A genus of deer, Rangifer, that inhabits the northern parts of Europe, Asia, and America. Caribou is the North American name; reindeer, the European. They are often domesticated and used, especially in Lapland, for drawing sleds and as a source of food. Rangifer is the only genus of the deer family in which both sexes are antlered. Most caribou inhabit arctic tundra and surrounding arboreal coniferous forests and most have seasonal shifts in migration. They are hunted extensively for their meat, skin, antlers, and other parts.

Interleukin-5 is essential for vaccine-mediated immunity but not innate resistance to a filarial parasite. (1/140)

The study of protective immune mechanisms effective against filarial nematodes has been hampered by the inability of these important human pathogens to infect laboratory mice. Recently, Litomosoides sigmodontis, a natural parasite of rats, has been developed as a valuable model for the study of filarial infection. BALB/c mice are fully susceptible to infection with L. sigmodontis third-stage larvae and develop patent infection. In contrast, mice on the C57BL background are resistant, and parasites undergo only a single molt and do not mature to adulthood. We used interleukin-5 (IL-5)-deficient mice on the C57BL/6 background to address the role of IL-5 and eosinophils in the innate resistance of C57BL/6 mice. We found no differences in parasite survival between IL-5-deficient and C57BL/6 mice. However, when these mice were used for the analysis of vaccine-mediated immunity, a critical role for IL-5 was elucidated. Mice genetically deficient in IL-5 were unable to generate a protective immune response when vaccinated with irradiated larvae, whereas C57BL/6 mice were fully protected from challenge infection. These studies help to clarify the highly controversial role of eosinophils in filarial infection.  (+info)

Targeting of Wolbachia endobacteria in Litomosoides sigmodontis: comparison of tetracyclines with chloramphenicol, macrolides and ciprofloxacin. (2/140)

Endobacteria of the genus Wolbachia in filarial nematodes are related to Rickettsiaceae and can be depleted by tetracycline antibiotics. This depletion blocks female worm development as well as early embryogenesis, in contrast to the currently used microfilaricidal ivermectin which blocks only the last stage of embryogenesis. Since targeting Wolbachia is becoming an area of research for the treatment of human filariases, it was investigated if antibiotics other than tetracyclines are able to deplete Wolbachia from filariae. BALB/c mice infected with the rodent filaria Litomosoides sigmodontis were treated with erythromycin, chloramphenicol or ciprofloxacin. All drugs were well resorbed and resulted in serum levels clearly above breakpoint levels for bacteria susceptible to the respective antibiotic. However, contrary to tetracycline, none of these antibiotics depleted Wolbachia or altered worm development and fertility, as evidenced by immunohistology, immunoelectron microscopy and semiquantitative PCR.  (+info)

Phosphocholine-containing, zwitterionic glycosphingolipids of adult Onchocerca volvulus as highly conserved antigenic structures of parasitic nematodes. (3/140)

Human Onchocerca volvulus infection sera were found to recognize zwitterionic glycolipids of O. volvulus and to cross-react with those of other parasitic nematodes (Ascaris suum, Setaria digitata and Litomosoides sigmodontis). By the use of an epitope-specific monoclonal antibody, zwitterionic glycolipids of all these nematode species were observed to contain the antigenic determinant phosphocholine. A hyperimmune serum specific for arthro-series glycolipid structures reacted with the various neutral glycolipids of all these nematodes, which demonstrated that their oligosaccharide moieties belonged to the arthro-series of protostomial glycolipids. These results indicated that arthro-series glycosphingolipids carrying, in part, phosphocholine substituents, represent highly conserved, antigenic glycolipid markers of parasitic nematodes. Three glycolipid components of the O. volvulus zwitterionic fraction were structurally characterized by matrix-assisted laser-desorption/ionization time-of-flight MS, methylation analysis and exoglycosidase treatment. Their chemical structures were elucidated to be phosphocholine-6GlcNAc(beta1-3)Man(beta1-4)Glc(1-1)ceramide, GalNAc(beta1-4)[phosphocholine-6]GlcNAc(beta1-3)Man(beta1-4)Glc(1-1) ceramide and Gal(alpha1-3)GalNAc(beta1-4)[phosphocholine-6]GlcNAc(beta1-3)Man(beta 1-4)Glc(1-1)ceramide for the zwitterionic ceramide tri-, tetra- and penta-hexosides respectively. The ceramide composition was found to be dominated by 2-hydroxylated docosanoic (C(22h:0)), tricosanoic (C(23h:0)) and tetracosanoic (C(24h:0)) acids, and C(17) sphingosine (C(d17:1)) (where (h) is hydroxylated and (d) is dihydroxylated).  (+info)

