The document discusses methods for examining food and water microbiologically. There are three main methods discussed: culture media methods, immunoassay methods, and polymerase chain reaction (PCR) methods. Culture media methods involve culturing samples on selective and differential media to isolate and identify microorganisms. Immunoassay methods like ELISA use antigen-antibody binding to detect toxins and microbes. PCR methods amplify and detect targeted nucleic acid sequences to identify pathogens. Examining food and water microbiologically is important to ensure safety and determine processing parameters needed to meet standards.
Microbiological analysis of food products is the use of biological, biochemical, molecular or chemical methods for the detection, identification or enumeration of microorganisms in a material. Here some of the common methods have been described.

Bacterial growth curve ppt by Dr.C.P.PRINCEDR.PRINCE C P
Bacteria multiply by binary fission. The growth bacteria is measured in terms of the number of cells . total count and viable count.
osmotic environment can affect bacterial growth.
Bacteria can be grouped according to their energy source as phototrophs or chemotrophs.
Bacteria can be grouped according to their carbon source as autotrophs or heterotrophs.
Combining their nutritional patterns, all organisms in nature can be placed into one of four separate groups: photoautotrophs, photoheterotrophs, chemoautotrophs, and chemoheterotrophs.
Bacteria also need a nitrogen source, various minerals, and water for growth.
Organisms having complex nutritional requirements and needing many growth factors are said to be fastidious.

Ethanol (CH3CH2OH), or beverage alcohol, is a two-carbon alcohol
that is rapidly distributed in the body and brain. Ethanol alters many
neurochemical systems and has rewarding and addictive properties. It
is the oldest recreational drug and likely contributes to more morbidity,
mortality, and public health costs than all illicit drugs combined. The
5th edition of the Diagnostic and Statistical Manual of Mental Disorders
(DSM-5) integrates alcohol abuse and alcohol dependence into a single
disorder called alcohol use disorder (AUD), with mild, moderate,
and severe subclassifications (American Psychiatric Association, 2013).
In the DSM-5, all types of substance abuse and dependence have been
combined into a single substance use disorder (SUD) on a continuum
from mild to severe. A diagnosis of AUD requires that at least two of
the 11 DSM-5 behaviors be present within a 12-month period (mild
AUD: 2–3 criteria; moderate AUD: 4–5 criteria; severe AUD: 6–11 criteria).
The four main behavioral effects of AUD are impaired control over
drinking, negative social consequences, risky use, and altered physiological
effects (tolerance, withdrawal). This chapter presents an overview
of the prevalence and harmful consequences of AUD in the U.S.,
the systemic nature of the disease, neurocircuitry and stages of AUD,
comorbidities, fetal alcohol spectrum disorders, genetic risk factors, and
pharmacotherapies for AUD.
Flu Vaccine Alert in Bangalore Karnatakaaddon Scans
As flu season approaches, health officials in Bangalore, Karnataka, are urging residents to get their flu vaccinations. The seasonal flu, while common, can lead to severe health complications, particularly for vulnerable populations such as young children, the elderly, and those with underlying health conditions.
Dr. Vidisha Kumari, a leading epidemiologist in Bangalore, emphasizes the importance of getting vaccinated. "The flu vaccine is our best defense against the influenza virus. It not only protects individuals but also helps prevent the spread of the virus in our communities," he says.
This year, the flu season is expected to coincide with a potential increase in other respiratory illnesses. The Karnataka Health Department has launched an awareness campaign highlighting the significance of flu vaccinations. They have set up multiple vaccination centers across Bangalore, making it convenient for residents to receive their shots.
To encourage widespread vaccination, the government is also collaborating with local schools, workplaces, and community centers to facilitate vaccination drives. Special attention is being given to ensuring that the vaccine is accessible to all, including marginalized communities who may have limited access to healthcare.
Residents are reminded that the flu vaccine is safe and effective. Common side effects are mild and may include soreness at the injection site, mild fever, or muscle aches. These side effects are generally short-lived and far less severe than the flu itself.
Healthcare providers are also stressing the importance of continuing COVID-19 precautions. Wearing masks, practicing good hand hygiene, and maintaining social distancing are still crucial, especially in crowded places.
Protect yourself and your loved ones by getting vaccinated. Together, we can help keep Bangalore healthy and safe this flu season. For more information on vaccination centers and schedules, residents can visit the Karnataka Health Department’s official website or follow their social media pages.
Stay informed, stay safe, and get your flu shot today!

