In 2009,Mycobacterium bovisinfection was detected in a herd of 60 elk (Cervus elaphus) and 50 fallow deer (Dama dama) in Nebraska, USA. Upon depopulation of the herd, the prevalence of bovine tuberculosis (TB) was estimated at ∼71–75%, based upon histopathology and culture results. Particularly with elk, gross lesions were often severe and extensive. One year ago, the majority of the elk had been tested for TB by single cervical test (SCT), and all were negative. After initial detection of a tuberculous elk in this herd, 42 of the 59 elk were tested by SCT. Of the 42 SCT-tested elk, 28 were TB-infected with only 3/28 reacting upon SCT. After SCT, serum samples were collected from the infected elk and fallow deer from this herd at necropsy and tested by three antibody detection methods including multiantigen print immunoassay, cervidTB STAT-PAK, and dual path platform VetTB (DPP). Serologic test sensitivity ranged from 79 to 97% depending on the test format and host species. Together, these findings demonstrate the opportunities for use of serodiagnosis in the rapid detection of TB in elk and fallow deer.

ABSTRACT: Bovine tuberculosis (bTB) is an infectious disease caused by Mycobacterium bovis, affecting domestic animals, wild animals and humans. In captivity, for wild animals, bTB represents a risk to animal keepers and zoo visitors, in addition to the possibility of spreading the infection to domestic animals or through the trade of infected wild animals. Sambar (Cervus unicolor), red deer (Cervus elaphus) and fallow deer (Dama dama) from a safari park in the State of Rio Grande do Sul, Brazil, showed a clinical condition of dyspnea and weight loss. Some animals died and showed lesions suggestive of tuberculosis (LST), which were confirmed by histopathology. After the interdiction of the safari park by the state veterinary authorities, 281 deer were euthanized with the authorization of the “Instituto Brasileiro do Meio Ambiente e dos Recursos Naturais Renováveis” (IBAMA). Retropharyngeal and submandibular lymph nodes and viscera were collected from 21 animals, which were grown in Stonebrink medium for up to 90 days. After DNA extraction from the bacterial colonies, PCR was performed for targets flanking the region of differentiation 4 (RD4). Of the 21 samples, 14 (66.7%) presented LST with a granulomatous appearance, a whitish coloration, and caseous or calcified consistency, and seven samples (33.3%), showed no lesions. In the culture of 14 samples with LST, 13 (92.8%) presented bacterial growth compatible with M. bovis. In the cultivation of the seven samples without LST, four (57.1%) presented colonies compatible with M. bovis. PCR and DNA sequencing of the PCR amplicons detected as positive all the 17 (100%) bacteriological cultures suggestive of M. bovis, thus confirming the outbreak of bTB in deer. Decisions about positive tested and suspicious animals should be taken based on the evaluation of the risk of transmission to the rest of the zoological animals, animal welfare, conservation considerations and, the zoonotic potential of this pathogen.