Drastic reduction of a filarial infection in eosinophilic interleukin-5 transgenic mice. (4/140)

In order to establish the role of eosinophils in destroying parasites, transgenic mice have been used in experimental helminthiases but not in filariasis. Litomosoides sigmodontis offers a good opportunity for this study because it is the only filarial species that completes its life cycle in mice. Its development was compared in transgenic CBA/Ca mice overexpressing interleukin-5 (IL-5) and in wild-type mice following subcutaneous inoculation of 40 infective larvae. An acceleration of larval growth was observed in the IL-5 transgenic mice. However, the recovery rate of adult worms was considerably reduced in these mice, as evidenced 2 months postinoculation (p.i.). The reduction occurs between days 10 and 30 p.i. in the coelomic cavities. As early as day 10, spherical aggregates of eosinophils and macrophages are seen attached on live developing larvae (always similarly localized on the worm) in both wild-type and transgenic mice. However, on day 60 p.i., granulomas were found in the transgenic mice only, probably because of the higher density of eosinophils. Furthermore, on day 30 p.i., young filariae are seen trapped in granulomas, some of them surrounded by Splendore-Hoeppli deposits, which illustrates the release of the major basic protein by eosinophils. The high protection rate obtained (65%) is similar to that observed previously in BALB/c mice following vaccination with irradiated larvae. Both protocols have a common factor, the high production of IL-5 and eosinophilia. However, protection occurs later in primary infected transgenic mice because specific antibodies are not yet present at the time of challenge.  (+info)

Epidemiological studies on onchocerciasis by means of a new field technique. (5/140)

A new membrane filter concentration technique for the detection and quantification of Onchocerca volvulus microfilariae in skin snips was compared for sensitivity and efficiency with a widely used "standard" technique. A field study was carried out in five villages in an onchocerciasis focus north-east of the town of Sokode, Mo river valley, Togo. Use of the new technique resulted in a substantial rise in the observed prevalence and density of microfilariae.  (+info)

Analysis of genes expressed at the infective larval stage validates utility of Litomosoides sigmodontis as a murine model for filarial vaccine development. (6/140)

We used an expressed sequence tag approach to analyze genes expressed by the infective larvae of the rodent filarial parasite Litomosoides sigmodontis. One hundred fifty two new genes were identified, including several proposed as vaccine candidates in studies with human filarial parasites. Our findings have important implications for the use of L. sigmodontis as a model for filarial infection.  (+info)

Presence of phosphorylcholine on a filarial nematode protein influences immunoglobulin G subclass response to the molecule by an interleukin-10-dependent mechanism. (7/140)

The filarial nematode product ES-62 contains phosphorylcholine (PC) covalently attached to N-linked glycans. ES-62 induced high levels of immunoglobulin G1 (IgG1) antibodies, but no IgG2a, to non-PC epitopes of the molecule following subcutaneous injection into BALB/c mice. Conversely, mice given ES-62 lacking PC demonstrated significant production of both IgG subclasses. Thus, PC appears to block production of IgG2a antibodies to other epitopes on the parasite molecule. A role for interleukin-10 (IL-10) in this effect was shown by the ability of IL-10(-/-) mice to make an IgG2a antibody response to non-PC epitopes of ES-62.  (+info)

Interleukin-4 is essential for the control of microfilariae in murine infection with the filaria Litomosoides sigmodontis. (8/140)

Litomosoides sigmodontis is the only filaria which develops from infective larvae into microfilaria-producing adults in immunocompetent laboratory mice. In this study we report that interleukin-4 knockout (IL-4 KO) mice have an up to 100-fold-higher and a significantly prolonged microfilaremia compared to wild-type BALB/c mice, as well as 20 times more microfilariae in the thoracic cavity, the site of infection. While worm development and adult worm persistence were equivalent in IL-4 KO and wild-type mice, the fertility and length of adult female worms in IL-4 KO mice was clearly enhanced. The high susceptibility to microfilariae in IL-4 KO mice required the presence of adult worms in a full infection cycle since microfilariae loads did not differ much between IL-4 KO and wild-type mice when purified microfilariae were injected into mice. In addition, we found that eosinophilia was diminished and immunoglobulin E (IgE) was absent in IL-4 KO mice. IgE, however, does not seem to be the essential factor for microfilarial containment since microfilaremia was not elevated in B-cell KO mice. In conclusion, IL-4 is shown for the first time to be essential for the control of microfilarial loads but not of adult worm loads in a fully permissive murine filarial infection. IL-4 dependent effector pathways seem to operate on adult worms rather than directly on microfilariae.  (+info)