Introduction
Many have been interested in Tom Selleck health. not only because of his enduring presence on screen but also because of the challenges. and lifestyle choices he has faced and made over the years. This article delves into the various aspects of Tom Selleck health. exploring his fitness regimen, diet, mental health. and the challenges he has encountered as he ages. We'll look at how he maintains his well-being. the health issues he has faced, and his approach to ageing .
Early Life and Career
Childhood and Athletic Beginnings
Tom Selleck was born on January 29, 1945, in Detroit, Michigan, and grew up in Sherman Oaks, California. From an early age, he was involved in sports, particularly basketball. which played a significant role in his physical development. His athletic pursuits continued into college. where he attended the University of Southern California (USC) on a basketball scholarship. This early involvement in sports laid a strong foundation for his physical health and disciplined lifestyle.
Transition to Acting
Selleck's transition from an athlete to an actor came with its physical demands. His first significant role in "Magnum P.I." required him to perform various stunts and maintain a fit appearance. This role, which he played from 1980 to 1988. necessitated a rigorous fitness routine to meet the show's demands. setting the stage for his long-term commitment to health and wellness.

Recomendações da OMS sobre cuidados maternos e neonatais para uma experiência pós-natal positiva.
Em consonância com os ODS – Objetivos do Desenvolvimento Sustentável e a Estratégia Global para a Saúde das Mulheres, Crianças e Adolescentes, e aplicando uma abordagem baseada nos direitos humanos, os esforços de cuidados pós-natais devem expandir-se para além da cobertura e da simples sobrevivência, de modo a incluir cuidados de qualidade.
Estas diretrizes visam melhorar a qualidade dos cuidados pós-natais essenciais e de rotina prestados às mulheres e aos recém-nascidos, com o objetivo final de melhorar a saúde e o bem-estar materno e neonatal.
Uma “experiência pós-natal positiva” é um resultado importante para todas as mulheres que dão à luz e para os seus recém-nascidos, estabelecendo as bases para a melhoria da saúde e do bem-estar a curto e longo prazo. Uma experiência pós-natal positiva é definida como aquela em que as mulheres, pessoas que gestam, os recém-nascidos, os casais, os pais, os cuidadores e as famílias recebem informação consistente, garantia e apoio de profissionais de saúde motivados; e onde um sistema de saúde flexível e com recursos reconheça as necessidades das mulheres e dos bebês e respeite o seu contexto cultural.
Estas diretrizes consolidadas apresentam algumas recomendações novas e já bem fundamentadas sobre cuidados pós-natais de rotina para mulheres e neonatos que recebem cuidados no pós-parto em unidades de saúde ou na comunidade, independentemente dos recursos disponíveis.
É fornecido um conjunto abrangente de recomendações para cuidados durante o período puerperal, com ênfase nos cuidados essenciais que todas as mulheres e recém-nascidos devem receber, e com a devida atenção à qualidade dos cuidados; isto é, a entrega e a experiência do cuidado recebido. Estas diretrizes atualizam e ampliam as recomendações da OMS de 2014 sobre cuidados pós-natais da mãe e do recém-nascido e complementam as atuais diretrizes da OMS sobre a gestão de complicações pós-natais.
O estabelecimento da amamentação e o manejo das principais intercorrências é contemplada.
Recomendamos muito.
Vamos discutir essas recomendações no nosso curso de pós-graduação em Aleitamento no Instituto Ciclos.