The Relationship

The ultimate pH value of meat (measured at approx. 24 hours post slaughter) gives information about the technological quality, i.e. shelf life, colour, water-holding properties and tenderness and is a direct consequence of muscle glycogen (energy) levels at slaughter. It may therefore also indicate whether or not the animal has been exposed to stressful energy depleting events prior to slaughter. In the present study, 141 animals (130 red deer (Cervus elaphus) and 11 fallow deer (Dama dama) were included to investigate the relationship between ultimate pH and residual glycogen concentration in red deer and fallow deer M. longissimus. In addition, the muscle glycogen content and ultimate pH values in three red deer muscles (Mm. triceps brachii, longissimus and biceps femoris) were studied. M. triceps brachii had higher ultimate pH and lower glycogen content compared with the other two studied muscles. The frequency of intermediate DFD (5.8≤ pH<6.2) was 5.4% in red deer M. longissimus, compared with 9.1% in fallow deer, while the frequency of DFD (pH≥ 6.2) was much lower in red deer (3.8%) than in fallow deer (54.5%). A curvilinear relationship between ultimate pH and total glucose concentration (glycogen and glucose) 30 min post slaughter in red deer and fallow deer M. longissimus was found. The relationship between muscle pH and lactic acid concentration however, was indicated to be linear. A significant variation in total glucose concentration at ultimate pH below 5.80 was observed, including values in the range from 18 to 123 mmol/kg wet tissue. It was concluded that further studies are needed to further explore the relationship between muscle glycogen content and technological and sensory quality attributes of meat from different deer species.Abstract in Swedish / Sammanfattning:Köttets pH-värde (mätt ca 24 timmar efter slakt) har stor betydelse för den teknologiska kvaliteten som t. ex. hållbarhet, färg, vattenhållande förmåga och mörhet. Glykogenförrådet (energinivån) i djurens muskulatur vid slakt är helt avgörande för köttets slutliga pH-värde. Därför kan pH-värdet också indikera om hanteringen av slaktdjur varit skonsam eller om stora mängder muskelenergi har förbrukats vid stress. I vår undersökning ingick 141 hjortar (130 kronhjortar (Cervus elaphus) och 11 dovhjortar (Dama dama) för att studera sambandet mellan köttets pH-värde och glykogeninnehållet i M. longissimus. Glykogeninnehåll och pH-värden i 3 muskler från kronhjort (Mm. triceps brachii, longissimus och biceps femoris) undersöktes också. M. triceps brachii hade högre pH-värde och lägre glykogeninnehåll jämfört med de två andra musklerna. Det var inte så stor skillnad i frekvensen av intermediär DFD (pH-värden mellan 5,8 og 6,2) mellan de två hjortarterna (5,4% för kronhjort och 9,1% för dovhjort), däremot var frekvensen av DFD (pH-värden över 6,2) mycket låg hos kronhjort (3,8%) jämfört med dovhjort (54,5%). Det fanns ett kurvlinjärt samband mellan slutligt pH-värde i köttet och total glukoskoncentration (glykogen + glukos) mätt i M. longissimus 30 min efter slakt för både kron- och dovhjort. Ett linjärt samband mellan pH-värde och koncentration av mjölksyra i M. longissimus kunde också visas. Vi fann en mycket stor varitation i glukoskoncentration (18−123 mmol/kg våtvikt) när köttets pH-värdet var 5,8 eller lägre. Det behövs fler undersökningar för att vidare klargöra sambanden mellan glykogeninnehåll i muskulaturen och teknologisk och sensorisk kvalitet i olika typer av hjortkött.

In The Wild

The evidence for deer (Cervidae) in ancient Egypt is reviewed briefly. The question of whether deer ever existed in the wild as an element of the Egyptian fauna, or were only known from rare exotic imports, cannot be conclusively answered yet. It is quite likely, however, based upon the records of the Egyptians themselves, that deer were native, whether naturally occurring or introduced. While the identification of the species depicted as the Persian Fallow Deer (Dama dama mesopotamica) is probably correct, the Barbary Red Deer (Cervus elaphus) remains a possibility.

June July

Cortisol levels were determined in seven 2.5-year-old male red deer (Cervus elaphus) and 8 yearling male fallow deer (Dama dama) after an acute intramuscular injection of 0, 10, or 40 international units (IU) of ACTH, administered in June, July, or August. In both species a highly significant increase in cortisol concentration was observed within the first hour after both doses of ACTH. At the end of the rapid cortisol elevation (60 min post ACTH) the response in both species was equal for the 10 and 40 IU doses. Average pretreatment levels were around 1–2 μg/100 mL; peak levels registered in red deer were around 10 μg/100 mL, and in fallow deer maximal concentrations reached around 8 μg/100 mL. Although all deer responded to ACTH, strong interindividual differences in intensity of cortisol elevation were detected. The extent of increase of blood cortisol levels in response to ACTH appears to be an evolutionary adaptation of various cervid species to their respective environmental conditions.

A simultaneous live/dead and acrosome staining, originally described for domestic mammals, was successfully applied on red deer (Cervus elaphus) and fallow deer (Dama dama) spermatozoa collected from the cauda epididymidis and vas deferens of shot stags. The staining is simple enough for routine application. Seven classes of spermatozoa were distinguished in the smears of frozen/thawed semen samples. Morphology, including cytoplasmic droplets, was evaluated as well. Percentage of live cells with intact acrosomes and with no other morphological aberrations might be a practical index of semen quality.

Lesion Morphology

Sections of tuberculous lesions from 23 elk ( Cervus elaphus nelsoni) and red deer ( Cervus elaphus elaphus), 12 fallow deer ( Dama dama), 10 sika deer ( Cervus nippon), and 30 cattle were examined and compared. Lesions were scored for caseous necrosis, mineralization, neutrophils, macrophages, giant cells, and acid-fast bacilli. Some differences in lesion morphology between the species were noted. Elk/red deer lesions had marked variation and often differed from bovine lesions in several characteristics; elk/red deer lesions usually had scattered peripheral mineralization rather than central mineralization and contained more neutrophils and fewer giant cells than did bovine lesions. Fallow deer lesions contained more giant cells but were otherwise indistinguishable from elk lesions. Sika deer lesions had more giant cells and fewer neutrophils than did lesions from cattle or other cervid species. Sika deer giant cells were larger and contained more nuclei than did giant cells in the other species.
