Management of bovine brucellosis in organized dairy herds through the identification of risk factors: A cross-sectional study from Karnataka, India.

Background And Aim: Brucellosis is an infectious disease caused by species. This study aimed to identify the risk factors associated with bovine brucellosis seropositivity in organized dairy farms to control the disease in unvaccinated adult bovine herds in Karnataka, India.

Materials And Methods: In total, 3610 samples (3221 cattle and 389 buffaloes) were subjected to parallel testing using the Rose Bengal plate test and protein G-based enzyme-linked immunosorbent assay, followed by analyses of animal- and farm-level epidemiological datasets to identify the risk factors.

Assessment of Immune Responses to Rabies Vaccination in Free-Ranging Dogs in Bengaluru, India.

Rabies is a fatal encephalomyelitis mainly transmitted to humans and other animals by rabid dog bites. Hence, vaccination programs are being instituted for the control of rabies in dogs. Though stray dogs have been vaccinated for years under various programs initiated for control of the disease, the effectiveness of these programs can be ascertained only by assessing the immunity of these dogs.

Developments in Rabies Vaccines: The Path Traversed from Pasteur to the Modern Era of Immunization.

Rabies is a disease of antiquity and has a history spanning millennia ever since the first interactions between humans and dogs. The alarming fatalities caused by this disease have triggered rabies prevention strategies since the first century BC. There have been numerous attempts over the past 100 years to develop rabies vaccineswith the goal of preventing rabies in both humans and animals.

Seroprevalence and risk factors for brucellosis in small ruminant flocks in Karnataka in the Southern Province of India.

Background And Aim: Brucellosis is a zoonotic disease of high economic and public health importance in large and small ruminant populations worldwide. A cross-sectional study was conducted to determine the seroprevalence and risk factors of brucellosis in small ruminants in organized farms in the southern region of India.

Materials And Methods: Farms exclusively rearing sheep and goats were selected based on the number of animals (small, medium, or large) and the location of the farm (urban, periurban, or rural).

Prevalence and antibiotic susceptibility of and isolated from ovine respiratory infection: A study from Karnataka, Southern India.

Background And Aim: Respiratory infection due to and are responsible for huge economic losses in livestock sector globally and it is poorly understood in ovine population. The study aimed to investigate and characterize and from infected and healthy sheep to rule out the involvement of these bacteria in the disease.

Materials And Methods: A total of 374 healthy and infected sheep samples were processed for isolation, direct detection by multiplex PCR (mPCR), and antibiotic susceptibility testing by phenotypic and genotypic methods.

Spatial seroprevalence of bovine brucellosis in India-A large random sampling survey.

Brucellosis caused by Brucella spp. is an important zoonosis and constitutes a serious public health hazard. In India, the disease is increasingly prevalent among bovine population with high zoonotic potential and negative impact on national economy.

Fluorescence polarization assay: Diagnostic evaluation for porcine brucellosis.

Brucellosis in pigs, caused by the bacterium Brucella suis, is an important zoonotic infection. In the present study, fluorescence polarization assay (FPA) was standardized and compared with indirect enzyme linked immunosorbent assay (iELISA) and competitive ELISA (cELISA) for diagnosis of porcine brucellosis. Test performances were evaluated using representative panel (n = 100), samples from swine brucellosis outbreak (n = 300), samples from brucellosis suspected animals (n = 291) and sera samples from apparently healthy animals (n = 1121).

Serological and molecular analysis for brucellosis in selected swine herds from Southern India.

Background: Swine brucellosis is a zoonotic disease caused by Brucella suis. The study describes the occurrence of brucellosis in two organized piggeries in Southern India.

Methods: A total of 585 serum samples comprising 575 from pigs and 10 from animal handlers were collected and tested by serological tests and PCR.

Assessment of fluorescence polarization assay: a candid diagnostic tool in Brucella abortus strain 19 vaccinated areas.

Brucellosis caused by the bacteria of the genus Brucella is an important zoonosis and constitutes a serious public health hazard. Brucellosis is diagnosed mainly by the Rose Bengal plate test and indirect ELISA, both of which have poor specificity because false positive serological reactions occur when screening animals that have been vaccinated with B. abortus S19.

Lateral flow assay for brucellosis testing in multiple livestock species.

Lateral flow assay (LFA) for brucellosis was standardized and evaluated. The test showed high diagnostic sensitivity, specificity and accuracy for diagnosis of brucellosis in bovines, small ruminants and swine. The study emphasized the importance of LFA as a useful, rapid, and easy-to-perform tool for the testing of brucellosis.

Genotyping of Indian antigenic, vaccine, and field Brucella spp. using multilocus sequence typing.

Introduction: Brucellosis is one of the most important zoonotic diseases that affects multiple livestock species and causes great economic losses. The highly conserved genomes of Brucella, with > 90% homology among species, makes it important to study the genetic diversity circulating in the country.

Methodology: A total of 26 Brucella spp.

Draft Genome Sequence of Brucella abortus S99: Designated Antigenic Smooth Reference Strain Used in Diagnostic Tests in India.

Brucella abortus strain S99 is widely used for the preparation of colored, plain, recombinant and smooth lipopolysaccharide antigens for the preparation of Brucella diagnostic kits. The genome of this strain was sequenced and the length of the genome was 3,253,175 bp, with 57.2% G+C content.

Draft Genome Sequence of Brucella melitensis Strain ADMAS-G1, Isolated from Placental Fluids of an Aborted Goat.

Here, we report the draft genome sequence and annotation of the Brucella melitensis strain designated ADMAS-G1, isolated from placental fluids of an aborted goat. The length of the genome is 3,284,982 bp, with a 57.3% GC content.

Molecular characterization of Streptococcus agalactiae and Streptococcus uberis isolates from bovine milk.

Streptococci are one among the major mastitis pathogens which have a considerable impact on cow health, milk quality, and productivity. The aim of the present study was to investigate the occurrence and virulence characteristics of streptococci from bovine milk and to assess the molecular epidemiology and population structure of the Indian isolates using multilocus sequence typing (MLST) and pulsed-field gel electrophoresis (PFGE). Out of a total of 209 bovine composite milk samples screened from four herds (A-D), 30 Streptococcus spp.

Histone H3K14 and H4K8 hyperacetylation is associated with Escherichia coli-induced mastitis in mice.

Mastitis is a multietiological complex disease, defined as inflammation of parenchyma of mammary glands. Bacterial infection is the predominant cause of mastitis, though fungal, viral and mycoplasma infections also have been reported. Based on the severity of the disease, mastitis can be classified into subclinical, clinical and chronic forms.