2. Why we need to examine food and water?
1. to know the level of sanitation used during
handling.
2. to know whether the food / ingredient meet
the normal standard/ guidines.
3. 3. The examination of raw ingredients also
provide information about heat processing
parameters that would be necessary to meet
the microbiological standards.
4. To determine the source / load/ type of
microorganisms in foods and water.
4. Criteria for choice of methods
1. Accuracy
2. Sensitivity
3. Easy of implementation
4. Equipment/ operating cost
5. speed
5. Common Test Methods
• Although a wide range of technologies are used for the
identification and verification of microorganisms, but among
these technologies, three types of method are commercially
popular.
These are:
• Culture Media,
• Immunoassay
• Polymerase chain reaction.
6. Culture Media
• Traditionally, cultural techniques have been the tests of choice
for both ready-to-eat foods and fresh produce.
• However, today immunoassay and PCR methods are more
accepted than cultural methods, because recent
developments of newer testing methods and validation
studies have demonstrated that cultural methods aren't
suitable for all food groups.
7. • The traditional way of detecting and identifying
bacteria from food, or other samples, is based
on:
- Culturing
- Enumeration
- isolation of presumptive colonies for further
identification analysis.
• If necessary, the food sample must be
homogenized, concentrated, and/or
pre-enriched prior to culturing.
8. • Bacterial cells can become injured or viable but
nonculturable (VNC) due to the sublethal stressors, such as:
- Heat
- cold
- acid
- osmotic shock during the food processing steps.
• These bacterial cells still pose a threat in the food industry
and therefore, methods to improve the detection levels of
these injured cells have been developed.
9. The pre-enrichment of the bacteria in a
food sample can be performed by a:
- non-selective
- or selective broth culture
- or by the selective agar overlay
technique to resuscitate the injured cells.
10. • Another manner in which the detection levels of
viable cells can be increased is by concentration of
the food sample by filtration or centrifugation prior
to plating.
11. • The pre-treated food sample can then be plated on:
- non-selective
- selective
- differential media
• Non-selective media or standard methods agar, such as the
aerobic plate count, can be used to detect and count the
amount of bacteria in the sample.
12. • Selective medium contains a compound, such as an antibiotic,
bacteriocin, a growth nutrient, which selectively inhibits the
growth of specific microorganisms.
• Eg: PEMBA medium ( polymyxin pyruvate egg yolk mannitol
bromothymol blue agar ) for the isolation and enumeration of
Bacillus cereus in foods. Its able to detect small numbers of
Bacillus cereus cells and spores in the presence of large
numbers of other food contaminants.
13. • The third type is a differential medium which contains an indicator,
such a chromogenic or fluorogenic substrate, which
differentiates bacteria by various chemical reactions carried out
during growth.
• By incorporating fluorogenic or chromogenic enzyme substrates
into a selective media, identification of microorganisms can be
done directly without further subculturing or biochemical tests.
• These culture media are based on bacteria producing specific and
exact enzymes for substrates.
• As the enzyme then acts with the substrate( fluorogenic or
chromogenic) the bacterial growth will fluoresce or change color,
respectively.
14. A fluorogenic medium used to detect and
enumerate E. coli and coliforms.
Chromogenic Media
for Salmonella detection from food
samples
15. • Even though the culture methods are time consuming (Time to
attain results can range from twelve hours to more than a week)
and laborious.
• the isolation and purification of microorganisms allows for further
subtyping analysis and for storage in culture collections.
• The more conventional methods for further subtyping of bacteria
include the study of the phenotypic characteristics of the
microorganisms.
• These phenotypic methods include:
- Biotyping
- serotyping,
- phage typing .
16. • In biotyping some aspects of bacteria are investigated such
as:
- the biochemical growth requirements.
- environmental conditions (pH, temperature, antibiotic
resistance).
- physiological (colony and cell morphology, cell wall
composition by microscopy and membrane composition such
as by fatty acid analysis)
17. • while serological and phage typing concentrate more on
the surface structure differences of bacteria.
• Phages are not only useful in subtyping bacteria, but also in
detecting pathogens directly from foods .
• However, these phenotypic typing methods are limited
since microorganisms are capable of suddenly altering
their phenotypic characteristics due to environmental
changes or genetic mutations.
• Therefore, identification by genotypic characteristics has
been developed to avoid these problems that can occur
with phenotypic methods.
18. Immunoassay
• Immunoassays are based on the specific bindings between
antigens and antibodies.
• Historically, they were used mainly in clinical diagnostics, but
are becoming popular in rapid detection of microorganisms
from food samples.
19. • Several types of immunoassays have been used in food
sample analysis, including:
- enzyme linked immunosorbent assay (ELISA)
- immunodiffusion tests
- immunofluorescent microscopy
- immunomagnetic separation
- immunoprecipitation.
20. • Currently, a couple of commercial immunoassay-based
detection systems are available to detect toxins or microbes
in the food system, for example:
- the ImmunocardSTAT! E. coli O157:H7detection kit.
21. • Because of its accuracy and automation capability, most
commercial immunoassay kits for food testing are based on
ELISA.
• ELISA usually takes 1 h for toxin and 20-36 hours for cells .
• However, ELISA still has its limitations. For instance, without
enrichment, the sensitivity of ELISA may not be enough to
detect the microorganisms at very low level.
• Therefore, the time required for sample analysis including the
pre-enrichment and/or enrichment procedures could be
much longer than ELISA itself.
22. Polymerase Chain Reaction (PCR)
• Polymerase chain reaction is the amplification of a nucleic
acid target sequence.
• The targeted sequences can be a specific gene or repetitive
areas in the sequence .
• For foodborne bacterial pathogens, commonly targeted DNA
areas are :
- virulence factors
- Toxins
- cellular metabolites
- multicopy ribosomal RNA.
23. • The PCR-based techniques have also been developed for
screening of genetically modified organisms and their
derived materials in foods .
• Post- PCR detection methods vary from gel electrophoresis
and usage of specific nucleic acid probes. In some cases,
probes simplify the detection of the PCR product, in the
similar way as gel electrophoresis.
24. • some PCR use DNA primers and
fluorescent probes specific to the
target organism in the same
reaction mix.
•Detection of a fluorescent signal
for the targeted amplified
sequences indicates the presence
of the pathogen in the sample
being tested.
