The wolf spider Lycosa terrestris (Araneae: Lycosidae) is a well known arthropod containing toxic compounds. It has significant predatory potential in addition to its uses in medicinal and insecticidal formulation. Current investigations were aimed to extract and partially characterize the venom of L. terrestris and the susceptibility tests to evaluate antibacterial potential of venom supernatant and venom pellets against four pathogenic bacterial strains i.e., Gram negative Acinetobacter sp. and Pasteurella sp. and Gram Positive Staphylococcus sp. and Streptococcus sp. Results of this study revealed that the venom of L. terrestris contained six relatively high molecular weight peptides ranging from 125 kDa to 35 kDa. Moreover, results of the susceptibility test confirmed the bacteriostatic action of venom supernatant against aerobic Gram negative Acinetobacter sp. in dose dependent manner. A reduced trend of bacteriostatic inhibition was also observed for venom pellets against Acinetobacter sp

Canine diseases, particularly caused by tick-borne hepatozoons are responsible for high morbidity and mortality and are the reason for attracting significant focus. The current study was aimed to survey the occurrence of H. canis in domesticated and stray dogs of Jhang city (Punjab) with its molecular identification. For this, blood samples from 300 dogs (n=200 domesticated; n=100 stray) were collected and assayed through PCR for the detection of H. canis supported by sequencing analysis. The results demonstrated, 15.66% (47/300) of samples positive for H. canis. A significantly (P<0.05) higher occurrence of H. canis was observed in stray dogs (27%) than domesticated dogs (10%). Evaluation of the various risk factors showed that the age, sex, breed, dog category (domestic or stray), body coat, environmental settings (rural or urban) and ectoparasitic infestation were significantly (P < 0.05) associated with the occurrence of infection. The phylogenetic analysis of the PCR confirmed specimens revealed a very close homology of the detected strains with the ones diagnosed earlier in China and Malta. It was concluded that present moderate prevalence of H. canis among the dog populations in the area of Jhang may rise with stray dogs being most vulnerable hosts and potential source of vectors spread. © 2021 Friends Science Publishers
