Abstract
The health monitoring of laboratory rodents is essential for ensuring animal health and standardization in biomedical research. Progress in housing, gnotobiotic derivation, and hygienic monitoring programs led to enormous improvement of the microbiological quality of laboratory animals. While traditional health monitoring and pathogen detection methods still serve as powerful tools for the diagnostics of common animal diseases, molecular methods develop rapidly and not only improve test sensitivities but also allow high throughput analyses of various sample types. Concurrently, to the progress in pathogen detection and elimination, the research community becomes increasingly aware of the striking influence of microbiome compositions in laboratory animals, affecting disease phenotypes and the scientific value of research data. As repeated re-derivation cycles and strict barrier husbandry of laboratory rodents resulted in a limited diversity of the animals' gut microbiome, future monitoring approaches will have to reform-aiming at enhancing the validity of animal experiments. This review will recapitulate common health monitoring concepts and, moreover, outline strategies and measures on coping with microbiome variation in order to increase reproducibility, replicability and generalizability.

Abstract
Bacteria are relevant in rodent quality assurance programmes if (a) the animals are at risk and (b) presence in the animals makes a difference for animal research or welfare, for example because the agent regulates clinical disease progression or impacts its host in other ways. Furthermore, zoonoses are relevant. Some bacterial species internationally recommended for the health monitoring of rats and mice, that is, Citrobacter rodentium, Corynebacterium kutscheri, Salmonella spp. and Streptococcus pneumonia, are no longer found in either laboratory or pet shop rats or mice, while there is still a real risk of impact on animal research and welfare from Filobacterium rodentium, Clostridium piliforme, Mycoplasma spp., Helicobacter spp. and Rodentibacter spp., while Streptobacillus moniliformis may be considered a serious zoonotic agent in spite of a very low risk. Modern molecular techniques have revealed that there may, depending on the research type, be equally good reasons for knowing the colony status of some commensal bacteria that are essential for the induction of specific rodent models, such as Alistipes spp., Akkermansia muciniphila, Bifidobacterium spp., Bacteroides fragilis, Bacteroides vulgatus, Faecalibacterium prausnitzii, Prevotella copri and segmented filamentous bacteria. In future, research groups should therefore consider the presence or absence of a short list of defined bacterial species relevant for their models. This list can be tested by cost-effective sequencing or even a simple multiple polymerase chain reaction approach, which is likely to be cost-neutral compared to more traditional screening methods.

Abstract
There is currently increasing concern about the relation between microbial infections and cancer. More and more studies support the view that there is an association, above all, when the causal agents are bacteria or viruses. This review adds to this, summarizing evidence that the opportunistic fungus Candida albicans increases the risk of carcinogenesis and metastasis. Until recent years, Candida spp. had fundamentally been linked to cancerous processes as it is an opportunist pathogen that takes advantage of the immunosuppressed state of patients particularly due to chemotherapy. In contrast, the most recent findings demonstrate that C. albicans is capable of promoting cancer by several mechanisms, as described in the review: production of carcinogenic byproducts, triggering of inflammation, induction of Th17 response and molecular mimicry. We underline the need not only to control this type of infection during cancer treatment, especially given the major role of this yeast species in nosocomial infections, but also to find new therapeutic approaches to avoid the pro-tumor effect of this fungal species.

Abstract
Mycoplasma pulmonis is one of the most prevalent bacterial pathogens
that infects laboratory mice and rats. To develop an M. pulmonis-specific
antigen for serological diagnosis, we cloned the cDNA of P46-like lipoprotein (P46L), an
M. pulmonis putative periplasmic protein. P46L is a homolog of P46, an
M. hyopneumoniae antigen. We produced recombinant P46L fused to
glutathione S-transferase (GST) in Escherichia coli. Immunoblot analysis
revealed that sera from Mycoplasma-infected mice and rats contained
anti-P46L antibodies. We developed an ELISA using the recombinant P46L-GST protein as an
antigen. Thirteen of the 14 samples from rats naturally infected with M.
pulmonis were determined to be positive according to the commercial ELISA
(MONILISA Myco) and positive by our ELISA. Furthermore, 18/19 samples from mice
experimentally infected with M. pulmonis were positive using our P46L-GST
ELISA. In contrast, only 8/19 samples from infected mice were positive by the commercial
ELISA. Our results indicate that P46L-GST was an appropriate antigen for developing a
serological test to determine M. pulmonis infection in laboratory mice
and rats.

Molecular fractionation and characterization of a Candida albicans fraction that increases tumor cell adhesion to hepatic endothelium. Appl Microbiol Biotechnol 2011; 92:133-45.

