PREVALENCE OF TICKS IN BUFFALOES IN THE UPPER SINDH PAKISTAN

ABSTRACT Tick infestation is still a major economic dilemma for the dairy owners in Pakistan. The current study reports the prevalence and bionomics of tick in the areas of upper Sindh, Pakistan. The study was carried out to identify and to quantify variation in the prevalence of bovine tick infestation with respect to host (age and species) and area studied. Random sampling was used and 1600 samples of Kundi buffaloes from the different areas were selected from extensive management systems. Prevalence of bovine tick infestation did not differ signifi cantly (OR = 0.876; p>0.05) in Kundi (179/800; 24.75%) and Nili-Ravi buffaloes (172/800; 22.3%). Hyalomma was the major tick species (10.2%; 163/1600), followed by Rhipicephalus (5.6%; 99/1600). The prevalence of ticks in calves (< 1 year) was signifi cantly (p < 0.05) higher compare to the adult animals (1-2 years and > 2 year animals). However, the prevalence of tick infestation was not associated (p > 0.05) with the location of the district. Moreover, the results of the prevalence of the ticks in the studied area provide the better understanding for evolving the strategic and tactile control of ticks in local breeds of dairy animals in the Sindh province

Babesiosis: Current status and future perspectives in Pakistan and chemotherapy used in livestock and pet animals

Babesiosis is a protozoal disease affect livestock and pet animals such as cattle, buffaloes, sheep, goats, horses, donkeys, mules, dogs, and cats. It causes severe economic losses in livestock as well as in pet animals. A large number of dairy animals are imported in order to fulfill the demands of milk, milk, meat and its products. In addition, different pet animals are transported from Pakistan to various parts of the world, therefore, it is important to identify the current status and distribution of babesiosis throughout Pakistan in order to control the disease and draw attention for future research, diagnosis, treatment and control of this diseases. No work has been done on a complete review on up-to-date on blood protozoal disease burden in Pakistan. This article will provide about the complete background of babesiosis in ruminants, equines and pet animals, its current status, distribution, vectors in Pakistan and allopathic and ethnoveterinary treatments used against babesiosis. Babesiosis may be subclinical (apparently normal) and may be clinical with acute to chronic disease and sometimes fatal. Babesia is found and develops inside the erythrocytes (red blood cells). Clinically, it causes fever, fatigue, lethargy, pallor mucus membranes, malaise, cachexia, respiratory distress, jaundice, icterus, hemolytic anemia, hemoglobinuria, lymphadenopathy, chollangocytitis, hepatomegaly, and splenomegaly. Chemotherapy for babesiosis includes Imidocarb dipropionate, Diaminazine aceturate Atovaquone and Bupravaquone, Azithromycin, Quinuronium sulfate and Amicarbalidesio-thionate are most widely used. Supportive therapy includes multivitamins, fluid therapy, antipyretics intravenous fluids, and blood transfusions are used if necessary. In addition, there are certain ethnoveterinary (homeopathic) ingredients which having anti-babesial activity. As the resistance against these drugs is developing every day. New more specific long-lasting drugs should be developed for the treatment of Babesiosis. Further studies should be done on disease genome of different species of Babesia for vaccine development like malarial parasites

Effect of Temperature and Storage Time on DNA Quality and Quantity from Normal and Diseased Tissues

DNA extraction and purification is an initial step for authentic results in advance molecular biology, therefore DNA degradation is unavoidable. The aim of present study is to investigate the DNA quality and quantity in terms of shorter time preservation with normal and diseased tissue, therefore tissues of normal (n = 18) and diseased (n = 18) liver, lung and heart was collected from goat after slaughtered. For DNA extraction Gene JET Genomic DNA Purification Kit protocol was followed, then stored at -20 oC and -04 oC temperatures for 24hrs and 48hrs period of time. The concentration and purity of the extracted DNA were measured with Spectrophotometer and purity confirmed at an absorbance ratio of 260 or 280. It was observed that at a -20 oC temperature for 24hours the concentration of DNA yield was numerically higher than at -04 oC temperature for tissue stored at 48hrs, whereas absorbance was higher, however in normal tissues in contrast with diseased the concentration and absorbance of DNA was somehow same at -20 and -04 oC but different in storage time. On the basis of these findings, it was concluded that time elapsed between sampling with the storage condition and with normal or diseased samples for DNA extraction will largely depend on the experiment. If tissue preservative conditions and sampling are appropriate, storage time will not be a factor at least for short storage periods