Ym1 and Fizz1 are secreted proteins that have been identified in a variety of Th2-mediated inflammatory settings. We originally found Ym1 and Fizz1 as highly expressed macrophage genes in a Brugia malayi infection model. Here, we show that their expression is a generalized feature of nematode infection and that they are induced at the site of infection with both the tissue nematode Litomosoides sigmodontis and the gastrointestinal nematode Nippostrongylus brasiliensis. At the sites of infection with N. brasiliensis, we also observed induction of other chitinase and Fizz family members (ChaFFs): acidic mammalian chitinase (AMCase) and Fizz2. The high expression of both Ym1 and AMCase in the lungs of infected mice suggests that abundant chitinase production is an important feature of Th2 immune responses in the lung. In addition to expression of ChaFFs in the tissues, Ym1 and Fizz1 expression was observed in the lymph nodes. Expression both in vitro and in vivo was restricted to antigen-presenting ...

Within 7 days post-infection this resulted in an increased percentage of CD4+ T cells at the infection site expressing Foxp3. Antibody-mediated depletion of CD25+ cells prior to infection to remove pre-existing natural CD4+CD25+Foxp3+ Treg cells, while not affecting initial larval establishment, significantly reduced the number of ...

In countries where parasitic infections are endemic, autoimmune disease is relatively rare, leading to the hypothesis that parasite-derived immunomodulators may protect against its development. Consistent with this, we have previously demonstrated that ES-62, a 62 kDa phosphorylcholine (PC)-containing glycoprotein that is secreted by filarial nematodes, can exert anti-inflammatory action in the murine collagen-induced arthritis (CIA) model and human rheumatoid arthritis-derived synovial tissue cultures. As a first step to developing ES-62-based drugs, the aim of this study was to determine whether the PC-moiety of ES-62 was responsible for its anti-inflammatory actions. We compared the anti-inflammatory activity of a PC-free form of recombinant ES-62 (rES-62) and a synthetic PC-ovalbumin conjugate (OVA-PC) with that of native ES-62 in the CIA model and synovial tissues from patients with rheumatoid arthritis. Results: The anti-inflammatory actions of ES-62 in CIA appear to be dependent on the PC ...

Filarial nematodes are capable of causing significant disease with long-term ramifications in humans and animals. Intermediate hosts, or vectors, are involved in all instances. Interestingly, although they infect different locations in their respective hosts, the filarial worm species are remarkably similar in many ways.. In humans, the most prevalent filarial infections can result in blindness (Onchocerca volvulus) or lymphedema (Brugia malayi, B. timori and Wuchereria bancrofti).. The intermediate hosts of O. volvulus are blackflies, which transfer infective larvae to a susceptible person approximately 2 to 3 weeks after becoming infected by microfilariae in a blood meal from an infected host. The infective larvae migrate into the subcutaneous tissue in the competent host and form nodules under the surface of the skin while maturing into adult worms. Adult female O. volvulus produce 750 to 1600 microfilariae daily [8, 9]. When adult worms or microfilariae die, the resulting inflammatory ...
Parasitic filarial nematodes are often tolerated in their human hosts for decades, with little evidence of pathology, due to parasite-induced immune modulation. The consensus of opinion, to date, is that such parasites achieve prolonged survival as a result of their active modulation of the hosts immune system by secreted immunomodulatory molecules. Consistent with this, the excretory-secretory protein of Acanthocheilonema vitae, ES-62, has been shown to exhibit immunomodulatory activities that are broadly Th2/anti-inflammatory in nature. Dendritic cells are specialised antigen (Ag)-presenting cells critical for initiating and regulating immune responses. They stimulate T cells and produce cytokines that have important immuneregulatory functions. To date, more than 6 different DC subtypes have been identified that arise from at least two different cell lineages. These subtypes are not only phenotypically distinct but they are also thought to perform different functions and be restricted to ...

