The Transmission of Strains in Dairy Herds in Different Housing Systems.

Cattle are frequent carriers of spp.; therefore, these bacteria may be transmitted to humans through meat or milk. spp.

Association between Enzootic Pneumonia-like Lung Lesions and Carcass Quality and Meat pH Value in Slaughter Pigs.

Although the prevalence of respiratory diseases in slaughter pigs ranges from 19% to 74% and continues to be an important concern for swine herds worldwide, only a few studies have investigated the relationship between respiratory disease and pork quality. The general aim of this study was to investigate associations between the prevalence and severity of enzootic pneumonia-like lesions in Polish slaughter pigs on different carcass and meat-quality characteristics at the animal and herd levels. The average prevalence of bronchopneumonic lungs with different degrees of lesions was 94.

The Enterotoxin Production and Antimicrobial Resistance of Strains Originating from Slaughter Animals.

The pathogenicity of animal-origin strains, including antimicrobial resistance and enterotoxigenicity, was determined in this study. Overall, 149 isolates originating from cattle, swine and poultry were tested. The antimicrobial resistance profiles were examined by the diffusion disk method.

The Effect of Different Extenders on the Quality Characteristics of European Red Deer Epididymal Sperm Stored at 5 °C.

The aim of this study was to evaluate the effect of different extenders on the quality of European red deer epididymal sperm stored at 5 °C. Epididymal spermatozoa were collected post mortem from 10 stags and diluted with three extenders (Bovidyl®, BoviFree®, and BioXcell®) and stored at 5 °C. Sperm motility (TMOT), motility parameters (system CASA), plasma membrane integrity (SYBR-14+/PI−), acrosomal membrane integrity (FITC-PNA−/PI−), mitochondrial activity (JC-1/PI), viability, and apoptotic-like changes (YOPRO/PI) were evaluated.

Effect of Mixed Invasions of and in Cattle on Milk Yield and Contents in Polish Dairy Farms.

Wide distribution of ecto- and endoparasites in cattle is a serious problem in the sustainability of a farm, due to the negative impact on animals' health and productivity. The aim of this study was to determine the presence of antibodies against and in udder milk samples and the comparison of milk yield and content of the basic components of milk in ELISA-positive and ELISA-negative cows. Milk samples were collected from 148 lactating cows from 3 herds.

Short communication: Occurrence and differentiation of Mycobacterium avium ssp. paratuberculosis (MAP) strains from milk of cows from herd with low prevalence of MAP.

Mycobacterium avium ssp. paratuberculosis (MAP) is an important pathogen responsible for the chronic progressive granulomatous enteritis known as paratuberculosis. None of the detection methods of MAP infection based on isolation of the bacterium is 100% sensitive or specific.

Antimicrobial Resistance and Virulence Properties of Spp. Originating from Domestic Geese in Poland.

A total of 240 samples were evaluated for the presence of spp. was found in 83.3% of the cecum contents samples and 52.

The Effect of subsp. Infection on the Productivity of Cows in Two Dairy Herds with a Low Seroprevalence of Paratuberculosis.

Paratuberculosis is a chronic, progressive enteritis of ruminants, caused by subspecies . It affects the productivity of infected dairy cows, causing a reduction in the daily milk yield and basic milk components. The aim of the study was to determine the effect of subspecies on the productivity of dairy cows in two herds.

Seroprevalence of Mycobacterium avium subsp. paratuberculosis infection in dairy herds in Zuławy, Poland.

Conducting serological analyses for Mycobacterium avium subsp. paratuberculosis (MAP) infections is one of the initial step towards evaluating the existing epizootic threat. The reported study was undertaken in order to investigate the seroprevalence of MAP in the area of Zuławy Wiślane, characterized by land conditions favourable for the survival of this mycobacterium in the environment.
