Macrophages are a diverse population of specialized phagocytic cells that are essential for host defense, homeostasis and wound repair. They are derived from bone marrow precursors and circulating blood monocytes, which differentiate into resident macrophages or DCs upon tissue entry [ ]. Further extension of this work demonstrated that depletion of macrophages, by treatment with clodronate-containing liposomes, reduced resistance to C.

In addition, the authors showed that IL was an important factor for immunity to C. The role of macrophages in human and ruminant models of cryptosporidiosis is currently unknown. Th1 biased immune responses are important for protection against intracellular pathogens and are involved during Cryptosporidium infection.

PBMCs from neonatal calves experimentally infected with C. Treatment of immunocompetent or immunodeficient mice with exogenous IL prior to infection with C. Furthermore, IL-4 deficient mice also exhibited prolonged excretion of C. Thus, production of the Th2 cytokine IL-4 in response to murine C. In mice immunosuppressed by dexamethasone and then infected with C. There is little known about the possible role of Th17 immune response during the bovine immune response to C. Furthermore, following infection of 1 day old lambs with C.

The relevance of B cells and immunoglobulins during Cryptosporidium infection remains controversial. Mice depleted of B cells and therefore unable to produce appropriate levels of protective antibody were able to control C. Using gene-targeted B cell deficient mice, it has also been shown that B cells were not required for resistance to initial C.

Data from these studies suggest that B cells and antibody-mediated immune responses may not be necessary for protection against murine C. Whether the same is true for protection against Cryptosporidium infection in natural host species remains to be determined. Generally, mice infected with C. Additionally, bovine-specific examples such as the significantly increased frequency of nonconventional T cells, ultralong complementarity-determining region 3 CDR3 domain antibodies and uniquely expanded NK receptor repertoires [ , , ] illustrate the many fundamental differences between the murine and bovine immune systems.

The impact that these factors may play during Cryptosporidium infection cannot be captured using mouse models. Improved in vitro models would also ideally be developed in order to enable the study of the interaction between C. To date, epithelial cell lines particularly the HCT-8 cell line have been utilised to decipher the interaction between the parasite and human intestinal epithelial cells.

Whilst these studies are valuable, epithelial cell lines are not fully representative of the complex structure and cellular diversity of the intestinal epithelium, which consists of many cell types including epithelial cells, goblet cells, stem cells, Paneth cells and enteroendocrine cells.

These are three dimensional structures, differentiated in vitro from intestinal stem cells, which recapitulate the structure of the intestinal epithelium in vivo and contain all of the cell types associated with the intestine. Organoids would be excellent tools to study the early interactions of Cryptosporidium with the gut epithelium, as pathogens can be introduced into the lumen of the intestinal organoids in vitro enabling their relationship with the host to be deciphered in a physiologically relevant context.

Zhang et al. The authors illustrated that the presence of C. Therefore, similar in vitro systems would be advantageous to understand the nature of the host—pathogen interaction during C. Despite being discovered over years ago Cryptosporidium remains one of the most difficult pathogens to control on farms and in the environment.

To date, progress in the development of effective treatments for humans or animals has been slow. This may be due, in part, to the lack of understanding of the cellular and molecular interactions that occur in the gut mucosa during the early stage interactions between host and parasite. The majority of studies that have been carried out have focussed on mice, an asymptomatic model. Therefore, a more in-depth understanding of the pathogenesis of Cryptosporidium infection in clinically relevant hosts is urgently required.

Data derived from these studies is necessary to help identify the factors that influence disease resistance and recovery, and to aid the development of effective control strategies to help control this important disease.

Mabbott 2 , Liam J. Abstract Gastrointestinal disease caused by the apicomplexan parasite Cryptosporidium parvum is one of the most important diseases of young ruminant livestock, particularly neonatal calves. Introduction Cryptosporidium parvum was first described in by Edward Ernst Tyzzer in the small intestine of mice [ 1 ].

