A pregnant female Cape giraffe (Giraffa camelopardalis giraffa) died from an unknown cause in the Aitana Zoo, Alicante, Spain. Neither clinical signs nor macroscopic lesions were observed at necropsy. The alimentary tract was removed and examined for parasites. A total of 2 724 nematodes were found, including Camelostrongylus mentulatus, Trichostrongylus axei, Ostertagia ostertagi, Teladorsagia circumcincta, Teladorsagia trifurcata, Marshallagia marshalli, Trichostrongylus vitrinus, Trichostrongylus colubriformis, Spiculopteragia asymmetrica and Trichuris giraffae. Only T. giraffae and C. mentulatus have been previously reported from giraffes. The other nematodes are common in mouflons, fallow and red deer, which can usually be found in the same paddock as the giraffes in Aitana Zoo. Although its occurrence is unusual in this host, C. mentulatus was the most abundant nematode in our giraffe. This parasite has been related to disease, and even death, in several wild ruminants.

Monitoring of gastrointestinal nematode parasites in ruminants (domestic and wild) is often based on fecal examination techniques, looking for excreted eggs and larval forms using morphological keys. These, are more available in domestic ruminants, in which helminths are widely studied, than in wild ruminants.  This study tried to provide certain morphological elements that will help to recognize the L3 larvae of Camelostrongylus mentulatus and Nematodirus spathiger that could parasite either domestic or wild ruminants. For that, we resorted first to the culture of L3 larvae from fecal samples taken from African antelopes, and second by the microscopic characterization of each isolated larval morphological pattern previously identified by sequencing of its internal transcribed spacer (ITS-2) regions of the ribosomal DNA. The results of different microscopic captured images showed that Camelostrongylus mentulatus larva is 16 intestinal cells that measuring approximately 820 µm length, ‎≈ 25 µm wide, and ‎≈ 47 µm for its sheath tail extension and by this be closer to Teladorsagia circumcincta characteristics.  For Nematodirus spathiger, it possesses 8 gut cells and measuring about 1020 µm long, ‎≈ 25 µm wide, and‎ ≈ 143 µm for its sheath tail extension with specific tail appendages. Have done this, we were able to get some clarifications on the morphology of the studied larvae, and we believe thus that this study will contribute to the establishment of morphological identification keys especially for parasitic nematodes of wild ruminants.

Mycoplasma Mycoides

Contagious agalactia (CA) is suspected when small ruminants show all or several of the following clinical signs: mastitis, arthritis, keratoconjunctivitis and occasionally abortion. It is confirmed following mycoplasma isolation or detection. The historical and major cause is Mycoplasma agalactiae which was first isolated from sheep in 1923. Over the last thirty years, three other mycoplasmas (Mycoplasma mycoides subsp. capri, Mycoplasma capricolum subsp. capricolum and Mycoplasma putrefaciens) have been added to the etiology of CA because they can occasionally cause clinically similar outcomes though nearly always in goats. However, only M. agalactiae is subject to animal disease regulations nationally and internationally. Consequently, it makes little sense to list mycoplasmas other than M. agalactiae as causes of the OIE-listed CA when they are not officially reported by the veterinary authorities and unlikely to be so in the future. Indeed, encouraging countries just to report M. agalactiae may bring about a better understanding of the importance of CA. In conclusion, we recommend that CA should only be diagnosed and confirmed when M. agalactiae is detected either by isolation or molecular methods, and that the other three mycoplasmas be removed from the OIE Manual of Diagnostic Tests and Vaccines in Terrestrial Animals and associated sources.

During the first 250 miles (400 km) of spawning migration of Fraser River sockeye salmon (Oncorhynchus nerka) the free histidine content of the muscle, alimentary tract, and head+skin+bones+tail decreased to a small fraction of the initial value. A further decrease occurred in the levels of this amino acid in the alimentary tract during the subsequent 415-mile (657-km) migration to the spawning grounds, no change being observed with the other tissues. Comparatively small changes in free histidine were found with heart, spleen, liver, kidney and gonads during migration.

SummaryTwo shoulder blades with healed lesions found at the Mesolithic settlement Star Carr are described, one of an elk (Alces alces (L.)) and the other front red deer (Cervus elaphus L.). Their presence at the site throws light on the question of seasonal occupation, indicating that the site has been populated at least during winter time. In addition, some comments are made on the supposed lesions on the elk from High Furlong, Lancashire.

