The passive protection afforded by the colostrum from cattle that were vaccinated prepartum with an inactivated combination vaccine against the bovine respiratory syncytial virus (BRSV) was evaluated after an experimental challenge of calves. Pregnant cows without or with a low ELISA and...

Background: The knowledge on bovine vaccines against respiratory viruses on bronchoalveolar fluid cells is scarce. Objective: To compare the effects of a commercial intranasal (IN) and intramuscular (IM) vaccine against bovine respiratory disease (BRD) complex viruses on bronchoalveolar fluid cells ...

Understanding the immune dynamics in the respiratory mucosa of calves is necessary for a good management of bovine respiratory disease. Immune dynamics in the respiratory mucosa in humans and experimental animals has been assessed by flow cytometric analysis of bronchoalveolar lavage fluid (BALF);...

Bovine dictyocaulosis is a pulmonary parasitic disease present in temperate countries, with potential important clinical and economic impacts. The Baermann technique is routinely used despite its low sensitivity in adult cows. Recently developed serological tests seem to offer better sensitivity,...

Utilising diagnostic tools in addition to the physical examination of the bovine patient often allows narrowing down differential diagnoses or moving from a tentative to a definite diagnosis. Cow-side evaluation of samples will yield useful information, and additional laboratory examination may be...

Background: Respiratory diseases are among the most common and expensive to treat diseases in camels with a great economic impact on camel health, welfare, and production. Bronchoalveolar lavage fluid (BALF) has been proven as a valuable sample for investigating the leukocyte populations in the...

In this study, nasopharyngeal swabs (Swab) and bronchoalveolar lavage fluids (BALF) were collected from 50 Japanese black cattle diagnosed with severe chronic pneumonia, and identification of the causative bacteria of pneumonia and its antibiotic susceptibilities were investigated. Mycoplasma bovis ...

Objectives: The main bacterial pathogens associated with Bovine Respiratory Disease (BRD) are Mannheimia haemolytica, Pasteurella multocida, Histophilus somni and Mycoplasma bovis. M. haemolytica is the main bacterial agent of BRD and has a considerable economic impact in cattle, especially in the...

We investigated bovine respiratory disease complex by collecting bronchoalveolar lavage fluid (BALF) for bacteriological and virological examinations from fattening cattle following their introduction from market, and monitored their treatment records for any subsequent history of medical...

Mycoplasma bovis is an important cattle pathogen affecting animal health, welfare, and productivity. The main disease syndromes are mastitis, pneumonia, and otitis media in young stock, as well as arthritis. Response to antibiotic treatment is poor and no effective vaccine is available....