Abstract
Systemic candidiasis remains a major complication among patients suffering from hematological malignancies and favors the development of hepatic metastasis. To contribute to the understanding of the underlying mechanisms, the aim of this study was to identify molecules that may increase tumor cell adhesion to hepatic endothelial cells. To this end, a well-established in vitro model was used to determine the enhancement of tumor cell adhesion induced by Candida albicans and its fractions. Different fractions were obtained according to their molecular weight (M(r)) (five) or to their isoelectric point (pI) (four), using preparative electrophoresis and preparative isoelectric focusing, respectively, followed by affinity chromatography. The fraction that most enhanced melanoma cell adhesion to endothelium had an M(r) range from 45 to 66 kDa. It was characterized using two-dimensional electrophoresis, and 14 proteins were identified by peptide mass fingerprinting: Dor14p, Fba1p, Pdi1p, Pgk1p, Idh2p, Mpg1p, Sfa1p, Ape3p, Ilv5p, Tuf1p, Act1p, Eno1p, Qcr2p, and Adh1p. Of these, several are related to the immunogenic response, and the latter seven belonged to the most reactive fraction according to their pI range, from 5 to 5.6. These findings could represent a step forward in the search for new targets, to suppress the pro-metastatic effect of C. albicans.

Abstract
Many steps of the metastatic cascade can be reproduced in simple in vitro assays such as tumour cell interactions with matrix proteins, proteolysis, chemotaxis, haptotaxis, and invasion into matrices or explanted tissues. Nevertheless, there are no fully adequate substitutes for the complexity of the in vivo process. Here, we describe two "experimental" metastasis assays to yield lung or liver colonies (mimicking established micrometastatic disease), and two spontaneous metastasis assays for breast and prostate carcinomas. Examples include either murine tumour cell lines in syngeneic immunocompetent mice or human tumour xenografts in immunodeprived mice.

Abstract
Animal experiments remain essential to understand the fundamental mechanisms underpinning malignancy and to discover improved methods to prevent, diagnose and treat cancer. Excellent standards of animal care are fully consistent with the conduct of high quality cancer research. Here we provide updated guidelines on the welfare and use of animals in cancer research. All experiments should incorporate the 3Rs: replacement, reduction and refinement. Focusing on animal welfare, we present recommendations on all aspects of cancer research, including: study design, statistics and pilot studies; choice of tumour models (e.g., genetically engineered, orthotopic and metastatic); therapy (including drugs and radiation); imaging (covering techniques, anaesthesia and restraint); humane endpoints (including tumour burden and site); and publication of best practice.

Abstract
Candida albicans infections are very frequent in cancer patients, whose immune system is often compromised, but whether this fungal pathogen affects cancer progression is unknown. C. albicans infection involves endogenous production of inflammatory cytokines such as tumour necrosis factor alpha (TNF-alpha) and interleukin-18 (IL-18). Increased levels of these cytokines have already been correlated with metastasis of most common cancer types. In this study, a well-established model of IL-18-dependent hepatic melanoma metastasis was used to study whether C. albicans can alter the ability of murine B16 melanoma (B16M) cells to colonize the liver. First, we determined the ability of intrasplenically (IS) injected B16M cells to metastasize into the liver of mice challenged with 5 x 10(4) C. albicans cells by three different routes (intravenous, IV; intrasplenic, IS; or intraperitoneal, IP) 12 h prior to injection of B16M cells. We demonstrated that C. albicans significantly increased metastasis of B16M cells with all three fungal injection routes. Pro-metastatic effects occurred when hepatic colonization with B16M cells place after the peak of TNF-alpha and IL-18 levels had been reached in the hepatic blood of fungal challenged mice. In a second set of experiments, mice were fungal challenged 4 days after injection of B16M cells. In these mice, C. albicans also potentiated the growth of established micro-metastases. Significantly, the fungal challenge had pro-metastatic effects without the C. albicans being able to reach the liver, suggesting that soluble factors can promote metastasis in remote sites. Mouse treatment with antifungal ketoconazol abrogated hepatic TNF-alpha stimulation by C. albicans and prevented the enhancement of hepatic metastasis in fungal challenged-mice. Therefore, the pro-inflammatory microenvironment generated by the host's systemic response to C. albicans stimulates circulating cancer cells to metastasize in the liver.

Abstract
To test whether transgenic Epstein-Barr virus nuclear antigen 1 (EBNA1) expression in C57BL/6 mouse lymphocytes causes lymphoma, EBNA1 expressed in three FVB lineages at two or three times the level of latent infection was crossed up to six successive times into C57BL/6J mice. After five or six crosses, 14/36, (38%) EBNA1 transgenic mice, 11/31 (36%) littermate EBNA1-negative controls, and 9/25 (36%) inbred C57BL/6J mice housed in the same facility had lymphoma. These data indicate that EBNA1 does not significantly increase lymphoma prevalence in C57BL/6J mice.
