Maternal transfer of immunity does not occur in utero but post-parturition, however this does not compensate for potential deficits in the cellular compartment. Here we present a cellular and transcriptomic study to investigate if there is an age-related difference in the monocyte response in cattle during intra-cellular protozoan infection. We utilized Neospora caninum, an obligate intracellular protozoan parasite that causes abortion and negative economic impacts in cattle worldwide, to study these responses. We found neonatal animals had a significant greater percentage of CD14 + monocytes with higher CD80 cell surface expression. Adult monocytes harbored more parasites compared to neonatal monocytes; additionally greater secretion of IL-1β was observed in neonates. Microarray analysis revealed neonates have 535 genes significantly upregulated compared to adult with 23 upregulated genes. Biological pathways involved in immune response were evaluated and both age groups showed changes in the upregulation of tyrosine phosphorylation of STAT protein and JAK-STAT cascade pathways. However, the extent to which these pathways were upregulated in neonates was much greater. Our findings suggest that neonates are more resistant to cellular invasion with protozoan parasites and that the magnitude of the responses is related to significant changes in the JAK-STAT network.

The prevalence of gastrointestinal (GI) parasitic infections in adult animals was 37.97%. Strongyle (18.99%) the most prevalent GI parasite followed by Eimeria sp. (13.42%), Moniezia expansa (5.57%), amphistomes (3.80%), Strongyloides papillosus (1.01%), Trichuris sp. (0.76%) and Fasciola sp. (0.51%). In calves the prevalence of Toxocara vitulorum, strongyle, S. papillosus, Eimeria sp. and M. expansa was 6.01, 21.89, 20.17, 53.22 and 3.43%, respectively. In calves, the overall prevalence of GI parasitic infections was found to be more as compared to adults and T. vitulorum was recorded only from calves of less than six months of age. The baseline data on the prevalence of various GI parasites of bovids generated in the current study would be of immense help in formulating control strategies against these parasites in the western plains of the state.

A total of 627 faecal samples were examined and the overall prevalence of GI parasitic infection was 61.40%. The prevalence of Toxocara vitulorum, strongyle, Strongyloides spp., Eimeria spp. and Moniezia spp. Was 2.71, 23.29, 14.51, 44.18 and 3.67 per cent, respectively. The overall prevalence of parasitic infections was almost comparable and no significant difference (P≥0.05) was recorded among the two sexes of cow calves. However, strongyle and Eimeria spp. infection showed a positive correlation with age. The prevalence of various parasitic infections was found to be highest in rainy season with significant differences (P<0.01) as compared to summer and winter seasons. Among the various agro-climatic zones, highest prevalence of T. vitulorum, S...

The extracts were prepared by cold extraction method by standard protocols. The concentrations of extracts used were 1:10, 1:15, 1:20, 1:25, 1:30 and 1:35 and the results were recorded at different period of exposure time (6 h, 12 h, 24 h, 48 h, 72 h and 96 h). The different concentrations of methanolic extract of neem showed variable effect on adult stages of L. auricularia and I. exustus. A total of 15 snails were used in triplicate in each treated and control group, respectively. It showed positive correlation between exposure time and mortality and negative correlation between dilution and mortality. Among the different extracts, the whole plant extract was most effective followed by seed, leaf and bark against snails L. auricularia and I. exustus. I. exustus was found to be more suscep...

Examination of Giemsa stained peripheral blood smears exhibited 10.21% (47/460) haemoprotozoan comprizing of Babesia gibsoni (8.26%), Hepatozoon canis (1.08%), B. canis (0.65%) and Trypanosoma evansi (0.21%). B. gibsoni infection was significantly higher (p<0.05) in male dogs. Coprological examination revealed that the prevalence of gastro-intestinal parasitic infection was 24.71% (43/174). Among these Isospora spp. and Ancylostoma spp. were 2.29 and 22.41%, respectively. The present work emphasized that B. gibsoni and hookworms were most prevalent blood- and gastro-intestinal parasites in canines in and around Ludhiana, Punjab (India).

Examination of Giemsa stained peripheral blood smears revealed an overall prevalence of haemoprotozoan infections as 8.60% that comprised Trypanosoma evansi, Babesia gibsoni, B. canis, Ehrlichia canis and Hepatozoon canis as 0.40, 4.51, 1.43, 1.43 and 0.82%, respectively. Faecal floatation test revealed that the overall prevalence of GI parasitic infections was 26.09%. The prevalence of Isospora sp., Dipylidium caninum, Ancylostoma sp., Taenia sp. and Trichuris vulpis was 3.86, 0.97, 19.32, 1.45 and 0.48%, respectively. The hookworms were the most prevalent GI parasites of dogs. Sex wise and age wise no significant differences were recorded between various groups in the prevalence of GI parasitic infections. Out of a total of 134 skin scrapings examined the prevalence of mange mites was recorded to be 28.36%. The prevalence of...

Synthetic pyrethroids particularly deltamethrin and cypermethrin have been used extensively to control Rhipicephalus (Boophilus) microplus in most parts of Punjab, India for the past decade leading to tick populations resistant against both the acaricides. Ticks (R. microplus) were collected from dairy farms at Haibbowal Dairy Complex, Ludhiana, Punjab and were subjected to adult immersion test with a discriminating dose (AITDD) against deltamethrin and cypermethrin. Results revealed a very high degree of resistance against deltamethrin (96.67%) and cypermethrin (93.33%) indicating need for adoption of alternative tick control strategy.

R. microplus was the predominant tick in cattle population (85.28%), whereas in buffalo population R. microplus and H. a. anatolicum were almost evenly distributed. Among the different agro-climatic zones a significantly higher prevalence of H. a. anatolicum was recorded in both cattle and buffalo population of Western Plain and Western regions with comparison to other regions i.e. Central Plain and Undulating Plains of the state. H. a. anatolicum was recorded more in summer (23.1%) and monsoon (21.0%) seasons compared to winter (6.10%). In cattle, the tick infestation was similar in both the sexes whereas in buffalo, R. microplus was predominating in males and H. a. anatolicum was pr...

An amplicon of 237 bp size specific for T.evansi was detected in 4.8% of blood samples against the routine blood smear examination, which did not reveal the parasite in any of the samples. These results demonstrated that parasitic infection by T. evansi was present in cryptic form and PCR could detect such cases.

Blood smears examination of 104 healthy carrier cow calves and adults revealed 16 animals positive for T. annulata whereas, amplification product of 721 bp size specific for T. annulata was detected from 40 samples. The results demonstrated that the PCR test was a valuable technique fordetection of carrier or low grade infection of T. annulata under field conditions.
