Molecular basis of bacferia in clinical isolates of Escherichia coli and Salmonella species from a tertiary hospital in the Eastern Cape, South Africa.

ABSTRACT: The evolutionary and ecological success of insects is largely due to their associated bacteria and fungi that expand what are some examples of symbiotic bacteria metabolic capacities or allow them to resist stress what is a relation in math graph parasites.

Some of these associations possibly originated hundreds of millions wnat years ago and have resulted in such interdependence that in some cases the insect and bacteria may not exist separately. This has also led to a significant reduction in the genome size of bacterial symbionts and to the maternal transfer of symbionts to progeny. The study of insect symbionts has recently gained great interest and some of the biological functions of symbionts within hosts have been identified.

Scale insects or cochineals feed on the sap of plants, which is rich in carbon but poor in nitrogen and so they require symbionts to compensate for diet deficiencies. Some scale insects exxamples devastating crop pests. In this article, we review the symbionts of some scale insects focusing on carmine- and wax cochineals, which smoe commercial, art and craft interest.

In the cochineals studied we found diverse microbial communities that can synthesize what are some examples of symbiotic bacteria acids, vitamins, fix nitrogen or recycle the waste products of nitrogen metabolism.

RESUMEN: Parte del éxito evolutivo y ecológico de los insectos se atribuye a las bacterias y hongos asociados a ellos que amplían sus capacidades metabólicas o les permiten resistir estrés o parasitosis. Las asociaciones posiblemente se originaron hace cientos de millones de años y el resultado es una interdependencia que, en algunos casos, insecto y bacteria no pueden existir separadamente, lo que ha llevado a una reducción significativa de los genomas de los simbiontes bacterianos y a la transferencia por vía materna de éstos a la progenie.

Recientemente, el estudio de ae simbiontes de insectos ha cobrado gran interés y se han identificado algunas de sus funciones biológicas dentro de los hospederos. Los insectos escama o cochinillas se alimentan de la savia de las plantas, por lo que requieren simbiontes para compensar las deficiencias de su dieta, rica en carbono pero pobre en compuestos nitrogenados.

En este artículo revisamos los simbiontes de la cochinilla del carmín y de la laca, de gran interés comercial y artesanal. Palabras Clave: cochinilla, Dactylopius, fijación de nitrógeno, genomas reducidos, hongos simbióticos. DOI: Insecta insects is the most successful class of animals on Earth. Seemingly, associated microorganisms have allowed insects to adapt to almost all ecosystems on the planet Janson et al. Insects with restricted diets, such as hematophagous insects that feed on blood Rio et al.

Aymbiotic or fungi can provide insects with nutrients or metabolites that are deficient in their diet Douglas, ; Harris et al. More than 50 years ago, Buchner published his microscopic observations in a compendium of insect-associated bacteria. Earlier microscopic studies of scale insect symbionts or true cochineals were performed by Walczuch in and Buchner included them in his review. Nowadays there whhat a large research interest in microorganisms associated with insects and several types of insect symbionts are known:.

They reside inside specialized cells that are called bacteriocytes in the case of insect cells containing bacteria Baumann et al. A transcriptional factor essential for bacteriocyte development was discovered in insects Matsuura et al. Bacteriocytes are sometimes clustered in structures called bacteriomes Fig. Bacteriome location and numbers are variable. There are often two bacteriomes per insect, but there can be one to four. They are located in different regions of the insect.

Figure 1 Diagram of a dorsal section of a scale insect Monophlebidae and Coelostomidiidae familiesin which the location of bacteriomes and endosymbionts are shown. They are not essential for the survival of their host. They may also be found inside bacteriocytes. Some of them protect the insect from the attack what does qv mean in text wasps, nematodes, fungi, bacteria and viruses Xie et al.

They can also help insects in the degradation of plant toxic compounds such as monoterpenes or alkaloids, allowing insects to colonize or parasite plants. Secondary endosymbionts can protect insects from high temperatures Tsuchida et al. Others can manipulate the reproductive capacity of the host Werren et aare. It is known that secondary symbionts alter cellular functions of hosts, ranging from signal transduction to apoptosis Bentley et al.

When bacteria do not confer an increased fitness, they may what are some examples of symbiotic bacteria lost without any negative consequence for the insect Moran et al. They have been found only in some insects of the superfamily Pentatomomorpha, which includes bugs. They are often transmitted vertically by colonization of eggs, coprophagia or symbiotic capsules, but some species can be acquired from the environment by food as some of them are free-living. They also provide nutrients, degrade polymeric and toxic plant compounds and recycle nitrogen Kikuchi et al.

They contribute to the breakdown of complex chemical compounds and toxins. Gut symbionts may be vertically transferred from mother to offspring by fecal contamination, coprophagy and trophallaxis that leads to the inoculation of the gut bacteria to the progeny Salem et al. Whta, intestinal microbiota may be modified by changes in the diet.

Except for termites, the number of species in insect microbiota is smaller than that of mammals. Diversity may vary in females and males and this is the case in monarch butterflies Servín -Garcidueñas et al. In this review, we will discuss primary and secondary endosymbionts, leaving aside gut and crypt bacteria. In general, a single insect hosts what are some examples of symbiotic bacteria or more different species of endosymbionts in co-symbiosis.

Inheritability and reduced genomes are the most outstanding features of endosymbionts. Some endosymbionts share their evolutionary history with their hosts. Maternal transfer, reduced genomes and co-divergence will be reviewed in this article focusing on scale insect endosymbionts. In addition, we present the diversity of bacterial and fungal symbionts found in two models of scale insects studied in our laboratory.