Figure 1. Full size image. Figure 2. Figure 3. Bovine cryptosporidiosis Four species of Cryptosporidium are commonly found in cattle: C. Prevalence Bovine cryptosporidiosis is widespread and has been reported as a major cause of calf enteritis [ 5 , 6 , 7 ] in many countries throughout the world [ 26 , 27 , 28 , 29 ]. Economic and production impact The precise economic losses associated with bovine cryptosporidiosis have not thus far been examined in detail but include the cost of treatment and management of enteritis, reduced feed conversion and production efficiency and losses due to animal death.

Zoonotic implications Most human cases of cryptosporidiosis are caused by either the zoonotic species C. Environmental impacts The rapid amplification of C. Current control measures for bovine cryptosporidiosis Cryptosporidiosis is a difficult disease to control due to environmentally stable oocysts, low infective dose and high levels of excreted sporulated oocysts and infection may be transmitted to a group of susceptible hosts very quickly.

Farm management practices As the oocysts of C. Therapeutics At present, few products are licensed in the UK for the treatment or prevention of cryptosporidiosis in livestock or humans. Livestock The only licensed treatment for cryptosporidiosis in calves is halofuginone lactate, the mechanism of action of this drug is unknown but it is thought to affect the merozoite and sporozoite stage of the parasite [ 71 ].

Vaccines Currently, there are no vaccines available to prevent cryptosporidiosis in either farm livestock or humans. Immunology of cryptosporidiosis The development of future control methods against Cryptosporidium is likely to focus on vaccines and other immunotherapies. Figure 4. Concluding remarks Despite being discovered over years ago Cryptosporidium remains one of the most difficult pathogens to control on farms and in the environment.

References 1. Arch fur Protistenkunde — Google Scholar 2. Vet Pathol — Article Google Scholar 4. It is caused by a parasite called cryptosporidium and is usually seen in young calves less than six weeks old. There are four species of the cryptosporidium parasite that infect cattle, however Cryptosporidium parvum C parvum is the most common species detected in calves less than six weeks old.

This species of cryptosporidium can also infect humans. Calves become infected with cryptosporidium when they ingest Cparvum oocytes eggs. These oocytes reside in the environment in bedding, pasture, soil and drinking water. They are very infectious, with only 10 oocytes required to cause disease in susceptible calves.

Considering an infected calf can spread billions of eggs, it is easy to see why the disease spreads so quickly on farm. It is not only young calves with clinical signs of the disease, such as diarrhoea, that are shedding these oocytes into the environment.

Infected calves at six to seven weeks of age may show no clinical signs of infection, even though they can still produce oocytes. Adult cattle can also act as potential reservoirs for the C parvum parasite. They can also shed oocytes, but do not necessarily show any symptoms of the disease. Currently there is no vaccine available and treatment options are limited.

It is important that calves suffering from the disease are isolated and remain so for at least one week after the scouring has stopped. This should prevent the spread of eggs to other animals. See also: Pasteurising milk and colostrum reduces calf scours. Rehydration of calves is key for survival, therefore feeding one to two litres of oral electrolytes two to four times a day is recommended.

Halocur is the only product licensed in the UK for treatment of calves. This drug does not cure the disease, but should help to reduce the clinical signs and egg shedding.

Essential oils, plant extracts and fatty acids work together to reduce any gut inflammation, which can also be induced by the stress commonly experienced by young calves. Calves need gradual exposure to disease causing organisms and parasites such as cryptosporidium to allow the build up of immunity without the production of disease.

Andy has been instrumental in reducing our cases of cryptosporidium with his Crypt-Occur product alongside the use of the transition milk powder, Transformula. Scours are no longer an issue and the calves are growing on really well. It is easy to use and the recovery rate in calves is quick. If used in the early stages of crypto it is farm more effective than any other product we have previously used.

I use it as a preventative on calves from 3 to 10 days old and treat at full rate if I ever get the odd case. I have tried many other products over the years to solve this problem but they have all failed to give me the same results as I get with Crypt-Occur. It really does work. Crypt-Occur for Calves.