Wolbachia, a gram negative bacterial endosymbiont belonging to the Rickettiales, has been described in the body of various species of filarial nematodes (Sironi et al. 1995; Bandi et al., 1998, Casiraghi et al., 2001). These bacteria are present in the lateral chords of both males and females, in the reproductive apparatus of females and also in the larvae present in the vector (Bandi et al., 2001). Wolbachia has also been shown to be transovarially transmitted from female worms to the offspring. In addition, a 100% prevalence of infection in the filarial species positive for Wolbachia is suggestive of an obligatory symbiosis between bacteria and its host (Bandi et al., 2001). Furthermore, drugs like tetracycline, known to be effective against Rickettsia-like bacteria, have been shown to cause detrimental effects on filarial nematodes which harbour Wolbachia, and no effects on filarial nematodes which do not harbour these bacteria (Bandi et al., 1999, Hoerauf et al., 1999; Langworthy et al., ...

It was recently demonstrated that the lone star tick Amblyomma americanum could harbor filarial nematodes within the genus Acanthocheilonema. In this study, Ixodes scapularis (deer) ticks collected from Southern Connecticut were evaluated for their potential to harbor filarial nematodes. Non-engorged nymphal and adult stage Ixodes scapularis ticks were collected in Southern Connecticut using the standard drag method. In situ hybridization with filarial nematode specific sequences demonstrated the presence of filarial nematodes in Ixodes ticks. Filarial nematode specific DNA sequences were amplified and confirmed by direct sequencing in Ixodes nymphal and adult ticks using either general filarial nematode or Onchocercidae family specific PCR primers. Phylogenetic analysis of the 12S rDNA gene sequence indicated that the filarial nematode infecting Ixodes scapularis ticks is most closely related to the species found in Amblyoma americanum ticks and belongs to the genus of Acanthocheilonema.

Background & objectives: Dirofilaria immitis is a filarial nematode that causes heartworm disease in domestic as well as wild canines and felines; and cutaneous or pulmonary infections in humans. The purpose of the study was to estimate the prevalence of D. immitis in domestic dogs in Tabasco, Mexico and to assay mosquitoes temporally and spatially associated with dogs for evidence of infection. Methods: Blood was collected from 1050 dogs in 1039 houses during a random household survey performed in 2016 and 2017. Genomic DNA was extracted and assayed by polymerase chain reaction (PCR) using pan-filarial primers and various species-specific primers. Dog owners were interviewed using a structured questionnaire designed to collect information on factors that may impact the occurrence of filarial infection. The association between canine dirofilariasis prevalence and factors likely to impact infection was determined by univariate logistic regression analysis, followed by multivariate binomial ...

Recent studies have revealed expansion by an array of Filarioid nematodes into the northern boreal region of Finland. The vector-borne nematode, Setaria tundra, caused a serious disease outbreak in the Finnish reindeer population in 2003-05. The main aim of this study was to understand the outbreak dynamics and the rapid expansion of S. tundra in the sub arctic. We describe the vectors of S. tundra, and its development in vectors, for the first time. Finally we discuss the results in the context of the host-parasite ecology of S. tundra in Finland Development of S. tundra to the infective stage occurs in mosquitoes, (genera Aedes and Anopheles). We consider Aedes spp. the most important vectors. The prevalence of S. tundra naturally infected mosquitoes from Finland varied from 0.5 to 2.5%. The rate of development in mosquitoes was temperature-dependent. Infective larvae were present approximately 14 days after a blood meal in mosquitoes maintained at room temperature (mean 21 C), but did not develop in
Filarial nematodes harbour intracellular endosymbiotic bacteria, which have been assigned to the genus Wolbachia. These bacteria appear to play an important role in the pathogenesis of filarial diseases through their lipopolysaccharides. In view of the presence of Wolbachia endosymbionts in the body of filarial nematodes, one might also expect that proteins from these bacteria play an antigenic role in humans and animals affected by filariases. To test this hypothesis, we produced in recombinant form the surface protein WSP and a portion of the cell-cycle protein FTSZ from the Wolbachia of Dirofilaria immitis. Western immunoblot assays were then performed using cat sera to test the immunogenicity of these proteins. Sera were collected from owners cats, which were either sero-negative or sero-positive for D.immitis and from cats before and after experimental infection with D.immitis.

