A serological survey for the detection of antibodies to influenza A(H1N1)pdm09 was carried out in a population of dogs and cats in Germany. A total of 1150 sera collected in 2010 and 2011 were screened using an ELISA targeting anti-nucleoprotein NP antibodies. Those initially screened positive samples were subsequently tested for antibodies to N1 neuraminidase followed by a virus neutralization test using A/Bayern/74/2009 strain. A prevalence of A(H1N1)pdm09-specific antibodies of 0.13% and 1.93% was estimated among dogs and cats, respectively. Evidence of exposure to other influenza A virus subtypes was also observed.

Melanophoromas and Iridophoromas in Reptiles

Journal of Comparative Pathology  (2011), Vol. 8- 1-11
(K.O.Heckers, H.Aupperle, V. Schmidt and M. Pees)


Chromatophoromas are tumours of pigment-producing cells of the skin and are rarely reported in reptiles. These tumours are subclassified on the basis of the type of pigment. The present study characterizes chromatophoromas arising in 26 reptiles, including six snakes, 19 lizards and a tortoise. These include the first reports of melanophoromas in a yellow anaconda (Eunectes notaeus), pigmy rattlesnake (Sistrurus spp.), southern water snake (Nerodia fasciata), veiled chameleon (Chamaeleo calyptratus) and leopard gecko (Eublepharis macularius); the first reports of benign iridophoromas in a savannah monitor (Varanus exanthematicus), veiled chameleon and bearded dragon (Pogona vitticeps); and the first description of a malignant iridophoroma in a bearded dragon. Additionally, in three bearded dragons a 'mucinous' type of melanophoroma is described for the first time. Chromatophoromas generally arose from the skin of the body and head and ranged in size from 0.2 to 2.0cm in diameter. In six cases the animals were humanely destroyed immediately after diagnosis. Three further animals were humanely destroyed following recurrence of their tumour. Six of these nine reptiles had visceral metastases. Grossly, melanophoromas (n=20) were grey or black, while iridophoromas (n=6) were white in colour. Microscopically, most of the tumours were composed of spindle cells with varying pigmentation and 0-2 mitoses per 10 high power fields. Six of the 20 melanophoromas were classified as malignant due to the presence of intravascular tumour cells, visceral metastases, high pleomorphism and/or mitotic figures. Five of the six iridophoromas were classified as benign and the one malignant tumour was defined by the presence of intravascular tumour cells and visceral metastases. Immunohistochemically, melan A and S100 were coexpressed by all of the hromatophoromas.

Cutaneous epitheliotropic T-cell lymphoma with dissemination to the liver in an eastern chipmunk (Tamias striatus)

Vet Dermatol. 2010  Apr;21(2):205-8. Epub 2009 Oct 15.
(L. Panakova, K. Heckers, M. Majzoub, RS. Mueller)


Cutaneous epitheliotropic T-cell lymphoma with liver metastasis was diagnosed in a 10-year-old eastern chipmunk (Tamias striatus). Physical findings included intracutaneous swellings, ulcerated plaques and nodules, hypotrichosis and erythema of the skin. Fine needle aspiration from the skin lesions showed a population of large lymphocytes and lymphoblasts, and was helpful in establishing the diagnosis antemortem. The post-mortem examination revealed epitheliotropic lymphoma with liver metastasis. Immunohistochemistry proved the T-cell origin both in the liver and skin tumours. Electron microscopy did not reveal any viral particles within the tumour. To the authors' knowledge, this is the first case of lymphoma described in this species.

Immunization with the transmembrane protein of a retrovirus, feline leukemia virus: Absence of antigenemia following challenge

Antiviral Research, Volume 89, Issue 1, January 2011, Pages 119-123
(S. Langhammer, J. Hübner, O. Jarrett, R. Kurth, J. Denner)


A major challenge in the development of vaccines against retroviruses is the induction of neutralizing antibodies since they prevent infection of the cells where the virus may persist. The transmembrane envelope (TM) protein contains highly conserved domains and seems to be a suitable target. To study whether vaccinating with a TM protein of a retrovirus could protect from infection in vivo, cats were immunized with the TM protein p15E of feline leukemia virus (FeLV) and subsequently challenged. For the first time we show that immunization with a retroviral TM protein prevented antigenemia. The level of neutralizing antibodies after the boost immunization correlated with the outcome of FeLV infection.


