In order to identify the enteric pathogens involved in cases of neonatal calf diarrhoea, a series of tests are performed on faecal samples collected at <em>post mortem</em> from affected calf carcases or submitted by veterinary practitioners from clinical cases.</p> <p>Approximately 1800 such faecal samples were examined in DAFM laboratories in 2018 (Table <a href="bovine-neonatal-enteritis.html#tab:neotabuno">4.1</a>).

Calves are most susceptible to rotavirus enteritis up to three weeks of age. Adult animals are the primary source of rotavirus infection for neonatal calves. The severity of clinical signs depends on several factors including the age of the animal and the immune status of the calf, the latter depends on the absorption of colostral antibodies immediately after birth. Rotavirus targets villi in the upper small intestine causing shortening and fusion of such villi, this results in malabsorption and leads to diarrhoea. Death may ensue due to acidosis, dehydration and starvation.</p> <div class="figure" style="text-align: center"><span id="fig:neofiguno"></span> <img src="Surveillance_files/figure-html/neofiguno-1.png" alt="Bovine Neonatal Enteritis.

Affected calves excrete large numbers of oocysts which are highly resistant and can survive in the environment up to several months under favourable conditions. Transmission between animals is by faecal-oral route, often via a contaminated environment. Control of the parasite is best achieved by strict maintenance of good calf housing hygiene practices and avoiding mixing animals of different ages. Ammonia-based disinfectants are most effective. The prophylactic use of drugs such as halofuginone lactate may also be useful. In addition to causing disease in animals, <em>Cryptosporidium spp.</em> has the potential to cause zoonotic disease especially in immunocompromised humans; therefore farm workers should take appropriate hygiene precautions when handling calves.</p> <p><br><br></p> </div> <div id="coronavirus-enteritis" class="section level3"> <h3><span class="header-section-number">4.1.3</span> Coronavirus enteritis</h3> <p>Calves are most susceptible to coronavirus enteritis between one and three weeks of age.

These strains of E. coli preferentially colonise the lower small intestine and produce toxins that cause secretion of water and electrolytes from the intestinal mucosa, resulting in rapid dehydration. The percentage prevalence of <em>E. coli</em> K99 would likely be higher if testing for this enteric pathogen was restricted to animals younger than one week old.</p> <p><br><br></p> </div> <div id="salmonella-dublin" class="section level3"> <h3><span class="header-section-number">4.1.5</span> <em>Salmonella</em> Dublin</h3> <p><em>Salmonella enterica</em> subsp.<em>enterica</em> serovar Dublin (<em>Salmonella</em> Dublin) is the most common <em>Salmonella</em> serotype that affects calves in the Republic of Ireland and was isolated in 0.91 <em>per cent</em> of neonatal faecal samples cultured in 2018. The relative frequency of detection of <em>Salmonella</em> Dublin from such cases has fallen significantly over the past decade from 3.4 <em>per cent</em> in 2011 to 0.9 <em>per cent</em> in 2018 (Figure <a href="bovine-neonatal-enteritis.html#fig:neofigdos">4.4</a>). It is not clear why this has occurred. <em>Salmonella</em> Dublin infection has a number of clinical presentations in neonatal calves including acute enteritis, osteomyelitis and septicaemia/systemic disease. <em>Salmonella</em> enteritis is characterised by watery mucoid diarrhoea with presence of fibrin and blood. While Salmonella can cause diarrhoea in both adult cattle and calves, infection is more common and often more severe in calves from 10 days to 3 months old. In addition, calves can shed the organism for variable periods of time and/or intermittently depending on the degree of infection (carrier state).</p> <p><br><br></p> <style> div.blue { background-color:#e6f0ff; border-radius: 5px; padding: 20px;} </style> <div class="blue"> <p>The basic principles for the prevention and control of neonatal enteritis are enhancing host immunity and reducing the load of enteric pathogens in the environment.

Thereafter, appropriate nutrition of young calves, including diarrhoeic calves, is essential. Calves should be grouped according to age on dry clean bedding and avoiding high stocking density. There should be good hygiene practices including appropriate disinfection between batches and rapid isolation and treatment of sick calves.</p> <p>Colostral and milk antibodies against certain bacterial and viral enteric agents can be enhanced by vaccination of the cows during the dry period (passive immunisation).</p> </div> <p><br><br></p> </div> <div id="campylobacter-jejuni" class="section level3"> <h3><span class="header-section-number">4.1.6</span> <em>Campylobacter jejuni</em></h3> <p><em>C. jejuni</em> was found in almost 8.88 <em>per cent</em> of neonatal calf faecal samples tested in 2018.
