Importance of old bulls: leaders and followers in collective movements of all-male groups in African savannah elephants (Loxodonta africana)

2020-09-03 - Exeter, United Kingdom. Connie R. B. Allen, Lauren J. N. Brent, Thatayaone Motsentwa, Michael N. Weiss & Darren P. Croft

By analysing leadership patterns of all-male African savannah elephant traveling groups along elephant pathways in Makgadikgadi Pans National Park, Botswana, we found that the oldest males were more likely to lead collective movements. Our results challenge the assumption that older male elephants are redundant in the population and raise concerns over the biased removal of old bulls that currently occurs in both legal trophy hunting and illegal poaching.

Mycobacterium tuberculosis in Wild Asian Elephants, Southern India

2017-02-22 - Trichur, India.

We tested 3 wild Asian elephants (Elephas maximus) in southern India and confirmed infection with Mycobacterium tuberculosis, an obligate human pathogen, by PCR and genetic sequencing. Our results indicate that tuberculosis may be spilling over from humans (reverse zoonosis) and emerging in wild elephants.

Rapid screening for Mycobacterium tuberculosis complex in clinical elephant trunk wash samples.

2017-01-28 - , United States. Magnuson RJ1, Linke LM2, Isaza R3, Salman MD2.

Ninety-nine clinical trunk wash samples obtained from 33 elephants were utilized to validate three molecular extraction techniques followed by a polymerase chain reaction for detection of M. tuberculosis. Diagnostic sensitivity and specificity were estimated compared to culture. Kappa coefficients were determined between molecular results and various culture categories and serological test results.

Hereditary Factor VII Deficiency in the Asian Elephant (Elephas maximus) Caused by a F7 Missense Mutation.

2017-01-24 - Pennsylvania, United States. Lynch M1, McGrath K2, Raj K3, McLaren P4, Payne K5, McCoy R4, Giger U3.

A wild-caught, 41-yr-old male Asian elephant ( Elephas maximus ) without an apparent increased bleeding tendency was consistently found to have prolonged prothrombin times (PTs, mean = 55±35 s) compared to 17 other elephants (PT=10±2 s). This elephant´s partial thromboplastin times (PTT) fell within the normal range of the other elephants (12-30 s). A prolonged PT in the presence of a normal PTT suggests disruption of the extrinsic pathway via deficiency of coagulation factor VII (FV...

Behavioral changes in female Asian elephants when given access to an outdoor yard overnight.

2016-04-29 - New York, United States. Powell DM, Vitale C.

A study was conducted at the Bronx Zoo to determine whether providing elephants with access to an outdoor corral at night had any significant effects on behavior, use of space, and use of a sand corral. Activity budgets for three female Asian elephants were compared when the subjects were housed indoors overnight and when they were given access to an outdoor yard overnight. Observations were recorded via infrared video cameras between the hours of 1900 and 0700 during the months of July-Septembe...

Blood Compatibility Testing in Asian Elephants Using an Indirect Antiglobulin Technique to Improve Captive Breeding Success. Asian Journal of Animal and Veterinary Advances

2015-11-17 - Chiang Mai, Thailand. Pakkanut Bansiddhi, Preeyanat Vongchan, Achiraya Satityuenyong, Khajohnpat Boonprasert, Sittidet Mahasawangkul, Ronnachit Roongsri, Janine L. Brown and Chatchote Thitaram

The aim of this study was to examine blood compatibility in Asian elephants using the indirect antiglobulin technique, for use as a breeding management tool to reduce the risk of elephant fetal loss. Forty-four blood samples collected from 22 female and 22 male elephants were subjected to standard tube cross-matching tests and examined for macroscopic and microscopic agglutination reactions.

First Fatality Associated with Elephant Endotheliotropic Herpesvirus 5 in an Asian Elephant: Pathological Findings and Complete Viral Genome Sequence

2014-09-10 - , United States. Wilkie, Davison, Kerr, Stidworthy, Redrobe, Steinbach, Dastjerdi, Denk

Here, we report the pathological characteristics of the first fatality linked to EEHV5 infection, and describe the complete viral DNA sequence. Gross post-mortem and histological findings were indistinguishable from lethal cases previously attributed to other EEHV genotypes, and the presence of characteristic herpesviral inclusions in capillary endothelial cells at several sites was consistent with the diagnosis of acute EEHV infection.

DETECTION OF ELEPHANT ENDOTHELIOTROPIC HERPESVIRUS INFECTION AMONG HEALTHY ASIAN ELEPHANTS (ELEPHAS MAXIMUS) IN SOUTH INDIA.

2014-01-31 - Bethesda, United States. Stanton JJ, Nofs SA, Zachariah A, Kalaivannan N, Ling PD.

We used previously validated EEHV-specific quantitative real-time PCR assays to detect subclinical EEHV infection in three regionally distinct Asian elephant cohorts, totaling 46 in situ elephants in South India, during October and November 2011. Using DNA prepared from trunk washes, we detected EEHV1, EEHV3/4, and EEHV5 at frequencies of 7, 9, and 20% respectively. None of the trunk washes was positive for EEHV2 or 6. At least one EEHV species was detectable in 35% (16/46) of the samples that w...

Albuquerque zoo"s elephant herd to expand

2013-08-10 - Albuquerque, United States.

Zookeepers say blood tests indicate that Rozie the elephant´s calf will likely be a girl. The window for her giving birth is between August and November, but keepers suspect the calf may come in mid-September. The BioPark´s elephant manager, Rhonda Saiers, says the zoo is excited about the potential of adding another female to the multigenerational herd. Still, there´s a chance the gender test could be wrong.
