Genetic diversity and risk factor analysis of drug-resistant Escherichia coli recovered from broiler chicken farms.

A total of 38 Escherichia coli isolates were recovered from 120 samples collected from various sources of broiler chicken farms (n = 10 each) in Andhra Pradesh and Telangana states. Though the recovered E. coli isolates were found variably resistant to the tested antibiotics, all the tested isolates were susceptible to meropenem.

South Indian zebu dwarf cattle show higher natural resistance to tick infestation compared to crossbreds: preliminary observations.

The present study aimed to evaluate the influence of various factors on the host resistance of cattle against tick infestation in Kerala State, South India. The number of naturally infested semi-engorged female ticks present on the cattle was counted on a sample cattle population across the four regions of Kerala. Then, the animals were grouped based on the tick count.

Evaluation of oxidative stress in caprine anaplasmosis and effect of vitamin E-selenium in monitoring oxidative stress.

Caprine anaplasmosis is an economically important tick-borne rickettsial disease that affects goats all over the world. Microscopic examination of stained blood smears from 162 animals revealed inclusion bodies of Anaplasma spp. in 24 cases.

Canine microfilarial excretory/secretory protein-based antibody assay for the diagnosis of brugian filariasis in dogs.

Brugian filariasis is reported in dogs in Kerala, India. Antibody detection kits are not available worldwide, for detection of Brugian filariasis in dogs. A study was carried out to develop Indirect plate ELISA using excretory secretory antigen isolated from canine brugian microfilariae and compare the sensitivity and specificity with that of blood smear examination.

Utility of recombinant LipL41 based IgM and IgG ELISA in diagnosis of canine leptospirosis in an endemic area - a study from Kerala, India.

A study was undertaken to evaluate the relevance of detecting IgM and IgG antibodies in diagnosis of canine leptospirosis in Kerala, a southern state of India, which is endemic for the disease. A total of 205 blood (35 from healthy vaccinated, 30 from healthy unvaccinated and 140 from diseased dogs) and 151 urine samples (11 from healthy vaccinated and 140 from diseased dogs) were collected from three districts of Kerala, Thrissur, Palakkad and Kozhikode with high incidence of leptospirosis. Recombinant LipL41 protein was used as antigen and IgG and IgM based ELISAs were standardized.
