Do Ants Carry Disease that can endanger your health

DO Ants Carry Disease

Do ants carry disease? When most people think of insects that carry disease they think of roaches, rats, fleas, ticks, mosquitoes and bedbugs. But most no one I have ever met has ever expressed a concern for ants transmitting diseases.

This is due in part because most people don’t understand pathogens or bacterial and viral diseases transmitted by insects, we are all ignorant in what we don’t understand and therefore never give consideration to it, this is normal if its not front page news or a major epidemic like
Dengue Fever, West Nile virus or Ebola most of society goes on about their lives with no regard for these matters.

But when you spend most of your life doing research on pests and diseases talking to entomologist and pathologist you have an advantage over most of society and consider these issues more seriously.

I will give you simple scenario an ant colony infests you home an create a nest in your bathroom since ants need food, water and shelter to live and they can go without food but cannon go without water your bathroom is a perfect place to live.

They crawl around in your toilet for water and crawl to your toothpaste for sugar food. See the problem now. Whatever pathogen was in your toilette has been carried back to your toothpaste and you brush your teeth and could potentially get sick if it transmits the right bacteria.

So the next time you see ants you wont think oh it’s just ants they are harmless, thinks again!

Ants have been linked with respiratory allergies and asthma

Respiratory allergy to the indoor ant (Monomorium pharaonis) not related to sting allergy

February 2005 Volume 94, Issue 2, Pages 301–306

Conclusion:

Ants can induce IgE-mediated bronchoconstriction regardless of sting in sensitized patients. Ants should be taken into consideration as a cause of respiratory allergy in patients living in homes with visual evidence of infestation.

Many ant species displaying synanthropic behavior that have successfully dispersed in urban areas can cause problems in hospitals by acting as bacterial vectors.

In this study, we encountered bacteria on ants collected at the Universidade Federal de Uberlândia hospital, in the campus and at households nearby.

The ants were identified as Tapinoma melanocephalum (Fabricius) and Camponotus vittatus (Forel) (Hymenoptera: Formicidae) and the bacterial strains found here belong to the group of the coagulase-positive staphylococcus, coagulase-negative staphylococcus and gram negative bacilli, including antimicrobial drug-resistant strains.

An investigation of the bacteria found in the ants and in the environment revealed that some ants carried non-isolated bacteria from the same environment and with high levels of resistance, evidencing the transmission potential of these insects.

ABSTRACT

The presence of antimicrobial-resistant bacteria and carried by ants isolated from hospitals was investigated in Campos dos Goytacazes, RJ, Brazil. Three health institutions were visited from 2001 to 2002 and samples were collected within critical areas of medical care based on criteria of greater risk of patient hospital acquired-infection.

Four ant species were identified, Tapinoma melanocephalum (Fabricius)(63.1%), Paratrechina longicornis (Latreille)(21.1%), Monomorium pharaonis (L.)(10.5%), and Solenopsis saevissima (S. Smith)(5.3%) carrying 21 species of bacteria.

The tests for bacteria species identification and antimicrobial-resistance profile were carried out by using standardized kits and evaluated by automated equipment. Among the bacteria isolates, some were considered multiresistant isolates, including genera Acinetobacter, Streptococcus, Gemella, and Klebsiella.

For Enterobacter antibacterial analysis the disk diffusion standard method was used. The results suggest that there are risks for patients which seek for health assistance in the hospitals studied, and the presence of emerging bacteria isolates in hospital carried by ants must be considered.

ABSTRACT

Introduction

We studied the richness and abundance of ant species, their bacteria and the bacteria isolated from patient clinical samples. Methods Ants were collected with baited traps at 64 sites in a public hospital in São Luis, State of Maranhão, Brazil.

Results In total, 1,659 ants from 14 species were captured. The most frequent species were Crematogaster victima, Solenopsis saevissima, Tapinoma melanocephalum, Camponotus vittatus and Paratrechina fulva. Forty-one species of bacteria were isolated from the ants and 18 from patients.

Conclusions

Ants are potential vehicles for pathogenic and opportunistic bacteria, and they can represent a risk factor in nosocomial infections.
