There is a wide range of nematode species of zoonotic potential
that can infect pet dogs. The present study was conducted to detect
nematode infestation in pet dogs in Lahore. Two types of nematodes
were identified (Toxocara canis and Ancylostoma caninum) in fecal
samples of 300 pet dogs from January 2011 to June 2011 by various
techniques . The prevalence of T.canis was 11.33% and 8.33% for
A.caninum by Direct Smear Method. By Flotation Technique prevalence
of T.canis was 14.33% and 12.3% for A.caninum and by Sedimentation
Technique the prevalence of T.canis and A.caninum was 11.66% and
10% respectively. To investigate the effect of physical factors on
prevalence of nematodes, month-wise mean temperature and mean
monthly relative humidity was also analysed. The results of study
revealed that temperature has a positive relationship with the
prevalence of infection. But the percent prevalence of both types
of nematodes did not show any direct relation with relative
humidity.As pet dogs are the reservoir of transmission of diseases
to humans specially children, so there is a need to control of
nematode infections by establishing hygienic conditions and regular
clinical examination
Invertase ( -D (fructofuranosidase, EC 3.2.1.26) is one of the
important commercial enzymes used in food industry. It catalyses
the reaction of detachment of the terminal non-reducing
-D-fructofuranoside residue in -D-fructofuranosides. A wide range
of microorganisms produce Invertase and can, thus, utilize sucrose
as the only carbon source and as inducer of such enzyme. Food
processing industry produces an enormous amount of carbohydrate
wastes, which pose increasing disposal costs and environmental
challenges. Beside their pollution and hazardous aspects, these
organic wastes are rich in biodegradable materials, and have
potential to be used as suitable substrates for biotechnological
productions. The present study was planned to produce Invertase
from indigenous wastes including carrot and potato peels, as
substrates for Aspergillus species through solid state fermentation
(SSF). For this purpose, five different species were screened.
Higher activities of Invertase were produced by Aspergillus niger
on carrot peels and A.terreus on potato peels. Hence this study may
helpful to produce, purify and characterize the enzyme by using the
food processing wastes.