Vertical transfer refers to the transmission of endosymbionts from mothers to their offspring. It is a mechanism that ensures the permanence of these bacteria in insect populations. Endosymbionts are transmitted from the time the embryos are formed and when insects are born they already carry some bacteria McFall-Ngai, By being transferred from one generation to another, bacteria can remain associated with insect species for millions of years.

Of all endosymbionts studied so far, it is estimated that the oldest is Sulcia muelleri living for over million years in a group of insects that includes cicadas, leafhoppers and planthoppers Moran et al. This means that if the genes that encode the biosynthetic pathway of a metabolite do not exist in one of the symbionts, they are probably present in other symbiont bacteria of the same insect. Table I Examples of co-symbionts with phylum indicated of What are some examples of symbiotic bacteria muellerithe primary hope inspirational quotes with images of Auchenorrhyncha.

Some bacteria may have recently become endosymbionts acquired from the transfer of endosymbionts from another insect horizontal transfer or whst the environment. When an insect acquires a new endosymbiont bacterium, the insect may gain new characteristics, such as the ability to feed on another plant Moran, It has recently been described that endosymbionts such as Wolbachia can be transferred between insects through the plants on which the insects feed Li et al.

Besides diet, endosymbionts can be exchanged by parasitoid wasps that transmit them bacterria they sting different insects Ahmed et al. Since endosymbionts live inside insects and have been transferred vertically for millions of years, they display different characteristics than free-living bacteria. They no longer retain genes essential for free living. Genes preserved include those under selective pressure and those related to the synthesis of the nutrients that the insect requires.

For this reason, endosymbionts of insects with similar diets have retained similar genes, in an example of convergent evolution. Experimental evolution studies performed in the laboratory have shown that an initial massive loss of DNA blocks occurs rapidly in bacteria Nilsson et al. Comparison between the genomes of endosymbionts and those of free-living bacteria suggests that after deletions have occurred there is a proliferation of repetitive elements what are some examples of symbiotic bacteria causes chromosomal rearrangements.

Whaf on, there is a slow accumulation of deleterious mutations. The presence of pseudogenes in the genomes of some endosymbionts suggests that their genome is still in a reduction process. They also have high rates of non-synonymous nucleotide substitutions in protein-encoding genes. Endosymbionts live in restricted environments that prevent aee with other bacteria. The strict vertical transmission has an effect on the population structure since there is whzt bottleneck with a limited number of bacteria passing to the next generation.

Successive bottlenecks during evolution reduce bacterial bacterai and increase their mutation fixation rate Moran, Table II Bacterial endosymbionts in scale insects. In the evolutionary history of insects, it seems that endosymbiont replacements have occurred several times Moran et al. The elimination of endosymbionts is also evident when bacterial genes of endosymbionts no longer present are found in the genomes of insects.

It is presumed that these genes were bacteris laterally by past endosymbionts that are no longer currently living in the insects, but have left a trace of their existence. Some insect genes of bacterial origin are transcribed in the bacteriome and may be required for the endosymbiotic relationship Husnik et al. Not all the transferred genes are the same in each species but they encode similar functions, such as peptidoglycan and amino acid biosynthesis Sloan et al.

Large genome fragments of Wolbachia have been found transferred to the chromosomes of mosquitoes Aedes aegyptivinegar fruit fly Drosophila ananassaebeetles Callosobruchus chinensis and several species of parasitoid wasps of the genus Nasonia. Some of these genes have been found to be functional Kondo et al. Extreme examples of reduced genomes are found in Nasuia and Vidania endosymbionts with genomes of and kb, respectively Bennett et how are genes determined. Endosymbionts with extreme genome reduction may need the insect contribution of essential enzymes or proteins as occurs in mitochondria.

In some cases, several of these proteins are encoded by genes that were transferred from endosymbionts to the insect Sloan et al. Remarkably, it was shown that a protein encoded by a gene of bacterial origin in an aphid, is transported to the endosymbiont Nakabachi et al. If endosymbiotic bacteria and their hosts remain associated for a long evolutionarily time, they can co-speciate or co-diverge together. In those cases, there is a phylogenetic congruence that can be traced back to a single infection event Baumann et al.

Occasionally endosymbionts have evolutionary histories different from the hosts. This is more frequent in secondary co-symbionts due to endosymbiont losses, new acquisitions of environmental bacteria abcteria lateral transfers from one insect species to another. Furthermore, it has been observed that secondary endosymbionts have a higher nucleotide substitution rate than primary symbionts Bennett et al.

Repeated sequences are found in co-symbionts such as Sodalis enterobacteria Siguier et al. It is considered that mitochondria evolved from an ancestral alphaproteobacterium more than a billion years ago and underwent a process of genome reduction Gray, ; Gray, ; Martin, that might have been similar to the evolutionary process followed by insect endosymbionts Sloan et al. Mitochondria have co-speciated with their hosts and they have transferred lots of genes to their hosts that encode proteins that are necessary for the mitochondria to carry out their metabolic functions McCutcheon, Although bacteria-insect associations are usually the most studied, about eight orders of insects are known to host fungi.

Their interactions include all types of symbiosis, such as the obligatory mutualism of cicadas Chen et al. Fungal symbionts can inhabit cavities within the insect such as the micangio in bark beetles Jones et al. Wuat, like examplws bacteria, can be transferred from the mother to her offspring bactefia as the yeast-like symbionts in the case of N.
