Proteinograma sérico de bezerros recém-nascidos alimentados com colostro de vacas com mastite

The aim of this study was to evaluate the serum protein concentration in newborns fed with colostrum derived from healthy cows (n = 10), cows with subclinical mastitis (n = 10) and cows with clinical mastitis (n = 10). 30 Holstein cows were assigned to their respective groups according to macroscopic examination of colostral secretion, somatic cell count, CMT and presence of bacteria in colostrum samples. Blood samples of the calves were collected immediately after birth, at 24 and 48 hours after ingestion of colostrum. The total protein was measured by the biuret method and the concentrations of immunoglobulin A (IgA), immunoglobulin G (IgG), transferrin, albumin and haptoglobin was determined by sodium dodecyl sulphate-polyacrylamide gel electrophoresis (SDS-PAGE). No differences were obser- ved amongst groups in the concentrations of albumin, total protein and IgA. In animals from cows with subclinical and clinical mastitis haptoglobin concentrations were higher than those of healthy animals. The concentrations of IgG and transferrin were significantly lower in calves from cows with mastitis. We concluded that the ingestion of colostrum from infected and uninfected glands from cows with mastitis (GII e GIII) is unlikely to be an important contributor to the high rate of failure of passive transfer of immunoglobulins in calves.

Hipotireoidismo em cães: revisão

Hypothyroidism is one of the most frequent endocrinopathies in dogs, affecting preferentially middle-aged, pure breed animals. Associated clinical signs are variable and often non-specific, including metabolic, dermatological or cardiovascular alterations. The main laboratorial findings are non-regenerative anemia and hypercholesterolemia. Hyponatremia and an increase in alanine transferase and alkaline phosphatase activities can also be observed with lower frequency. There are specific diagnostic tests that can be used to help diagnose hypothyroidism, and those should be interpreted in the light of the animal´s clinical symptoms. The levels of thyroxine stimulating hormone (TSH) and both free and total thyroxine (T4) are the most used hormonal tests. It is important to differentiate between hypothyroidism and the euthyroid sick syndrome, a condition that may be caused by severe diseases such as hyperadrenocorticism and lead to decreased TSH and T4 levels as well. Levothyroxine sodium is the standard treatment. The main objective of this paper is to review hypothyroidism in dogs, since this is a very common disease in small animal clinics, but with difficult diagnosis.

Microbiologic characterization of equine mastitis

Mastitis occurrence in mares is low if compared to other livestock species. The microorganisms often isolated and detected in milk and mammary gland secretions of mares are Streptococcus beta-haemolytica, Staphylococcus spp., Pseudomonas aeruginosa, Actinobacillus spp., and enterobacter. The present experiment was designed to evaluate the main microorganisms present in the milk of healthy mares and having a mammary infection. One hundred and ten mammary glands from 55 lactating mares were analyzed, ranging from 15 to 150 d post-partum. The mastitis diagnostic was performed through analysis of the milk via the screened test of the mug with dark background (Tamis), mammary gland inflammation and/or systemic signs. The subclinical mammary gland infection was characterized via the California Mastitis Test (CMT). From the 55 lactating mares, 2 (3.64%) had clinical mastitis. Following the CMT, the mares presented: 13 (23.60%), 7 (12.72%), and 12 (21.88%) scores from 1+, 2+, and 3+, respectively. From the 110 mamary glands were analysed, in 47 (85.45%) of these samples strains of microorganisms were isolated. In summary, results from our experiment suggest a low occurrence of clinical mastitis in lactating mares.
