ABSTRACT

Ultrasonography, a non-invasive and useful technique, is used for the examination of Atlanto-occipital space structural visualization. The collection of cerebrospinal fluid is more accurate and easier under ultrasound-guided procedure. In this study, longitudinal and transverse views of the Atlanto-occipital space were scanned and their different structural dimensions were measured in sixty healthy Beetal goats. In longitudinal plane, gap between skin and arachnoidea ranged from 8.71 to 10.21 mm (mean ± SD, 9.76 ± 0.44 mm). Depth of the subarachnoid gap dorsal and ventral to the spinal cord ranged from 2.14 to 3.23 mm (mean ± SD, 2.81 ± 0.33mm) and from 6.09 to 7.68 (mean ± SD, 7.02 ± 0.45 mm) respectively. Spinal cord diameter varied from 3.76 to 5.26 mm (mean ± SD, 4.57 ± 0.44 mm) and entire dural sac diameter varied from 12.59 to 15.69 mm (mean ± SD, 14.37 ± 0.74 mm). The spinal cord can be seen only in longitudinal plane over a distance of 1.81 to 2.93 mm (mean ± SD, 2.46 ± 0.35 mm). While in the transverse plane, gap between the skin and arachnoidea ranged from 11.01 to 13.11 mm (mean ± SD, 12.39 ± 0.54 mm). Depth of the subarachnoid space dorsal and ventral to spinal cord varied from 5.05 to 6.13 mm (mean ± SD, 5.59 ± 0.34 mm) and 4.12 to 5.25 (mean ± SD, 4.65 ± 0.29 mm) respectively. Spinal cord diameter ranged from 4.45 to 5.90 mm (mean ± SD, 5.24 ± 0.44 mm) and entire dural sac diameter varied from 14.68 to 16.96 mm (mean ± SD, 15.58 ± 0.57 mm). These standard measurements will be the reference values in healthy Beetal goats. Cerebrospinal fluid was colourless with the quantity of 2-4 ml (mean ± SD, 3 ± 0.89 ml). It was neither turbid nor coagulate. The white blood cell count was 10/µl and red blood cells were not present. Furthermore, total protein and glucose were also measured, which ranged from 23.5 to 28 mg/dl (mean ± SD, 25.78 ± 2.32 mg/dl) and 38-50 mg/dl (mean ± SD, 43.33 ± 4.60 mg/dl) respectively. Ziehl-Neelsen Staining and gram staining were negative.

ABSTRACT

Nanotechnology is the discipline and technology of small and specific things that are < 100 nm in size. Because of their extremely miniscule size, any changes in their chemical and physical structure may show higher reactivity and solubility than larger particles. Nanotechnology plays a vital role in every field of life. It is considered one of the most bleeding edge field of scientific research. It has already several applications in a myriad of disciplines while its application in the field of animal production and veterinary medicine is still experimental in nature. But, in recent years, the role of nanotechnology in the aforementioned fields of scientific inquiry has shown great progress. These days, nanotechnology has been employed to revolutionize drug delivery systems and diagnose atypical diseases. Applications of nanoparticle technology in the field of animal reproduction and development of efficacious vaccines have been at the forefront of scientific endeavors. Additionally, their impacts on meat and milk quality are also being judiciously inquired in recent decades. Veterinary nanotechnology has great potential to improve diagnosis and treatment, and provide new tools to this field. This review focuses on some noteworthy applications of nanoparticles in the field of animal production and their future perspectives.

ABSTRACT

Leptospirosis is a worldwide emerging infectious disease of zoonotic importance and large epidemics and epizootics have been reported all over the globe. A cross survey study was conducted to estimate seroprevalence of human leptospirosis in climatically distinct regions of Pakistan and to identify the risk factors associated with the disease. Blood samples from 360 humans were collected through convenient sampling, 120 from each of three study areas. Serological testing was performed using ELISA kit as per manufacturer's recommendations. The results showed an overall prevalence of 40.83% (95% CI; 35.71-46.11). Statistical analysis showed significant (P < .05) differences in leptospiral seroprevalence in three different geographic locations, with highest in humid sub-tropical climatic region (50.83%; 95% CI; 41.55-60.07), followed by semi-arid region (44.16%; 95% CI; 35.11-53.52) and lowest in hot and dry region (27.50%; 95% CI; 19.75-36.40). After multivariate analysis age, gender, exposure to flooding water, source of water usage, disinfection schedule of surroundings and history of cut and wound were found significantly associated with the seropositivity of Leptospira. The present study, first to uncover seroprevalence of human Leptospira in different climatic regions of Pakistan, alarms about effect of climate on prevalence of Leptospira in the region.

ABSTRACT

Surveillance of Rotavirus A (RVA) infections in North America swine populations are limited and not performed over a significant time period to properly assess the diversity of RVA strains in swine. The VP7 (G) and VP4 (P) genes of 32 Canadian RVA strains, circulating between 2009 and 2015 were sequenced, identifying the G3P[13], G5P[7], G9P[7], G9[13], and G9[19] genotype combinations. The Canadian RVA strains were compared to the RVA strains present in the swine ProSystems RCE rotavirus vaccine. The comparison revealed multiple amino acid differences in the G and P antigenic epitopes, regardless of the G and P genotypes but specifically in the Canadian G3, P[13] and P[19] genotypes. Our study further contributes to the characterization of RVA's evolution and disease mitigation among swine, which may optimize target vaccine design, thereby minimizing RVA disease in this economically important animal population.