Eggs are passed through the feces of an infected definitive host, usually a mammalian herbivore including rabbits, sheep, cattle, and rodents.[6] Under certain environmental conditions, which include optimal temperature and humidity, larvae hatch from eggs after several days. Hatched rhabditiform larvae grow on vegetation or within soil. After 5 to 10 days, two molts (L1 & L2) have occurred and the parasite becomes a filariform (L3) larvae that is infectious. Infection in mammals occurs upon ingestion of infective filariform (L3) larvae. The larvae reaches the small intestine to reside and mature into adult worms within their definitive hosts. Infections in humans may occur as incidental infections.[7] Trichostrongylus consists of multiple species that relate to each of its host, when it comes to parasitic survival and infection. For example, Trichostrongylus affinis primarily infects cottontail rats, Trichostrongylus sigmodontis affects hispid cotton rat, and marsh rice rat, and ...
Microarray technology permits high-throughput comparisons of gene expression in different parasite stages or sexes and has been used widely. We report the first use of this technology for analysis of gene expression in filarial male and female worms. The slide array (comprised of 65-mer oligos representing 3569 EST clusters) was spotted with sequences selected from the extensive Brugia malayi EST database (). Arrays were hybridized with Cy dye labeled male and female cDNA. The experimental design included both biological and technical (dye-flip) replicates. The data were normalized for background and probe intensity, and the relative abundance of hybridized cDNA for each spot was determined. Genes showing two-fold or greater differences with P,0.05 were considered gender-regulated candidates. One thousand one hundred and seventy of 2443 clusters (48%) with signals above threshold in at least one sex were considered as gender-regulated gene candidates. This included 520 and 650 clusters ...
Heartworm: Dirofilaria immitis. A common parasite of dogs in many parts of the world that occurs in other animals, including cats, but rarely infects humans. The adult worms, which are up to 10 inches (25 cm) in length, typically live in the dogs pulmonary artery and right side of the heart. Inflammation and thickening of the heart may result in heart failure, respiratory insufficiency, chronic cough, and vomiting. The disease can be fatal. The female worms produce microfilariae that are found in the dogs blood. The microfilariae are ingested by a mosquito when it feeds on a dog, the microfilariae mature into infective juveniles in the vector, and the infection is transmitted to a new host when the mosquito feeds. Many species of mosquitoes serve as vectors for the heartworm. ProHeart 6, a twice-a-year time-released heartworm medication, was recalled in 2004 at the request of the FDA after thousands of dogs suffered adverse reactions, including liver and bleeding abnormalities followed in some ...

Many patients infected with filarial worms have no symptoms, but those who develop disfiguring lymphatic filariasis -- more commonly known as elephantiasis -- often struggle with discrimination and rejection. Now, researchers have quantified that burden, reporting in PLOS Neglected Tropical Diseases that lymphatic filariasis patients in Nigeria have about four times the rate of depression as other adults there.

856 million people in 52 countries worldwide are at risk of this disease commonly known as elephantiasis. Infection occurs when filarial parasites are transmitted to humans through mosquitoes, usually in childhood. A painful and profoundly disfiguring NTD, it can leave patients physically disabled and contribute to mental, social and financial losses, stigma and poverty.. ...

