwahati, Kamrup district, Assam.

Materials and Methods: Pastures were collected and examined for the presence of nematode larvae (L₃) from six localities of Guwahati at monthly interval from August 2012 to July 2013. The counted larvae were then expressed as per kg dry matter of herbage (L₃/kg DM).

Results: Examination of pastures revealed presence of nematode larvae (L₃) in pastures throughout the year which varied from 4.5 L₃/kg DM in January to a maximum of 106.33 L₃/kg DM in August. The L₃ of Haemonchus contortus, Trichostrongylus spp., Oesophagostomum spp., Cooperia spp., and Mecistocirrus spp. were recovered from pastures. The average pasture larval burden (PLB) was 34.75±3.48 L₃/kg DM. Season-wise PLB revealed the presence of 23.89±3.01, 67.54±5.41, 26.67±1.92, and 7.28±0.89 L₃/kg DM during pre-monsoon, monsoon, post-monsoon, and winter seasons, respectively. Monsoon season has significant (p<0.05) effect on PLB. However, analysis of variance of different locations with respect to season revealed that there was no significant difference but season-wise it was highly significant (p<0.01). Pearson correlation of environmental variables (temperature, relative humidity, and rainfall) with PLB revealed correlation was statistically significant with rainfall (p<0.05).

Conclusion: This study reveals the presence of five nematode larvae (L₃) in the pastures of Guwahati, Assam throughout the year, statistically significant during monsoon season.