The Mediterranean Basin

Reassortment contributes to the evolution of RNA viruses with segmented genomes, including Bluetongue virus (BTV). Recently, co-circulation of natural and vaccine BTV variants in Europe, and their ensuing reassortment, were proposed to promote appearance of novel European BTV strains, with potential implications for pathogenicity, spread and vaccination policies. Similarly, the geographical features of the Mediterranean basin, which spans over portions of three continents, may facilitate the appearance of clinically relevant reassortants via co-circulation of BTV strains of African, Asian and European origins. In August–October 2017, BTV serotype 6 (BTV-6) was identified in young animals exhibiting classical clinical signs of Bluetongue (BT) at Israeli sheep and cattle farms. Sequencing and pairwise analysis of this Israeli BTV-6 isolate revealed the closest sequence homology of its serotype-defining Segment 2 was with that of South African reference BTV-6 strain 5011 (93.88% identity). In contrast, the other viral segments showed highest homology (97.0%–99.47% identity) with BTV-3, -4 and -9 of Mediterranean and African origins. Specifically, four viral segments were nearly identical (99.13%–99.47%), with Tunisian and Italian BTV-3 strains (TUN2016 and SAD2018, correspondingly). Together, our data suggest that Mediterranean co-circulation and reassortment of BTV-3 and BTV-6 drove the emergence of a novel and virulent BTV-6 strain

Several hundred vegetative and fertile specimens of Azolla Lam. have been recovered from the Paleocene Paskapoo Formation at the Joffre Bridge locality (Middle Tiffanian (Ti3) age) near Red Deer, Alberta. The spore complexes closely resemble those of the Paleocene A. stanleyi Jain & Hall, and the vegetative material is referred to that species. The specimens are unusually complete in that the remains of the fragile sporophyte are preserved, commonly with reproductive structures in place. Plants reaching up to 2.25 cm in length consist of alternately branched rhizomes bearing alternate, imbricate, sessile leaves. Leaves are ovate with entire margins, papillate surfaces, and a single midvein. Reproductive structures have been examined using light, scanning, and transmission electron microscopy. This new material is compared with the other Paleocene species for which sporophytes are known and discussed in terms of evolutionary trends for the genus. The specimens suggest that most of the vegetative characteristics of modern Azolla species were established by the middle Paleocene. Key words: Azolla, Salviniaceae, megaspore, massula, ultrastructure, Paleocene.

Case series summary Lung lobe torsion is rare in cats. The aim of this multi-institution retrospective study was to describe clinical and diagnostic findings, treatments and outcomes of lung lobe torsion (LLT) in 10 cats. Dyspnoea and tachypnoea were the most common clinical signs. Pleural effusion was present in nine cats at presentation. Fluid analysis confirmed chylothorax in three cats. Nine cats underwent CT and five cats had thoracic radiographs taken. A diagnosis was made preoperatively in six cats, while in the other four cats it was made at exploratory thoracotomy. Affected lung lobes were the right cranial (n = 4/11), left cranial (n = 4/11) and right middle (n = 3/11). One cat had a concurrent torsion of two lung lobes. Lung lobectomy was successfully performed in all cases. Based on clinical, diagnostic and lung histopathology findings, three cats had idiopathic and seven cats secondary LLT. Intraoperative complications included hypotension and hypothermia in four and five cats, respectively. Postoperative complications occurred in six cats and lead to euthanasia or death in four cats, whereas complications resolved in the other two cats. Three cats were euthanased within 5 weeks of discharge. For the three cats surviving long term, including one euthanased at 252 days postoperatively, owner-described outcomes and quality of life were considered good to excellent. Relevance and novel information Secondary LLT associated with underlying thoracic pathology was associated with high complication rates and poor outcomes. Long-term outcomes of cats undergoing surgery for LLT and surviving the perioperative period were deemed good to excellent.

Four dogs had signs of pelvic limb lameness, pain, and collapse resulting from an occlusion of the distal aorta or the iliac arteries by thrombi. The diagnosis of an aortic thromboembolism was based on the absence or weakness of a femoral pulse, and the two-dimensional and Doppler ultrasonography of the abdominal aorta, iliac, and femoral arteries. Three dogs had a concurrent disease predisposing to thrombosis, including hyperadrenocorticism, protein losing nephropathy, neoplasia, and cardiac disease. Three dogs were treated with a tissue plasminogen activator (t-PA) in an attempt to lyse the thrombosis; two regained pelvic limb function. The other two dogs died shortly after the diagnosis of a thrombosis. A complete description of the history, clinical signs, laboratory analysis and imaging studies is included. Moreover, a review of the aortic thromboembolism, a diagnosis protocol and the options for its treatment are discussed.
