Take Home Message  Use of intramammary antimicrobial dry cow treatment (DCT) is fundamental for effective mastitis control but even with the use of DCT, about 2530% of cows may have quarters that maintain chronic intramammary infections across the dry period  Quarters with chronic intramammary infections have 4 times increased risk of having clinical mastitis in the current lactation as compa...

Spring calving Angus and Angus x Hereford multiparous cows were utilized to determine the effects of intramammary treatment with penicillin G procaine (200,000 IU) and novobiocin (400 mg) at the time of weaning on udder health and calf growth after the subsequent calving. Cows were stratified by age and breed and assigned randomly to receive intramammary treatment (n = 99) at weaning or as untr...

The production of luteal oxytocin in ewes, resulting from the intrajugular injection of 200 micrograms of PGF2 alpha, could be determined by the increase in intramammary pressure. This simple indirect method of measuring the activity of the corpus luteum enabled easy detection of renewed post-partum ovulation or the onset of pregnancy. The response was monitored every two days between Days 0 an...

The objectives of this study were to determine 1) the effect of intramammary infection on calf weaning weight, milk somatic cell count, and milk composition, and 2) the effect of parity on percentages of infected cows, infected quarters, and blind quarters. The number of infected quarters, milk somatic cell counts, milk components, and intramammary infection were studied at weaning in 164 beef ...

Mastitis in dry cows has traditionally been controlled with long-acting intramammary antibiotic formulations. However, the widespread use of antibiotics, particularly for prophylactic application, is likely to be restricted in the future. As a consequence, there is now a growing requirement for effective alternatives to prevent mastitis. A bismuth-based, intramammary teat seal has recently been...

A 22-year-old man was referred to our cardiology department for investigation of hypertension. At presentation his blood pressure was 170/100 mmHg in both arms, and heart rate was 74 beats/min. The pulses were equal over both upper extremities, but bilateral femoral and popliteal pulses were extremely weak and the dorsalis pedis and anterior tibial pulses were not palpable. His past history was...

background: the impact of positive intramammary lymph node (im ln) on the prognosis of patients with breast cancer has been debated for years; likewise, the standard management of patients with positive im ln remains unclear, especially when it is identified by preoperative imaging or by sentinel lymph node biopsy. the present study aims at reviewing the level of concurrent involvement of im ln...