Dirofilaria immitis, the canine heartworm, is one of the most important filaroids parasite in carnivores. The dog and its close relative are natural hosts, but infection also occurs in cat, wild carnivores and man. Adult heartworms normally are found in the pulmonary arteries. Female kind of Dirofilaria immitis frees its microfilaria in blood stream and microfilaria are distributed by circulatory system throughout the body. Several species of mosquitoes are as intermediated hosts. This study was done within 8 months in six areas susceptible to infection in the vicinity of Tabriz. 60 dogs (between 1- 4 years olds) were caught by strychnine poisoned meat and were necropsied. In examination of hearts of dogs, Dirofilaria immitis is found in 19 cases (31.6%) and all worms were located in right ventricle and in right arteries. There were no worms in plumnary arteries. In positive cases at least 1 worm and at most 18 worms were observed. The intensity of infection in old dogs was much greater than ...
Author Summary Brugia malayi is a nematode which causes lymphatic filariasis in South and South-East Asia. Most infected people harbour many millions of the microfilarial stage of the parasite in their blood stream and yet they show few visible symptoms of disease. Vascular endothelial cells (EC) line the blood vessels and are therefore in direct contact with microfilariae. Since vascular EC are potent immune cells functioning in the production of both immune mediators and regulating the migration of immune cells from the blood into the tissue, we have established an in vitro model in which to test the effect of live Mf upon vascular EC function. Strikingly, we observed that Mf exposure caused reduced transendothelial migration of neutrophils and monocytes, but not lymphocytes. However, microfilariae stimulated EC production of few pro-inflammatory mediators. Additionally, while filarial infection is known to stimulate mediators that increase blood vessel formation in vivo, live microfilariae promoted
Abstract A 4.5-mm filarial worm was removed from the anterior chamber of the left eye of a 56-year-old man who had lost the sight in the right eye due to trauma some years earlier. The worm was removed intact through an upper scleral incision with a corneal based flap. Within 2 months vision was normal. The worm was identified as a sexually mature male of an undescribed species of Loaina Eberhard and Orihel 1984, a genus related to Loa and Dirofilaria.
Heartworm treatment is a very important part of dog health care. One common parasite is the dirofilaria immitis, a roundworm parasite that travels from host to host through the blood, transferred by mosquitoes biting multiple victims. The worm itself is a filament-like, slim worm that completes its life cycle in mammals. Check below for more info and related dog treatments and care.

Wolbachia is the most widespread bacterial endosymbiont. It is found in about 40% of all terrestrial arthropods, and in filarial nematodes. Among Wolbachia strains, multiple genetically distinct lineages can be differentiated. These lineages differ in their host spectrum, their prevalence and in the phenotypes they can induce in their hosts. I am interested in reconstructing the evolutionary history of these Wolbachia lineages in order to understand which evolutionary transitions have occurred at what time in the history of Wolbachia ...
p53 is a key regulator of the DNA damage-induced checkpoint in mammals (reviewed in Sancar et al., 2004). cep-1, the C. elegans homolog of p53, is required for DNA damage-induced apoptosis in the C. elegans germ line, but not for programmed cell death occurring during worm development nor physiological (radiation-independent) germ cell death (Schumacher et al., 2001; Derry et al., 2001). Despite the differences in the three-dimensional structure of the DNA binding domain between CEP-1 and human p53 (Huyen et al., 2004) its role in the DNA damage checkpoint appears to be conserved. Furthermore, CEP-1 can induce apoptosis in mammalian cells and this induction can be inhibited by iASPP, an evolutionarily conserved inhibitor of p53 (Bergamaschi et al., 2003). Several genes have been identified that either regulate cep-1 activity or are regulated by cep-1. The C.elegans iASPP ortholog, ape-1 (apoptotic enhancer) is a conserved inhibitor of cep-1. ape-1(RNAi) results in an increase in cep-1-mediated ...
Following the suggestion of Sidney Brenner to document all the cells inCaenorhabditis elegans, Bob Horvitz and John Sulston in 1977 published a map of the worms development, noting also that 111 cells were born only to die shortly thereafter. By 1990 Horvitzs group had identified a small number of genes that controlled the deaths of these cells, when they electrified the community by announcing that the primary killer gene was not only a protease but a known protease.. This discovery burst open the entire subject of apoptosis, leading quickly to recognition of the caspase family of proteases and generating the fervent activity that we now see in research and biotechnical and pharmaceutical efforts to directly or indirectly control the activity of caspases and thereby apoptosis. For this and many subsequent discoveries, Horvitz, Sulston, and Brenner were awarded the 2002 Nobel Prize in Physiology or Medicine. ...

Samurott used to be a powerful, majestic beast. He could use his sword to slice foes in half. He could swim entire lakes. One glare from him used to intimidate opponents. He won so many tournaments. His master was so incredibly proud of him. He was a Level 100 Samurott. An unstoppable, unbeatable, unconquerable champion!. At least, he used to be all of that.. Not anymore.. Heartworm. Dirofilaria immitis, if you wanted to use the scientific term. That one diagnosis changed Samurotts life faster and more powerfully than anything else could have. That one word… disease… abomination… had caused his life to quickly spiral downward in a sea of medicines, tests, constant doctor appointments, and other diseases that branched off of heartworm. It was too much for Samurott to take. It had disintegrated his health and battle spirit into virtually nothing.. Now, it wouldnt surprise Samurott if his master was ashamed of him now. And why wouldnt he be? His master no longer had a powerful, majestic ...