Estrus response and fertility rate in Kundhi buffaloes following estrus synchronization in breeding season

The aim of the present study was to compare the effect of two estrus synchronization treatments i.e., Ovsynch alone and Ovsynch plus Controlled Internal Drug Release (CIDR), on the occurrence of estrus and conception rate in Kundhi buffalo during breeding season in Pakistan. Forty Kundhi buffaloes were randomly selected and were divided into three groups; Group A (n=16; Ovsynch) received 2 mL GnRH intramuscularly (i/m) on day 0 and 9. On day 7, 5 mL prostaglandin F2 and #945; (PGF2 and #945; analogue) was administered through i/m route. The buffaloes of Group B (n=17; Ovsynch+CIDR) received 2 mL GnRH on day 0 along with implantation of CIDR. On day 7, the CIDR was removed, and 5 mL PGF2 and #945; analogue was injected through i/m route. A second dose of GnRH was administered through i/m route after 48 h of PGF2 and #945; inj. in both groups. Group C (n=7; control) received 2 mL normal saline through i/m route on day 0, 7 and 9. The buffaloes of all three groups were artificially inseminated twice (12 h and 24 h after the second GnRH inj.) using frozen-thawed semen. Estrus response differed significantly (P<0.05) among the groups. The animals of Group B (76.47%) showed superior estrus response as compared to others. Higher conception rate (52.94%) was observed in the animals of Group B; however, the difference was not significant. In conclusion, Ovsynch+CIDR causes to occur better estrus response and conception rate as compared to Ovsynch alone in Kundhi buffaloes during breeding season.

Ameliorative effects of supranutritional selenium on TLR‐4‐NF‐kB‐TNF‐α‐mediated hepatic oxidative injury and inflammation in goats fed high concentrate diet

Abstract We examined whether surplus dietary selenium (Se) supply could alleviate high concentrate (HC) diet‐induced hepatic oxidative stress (OS) and inflammation. Eighteen young goats were distributed into three groups; were fed low (LC, concentrate: forage; 35: 65), high concentrate (HC, 65: 35), or Se‐supplemented HC (HCSe, 65: 35 + 0.5 mg Se kg−1 diet) diets for 10 weeks. Short chain fatty acids, OS markers and immunoinflammatory genes expressions were assessed through gas chromatograph, kits, and RT‐qPCR, respectively. Compared with LC, HC diet increased (p < .05) colonic and serum lipopolysaccharide (LPS) levels and induced hepatic oxidative injury by increasing (p < .05) malondialdehyde (MDA) levels and decreasing (p < .05) activities of glutathione peroxidase, superoxide dismutase, and catalase. HC diet altered hepatic mRNA expressions of toll‐like receptor‐4 (TLR‐4), cluster of differentiation‐14 (CD‐14), tumor necrosis factor‐α (TNF‐α), TNF receptor‐associated factor‐6 (TRAF‐6), nuclear factor kappa B (NF‐κB), interleukin‐1β (IL‐1β), IL‐10, IL‐13, LPS‐binding protein (LBP), serum amyloid A (SAA), α‐acid glycoprotein (AGP), and albumin (ALB). Conversely, extra‐Se supply lowered LPS and attenuated antioxidant status and inflammation in liver. In conclusion, HC diet induced oxidative lesions and TLR‐4 pathway‐mediated inflammation, whereas supranutritional Se alleviated oxidative and inflammatory lesions through TLR‐4 pathway regulation in goat liver