Prevalence of viral infections in captive collections of boid snakes in Germany

(M. Pees, V. Schmidt, R. E. Marschang, K. 0. Heckers, M-E. Krautwald-Junghanns) Veterinary Record April 3, 2010


Data on viral infections in apparently healthy snake collections in Germany were obtained with respect to husbandry conditions and health status. Samples from 100 boid snakes (from 14 collections) were examined microbiologically and for the presence of paramyxoviruses (PMVs) using RT-PCR. Blood was tested for the presence of antibodies against PMV, adenovirus and reovirus and for inclusion bodies indicative of inclusion body disease. Nine snakes tested positive for PMV, and inclusion bodies were detected in six snakes. Antibodies against PMV were found in one snake, and two snakes had antibodies against an adenovirus. A significant correlation was found between the origin of the snake and the presence of PMV, and between the presence of remarkable microbiological findings and husbandry conditions.

Successful treatment of Dirofilaria repens infections in dogs with melarsomine (Immiticide®, Merial) against adults and a combination of moxidectin 2.5% /imidacloprid 10% (Advocate®, Bayer) against microfilaria

(Pingen CH., Lorentz S, Magnis J., Menn B., Schaper R., Naucke T.)
WAAVP 2009, Calgary, Canada


Dirofilaria repens occurs in Europe predominately in southern and south eastern countries. Transport of dogs from such endemic regions to areas free of D. repens bears the risk of introducing this zoonotic disease to non endemic areas. In this study 507 dogs transported from a Hungarian shelter to a shelter close to Cologne from August 2006-February 2009 were tested for presence of microfilaria (mf). 60 D. repens positive dogs were enrolled in a treatment program consisting of an adulticide treatment with melarsomine (Immiticide®, Merial, 2 injections 24 h apart), followed by a microfilaricidal treatment with monthly applications of moxidectin 2.5%/imidacloprid 10% (Advocate®, Bayer) at the standard dose over a period of three month. 36 dogs completed a surveillance period of 6 month following the treatment program. Macrofilaricidal treatment in dogs was tolerated well with few adverse reactions. Microfilaricidal treatment at monthly intervals did not show adverse reactions. All 36 dogs were screened for the presence of microfilaria, all but one stayed negative. It is known from D. immitis treatment, that melarsomine at the recommended dose will clear about 50-70% of the dogs from macrofilaria and is ineffective against L4 stages and early adult stages. This treatment protocol in conjunction with a follow up treatment of 3 monthly doses of moxidectin/imidacloprid is suitable to eliminate infections with D. repens almost completely and could be an important measure to avoid introduction of this zoonotic disease from endemic to non endemic areas.

Multiple cutaneous ganglioneuromas in a dog

Veterinary Dermatology 2007 Oct;Volume 18, Issue 5; p.360-364

A 3-year-old male Labrador retriever dog was presented with multifocal small cutaneous nodules, distributed mainly over the thoracic wall, the flank and the scrotum. The dog was otherwise in good health and had no significant past medical history. Radio- and sonographic examination revealed no evidence of internal tumours, including endocrine tumours. Histological examination of two excised samples revealed round, non-ulcerated nodules in the superficial corium, characterized by two different neoplastic cell components and mild inflammation. The first tumour cell population showed histomorphological characteristics of mature ganglion cells; the second featured small, spindle-shaped tumour cells with scant cytoplasm. Both neoplastic cell components expressed vimentin, neurofilament protein, pan-neuronal neurofilament, amyloid-precursor protein and chromogranin A. In addition, the spindle-shaped tumour cells were positive for 2', 3'-cyclicnucleotide 3'-phosphodiesterase. The findings had many histological and immunohistochemical features in common with primary cutaneous ganglioneuromas in humans, enabling the canine tumours to be also classified as multiple cutaneous ganglioneuromas.

Immunohistochemical Findings in Eyes of Cats Serologically Positive for Feline Immunodeficiency Virus (FIV)

Journal of Veterinary Medicine Series B - Zentralblatt Für Veterinarmedizin Reihe B - Infectious Diseases and Veterinary Public Health, 1996, Vol 43, Iss 5, pp 305-311

(G. Loesenbeck, W. Drommer, HF. Egberink, HJ. Heider )


In this study the eyes of 15 cats in the terminal stage of FIV infection were examined. The findings were compared to those in cats, which were euthanized because of other infectious diseases or for non-infectious reasons. Thirteen FIV-infected cats showed an anterior uveitis by means of light microscopy. No accumulation of retinal lesions were found in FIV-infected cats compared to the other cats examined. Additionally, there were no indications of lesions caused by opportunistic infections. In the posterior segments of the eyes, immunohistochemical examinations proved the plasma proteins C3 and IgG to        be predominantly intravascular. The eyes of 11 serologically FIV-positive cats were available for immunohistochemical examination. In all 11 cats at least one of the plasma proteins C3 or IgG could be detected in the extravascular tissue of the anterior uvea. The extravascular presence of plasma proteins within the tissue seemed to be caused by an increased permeability of the vessels due to inflammation. Furthermore, the similar extravascular distribution pattern of IgG and complement component C3 in four cases indicated that immune complexes may play a role in the anterior uveitis of FIV-infected cats.
